I'm not sure if this is normal or not. I just got my Cingular 8125 and the wifi is very slow. I don't know how to measure the actual speed but for instance on my broadband connection, going to Google.com opens up in about a second. On dial up it takes about 5 seconds. However, on my phone using wifi, it takes about 20 seconds. When using wifi on my laptop, it is comparable to my broadband speeds my router is connected to.
I have pretty slow GPRS service as well and wifi is comparable.
I get the same slow speed on 802.11b as well as 802.11g networks (g network with registry hack)
Is this normal? The wifi speeds with the unit brand new out of the box was very slow. I flashed the rom and even overclocked to 240, the wifi internet is still painfully slow. I don't really find this useable. If I go to a page with images and such it can take a minute or so.
Anyone have any suggestions? Are others getting good speed on wifi. I tested by watching a streaming video and the speed shown on the bottom of windows media was 18k.
Were my expectations too high? Is there a setting I have incorrect?

Always best to be sure that you are actually using the wifi connection - Try disconnecting the gprs first before you connect to wifi. I have an issue where if I leave my gprs connection enabled all the time it takes precedence over my wifi no matter what.

Tried that but still no luck. When connected by wifi, I see the little wifi icon on the title bar. When connecting to GPRS, it shows the E and actually a pop-up saying it is connecting to GPRS. This part is actually working great. Uses wifi by default when wifi is on and GPRS is not.
I did try to disable GPRS entirely but still get the same slow results.
I also changed the wifi setting to maximize performance instead of save battery life. Didn't seem to matter.
I may experiment with Opera Mini or something to see if I can get some improved speeds.
no problems with wifi here. getting a faster connection than GPRS, even at hotspots.
I had a problem with my wifi connection in that the DHCP server giving out an incorrect address for one of the DNS servers. This made the wifi slow, because Internet Explorer kept on trying to lookup the IP of a host using the broken DNS, and then falling back to the second in the list.
You try specifying a DNS server manually to diagnose the problem.
Cingular 8125 WiFi Fix that works!
Believe it or not the support for this product from HTC, the mfgr, is great and fast! That being said, I like most users have spent days hunting for solutions to the problem and you will not find them anywhere. But here is the solution:
First you must have an unlimited account for data usage or forget your WiFi...well at least simply. Also, you must get Cingular to flip a switch for your 8125 to automatically switch from WiFi to GPRS and back depending on what is the best signal. It works great once the switch is set.
The only way I found to do this was to call support and make sure you get to the HTC support group. They will guide you quickly through getting setup but you must tell them about the switch so they call Cingular and have the switch set. For some reason Cingular, no surprise, does not seem to know about this when they sell you the plan and the phone.

Thank you so much. This sounds like the solution I'm looking for. So are you saying to call HTC support and they will contact Cingular to have the switch set on my behalf?? Or do I just call Cingular and tell them to "turn the switch on"?
I do have an unlimited GPRS for data usage.
what a crock of steaming brown stuff :x .... what exactly does wifi have to do with your telco? ... nothing. There maybe some registry entry that Cingular have set when the device ships which causes poor WiFi speeds but your GPRS data plan has nothing to do with WiFi data, unless you are talking about connecting to Cingular WiFi hotspots. The only changes needed will be on your device not within the Telco network.
before calling support, try this:
Go to comm mgr and turn off the phone. Then turn on WiFi and let it connect. Check your speed with www.2wire.com. If your speed is still slow, and another PC connected to that HotSpot isn't (test the PC with 2wire also) then your 8125 is bad.
Using the WiFi icon v.s. the "E" icon is no way to determine what wireless system you're using btw...

Ok, I tried 2wire. My laptop connected to my wifi network and clocks in at 3.2Mbps and my 8125 is showing 221 kbps. multiple tests showed 228, 205, 220). Perhaps it is unrealistic to expect similar speed as my laptop.
I turned the com manager phone back on and connected via GPRS and the speed test came back at 64.8 kbps.
So it does look like this method is working. I can live with 221 kbps.
By the way, I emailed Cingular and HTS. I got the following response from Cingular:
Thank you for contacting Data Support!
There is an additional setting that you need to enable/disable manually every time you switch between GPRS and Wi Fi, please take a look at it:

I think it's always going to be slow because of the way the phone is designed. Probably small bus interface. My friend has a 6700 wich cpu wise is pretty much the same based on comparison but his is much faster through wifi.
"I think it's always going to be slow because of the way the phone is designed. Probably small bus interface. My friend has a 6700 wich cpu wise is pretty much the same based on comparison but his is much faster through wifi."
No no no no no no and no.
small bus interface? for heavens sake... you have heard that there is something called a "bus" inside computers and that it is used to "transfer data" and this "bus interface" is small in the qtek so it is a viable candidate to blame slow transfers on.
no.
any memory bus designed after 1980 is capable of 200kbit transfers.
the main reason for the horrid speed of the 9100 is the stupid software design where every system call in a program gets interrupted by the os which in turn, after checking who-knows-what, in the name of "security" and "stability", and then executed. Of course this hinders performance dramaticaly without affecting stability and security a single bit: it still crashes. the difference is that it is also slow.
I'm running Xelencin's custom 2.17 ROM for T-mobile on my 8125. His ROM sets the device up to work with an 802.11 g wifi connection. I kid you not - I have measured 900 to 1200 Kbps on my wifi at home (comcast) and at work (T1). It's blazing fast.
To measure your speed, go to www.dslreports.com. Click on the lowfi version at the top of the page. Then click on speed test. Then choose either 600K or 1 MB and then let it do the test.
You may have some setting wrong.
I have an 'adhoc' wireless network (running at 11Mbs) and i stream large lossless (FLAC) audio files to my Squeezebox 3 wireless music player with no issues whatsoever.
However, the MDA can't cope at all. FLAC files play great from the MiniSD, but wifi performance is worse than terrible.
Yes, the wifi speed of the MDA is s**t.
That said, if anyone has any tips on how to increase perfomance please let me know!
Thanks.
My Wifi would not work at all when I updated my ROM but this utility fixed that and sped things up. I recommend backing up your device before executing because I have only tried this on QTEK 9100 with a beta 2.8 ROM.

Excuse me for my ignorance... But then how do you explain that the 6700 can handle 700kb wireless while 9100's usually around 220kB? The Intel proc on the 6700 seems comparable to the Omap,no?

What exactly does this cab change?
Reconfiguring DNS may make a significant improvement?
I came across your post after my own concerns with my I-mate K-Jam (Wizard) WiFi performance. My GPRS connection was at least twice as fast.
My problem was that is was taking at least 30~60 seconds to locate a web page and another 10~15 seconds to open the page. Once connected it seemed to work OK but operation via GPRS was still faster.
My K-Jam has a ROM that permits G connection and my AP is set to G only. After reading all the articles in this post (and others), I ran the 600K download at DLSreports.com. To my surprise, my download rate was actually + 500kbit/sec which lead me to believe I might have DNS issues.
I used vxUtil (http://www.cam.com/windowsce.html) to check my DNS settings. My primary DNS being picked up from my DSL modem was the DSL modems gateway address which works fine in my Toshiba laptop. My secondary DNS was my ISP's backup.
I reconfigured my DSL modems DHCP server so that the DNS servers being dished up to my K-Jam are my ISP's primary and secondary servers and I performed a soft reset.
The speed increase was substantial! Pages are located and opened within 5 seconds now making my WiFi connection useable.
This may be worth a try for others with similar issues?
Did anyone else notice this registry entry?
[HKLM\Comm\TIACXWLN1\Params]
"EnableElpMode"=dword:00000000
If I'm not mistaken, the TyTn has a TI ACX100 WiFi chip, and this chip has TI's "Enhanced Low Power(tm) Technology". I've enabled it on my TyTn, and so far it seems to do no harm. I'll have to see if my battery power improves over the next week.
Correction...
Ah, the htc TyTn has TI's TNETW1250 chip. My mistake.
In any case, I think the EnableElpMode (if it really does work) would be a good thing. Also, I've seen a few webpages suggesting an additional key:
"dot11SupportedRateMaskG"=dword:00000008
Apparently this key tells the driver it's okay to do any 802.11g speed. I'm going to go find out!
let us know how it goes....
1st set of test results
First, I should detail the equipment I'm using.
My wifi router: D-Link 624.
My phone: htc TyTn, QTEK ROM 1.35.255.2 (Radio 1.18.00.10)
My laptop: IBM Thinkpad T22, w/ Hawking Techmologies HWC54D wifi card, Win2k.
My PC: P4 2.4GHz, asus P4P800 (has Gb lan), WinXP.
Results so far: (using http://www.bandwidthplace.com/speedtest, and sitting right next to my DI624)
PC: 5.3 Mb/s
Laptop (w/wifi): 3.4 Mb/s
TyTn: ~250 kb/s
Notes:
In one test I set the DI624 to use 802.11g only. Without any registry tweaks, the TyTn connected up just fine. Therefore, I suspect that the dot11SupportedRateMaskG key is no longer needed.
Curious to see if I could boost the TyTn's wifi speed, I began fiddling with all of the different registry settings under that heading (listed above). The wifi speed always hovered in the 250 kb/s range. It seems as though none of those settings significantly changed the wifi speed.
There was one key that did make a big difference in the time it take to actually connect up to the wifi router. Setting "dot11ShortPreambleInvoked" to 1 greatly sped up the time from wifi-off to wifi-connected-and-ready. (My DI624 was also configured for a short preamble.) Without the short preamble, it was taking between 10-30 seconds for the TyTn to connect up. With the short preamble it's between 5-10 seconds.
(Side note: The "Testmode" key didn't seem to do anything - at least I didn't see any difference when I set that to 1.)
One other key that did make a small difference:
[HKLM\Comm\Tcpip\Params]
"TCPWindowSize"=65536
I played around with this key, and it seems like setting it to 4096 "optimized" it just a bit. I got around 270 kb/s with that setting. Setting it bigger (say, 256k) slowed things down (~240 kb/s), while setting it smaller (say, 1k) really slowed things down (~170 kb/s!).
I'm going to continue fiddling around with the settings and report back again. It just seems to me that the TyTn should be able to achieve a wifi speed at least above 1 Mb/s. I would appreciate it if everyone else would check their wifi speed and post the results here as well.
p.s. If anyone knows of a PocketPC utility that can show detailed wifi connection information (such as speed, frequency, protocol, etc.) please let me know!
250 kpbs, that cant be correct? can it?
that would mean that HSDPA is faster than hermes wifi? I will test mine when my wife gives it back to me, im grounded for the holiday season. lol
something is terribly wrong here......
yes, there is something wrong here... I think you need to turn on flight mode before you run your wireless test again, and here is why... On my phone i have my data connection set to always on. If i turn on wifi then my data connection doesnt disconnect and will result in low speeds since its not using the wifi. If i turn mine on flight mode then run tests then everything is good. Here is my results using the same site as the OP
PC = 1.9
phone = 1.4
I am using a 3meg adsl pipe with a wireless SMC router with mac filtering, regular wep, and a static set up on the LAN side.
Progress!
I changed my wifi speed test to: http://www.dslreports.com/mspeed
Surprisingly, that speed test reported 1647 kb/s for my TyTn!
Fiddling with the TCPWindowSize value, it seems that 64k is optimum - well, at least with the dslreports test.
i usually use dsl reports, but i wanted to maintain some kind of constant for your testing
Wireless settings / b-g connections
Hi, I;ve just got a TyTn but it won't connect to my Netgear 802.11g router?? Is it b-only? Is there a hack (like for the Universal) which would enable me to connect to g networks? Would I still be able to connect to b-networks?
Thanks!

My TyTn is fairly new (bought last month) and I can configure my DI624 to 802.11g only, and connect up just fine. What ROM version does your TyTn have? I'm on the QTEK 1.35.255.2 ROM. If you TyTn is right-out-of-the-box, it's probably got the QTEK 1.18.xxx.x. If that's so, you should consider unlocking it and upgrading it to one of the latest ROMs.

The htc TyTn (Hermes) has the TI TNETW1250 wifi chip. This chip is 802.11g capable.

You can try adding this registry key (although I'm not sure it will do anything on the TyTn):

Yes. Wifi chips that support 802.11g always support 802.11b (AFAIK).
Good luck!

Yeah, after checking out several speed test websites, I'm beginning to doubt the one on bandwidthplace. Actually, while testing out several other speed test websites using my PC, I've gotten a smattering of different speeds reported. Most seemed to be within reason and about what I expected, but a few were either obviously too slow or absurdly too high. (Ony reported above 100 Mb/s downstream, even though my cable modem is a DCM-202!) The dslreport site seemed to be believable to me, so I'm sticking with it for now.
If it makes you feel better i work for AT&T in the DSL maintenance department and have for 6 years.. anytime i have anyone that reports slow speed issues i always take them to dslreports and use those speedtests.. they seem to be the most reliable that i have found..
Okay, I'll trust dslreports' speed test then!
So now the question is: Does a wifi speed of ~1600 kb/s sound "right" for the TyTn?
What makes me wonder is that when I run the dslreports speed test on my laptop via wifi, I get ~3.2 Mb/s. So I know my DI624 can pump out the bits! (Well, for 802.11g's max of 54 Mb/s, that's still kinna lame.)
I've pretty much exhausted all of the registry settings I can find. Got any others I can/should look into?
there are other things you need to take into account, the processor, the amount of ram, etc.. when you run a speed test it rely's on your pc to process the information as it comes down the pipe... if you really wanted to test it you could build a pc that resembled the phones specs and run a speed test and see what you get.. i would make a bet that it would resemble the same results

Is 1.6 Mb/s the best TyTn can do?
Well I've fiddled with all the registry settings I could possibly fiddle with, and dslreports won't show anything above 1.6 Mb/s for on my TyTn (using PIE).
Has anyone gotten anything higher with their TyTn?
Issue solved !
My access point/wireless router (ASUS WL700gE) has a setting called "Data rate (Mbps)" which is factory set on "Auto". Manually setting this to 54Mb/s causes the Blackstone to connect to this speed.
After a little digging and testing, I've come to the following conclusion: the phone tries to connect to the lowest possible speed permitted by the network, probably to conserve power. If your access point allows connections to 1Mb/s, the phone will connect to this speed. In light of this fact, I've set up this parameter as 36Mb/s, since I think it's the value which best balances performance versus power consumption.
Here is the original post, with the original problem, for reference:
Hi all,
I'm a Touch HD/Dutty ROMs 6.[1|5] user. I've got this problem: regardless of the underlying WinMo version, wireless network receive rate seems to be always 1Mb/s. I've tried it in different locations, with and without walls between the HD and the access point, different TX power settings on the AP, different channels (in order to avoid interference), different advanced WiFi settings on the AP, in short: every possible scenarion. I'm inclined to suspect the radio, but I've got the 1.14 version and I wouldn't think that such a blatant bug as a limit of the RX rate would have made it to that version.
Anyone having the same problem ? Better yet, anyone having had the same problem and found the solution ?
Thanx for any pertinent suggestion !
hi, i'm not a guru, but i know that a 54mbit wireless network should transfer data at about 1.5mbyte per second the other bandwidth is used for manteining connecction between the devices so the real trhoughput is 1.5 mbyte per second. That make me think that there is nothing wrong with your phone.
gteets,
Nicola

you're getting 1 megabyte per second or 1 megabit?
The speed is 1 Megabit per second. I'm not speaking about "download speeds", it's about the connection speed, which *should* be as close to 54Mb/s as possible, since the internal wireless adapter is 802.11g compatible. Please note the lowercase b in Mb/s, as opposed to upper case B, which would mean bytes .
think when they say "802.11g compatible"
they mean the device will not force the whole wifi network down
to 10Mbit like slower devices normaly do
think qualcomm's wifi performance is just that slow in general
TC,
How hot does it get when you use it 54mb/s?
Also, I strongly advise against using it at that speeds whilst charging the device simultaneously.
Cheers.

Well, I haven't tried it at 54 Mb/s, I just saw it working and then set the router on 36 (exactly because I was afraid of overheating). What is pretty neat, though, is that I watched an entire movie, shared on the LAN, from my desktop computer, with the wireless connected at 36 Mb/s, without any serious overheating. The bottom part of the device was, indeed, a little warm to the touch, but that happens even when watching movies from the SD card, probably it's the video controller at work. I regret not checking the battery, before and after, but I'll repeat the experience and I'll post the results.

Pap,
Thank you very much for checking. I look forward to seeing how hot it gets. I've noticed that even just from casual browsing under stock settings with the WIFI set to best battery, the phone is noticeably hotter even just after 20 ~ 30 minutes of surfing. I can only imagine what 54/mbs would do to the phone. Lawl.
Cheers.
I had the same symptoms, especially with WinMo 6.5 (I've even complained about this in a few threads). The phone was overheating like crazy, even when I was just reading e-books (so no data connection, no phone, no video applications, just a text displayed on the screen). What changed everything was an advice from another forum member (makbil): never forget to hard reset after flashing. After my latest flash, I hard reset the device and it's working perfectly.
Coming back on the topic of wireless networking, I would like to add that, after perfoming the tweak from the first post, I noticed a marked decrease in connection time. Now, the connection to the wireless network after I turn on the device (from sleep state, not from a total poweroff, of course) is almost instantaneous.
Oh, and I promised to check the battery consumption with intensive usage of WiFi. I tested with 2 succesive playbacks of the same 45 minutes video, first playback from SD card, second playback from a Windows share on my desktop computer. In both instances the battery was 100% full.
The results: At the end of the SD card playback, the battery meter was still indicating 100%. At the end of the LAN playback, the battery was 98%. No additional heating between the two tries.
Hi all,
Ive been having a problem whereby my twitter and facebook feeds wont refresh after browsing the net for 15 mins or so on WiFi.
They work without problems based on phone signal but when using WiFi its as if the signal just drops out even though it says not, and the browser will work just not facebook/twitter. A phone restart or toggle off/on of WiFi doesnt fix the problem.
Im on 2.3.3 and firmware version KE2.
Any ideas or anybody been having the same issue? Ive done some searching but cant find any help...

It may be a defect on your phone. Try bringing it back to the shop and ask for a replacement if you can repeat the issue on their Wi-Fi.
And I wouldn't really recommend on getting a Sensation because of Wi-Fi issue because the Sensation has a worse "death grip" issue (YouTube that and you will see quite a lot of videos on that), other than a very small 1.5GB internal storage/

Hi all,
Ive been having a problem whereby my twitter and facebook feeds wont refresh after browsing the net for 15 mins or so on WiFi.
They work without problems based on phone signal but when using WiFi its as if the signal just drops out even though it says not, and the browser will work just not facebook/twitter. A phone restart or toggle off/on of WiFi doesnt fix the problem.
Im on 2.3.3 and firmware version KE2.
Any ideas or anybody been having the same issue? Ive done some searching but cant find any help...

Does your wifi routes data through a proxy. If yes apps wont be able to connect to the internet on wifi, the browser can.
This is an android issue so shifting to sensation wont help.
Hello Guys,
I can think of two possibilities.. Cause, I had somewhat the same problem in the earlier Galaxy S (I am now on Galaxy SII).
First Scenario :
Both Facebook and Twitter have a refresh timing option under Settings. You must set it to minimum. (For facebook, minimum refresh is 30 mins and for Twitter, Its 15 Mins).
Second Scenario :
I assume that you are using WiFi and I also assume that you have a repeater installed. In that case, you must tinker with the Network WAN settings of your repeater. Typically, the broadband "modem" is set to MTU = 1500 and the "Repeater" MTU is also set to 1500. This causes some problem in uploading data. Now, as facebook and twitter ( as also Android Market ) sends some data first and then downloads data, if the sendng is problamatic, the downloading of data would also not be good. ( A typical way to check it is to try uploading some test snap on facebook. If the test snap is uploading, then your home Wifi is working all right). However, if the picture uploading is not getting through, try to reduce the MTU. This guide will help you :-
"Max MTU: How do I find mine?
The MTU setting controls the maximum ethernet packet size your PC will send (you did know the Internet works in packets, didn't you?). Why a limit? Because although larger packets can be constructed and sent, your ISP and Internet backbone routers and equipment will chop up (fragment) any packets larger than their limit. These parts are then reassembled by the target equipment before reading. This fragmentation and reassembly is not optimal.
MTU and Windows and Defaults
Unless otherwise set, Windows defaults MTU to 1500, or a lower value of 576 for external networks. 1500 is OK unless you are running PPPoE, want to use IPSec (Secure VPNs) or both, then it's too big. 576 is not efficient for the broadband/Internet; it's too small.
Finding the largest MTU, by EXPERIMENT
If your MTU is too low already, maybe 576, the following method will not be able to detect whether you can switch to an optimal size. So first follow "CHANGING MTU for PPPoE" to reset MTU to 1500, reboot and then come back to this!
The best value for MTU is that value just before your packets get fragmented. How do you find that out? By using Ping at an command prompt.
Windows 2000/XP users:
Go to Start/ Programs/ Accessories/ Command Prompt and type the following:
ping -f -l 1472 www.dslreports.com
(That is a dash lower case "L," not a dash "1." Also note the spaces in between the sections.)
Linux users:
ping -s 1472 www.dslreports.com
OS X users:
ping -D -s 1472 www.dslreports.com
Linux and OS X commands are case sensitive.
Press Enter. Then reduce 1472 by 10 until you no longer get the "packet needs to be fragmented" error message. Then increase by 1 until you are 1 less away from getting the "packet need to be fragmented" message again.
Add 28 more to this (since you specified ping packet size, not including IP/ICMP header of 28 bytes), and this is your MaxMTU.
Note:If you can ping through with the number at 1472, you are done! Stop right there. Add 28 and your MaxMTU is 1500."
I hope with the above, the prroblem gets sorted. If you succeed, please leave your experience here...
Regards.
Hi all,
Thanks for your replies.
Neither facebook nor twitter work at all on wifi now. I've figured out that they DO work on wifi on friends/family routers, just not mine!
Whats weird is facebook will work if I login through a browser such as dolphin or firefox, but not through the official facebook app itself. Same with twitter.
My max MTU is set to 1492 - i've checked this is correct using the instructions you provided and it is...
Another issue is browsing the internet - sometimes if i open more than one tab, it stops working altogether, and subsequently any other app that requires access to the internet will not work also. The only way to resolve this issue is by turning the phone off and back on again.
Really struggling with this. Could it be as simple as switching channels within the router?
Im open to suggestions so any ideas i'd appreciate!
Thanks again,
Luke.
Dear Luke,
Ok.. Thanks for the input.. See, if your facebook and twitter is working fine on other Wifi's, it means that there is no problem with your phone setup.. also, when you are using on 3G, there is no problem and that confirms that your handset has no problem at all.. so dont worry on that count..
Read my post carefully..
I had suggested you try upload a pic on facebook using wifi (the one which has problem).. If you are not able to upload, that should confirm that your home wifi has to be set up properly. There are two types of installations of Wifi.. (1) in which the Broadband Modem and Wifi is in a single device and (2) where you have a broadband modem and then a seperate wifi device.
Now the broadband modem also has its seperate MTU which it uses to interact with the broadband server.
Similarlt, the wifi decive connected to the Broadband modem also requires its own MTU to communicate with the broadband modem..
These two are therefore different settings.
You dont typically have to change the settings on the Modem, but only the wifi device. When I faced a similar issue, I had to check and reduce it to 1430 myself so that it works properly.. Try the same.. Try reducing wifi MTU to 1430 leaving the modem MTU to 1500 (default). If you do it right, you will solve the problem...
I had exactly the same problem but I found no real help on the internet android forums.. But that history..
Now, I know this is the real problem and the cure is easy... "Just set the MTU on wifi (device) to 1430... DONE.
Try rebooting the router, and then flush dns settings in cmd.

Hi again,
Allow me to give you a bit more info...
I'm on a talktalk (rubbish!) landline/internet package. My netgear router is plugged directly into the phone line via an adsl cable. The router is configured for wifi access. I presume as I have no seperate device, that the modem is built into the router also.
I tried uploading a picture to facebook and it failed after a few minutes of trying.
Basically last night I tested the MTU via the command line interface using the ping command you provided. At 1464 i no longer received the fragmented packet errors, so i presumed adding 28 to 1464=1492 was the correct thing to do, and so I did this and then checked that in the WAN settings in the router config the MTU value was set to this which it already was.
I'm not quite sure how I set the MTU value specific to the modem if doing so under the WAN settings has not already applied it for both wifi and the modem. Can you provide further assistance if I should be changing a setting elsewhere?
Some further info - I have changed my router so it does not broadcast the SSID, and so that you can only connect to it if your MAC address is listed under the allowed devices which my phone is. I'm not sure if this would cause a problem - it never with the iPh*** (he who should not be named!) i had previously!

Hi,
I had never thought of doing this but will give it a go tonight.
Thanks,
Luke.

Its probably not the answer, but its one of those silly things...and the worst it can do is just freshen the connection.
EDIT:I messed up the previous link. so here it is: http://www.tech-faq.com/how-to-flush-dns.html
Just set it to 1464 then. We are on the right track.

Hello all,
I've had my Nexus 10 since Christmas and it's never given me any problems. Within the last 3 or 4 days, however, I noticed my videos weren't loading like normal, so I've been running speedtests and it is completely inconsistent. My phone and computer will consistently pull 20+ Mbps, but the N10 is crazy. Sometimes it's 3Mbps, sometimes it's 10Mbps, sometimes it's 16Mbps. Every time I check, it's different. I've used multiple programs and websites to read the speeds, and they're all reporting the same. I can stand in another room, or right next to the router, same story. The wifi never fully drops, it just slows way down. I don't have a case on it. I've turned on and off the Wi-Fi optimization in settings. I've turned on and off location settings. Nothing helps! Please let me know if you have any ideas. I am hoping I won't have to return the darn thing, it seems crazy.
As per my internet, it's Comcast, Surfboard modem with a Linksys E1000 (Wireless-N, 2.4GHz) using WPA. Restarting that did not help. I am open to the idea of changing some settings on the router however, if that might be a solution. Also, signal strength on the N10 says "Excellent" and link speed says 130Mbps.
Thanks for your help!

I too have this problem so now Im going to attempt to root the device
Glad to hear someone else is having similar problems.
Possible good news: I changed my protection from WPA(mixed) to WPA2, and so far things seem to be much more consistent. This may just be a fluke, but it's looking much better so far.
If you have a router with 2.4GHz band only, try changing it to 2.4GHz under WiFi settings on the Nexus.
I had some disconnection problems due to that and somewhat inconsistent speeds, I've seen it fix a lot of peoples problems, I've yet to have a transfer problem so far with limiting WiFi to the speed of my router.
Other issues some see is using N wide or dual channel (40Mhz). As the N10 only supports 20 Mhz in 2.4GHz it seems to get confused.
Most other devices either support 40GHz or handle switching more gracefully.
In short force router to 20 Mhz/single channel, may report more consistent behaviour.
On 5Ghz it does not matter as the N10 supports 40Mhz/Dual channel.
Odd, I know.
My experience is that sometimes with wifi issues, wiping the cache (if custom recovery is available) would resolve the issues for some time, but it might be due to an beta ROM.
P.S> on 5GHz wifi I am able to hit 122Mb/s
it has WIFI, mine hardly works
After a few hours of testing, I am now consistently getting 20mbps + as I should be. My router is set to 20MHz only, but I think the main issue was the security settings. It just wasn't dealing with WPA(mixed) well.
