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):
[HKLM\Comm\TIACXWLN1\Params]
"dot11SupportedRateMaskG"=dword:00000008

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

Right now I am getting connection speeds through WiFi between 650kbps and 1200 kbps according to www.2wire.com speed test.

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?
I've noticed the following problem:
When trying to download (file copy/video play) from my LAN to the HD, download speeds maximum is about 340 kbps (LOL...that's like EDGE) . With the same setup (wireless "G" router) I can download on the HD from internet with speeds 2 000+ kbps. LAN operations between my PCs/laptops are @ 60 000 kbps wired and 20 000 kbps wireless (using the same setup). To access my LAN from the HD I'm using Resco Explorer....and at that 340 kbps speed it's not possible to watch movies from my LAN. No such problem with my other PDA (iPAQ HX4700) which is not even "G" but "B" device - speed is about 3 000 kbps. Can anyone confirm this and suggest a solution? Can anyone watch movies from LAN encoded with more than 400 kbps?
p.s.: Speeds are measured using DU Meter (for PC)
p.s. 2: Same low (340 kbps) speed with another wireless router

if you are using the default memory card that came with the phone, it is only a class 2. the write speed isn't spectacular, this may not be the reason. but it's the only variable i see right now. since your can download stuff to your phone from web at good speeds. i think it's more of a problem with the machine that is "uploading" or hosting the video. check the upload speed of that machine.
I think the memory has nothing to do with the problem. And I've tried with different host machines - the same result.
Slow network speed through WIFI
I have to same problems on my HD. I am using a home server at home which holds all of my videos. When connecting to it and watching a video with my old Eten X800 everything works fine and runs smoothly. But doing the same on my HD results in an unwatchable video. If I copy and paste this video on my mem card on the HD the video runs smoothly. There are some strange things going on with the WIFI speeds on the HD
Anyone worth investigating this issue?
Yeah... the strange thing is LAN speed is much lower than Internet speed using same network equipment

These settings affect both Internet and LAN performances but Internet speed is OK and LAN speed is slow. And yes, I did play with the settings - results are the same. (because I'm 2-3 meters away from the wireless router). I'll be glad if someone with HD, actually tests a connection between his HD and a PC in a LAN and not just giving "blind" suggestions. What I want to know is if it's a problem with all HDs or just my device is faulty.

the nerd in me just want to go to your house and troubleshoot this for you in person. LOL... anyway...
what is the file you used to test in each case? the reason i'm asking is that some files are more compressed than others, and the speed we see is the NOT the raw speed -- the capability of the wifi card. but the combined speed of the CPU processing power and the network speed.
long story short, if you are downloading, the data is broken up and transfered piece by piece -- a movie is broken up and transfered bit by bit. depending on the file, the receiver side needs to process these bits and recombine them back together. it's much easyer to recombine a webpage, text file or equivalent. but mp3s, rar/zip or movies are already compressed/encoded with special algorithm, so the receiver processor needs to chew through these data to recombine them, so it won't accept faster than it can "chew".
of course this may not be the reason for your problem at all, but try transferring a large text file (copy and paste text from a website to notepad and c+p over and over, till you have a ~ 10MB txt file).
Even on copy files (not trying to play them, hence no decompression) just copy from PC to HD, no matter what the file type is, the speed is that - 340 kbps. Why don't you just try it yourself?

With my HD the same slow speeds. Tried several different hardware. Only HD is slow as hell. WIFI speed tweak does'nt do much, btw.
Some speed results:
WIFI Setting Best Battery / Resco Explorer 7.05: 45 KB/s
WIFI Setting Best Performance / Resco Explorer 7.05: 300 KB/s
WIFI Setting Best Performance / Total Commander/CE v2.51: 600 KB/s
So Resco does not work well with local shares. won't be using that anymore when c/p'ing. Altough speeds are doubling with TC it still is'nt fast imho.
Noone else tried this and encountered the same problem?
Ever find a fix for this?
I noticed the exact same problem last night when trying to play some TV shows over Wi-Fi from my PC. The file played OK for a couple seconds, then stalled
Using "Network Plugin for File Explorer" from HTC, I get an ave. speed of ±340kbps. The speed is the same whether I save to memery MC or phone memory. So the write speed of the MC has no bearing on the problem.
PS. Just tried on my work network with the same results...
Lucky you guys... I at best performance get ~120kb transfer and at optimal I get ~80kb transfer (copy) with Resco on wrt54gl with ddwrt on it
Is it just me or are WiFi speeds on these tablets very slow? If anyone know Of a fix it would be appreciated.

I've seen other posts where people have found a small gap in the shell resulting in poor contact inside for the wifi leads. Some were able to squeeze the shell tighter to help and some opened the back and tried to carefully adjust the pins to make better contact. At least one person broke a contact pin, so be careful if you try that. My wi-fi connection and speeds are very good.
I can download a 100 Mb file in less than a minute, and web pages take less that 3 second to load.
Though, I have a 30 Mb/s connection from Charter that I can constantly get up to 45 for some reason.
Last night I transferred GBytes of data via ADB (i did a full tablet wipe and a bunch of restores) and couldn't help but notice that sustained data transfer via (wired) ADB is only about 1.4 Mbytes/sec. Sort of pathetic waiting around for a half-hour to transfer a 2.5 GB file.
Anyway, not to jack the OP (which is about WiFi), but I wanted to try and figure out what my best options are for high-speed backup (I have a 32 GB N7!) - including WiFi as an option.
Ran a couple of file transfer trials this morning using a ROM file that was 150,137,068 bytes.
Results first, more detail on each setup follows. (The results are compared in terms of data payload per second; in the cases where protocol overhead is high, the wire-speeds would be higher than calculated)
[1] SMB/CIFS write via WiFi : 518sec => 2.32 Mbits/sec. UGH (best of three trials)
[2] FTP put via WiFi : 109sec => 11.06 Mbits/sec
[3] FTP get via WiFi : 121sec => 9.9 Mbits/sec
[4] adb pull via USB : 78sec => 15.4 Mbits/sec
[5] adb push via USB : 117sec => 10.3 Mbits/sec
[6]* OTG VFAT write via USB: 33sec => 36.4 Mbits/sec
[7]* MTP copy via USB 13sec => 92.4 Mbits/sec
In the WiFi cases:
- Linksys WRT54G (802.11g) router circa 2006 [ 802.11g theoretical bw 54 Mbps ] 6' away -35 dBm signal
- SMB/CIFS "server" Windows Xp SP3 laptop on 100 Mbps Ethernet segment attached to router
- N7 SMB client app ES File Manager
- FTP Server app (Andreas Liebig) on N7
- FTP client app Windows Xp default ftp app for both push and pull
- Windows box on Ethernet, N7 only on WiFi.
In the OTG case:
- 8 GB Sandisk Class 2 microSD card on a card reader attached to OTG cable; single partition, empty card, VFAT formatting.
In the ADB case:
- adb v 1.0.31, Win 7 Pro x64, Quad-Core i5, USB 2.0
Observing the WinXp task manager performance tab during CIFS or FTP transfers, the wired (Ethernet) link would show a high degree of variability, oscillating between 5 Mbps to 15 Mbps instantaneous rates. Hard to say whether this is a router performance issue or something else (11 Mbits/sec approaches 1000 pkts/sec at a MTU of 1500 bytes).
* The numbers for the OTG and MTP transfer tests are possibly questionable as the role of file caching is unknown - the times given here are only the times that the file transfer dialog(s) remain on-screen. (The writes could be completing in the background out of cache with nothing showing on the screen) In particular, note that the OTG copy involved a "Class 2" microSD card - and yet the write speed seemed closer to 4.5 Mbytes/sec, rather than 2 Mbytes/sec
The SMB/CIFS transfer times are quite pathetic; but as with all performance measurements, any participant in the test could be the long pole in the tent. For instance, the issue might be the ES File Manager app. I did not test with a N7 CIFS-capable kernel.
Also, it would also appear that performance of ADB for file transfers are quite poor - well, in comparison to MTP anyway. Too bad MTP doesn't preserve file timestamps (as well as all sorts of other oddities).
Apologies in advance for using file transfer as a network benchmarking method - my connection to the outside world (DSL) peaks at only 3.8 Mbits/second, so I would need to set up some kind of LAN server to benchmark network performance in absence of flash-memory or hard-drive writes.
Anybody have any performance numbers to share for:
- OTG mounts of hard drives or SSD devices with NTFS or ext4 file systems
- CIFS/SMB network mounts with CIFS-capable kernels
- WiFi speed tests when remote server is via FiOS or U-Verse fiber connection?
========================================================================
[Edit] -- Added some network-only test results.
FWIW, I ran a couple of tests using the "netcat" tool to evaluate the same setup without writing files to mass storage devices. It turned out that a terminal emulator app that I have has a busybox with netcat built in, so I booted the WinXp laptop into a Ubuntu Live CD (10.04LTS), and ran netcat TCP write tests in both directions. I also used "iptraf" to look at peak bit rates.
Result? Peak observed speeds were about 16.6 Mbits/second, and sustained-average results were in the 11-12 Mbit/second range. From that I conclude that that the FTP transfer tests were probably network-limited, as testing involving file writes were really no slower than this. Whether that means the "N7 is WiFi limited" or something else is not deducible from the data I collected. In this case, it takes three to tango (N7 - router - laptop).
I do note however that blahman179 said above "100 MB in less than a minute" - 100 MB in 60 seconds is about 14 Mbits/second. Only a little faster than what I observed - right in the same neighborhood.
Note that I had my WiFi router set to G-only. I suppose that the basic bit rate with huge signals in the -30 dBm range means that the radios are indeed transferring packets at a 54 Mbit/sec bit rate - but with a duty factor of less than 30%.
@OP:
fwiw, I did a little searching. Some XDA N7 users with high speed ISP connections report peak download rates of 20-30 Mbps when connected to networks that can do much better than this using PCs.
That "speedtest.net" app reports peak values recorded over short intervals - I suppose that sustained (average) transfer rates are somewhat worse than this.

Also Comcast and probably others boost your speed for the first part of your download making burst speeds optimistic.

Having trouble with all wifi connections on my nexus 7... When i am on my home wifi I get 5mbps where all other g connected devices pull 25mbps. That's not so much of a problem. When I am tethered to my cellphone via wifi I get 600kbps with the nexus 7, but my cellphone tethered via wifi to my pc is 4mbps. I'm concluding something is wrong with the link speed on my nexus 7 but don't know what to do about it. Any help would be appreciated cause I really need more then 600kbps when not at home, especially when my phone regularly pulls 10mbps in my area.
I agree with the WiFi connection being slow with the n7.IMho I've seen better download speeds with my galaxy tab 2. I've also noticed with certain kernels the WiFi is faster.stock to me is the best and now I'm running the faux kernel and it ain't too bad.
I just tried the speedtest.net app and averaged about 9.4Mbs down and .68 up. Stock rom, rooted JB.
Hi
While at work I connect to the wifi because my connection isnt the best, It says I have a good connection (up to 86 MBPS) but its super slow. I ran a speed test and my DL speed was .96 and my up was 5.67 MBPS. My friend is connected to the same wifi but on a S5 and got 10.76 mbps on DL and 30.5 UL. Ive tried clearing the cache in recovery and even forgetting the network and reconnecting, any other suggestions?

download " dnset" https://play.google.com/store/apps/details?id=com.dnset&hl=en, let me know if that does the trick
For some unknown reason Samsung use BIC as the TCP congestion Algorithm. Its reliable and good for high latency networks, but its pretty slow.
As far as I know you can only change it (to something better like Westwood) by rooting.
I tried using the DSNET and it didnt do anything at all, the speeds remained about the same and in some cases slower. I would like to root to my pohone but I might get my phone replaced first by T mobile

That is for changing DNS, has nothing to do with the problem OP has posted, the change in TCP Congestion maybe could work if there is not an error in the drivers.
Try to download Kernel Adiutor and in Misc. Controls change it to cubic or westwood and test the speed.
To do a reliable test, you should use iperf and not other application, he.net - Network Tools has iperf v2 and v3

That is not the way to go if the drivers are correct, now wifi will drain power disabling power saving mode

hmm well seems to speed up mine and i have no power drain. It went from ac to wireless N

So if you moved from AC to N is not a speedup because of N standard has lower rates, mine is connected in AC and I'm getting speeds between 270Mbit/s and 316Mbits/s, this is using channel bandwidth 80Mhz (in N you have no more than 40Mhz).
If you want to do real test of bandwidth, use iperf v2, for PC you can download here:
http://sourceforge.net/projects/iperf2/?source=typ_redirect
For Android download Aruba Utilities and use Iperf with that
Usage:
iperf -c X.X.X.X (x.x.x.x is the ip of the iperf receiver)
iperf -s (server mode)
Do it in both directions, PC server and Android in server mode and compare changing N to AC in the router.
I have discovered that my US996 Unlocked and rooted device has typical down/up speeds of 90d/55u when the phone is not being charged. When the phone is connected to a charger the typical speeds are 400d/270u. This is very repeatable. The phone is 3 feet from the router. am using speed.net and the ping is 4 to 5 ms for both configurations. If I start the test with no charger and plug the charger in during the test the speed increases dramatically to the higher values. The verizon.net speed test for the router on my gigabit plan was fairly consistent at 948d and 931u. Is there a way to get the higher WiFi throughput while not connected to a charger?
Which router are you using btw ?
90 Mbs down seems like single stream N, on 2.4Ghz
400 Mbs down is single stream AC at 5Ghz
Can you check what your link speed says in the wifi props on the phone
the single sim V20 is dual stream so you'd expect a doubling of that speed, should be able to do 800Mbs on AC and 180 Mbs on N at 2.4ghz with a dual stream router which most are these days.
The dual sim V20 is unfortunately single stream so my max speeds are 90 & 400Mbs instead of being twice as much
I don't understand why you get a difference in speed in the first place. Should not matter plugged or not
I'm using the Vz provided G1100 gateway router. Link speed on the phone says 866 Mbps. I'm at a loss too - probably a phone hardware problem. BTW, I'm still on US99610d deodexed ROM with Xposed and other mods that I wouldn't THINK would cause the problem, but....

Bolded bit implies your connection is good. Dual AC which i was expecting.
It's possible LG ramp down speeds to conserve battery. Not an issue with general use only with downloading
Bolded bit? Sorry, but I don't know what bit you are talking about. I remember seeing nothing bolded in anything wifi (settings). My router lists my V20 connection as "802.11ac" and I see nothing indicating any problem. But the phone still has the problem. I'm wondering if there could be an antenna problem and the charger conection acts as an extra antenna? Obviously l'm groping in the dark now.
