I have just got a new broadband contract with O2, here in the UK.
I have a wireless Box IV (4 in roman numerals) which supports wireless N.
My phone is connecting to this wireless box at 65mbps. I had expected it to connect significantly faster, because wirelss N supports up to 300mbps.
Can anyone tell me what the fastest wifi N signal available on the phone is?
Thanks!
James
Mine is consistent @ 65Mbps also.
Never seen mine higher than 65 mbps.
Using an AP D-Link DAP 2553 (Wifi N 300 mbps max) at 2.4 GHz
As far as I know the fastest available Wireless N-chip on any phone is 65mbps. If what I've read is correct this is because phones only have 1 WiFi antenna and speeds higher than 65mbps requires multiple antennas (google "MIMO").
is the galaxy s 2 Draft-N or 5.0GHZ N ?
Thanks guys. Ok, it's good to know it's not a problem with something.

I don't understand your question, SGS2 is dual band (2.4GHz N and 5.0 GHz N).
N-draft is gone since a long time ago, the N-draft standard was approved so basically all units sold as N draft is also "pure" N. But support for 5 GHz is always optional.
65mbps also.
Hello all,
I'm not sure if this has been answered. If it's not in the proper forum, please move appropriately.
After updating from 4.2.2 to 4.3 (Stock android), my WiFi performance has gone down the tubes.
It was literally about 50mbps and it is now around 10mbps. The difference is night and day.
Anyone else seeing this?
Thanks,

Apparently,
Whatever they did, it only effects 5 GHz (802.11a/n) and not the 2.4 GHz (802.11b/g/n) bands.
Apparently I seem to have won the lottery because I don't use anything other than the 5 GHz band on my phone.
Just my luck,
Tried fresh install and update. Same result.
Phone flies with 2.4GHz wifi but throughput is about 15% on the 5GHz mode.

I am seeing the same thing. My DSL is 40Mbps down and I used to get 20-40ms pings but now when I run speed test on my N4 after 4.3, I now get 0.5-2Mbps and 100+ms pings. I tried a reboot and I still get the same thing. Might have to try a factory reset.

Not sure if we're experiencing the same problem. Do you have access to a 2.4/5GHz dual band router? If you have you tested speeds based on the different access points that correspond to the 2.4 and 5Ghz bands separately?
Here are my results:
5GHz: 11728 kbps down / 33493 kbps up
2.4GHz: 44368 kbps down / 63497 kbps up
Speeds are very consistently performing under 11mbps on 5GHz not sure what they changed here but it is safe to say that this is a kernel based change and not a baseband change. Hopefully this can be improved upon by our kernel devs.
Thanks,

Yes, I have an Asus RT-AC66U dual band router. I do notice a major slowdown on the 5 GHz but the 2.4GHz is decent. My ping is kind of high (100ms+) in both cases though. On one of my computers that is wired to the router I consistently get 20-30ms for a ping.
Here are results from a speed test this morning:
5GHz results are about 2.5Mbps down and 4Mbps up
2.4GHz results are about 20Mbps down and 4.5Mbps up
Looks like I will be sticking with 2.4GHz for a little while. Hope this can be resolved soon.
Thanks,
Joe
Thanks for the update and proving my theory.
If more people can join in and verify these results, we might bring it to the attention to the kernel devs, who might know where the problem lies. I am not so sure a kernel fix would be coming anytime soon from google.

I have an Asus RT-N66U and was having the same issues. I didn't think to change the bands but my wifi speeds were horrible, so much so that I just went back to CM 10.1.2 because I don't have issues on it. My wifi would be fast at first boot around 30 mbps but after time I would drop down to like 100 kbps. My nexus 7 (original) had no slow down whatsoever. I may try to switch the bands to 2.4 because I didn't think about that but I really don't want to wipe and reinstall android again at this point.
Well i can't even connect to 5ghz anymore...

That simply doesn't make sense.
Are you using Stock Android Kernel? I say kernel because WiFi accessibility/performance is based on the kernel. So if you are using the OTA update rom but then you flashed X-kernel, you need to bring that to the attention the kernel's developer.
Also, the other problem a lot of WiFi users experience is caused by the encryption method used while on WPA2 PSK.
The options are AES or TKIP. One of these won't work well with some phone's WiFi drivers and most of the time you can't pick and choose. If this is the case, try connecting to a router that has these options (OpenWrt firmware based routers gives you this option).
Hope this helps.

I'd like to point out that doing Internet speed tests to determine wifi speeds is a bit half baked.
To accurately measure your wifi throughput, you should be communicating with another device on your LAN.

I agree that it doesn't make sense, but let me give you the details. I am 100% stock non rooted. this 5ghz network was working perfectly until I upgraded using adb sideload of the stock image. There is nothing else different. I have even tried disabling security to no avail.
I have this issue but its the opposite. 5ghz works well and the 2.4ghz is slow.
The same happens with my Nexus 10 as well. Just not as severe as a drop off.
Before 4.3 both devices had the same speeds on both bands.
I have the belkin AC1200db router.

I got the same issues as you. My performance on both 2.4 and 5 GHz is abysmal. I can barely even connect to the 5 GHz channel. Both channels are giving me 2-3 Mbps max. I never used to have these problems.

They're having the same problems.
Thing is, my new 2013 N7 runs flawlessly on the 5 GHz channel. 20 Mbps every time.

I agree about speedtests being done solely on the mobile phones are a moot point and half baked. However, I never implied that I rely solely on the data provided by my mobile phone. I have a couple of laptops and a desktop pc and all the devices (non-mobile phones) top out at the related 59 mbps speeds. My Nexus 4 always topped out at 50mpbs and I was really praising a device's ability to do so even in 20Mhz bandwidth (max data rates are 65mbps on the Nexus 4, meaning that i never connects at 802.11n speeds). However, post 4.3 upgrade (from 4.2.2 and also via a fresh install) left me questioning what went wrong with the 5 Ghz band. 2.4Ghz was working fine.

I can't say why this is happening on your nexus 4. It truly does bother me. Maybe something having to do with you method of upgrading to 4.3? Were you rooted before?
Also, the drivers are baked into the kernel. Nexus 4 and other devices will most likely use different drivers and hence the performance is bound to vary. My wife's Galaxy S3 doesn't come close to my Nexus 4 wifi speeds even though the S3 connects at 40Mhz bandwidth.

Again, different device, different Kernel and ultimately different wifi driver.
If I were you, I would also post my findings about your other devices on their appropriate forums.
Thanks,

Same problem. My router is only 2.4 GHz and it is set for G only. Before the upgrade to 4.3 I was consistently getting 20 Mbps average. After the upgrade to 4.3 I am now only getting 10 Mbps average. On the plus side, my data speed has increased 3 to 7 fold.
Having trouble as well. We have 75mb down with FIOS. We get that speed on our desktops and on our Nexus 10s. Our Nexus 4s, connected to the same exact router as the Nexus 10s, were getting 700 K down! I set wireless to 2.4Ghz only instead of Auto and was able to bump the speed to 14mb down. That at least is MUCH MUCH better, but it still annoys me I can't get our full speed on the phones. When I look at the wireless connection on Nexus 10 and Nexus 4, I see a big difference in reported link speed to the router. 130MB on the Nexus 10 and 24MB on the Nexus 4. I've pushed my understanding of the issue as far as I can. I'm stuck now - have no idea why there is such a huge difference.
Try different channels on your router. Some people are reporting success with that. Also, make sure your router firmware is up to date.

FYI, I've been experiencing the same problem on my Galaxy Nexus since updating to 4.3. My router is a Linksys EA4500 (one of the N900 models). It's a simultaneous dual band model. It's firmware is current. I have a different SSID for the 2.4 GHz band and the 5 GHz band. Wifi Analyzer shows absolutely no other nearby networks on the 5GHz band. The neighbors are only using 2.4 GHz.
The 2.4 GHz band has been fine for the most part; it's the 5 GHz that's giving me problems. For the 5 GHz band I've tried every combination of channel, width, wifi standard (N-only, A-only, auto). On some combination of settings I cannot connect to the 5 GHz band, even when it's found. With other combos, I can connect to 5 GHz, but speeds are a quarter to one half their usual. On rare occasions I'm able to get it up to normal fast speed, but then an hour later it's back to being slow again. Sometimes when the 5 GHz band is slow for a day or two, the 2.4 GHz band starts to slow down, too. On the phone I have turned off the wifi "always scanning" and "optimize" options.
Lately I've just kept the phone on 2.4 GHz only. I'm just about ready to force the phone back to 4.2.2.

I have started too experience the same problem on my Nexus 4 running 4.3. Everything was fine with 4.3 up until yesterday when I noticed my phone would no longer connect to 5GHz access points. I upgraded to 4.3 many weeks ago, so the issue did not begin right away.
I have seen this same problem on the Galaxy Nexus (multiple different ones) and the conclusion seemed to be some kind of hardware failure preventing the 5GHz wifi from working. Seeing the same issue reemerge on a completely different phone/platform is very concerning.
Let me ask you this, can you connect to your 5GHz wifi access point if your 1-5 meters away? I mean literately, stand next to the router and attempt to connect. I can get full speed 5GHz wifi this way on my Nexus 4 but walk away a few feet and the signal drops completely.

I've been searching for a while and i just cant seem to find the answer. I just upgraded from an AC 1200 to an AC 1900 router. My note 4's wifi link speed on the AC 1200 maxed out at 867 mb/s. on 5ghz which is the max for AC 1200.
Now with the new router it still only connects at 867mb/s and not the max link speed the new AC 1900 router should provide.
I know it dosent matter, has nothing to do with why i bought the router and is plenty fast enough... but it's bugging me.
I just want to know if the N4 tops out at 867mb/s? Has anyone gotten anything higher for a link speed?
thanks!!
I certainly haven't gotten anything higher than that with my RT-AC87 and my Note 4. Only topped out at 700-something Mbps while being in the same room as the router itself.
Usually, the bandwidth numbers on these routers are inflated for marketing reasons anyway. Sometimes they mash together the total theoretical bandwidth for the 2.4 GHz and 5 GHz bands, sometimes they assume you're using 3x3 clients (I'm pretty sure the Note 4 and most other smartphones and laptops are just 2x2), and sometimes they conveniently ignore the fact that Wi-Fi is an inherently half-duplex connection (transmit OR receive, not both, so your bandwidth's halved for bidirectional communication).
Your new router is probably only a dual band. Two channels of 433 Mbs. = 867Mbs. I have a Nighthawk Tri Band router which will combine 3 channels to allow 1.3Gbs. However I have no devices that support triband connections. My Surface Pro 3 and Samsung Tab S only connect at 867Mbs. Even the new Note 5 specs say Dual Band for the .AC radio spec. I haven't seen any new phones with a Triband spec yet.
Hi.
I am getting 50 to 70 Mbit/s wifi speed with my Le Pro 3 Al.
How come i can't get any faster wifi speed ?
And how fast wifi speed do you get in 2.4 and 5.2 Ghz with your Le Pro 3 ?
90.7 Mbps down and 10.6 Mbps up on my x722 on 5 GHz. Tested with the Amplifi app (for Amplifi routers only). But there are a lot of factors at play when it comes to Internet connectivity. Like the speed testing website or app you're using, as well as your proximity to your router.
My router is about 10 feet away from me. If my router was in the living room (I'm upstairs), I would be at around 30 to 50 Mbps down right now.
Also, add peak times for your ISP to the list of factors. My ISP (Rogers)'s peak times are in the evening. That's when everyone here is streaming Youtube and Netflix in HD. Some ISPs will throttle you during certain times too.
Another factor could be your Mediatek processor and your device's WiFi chipset. When it comes to wireless or LTE, Qualcomm has it down pat. I saw that the Pro3 AI does have MU-MiMO and two-stream WiFi like its Snapdragon counterparts, but I can't find any official specs on it.
Have you tested other Android devices on your WiFi connection? You'll know if it's just your device with those speeds then.
After extensive troubleshooting with my ISP's highest level tech support (I escalated my issue to the highest level) and ultimately swapping my Arris XB6 router/modem with a brand new one with a different chipset, my S6 Lite attains atrocious 2.4 GHz speeds.
Before people lecture me on how I should be using 5 GHz only, the fact is I usually can't because of physical limitations such as concrete walls, congestion, and and distance. What's interesting is how when connected to 5 GHz, speeds are fantastic and mirror other devices including my laptops, mobile devices such as iPhone/iPads, and even a wired ethernet connection to the desktop.
However, things quickly go to **** when using 2.4 GHz. I exchanged my S6 Lite and it's still doing the same. I tested it out in another area using a different AP with a different ISP using only 2.4 GHz and I got the same result.
When using other devices including new or legacy devices, they all kick the S6 Lite's butt in terms of speed. While I can often only achieve 6 -10 Mbps with the Lite, I get close to 70 Mbps on other devices and even with an old Nexus 7 2013 I get close to 40 Mbps, but not with the Samsung - connected to 2.4 GHz.
Using Wi-Fi spectrum analyzers signal strength and speeds are all awesome. I have a signal of around -37 dBm when on either 20 or 40 MHz channel bandwidth. I tend to get slightly faster speeds on my Lite via 20 instead of 40 Mhz. Channels are manually selected as Auto gives the worst possible speeds.
As such, I have come to accept this is Wi-Fi is an issue with the Lite and an not a defect per se. It's engineered this way. My question is though, how and why? Does Samsung use two different radios or "network" cards on the motherboard? And if anything, shouldn't the 5 GHz spectrum suffer before the 2.4 GHz? From past experience using Android TV Boxes, my issues have always typically been when connected to 5 GHz.
