[Q] Wifi Problem

Guys, my wifi is acting really really weird lately.
I flashed aokp m4 with franco r98, and it works perfectly with my home wifi. But at school, it would not connect even though in wifi settings the phone can see the wifi and its full bars. I stood next to a friend with a gnex unrooted and stock Rogers rom, and he has full bars. While on my phone, it just says that the network is saved. I have been able to access the wifi before back when I had stock. So I decided to try my cwm backup of my stock rooted and still no use. wont connect.
Last try i made was to reflash google 4.0.2 stock image and lock bootloader, and try it with the factory rom. NOPE, no help at all..
Right now, Im back home on my wifi, full bars, and no problems watsoever running m2 with r98 again. but still...why???!!!
Is it hardware issue? How can I test and check!!! i really need this solved...as wifi is like a necessity in life these days LOL
Also, I tried foxhound before i went to stock, and still wont connect to school wifi.
One more thing, there is like one spot to two in school that i would get 1 tiny dot of wifi, whereas every other phone around me including the ipods have full bars...SOooo, any fixes?

anyone help ？

Before you flashed your custom rom did it work at school?
If it works at home, then it probably isn't a hardware issue... maybe check your wifi settings and try putting the frequency at 2.5 Ghz instead of auto? Or try to put it at 5.0 Ghz?
Maybe there are some Wi-Fi apps you can try searching for in the market that gives you more information?
You sure you're typing the correct password?

I'm not exactly sure about the wifi diagnostics app, I just got my phone a couple days ago
I'd say just download some random one's for now. See if the signal that it's reporting is different. Maybe long press the network name and select "forget", then try again?
Are you not getting enough bars? Or can you just can't connect to the AP?

Authentication problem (wifi) after AOKP + Franco's Kernel

Hi there
I keep on getting the message of "authentication problem" whenever I try to connect to my router.
It all started happening after flashing AOKP + Franco's Kernel.
I today reflashed for the second time both (Over CWF) and the problem persists.
A few hours ago it was all good on stock 4.0.2.
I have a GSM Galaxy Nexus.
Any ideas?
I have no Mac address filtering and I have re-entered the password million times. All other computers and phones are connecting.
Any help would be really appreciated.

Anyone? Please??

I am not sure if I am having the same issue, but my wireless drops out each time I connect to a different access point
my bad, it was a setting in unlock with wifi that was turning wifi off

That used to happen to me with stock rom 4.0.2. Very annoying thing.
I just fixed my issue with Franco's kernel. I flashed one of those kernels that get updated nightly and now it connects to my router. I guess it has nothing to do with the other kernel but yeah, who knows.
You should flash Franco's 4.0.3 and AOKP. The speed improvement is crazy. Before it was so laggy with stock 4.0.2, even stalling sometimes. Now I can almost compare it with the speed of an iPhone 4s that I have here.
AOKP did an insane work. I'm definitely going to donate. And to Franco's too. They should be doing Samsung's work!

Signal Drops on Wind Mobile

Hi guys,
I'm on Wind mobile in Canada (london), running AOKP 32 with franco kernal milestone 2. I've been noticing that my nexus completely drops signal once or twice a day and then picks it back up after a couple of seconds, while I'm using it. I just bought the phone about a week ago and was quick to put on 4.0.4. I've also tried the ugla4, uglc1, xxla2 modems with the issue persisting. I'm really hoping this is a software issue related to 4.0.4. Is anyone else having the problem?

That was the first thing I tried! I'm still surprised it didn't work.

Roman himself has signal drop issues with AKOP ... i haven't had a single issue on CM9 where i have on different roms ... i'm using UGCL1 radio on Rogers and in London as well

Try setting your min CPU to 700

disabling smart reflex is usually a better option then increasing the min clock speed as that will decrease battery life. Fugumod kernel has smartreflex disabled.
I have been having this issue, although since flashing AOKP B32 and stock kernel I have not been having that issue. I wonder if he changed something in the last build. Also using UGLC1 radio.

I switched to CM9 after you suggested it might be an issue with AOKP. It's a little early to tell, but I've been using CM9 for about 2 days without any issues. It looks AOKP may have been the culprit after all.

[Q] Slow wifi on CM9

Yesterday, i have unlocked and rooted my phone to put CM9 nightly on my galaxy nexus[GSM]. Everything works fine but i have one issue, the wifi speed is really slow on my phone.
this is the rom that i flashed on my phone.
http://forum.xda-developers.com/showthread.php?t=1398495
I have tested on speedtest.net and i am getting less than 0.5mpbs. I have looked over my router and other devices, they are getting 5mpbs. Is this an issue with CM9? On stock settings for the nexus i get 5mpbs.
Is there a fix around this?

What is your broadband connection rated at? 5/10/15/20...mbps? If you are rated at 15 or 20 and your only getting 5 on other devices you could have a router issues.
Does the speed get any better when you are within 5 feet of the router?
Do you have multiple Wireless Routers/AP's?

there is no difference if i am beside or 20 feets away from it. I still get less than 0.5 mpbs. There was no issue when i was using the stock version of GNexus 4.0.2.
I only have one router.
I have managed to fix the problem, can a mod please delete this thread?

I have the same problem. When I restore back to stock, the problem goes away. I do have the FD01 radio firmware installed.

How did you fix it? You could at least share it with all the people who tried to help

Hi folks
I was having the same problems. I just upgraded to 9-20120511-NIGHTLY-maguro and my wifi issues have gone.

Try rebooting your router. I've been using CM9 for weeks now and the only time I've had issues were with my router.
This isn't even the fastest.. just a random test. CM9 Nightly 5/11.

I have the same problem after I assigned my phone a static IP on my home router. Search on MAC randomization for this issue. There are several kernels that fix this. I believe Franco, Trinity, and Imoseyon will work. I wish the stock cm9 kernels would get fixed for this issue.
Sprint GN, Tapatalk

Do you have some sort of QoS setting on your router keeping it from providing the speed to certain devices or something like that? I agree with the others, first thing I would do is factory reset my router.

Having a similar issue my epic is doing 25mbps on a 30mb line but both of my gnexs on different roms are only getting g 10-12????

I've also noticed that my Wifi performance is seriously degraded and very slow. At first I thought it was my connection, but further testing narrowed the issue to my Gnex only. I get very long 1000+ms ping times using the speedtest app and get a stuttery 1-2mb/s down and up, when every other device in my house (6+) is showing upwards of 20mb/s down and 2mb/s up. I have replicated the horrible ping and download times from various wifi hotspots.
To test further, I reverted to a backup nightly with no change. I went back as far as my 04/29 build and the problem remained. Maybe I just didn't notice it before, but I'm not certain. I have even flashed other ROMs such as AOKP and speedtest showed superfast results.

Wonder what AOKP did to it because myself and many others finds wifi to suck on the stock roms.

The wifi problem goes away when i use a kernel that addresses MAC randomization.

Figured out the cause of the slow wifi
I found out what the issue was with my wifi slowness and awful ping times.
I re-installed the latest Nightly and this time I did a "wipe data" (wiping out all of my apps) and my speedtest results were awesome again. Essentially a clean install. After reinstalling my apps one by one, I've been running speedtest each time and found that Doubletwist/Airsync was the cause of my slowness. Uninstalling DoubleTwist/AirSync and then rebooting fixed the speed/ping issue right away. HTH.

You could also try AirDroid (https://play.google.com/store/apps/details?id=com.sand.airdroid) as an alternative to upload/download files to your phone.
Works great for me ^_^

AOKP WiFi Issue ATT 9/5 ??

Has anyone had issues with WiFi not picking up? I have three phones one skyrocket and two art s3 running all different builds and none will connect to WiFi they see the WiFi but won't obtain IP even if I disable data packets. The s3's are running KT kernel so thinking maybe keep that off and reflash?

if all 3 of your phones are not connecting, it only makes me think its an issue with your router.

Agree. Test the phones on other networks, and bring another device to the network you're having issues with to verify. If three different wi-fi enabled devices are having trouble connecting, it's probably the router. This is what I do at work all day >_<

Your right it was the router it supports WPS but the handshake was not compatible 802.11n+m I changed the router to 801.11b it works on all of the phones. I seen other issues regarding this on various threads it may be a default setting via one of the kernels the 802.11b mixed with something else or that it does not auto detect as I did assume.
My bad, jumped the gun due to other posts related to AOSP and AOKP builds after 4.0.4.
Thanks,
JK

Thats not really true .. I experienced the same issue in regards to my S3 running anything that was AOKP/CM10 etc etc .. I started a thread about my issue under the Q&A section in which we found a resolution .. and it had nothing to do with a+b+g+n !!!
I have a LinkSys E4200 router .. on stock/leak builds, my phone connected instantly .. anytime I flashed AOKP, CM10 variations .. my phone saw the router, saw the SSID's .. but refused to connect via DHCP .. it would connect however by static !! This was driving a few people nuts .. and for some real strange reason, it had to do with the naming of the SSID that was causing the problem !!
My old SSID was "lordgeek_24" and "lordgeek_5" .. for both the 2.4GHz and 5GHz bands .. everything set to mixed connectivity. All I did was renamed my SSID's to "LordG33K24" and "LordG33K5" .. kept everything else the same (WPA2) .. and WHAMMM .. my phone connected instantly .. I'm running the Nightly CM10 .. since renaming my SSID's .. NO PROBLEMS :victory:

And my and a few others issue is slow download speeds on wifi.

I have really bad download speeds on AOKP Task and Ktoonsez and running KT kernel. I do not have LTE yet but H+ is faster than my WiFi which is 5Gbit/sec. I can only get about 1550 of 5 whereas my girlfriend gets 5 on her Atrix I've searched for hours for an answer and this thread is what I've finally found. Can anyone help me fix this before I go to the ROM or kernel thread? Thanks.

No just this router. Its a Net gear WNR2000. I updated the firmware and have reset the modem and still only half the data speed I should be getting. I am going to change the SSID and change channels when I get home and check the results. Any other suggestions I should try?
