[Q] WiFI Problems Even After New Kernel - Verizon Samsung Galaxy S III

Hello!
I have had terrible WiFi signal no matter what router I use for a very long time. Today I just flashed the fully stock JB image from Odin, then rooted and unlocked my bootloader to flash the 747 kernel because it said it had WiFI driver updates, but I still get terrible signal. I can barely use my WiFi at my house, my school, and at work. I know that there are known issues with the WiFi but I figured after the JB update or at least a new kernel with updated drivers, that it would be fixed.
The issue is not only that if it connects, it disconnects, but the reason it disconnects is because the signal is so weak (at least according to my phone). Most of the time I can't even see the WiFi networks but I had someone with a Galaxy S3 right next to me and they had perfect WiFi signal while I couldn't connect, so I am completely lost at what to do next.
Any help would be much appreciated

[Baseband test]

I had problems with my bluetooth and worse signal on both wifi and phone after using leaked baseband.
My bluetooth devices got disconnected 5-10 times a day on leaked baseband. My 3g froze a couple of times and and wifi was really weak.
I then tried official baseband, didn't change anything else in the ROM i was using. Not a single disconnect during 48 hours, wifi was stronger and 3g worked like a charm.
To be sure i flashed leaked baseband again and the problems was there again.
Flashed back official once more and all is fine. I think the battery time has improved as well but this can be placebo.
What bothered me most was the bluetooth disconnecting. As i said, all is fine with official baseband.
Hope this helps someone.

Sensation XE ICS WiFi/3G data issues

I've S-OFF'ed my Sensation XE and have installed ICS as per thread:
http://forum.xda-developers.com/showthread.php?t=1538032
So this is the official ROM I've installed:
OTA_PYRAMID_LE_ICS_35_S_HTC_Europe_3.32.401.105-1.73.401.4_P_release_246589q3t6rh79ci68p68k.zip
All flashed OK, but my WiFi is very unreliable.... 3G isn't that reliable either.. seem to have to reboot the phone to get it working every day or so.
I have tried resetting the phone, but still the same.. thinkiing about going back to Gingerbread...
Anyone else having similar issues?
Thanks
I'm not using the official ROM but ARHD which is based on stock.
I haven't had problems with 3G and WiFi (apart from it turning on randomly).
Does your WiFi and 3G turn off and not reconnect?
ive been having mobile data connection problems with pretty much every ics rom ive tried. its confused/frustrated me as no one will will address the issue or offer any possible solutions. only fix ive found is going to phone info and turning radio off then on, also try resetting apns to default.
@cory0821 : Exactly the same issue.. turning data on and off (either wifi radio or enable/disable mobile data) seems to 'usually' fix the issue, other times it just doesn't work until I reboot.
The other issue I have is that if I leave the WiFi on when it's 'sleeping' - it kills that battery. i.e. WiFi consume 30-40% of battery within 10 hrs.
And if I go into the advanced setting to turn off WiFi when sleeping - it makes the above data issue much worse.
I am very happy with ICS on the Sensation XE in terms of smoothness and functionality, apart from I no longer have working data... I think my next question is how to I get back to Gingerbread at it's not really workable at the moment as a Smartphone.
I'm glad it's not just me as HTC might fix it, but surprised that more people are not having the same issue.
WiFi doesn't turn off... it connects to my home WiFi without any issue (and at work), but even though it's connected, none of the apps seem to be able to send or receive data.
I had the same problem with Wi-Fi after flashing ICS. After asking many times in several threads I finally learned that if you are with T-Mobile ICS will not support Wi-Fi. I don't know the technical details, but I was told T-Mobile had to release an official "T-Mobile" ICS before Wi-Fi would work correctly. No one seems to know when the official version will be released.
I am running coredroid v5 ICS and wifi and wifi calling are now working with tmobile. There are some times that wifi calling is not working 100%, but the wifi network for market, e-mails etc. is working great.

WIFI and mobile data handoff?

No ones addressed this. When turning on WiFi and WiFi calling it kills radio and can't be fixed until a reboot. Anyone have this. Also WiFi calling on this thing is horrible, and reception. Want to like this phone but probably getting a gs 2.
I have no wifi calling issues, at all.
So if you turn off wifi calling cell does not come back?
If wifi calling is on it should turn off the radio.
That is normal for wifi calling on the newer software phones. Even my Amaze with ICS does that too.
If you also have wifi calling set to WiFi only it will not get signal back properly until it is rebooted or in range of good enough wifi signal to re-enable.
I'm not seeing this either. wifi calling works fine for me and I haven't seen any problems with the handoff when I go out of range.
What ROM are you running? I'm using stock 1.53
It gets stuck trying to reenable mobile connection and I have to reboot

That is odd. For my phone it takes a few seconds to switch from wireless calling to regular cell signal when I turn off WiFi. If you toggle airplane mode on and then off, does your radio work? If not, check to see if your phone has the latest update for it already (under settings->about->software updates, I think). If that doesn't work, I don't know what else to try. You might have a defective unit. (edit: if you haven't rooted it and modified it)
Wireless calling does suck for this phone. I kill my wireless connection when a call drops and call back under good ol' cell reception. Heck, I can't even call voicemail under WiFi calling since the pass code dials don't go through properly. Then again, this is what you're trying to resolve, getting reception after disabling WiFi, so this workaround is not yet possible...
In response to the call quality, I do notice lots of "pops and clicks" in the audio when using wi-fi calling. I have seached the forums and this seems to be a pretty common issue with this phone. I've noticed it on Skype too, which was also a reported issue. Seems there are some bugs to workout on this phone, not too worried about it as its a new phone. Im sure some roms will fix these issues, if there isnt one out there that already does.
I'm using the latest TrickDroid ROM and I've noticed that sometimes the phone does not connect to data when I leave wireless. The wireless call quality is hilariously bad.

Terrible WiFi performance. Anybody having the same issues?

Started having this issue from a week or so. Its so terrible can't even stream a single YouTube video without network connection issues. I have a xiaomi mi3 connected to the same network and it can perform without any issues. First screenshot is from xiaomi mi3 and the second from opo. Does anyone have the same issue with their opo. Please let me know if their is a way to fix this. Opo is running stock cm 11s version xnph44s.
Maybe you have apps that slow down your WiFi Connection. Are you rooted or have you made any changes on your system? A Factory Reset should fix the problem.
Thanks for the reply. I am running stock cm 11s. Didn't root or not running any mods. Its bare stock. I couldn't even have a good network connection for at least 5 mins straight. Play store downloads take forever. Thanks appreciate the help.
Yes, me too.
Worse connection "power" compared to my old Galaxy s2 and sometimes I have random disconnection...
And failed to mention that there is no problem at all with lte mobile network connection. My OPO stays connected to the WiFi network and signal strength is strong but can't get packets.

[Q] weak wifi signal on HTC ONE X

OK so iusing my limited intelligence, I managed to root and install Kitkat 4.4.4 rom onto phone (cyanogen).
Now even sitting next to the wifi router i get no more than 2 bars or signal(most usually one bar), if I go upstairs I get no signal at all. My old HTC desire Z works fine though, as does my galaxy tab and partners phone.
I tried the old renaming the phone trick to fix the wifi issues but all i get is "failed to rename device"
any ideas guys? I didnt notice wifi issues before updating rom (but i did only have it a day at the time)
thanks in advance

Have you tried connecting to a different network and seeing if you have connectivity issues with others as well?
Thanks
