Can custom rom damage my wifi? - Galaxy S III Q&A, Help & Troubleshooting

Hello, i've rooted my phone and installed black bean rom, and after while i've detected that my wifi doesn't work (doesn't connect to router even with good password). Because if that i've installed FoxHound Rising 1.5.4 JellyBean Beta and it kinda helped, now it connect to router but lose connection very offten and it take ages to load webpage or doesn't even load it. I've made screenshot, can someone tell my what white thing next to my wifi means?

Ok first of all you need to realise that those roms are BETAS, they are based on LEAKED otas. They are not completely ready to be released to the public yet.
That symbol is for WiFi direct, it's a bug in DLH9 leak and can't be removed unless you flash the WiFi direct fix floating around the forum.
It does no harm anyway.

[Q] MIUI 2.3.4 (stable) wifi connection problem

Hi guys,
Apologies if there is an answer to this anywhere else on XDA but I had a decent look and was unable to find one.
I recently installed the MIUI mod as per the instructions here: http://forum.xda-developers.com/showthread.php?t=1079150
The mod looks great and I did not encounter any problems with the install however I now cannot connect to wifi. After entering in the passkey under wifi settings it simply goes through the cycle over and over of:
Connecting.... Obtaining IP address.... Disconnected.... Connecting.... etc.
Anybody know of a solution?
Thanks
I also had similar issues.. It will connect but frequently drop and while connected, the speed is ridiculously slow.. I wish i could find a solution.. 3g speeds are great and its not the wifi network causing the problem..

this happens to me with my router netgear (is a router issue). i need to reboot router in order to reconnect my defy to wifi. If you doesn't solve try to install latest miui.us 1.8.5, is newest and stable
Just installed 1.8.5 and still no dice. I am also going through a Netgear router so that may be the issue however reboot did not fix the problem for me.
Update:
Currently logged on to wifi at work with no problems at all so it must have something to do with the router. Is there anyway I can counter this by forwarding the IP address through a port or something?
Interestingly, I am also having the same problem with my bluetooth. My car stereo has bluetooth for hands free and I can instantly pair with this device but cannot connect to it. It again just gets stuck in a "Connecting...." loop but is never able to finish connecting.
Am I missing something simple or should I just give up on MIUI for the moment in favour of something else such as CM7...
I just updated my Desire and same issue.. any solurions?
Give CM7 A try... wait for a while... there will be an RC update with 2.3.5

you have tried the 2.3.5a stable? has no problem
It might have something to do with the base Android system you had before. I've read that flashing the Nordic sbf, then rooting it, full wipe (factory reset, cache, dalvik) and then install might fix your issues.

I had the same problem with CM7 RC1 (RC0 worked), with Barebones Froyo and now with MS2Ginger... It connects to the router...but the internet speed is really slow... I changed the router to G mode and nothing.
With MIUI 1.8.5 my wifi worked ok...

[SOLUTION] Samsung Galaxy S wifi 5.0 and big problem with wifi

My model is YP-G70 , firmware 2.3.5 on original updated stock rom.
My wifi working very well when I used with my others device (HTC Desire, Nook Color and PC) but with my awesome Samsung Player...
Every some minute the player drop the wifi line and after 1/2 second reconnect.
And i loose my download
Incredible.
I turn off Juicedefender, I 've setup the wifi property "Wifi sleep policy" with NEVER, I turn on KeepWifi Service (app) but.. NOTHING.
Do you have some advice?
Help...
I had the same issue when I bought my US model. But I only had the issue with my home wifi and not anywhere else. Can you connect at another location and see if you have the same issue? I ended up just replacing my old Belkin router and haven't had an issue since.

Try installing KeepWifi, see if that works. Otherwise it could be your router configuration, like the kind of encryption you use for your wifi password. Try to reset your router but don't use any password for a little while, if that works, use another encryption method.

I will try, but tomorrow I 'll be in another "wifi area" so with another router...
Solution
I've changed the "Client Lease Time" in my dhcp server (ddrwrt) from 0 to 99999 minutes.
It's working end I don't know why
I read this solution in an old XDA item of this forum. Thanks!!!
Hi
I have the same problem with my G70. For to have the max signal in the device i need to go beside my router. I have try with other router but the problem is the same.
maybe is only the display animation in the screen? I say that because i check the quality of my signal at it tell me GOOD.
im also having this problem on my I9003.
the wifi sleep policy has a bug.
some say that your Security/password should be WPA or WPA 2, they said this happens on WPA-secured routers, i haven't confirmed it though.
the only temporary solution for this is to disconnect or turn off the wifi in your phone settings and turning it on again, then you can connect again.
Due to the ROM,i think.Because wifi on 2.2.1(mine is YP-G1) functions great
Dose G70 have a ROM of 2.2.1?If so,you can try it yourself if you like
well i found a fix for this bug, just download the latest version of WiFi fixer from the Play Store.
that's the easiest way to fix this wifi sleep bug.
Hello, I am having the same problem, but I suspect my situation is worse. I've even tried the wifi fixer app, but my 5.0 drops wifi and breaks large downloads and games that require constant connection.
Do I have a defective unit? Any advice and help would be much appreciated.
Solution! (for me at least) go into your router settings on ur PC and change the lease time to either Forever or 30 minutes ( I can't remember which one). It worked for me... good luck

I had this wifi problem with 2.3.5 it was really annoying . Even if i was a meter from the router the signal sometimes dropped to 1 line. Samsung fixed this problem with the 2.3.6 update, and now the signal is ok.

Not the best solution, but....
I have the same problem that happens with my SGP 5, my friend's IPAD, and the Actiontec Router that Verizon supplies with their FIOS service.
I've tried every other remedy that I can find with no success.
The only solution that works for me is to assign a static IP address to the devices. It results in a very solid and stable connection in both cases.
Hope this helps someone else !!
Thank you all for the advice, but nothing seems to work, and I have no idea how to force it to upgrade the os from 2.3.5.
I don't know what to do now short of sending it to Samsung for service.

Download from samfirmware (or anywhere else) the XXKPL firmware.If you are 5.0 international, simply flash it with Odin. US users must make a new tar with just the "factoryfs.rfs" in it and flash it with Odin. That will upgrade you to 2.3.6. However, if you do that, I strongly recommend installing one of the custom kernels, so it won't be impossible to root.

Problems with wifi on ICS official and ROM Cook (4.0.3 and 4.0.4)

Hi everyone! I am new to this forum. I have something to ask.
Currently I am having an Xperia Ray. Rooted. Boot loader unlocked. Running Ray Onium v7 GB with Aire Kernel v7. Everything runs perfectly without a glitch.
However when I update to ICS, both stock ROM or Cook ROM (Ray Onium v6 ICS, JJ ROM 2.5 and team Kang ROM), I find that my wifi is not useable.
I'm sitting about 1m away from the router, the signal is excellent but I can't browse the internet or go to the market.
I have tried both with 4.0.3 and 4.0.4. However when I connect to an open network, everything is fine. I'm using WPA2 encryption for my Linksys 54g router.
Any help would be appreciated.
Thanks!

I've been having similar problems with my wifi since updating to ICS. My problems are a little different though. WPA2 network here, the phone can see the network fine and it connects quickly, I can browse and stuff just fine, but every so often the network just /disconnects/. Usually it'll reconnect a few seconds later, but sometimes I have to open the wifi settings screen before it'll reconnect, and sometimes it doesn't reconnect at all. When it doesn't reconnect at all, the settings screen says my network is either out of range (it picks it up the moment I hit Scan) or had an "authentication problem", and I have to manually connect to the network.
Kinda weird and very frustrating, because sometimes I'm connected for hours without a problem, and sometimes I'm getting disconnected every few minutes.
When SE released their alpha and beta ICS roms, the wifi either didn't see my home network, or it saw my home network but couldn't connect, instead just infinitely cycling through "Connecting, Disconnected, Not In Range, Connecting"
Same problem happens regardless of what kernel or ROM I use, it happens in CM9, AOKP and every other ICS ROM I've tried. :/
A similar problem it seems...
When I want to download an app via Google Play simply it doesn't start. I touch back button and try to download it again and voila! The same fast wireless..
But it simply does not start at first try. Not only Google Play downloads but also all other internet using applications do that strange behaviour.

I have two Rays at home... one on GB and one on ICS.... the ICS one has the same problems, I think switching your wifi router to WEP seems to help and so is changing to B from N.. but then you lose higher speeds and security... but that does seem to help. On the other hand the GB ray has no problems whatsoever....
Hope this helps someone figure out a solution

Your welcome. I just also flashed official Nordic 4.0.4 from here... And my router has something called " protected mode", that is says helps for that- if WiFi signals are too many around. Try installing WiFi analytics from google play... It's free-
use a free WiFi channel.
Turn on such protected mode if you can
I also activated something called "intellistream" that prioritizes streaming in WiFi.
So far, it's going well. This way I kept the 801n and WPA security.
Before this, I was sitting 7-8 steps away from the router and kept dropping connections.
Hope it helps.... No expert here.... Joined the forum for the same reason...
tomorrow after work ill test as much scenarios as possible. it cant be router related since i have the same issue with 7 different routers. 0 problems with GB, always the same issue on ICS.
connected solid and sound, no dropping in signal, but no internet flow whatsoever.. this is the only thing that keeps me on GB -.-
Any progress?
Yeah same problem with me.
There's something wrong with ICS Rom, that needs to be fixed
Replace file
Unzip and copy this file in /system/bin (replace with original). This should fix the wifi connection. You will need root for this.
So far, so good

Jellybean wireless possible Fix

Hi,
Like many others I've had issues with WiFi staying connected since using the jellybean leaks. I had the same with CM10, but if I go back to a stock ICS rom then it works fine. if I reverted back to any jellybean rom then again it will not stay connected.
For me the issue is fixed by change the security on the router from WPA/WPA2 auto to just WPA. With this it connects every time. If I set my router to use WPA2 then again it drops all the time, so it would seem that is has an issue with WPA2.
Maybe others want to give this a test to see if it works for them. Currently I am using DLH6 stock leak.
Maybe this has been posted elsewhere but I thought I would share my findings.
Cheers.
Not working for me. Wifi drops when I move away from the router

Confirmed here.
Im using a beta version of Omega v15 based on DLH6.
I could not connect to wifi no matter what I did.
tried router reboots, changing wifi channel etc.
The status when connecting showed:
- Authenticating (normal)
- Obtaining IP Address (normal)
- Saved, Secured (should show connected)
This repeats several times, before eventually the status shows
Network disabled. Poor connection.
I then tried configuring static IP
This time it connects for a fraction of a second then disconnects and instead of the message 'Network disabled. Poor connection', now it shows:
'Temporarily avoiding poor connection'
I then tried installing different kernels - no improvement.
The only solution that worked was configuring network as WPA only.

Here's my fix go back to ics
I get absolutly no connection.. :crying:
From what I've read these tips might also help:
- Change WiFi channel to a free one
- Disable 5Ghz wifi on your router
- Disable 802.11n on you rrouter, just use 802.11g
Hopefully Samsung fixes these issues before releasing official 4.1.1
With the leaked JB stock rom my Wi-Fi works fine. However, with anything related to AOKP or CM10 I now cannot connect at all. It worked previously but something has changed in the last 10days to stop it. I flashed the leaked initial leaked JB stock rom and that's when the problems started when I went back to CM10.
I have a Netgear DGN2000, WNDR3700v2 and also edimax range extender. It prompts me for the password, tries to connect but then just saves the config without connecting. Tried with/without 5g, g only etc.. still no joy.

Use Odin to flash a stock ics Rom and that will fix the WiFi problems on cm10

I tried all solutions that are mentioned here. But I always get disconnected when I move away. I'm at 100% ICS stock rom (updated through KIES today) and still not solved.
Going to bring it back tomorrow and hope to get a replacement or a fix by samsung.
IMO:
your modem changed when you flashed the leak Rom. Easy way to fix You must flash modem through or odin or cwm. or any stock ROM via odin.
(nothing to do with your WiFi router.)
Have you guys tried updating the firmware of your router?
no problems for me.
using Omega v14 (XXDLH4)
Baseband (XXLH1)
Connecting fine with (WPA, WPA2, WEP)
If the problem is with the modem guys, why not use another modem or the one previously used in stock ICS?
How will a modem help WiFi when WiFi is a product of the kernel ??

I have no idea. I just made that suggestion because I saw the other guys discussing using a different modem.
Anyways. The kernel I'm using is the one that came with OMEGA rom, which is the stock kernel that came with the LH4 firmware.
Just to say that this wifi 'speed fix' actually fixes this connection issue for me

[Q] WIFI tether completely broken

I have a droidX with liquid ICS 1.62,
android version 4.0.4,
and kernel version 2.6.32.9-g34b306d
i have tried every possible method i have found to get wifi tethering working, its to give my nexus 7 wifi on the train
I'm able to tether with bluetooth, but because there's no wifi connection various apps dont "see" the internet and ignore it.
so i need wifi tethering
BUT IT WONT FREAKIN WORK. :crying::crying:
more specifically, no matter what i try, nothing can see the wifi tethering signal of my phone, its as if nothing is there at all.
it'd tried; Foxfi, PDAnet, wifi tether for root users, barnacle tether...
i'm completely at witts end here, ask me any question you need and i'll answer in as much detail as needed
anyone? at all?
if you need any more information, i can provide it
guess not
i'll probably have to drop back down to CM7, it looks like every single ics or jb rom for the droidx has this dumb issue. thanks verizon
wait, nevermind, got it working again somehow
after flashing back to stock liquidICS 1.62 i found it working again
i tried to underclock the phone so i could leave it in my pocket running wifi all day, but apparently under OR overclocking the phone AT ALL breaks tethering, dont ask me how or why.
if you change the clock speed at all, you need to reboot before using tether
