[Q] Wifi and bluetooth not working with any rom, solution? - Galaxy Tab Q&A, Help & Troubleshooting

I'm facing a big issue since two weeks:
I've replaced my wifi_supplicant file on my tab (froyo rom) and rebooted the pad.
As soon as I turned the wifi on, a few seconds later, it automatically disabled switched off.
So I decided to flash a new rom (stock gingerbread). This time, the pad keeps rebooting after switching wifi on. Also the bluetooth can't connect to any device.
I flashed again a stock froyo rom, erased everything etc... the issue still remaining.
I noticed that other people are facing this problem but I tried everything (flashed a new modem, many roms, custom roms etc...) , the wifi and bluetooth doesn't work.
Do you have any solution?
Thanx.

bluetooth and wifi

hi guys, i have this problem. i have downloaded installed JACHeroSki2.7.4 rom on my g1. its been working fine but i seem to have a problem with my bluetooth and wifi. they both dont turn on. ihave turned off my phone but still no joy. does anyone know how to fix this. also does the led light dont work on all of the hero ros?
Bluetooth doesn't work on any Hero ROMs for the Dream, so that's why. As WiFi try wiping and reflashing, if that doesn't work it's a ROM issue. LEDs are working at about 60% brightness on most recent Hero ROMs, send yourself a text to test it.

Nexus one Wi-Fi is corrupted...

Hi everyone,
I was driving from Wash DC to Montreal about 3 weeks ago. Once I got to Syracuse NY my N1 just froze. I took off the battery and then it wouldn't boot. ( I was running frf50 + froyo radio since the first day it was leaked). I thought maybe a routine wipe would fix it. It didn't work. I was out of options and had to wait until I get to montreal to use a laptop and see whatsup. Once in Montreal I downloaded a Rordriguez Froyo and the phone booted up. Now the problem started. Wifi doesn't work. Whenever I turn it on it says unable to scan for networks and then another error pops up saying " Sorry! Activity wifi settings (in application settings) is not responding." I tried a million different roms and radios and the problem persists... Yesterday I flashed another froyo rom and wifi worked and actually connected to my home WLAN. Then suddenly it stopped working again... Can anybody help me? this is so frustrating, especially since I have only 2 bars of EDGE in my basement. I think it might be the Wifi driver that is causing all this. If somebody can link me with the Wifi driver I might be able to fix this problem...
Thanks!
PS: All radio related stuff work ( bluetooth, 3G...)
if you flashed a lot of roms....and it didnt work, chances are its a hardware issue, not a wifi driver issue as thats reinstalled with all roms

[Q] WIFI connecting intermittently. HELP!!!

Hey Everyone
I recently installed XXJVB (2.3.3) onto my sgs and it works really well. my only issue is that the wifi connects sometimes and sometimes it doesn't. This happens at home often and is really annoying.
Does anyone else have this problem?
And does anyone know how to fix it?
Thank you for any reply's
I haven't experienced it.
First thing to try before you go any further.
Turn off everything that connects to your Wi-Fi router. Unplug the router from the power supply for a minute, then plug it back in. When it boots back up, see if the problem still persists.
Also, Have you tried a factory reset prior to or after flash?
had that issue when I played around and installed a cpu tool from the market: my wifi acted up same as yours. As far as I could deduce it was because the power/sleep settings were altered -- beyond my pay scale. Uninstalled the offending program and rebooted: the whole system was hickey and media scanning was an issue. So, did a recovery restore in cwm and all is well again.
Suspect the issue is the set up for power management. sleep policy and the other internal setting sin the kernal being out of phase with each other. Do a retore to the last stable system you had.
I have also leanred the value in doing a complete backup before I play with any new themes and mods: that way restore bails you out!
Did you notice that on version 2.3.3 wifi sensitivity worse that on previous version?
Using "Wifi analyzer" application I found that on Gingerbread kernel signal weaker then on 2.2.1 by about 10 db.
I've tried to use modem JPY (from 2.2.1) instead of native JVK but it didn't help.
It looks like somewhere there are wifi parameters that should be configured properly.
SOLVED
Thank you everyone for you input
@electrotune1200
Thanks for your idea's. The whole turning router off and on worked. i feel rather stupid cause i have to do that often so that i can get my laptop to connect, never even crossed my mind to try it for my phone lol.
Thanks again everyone

[Q] CM11 WiFi Connection Issue

Hey guys! I have only just joined XDA Developers so please excuse me if I have posted this thread in the wrong area. I have a Samsung Galaxy S Advance (GT-I9070) running stock Jellybean firmware (4.1.2 ITV) but as you all know the stock firmware for this device is full of bugs and freezes often. I successfully rooted my device and installed Team Canjica's CM10.2 ROM (4.3) from the thread on XDA Developers but the WiFi wasn't working. I then installed Maclaw's CM11 ROM (KitKat) because I thought that might solve the issue but it didn't. Here are the details:
Device scans for nearby wireless routers.
I type in the password for my home router.
Device saves router. "Saved, Secured" message displayed.
I tap on my home router in the list to connect.
Device says "Connecting" for a couple of seconds and then goes back to saying "Saved, Secured".
I browsed through the forums and some users suggested switching WiFi Frequency to Auto and turning off WiFi Optimisation but neither of those methods worked for me. The ROM was installed successfully and all other features are working properly so I don't think that is the issue. And my router settings are also alright since I am able to connect to it from my Nexus 7 (2013) properly. Can someone please provide me with a working solution for this issue? I will start receiving very high data usage bills soon because my data plan isn't unlimited. Thank you!
Is your ssid hidden (not broadcasted) by any chance? i had those troubles on hidden home network. Sometimes it worked after a while, sometimes it didn't. What helped me is to broadcast ssid for a moment, get connected with phone, remove broadcast (it will reboot router so phone will lose wifi for a moment). Then somehow it got connected normally
Sent from my SGS Adv. using xda-developers app.

I just checked my router settings and SSID Broadcast is enabled. I tried flashing OmniRom 4.3 thinking that this may be because of a problem with CyanogenMod but the problem still persists. Is there any additional kernel that I was supposed to install perhaps?
CyanogenMod 11 version ?

Just a detail to those who have not upgraded to JB stock and think it is impossible to use it without problems:
All bugs and freezes in Stock JB currently are perfectly finished.
I use STOCK, only with modified kernel (cocore 8.2) without freezes or bugs in months of use.
Enjoy the developer's work (cocafe), because without it JB probably would be impossible in SGA. However we have JB 100% functional and bug-free.
About KK and WIFI bugs:
The only KK (or based) ROM that used without WIFI bugs was RR 20140313.
In fact, the only issue is incall vol. in my experience.
WiFi Direct, Camera -> Panorama is laggy , Screen Recorder not working Not Tested
I also noticed that the battery is worse durability.
But I went back to JB Stock -- personal preference.

Actually I did try that method. Flashed Samsung's latest stock firmware I9070XXLQL (ITV) and then rooted and installed CoCore. To be honest overall performance was much better and UI smoothness was improved. But after a couple of days of regular usage with just a few basic applications such as a note taker, train arrival time, WhatsApp etc. the device started freezing up a couple of times a day again. I admit it worked much better than before but freezes and hangs were still quite frequent. Running OmniROM 4.3 now with no issues so far except for dialer FC, laggy panorama and non functional WiFi hotspot.

This means probably you have typed wrong password. Also check that in keyboard it capitalise first letter automatically. forget the network and connect again
WIFI not working with cm-11-20140521-UNOFFICIAL-janice and cm11.0_janice.nova.201406
Same wifi problem with cm-11-20140521-UNOFFICIAL-janice and cm11.0_janice.nova.20140601. Wifi not connecting even after giving the right password (used to work correctly with jb4.1.2 and still works with desktop) only showing saving and connecting wifi. Then the wifi connection is shown to be saved. If wifi does not work with cyanogenmod11, then what's the use of upgrading?
Is wifi is not working in any custom kitkat Rom?
Please suggest a solution.
Try couple times to connect. I remember sometimes I had to reconnect 2-3 times before it gets connection. And the problem with kernel was about WIFI not turning on at all, it was not even search SSIDs.

wifi and hotspot problem.

hi every body .. i have a problem in my s4 active i9295 .. the WiFi and hotspot and the Bluetooth dos't work .. any one can help??
same problem here.
I cannot active the Wifi nore the Blutooth.
I have swapped the main board with a second "Samsung Galaxy S 4 Active" and the problem staid with the main bord.
I was think of replace the stock ROM with a custom one to se if it a bug within the stock ROM.
Any suggestion?
Just replaced the Stock ROM with CM ROM.
As expected, it did not make an difference.
The OS is trying to enable the WIFI (or bluetooth) for a few seconds and fails.
There moments (both with the custom and CM ROM) when the WIFI and bluetooth did activate but this was short lived.
I am almost convinced that it is a hardware problem.
Any suggestion and advice is appreciated.
