[Q] WIFI connects but no internet?

Today I updated my ROM from LeeDroid v2.5 to v3.0.8.2. I wiped my phone first. After this I rebooted, then rebooted again into recovery and installed the recommended radio (32.56.00.32U_5.17.05.08). Then I restored my apps+dat with Titanium back up and rebooted again.
It soon became apparent that whilst mobile internet was working fine, WIFI wasn't. While my phone will connect to the router it won't connect to the internet. If I enter the local IP of my router I can browse the settings fine. I tried "forgetting" the network and re-entering security code but this still didn't work.
I restored my v2.5 nandroid backup and the internet worked fine, the radio is still 32.56.00.32U_5.17.05.08.
So I did a fresh install of the v3.0.8.2 ROM and tried connecting to WIFI again and again the same problem.
So my question is, is this an inherent problem with the ROM, and if so why does no one else seem to have this problem, or is it a setting issue?
Any help would be much appreciated.
Also I tried changing the WIFI channel as suggested in another WIFI thread, and this didn't change anything. Except the WIFI channel obviously.
And I tried a static IP address and that didn't work either.

You try turning off router and putting back on again? I sometime's get that in my network.

Yes I tried turning my router off for a couple of minutes then switching it back on. Didn't change anything.

Did you sort it?

I think you need to wait before the router give your router assign an ip for your phone, btw, some router donot fit all phone model

Yes thanks I managed to sort it today by following this thread
Apparently the fault is inherent to Android 2.3.3 and seems to present itself mainly with Thompson routers. It was a static IP I needed, I'd not entered the details properly the first time.
Thanks for the replies!

WiFi not turning on?

Ok so a couple of days ago I installed a 4.0 ready radio on my galaxy s2 and then went on to install Jedi Knight 6 ROM (4.0.4 and radio is UVMC6) and after installation everything was working fine.. I was messing around for a while.. it worked today, I shut my phone off to charge it up real quick, and when I turned it back on my WiFi would not connect. Well not necessarly connect.. it just wont even turn on. When I go into settings and click WiFi, it just sits there saying, Turning WiFi on, and never changes.. I can't seem to imagine what could have happened to it, and I really dont wanna have to reinstall the ROM again because i just spent hours getting this one all set up to my liking...
Anyone got any ideas?
EDIT: BTW, I have tried many things.. Tried airplane mode to disable everything then turn it back on, obviously tried rebooting the phone, i have tried wiping cache in CWM recovery and also tried fix permissions in recovery (another topic said to try those..)
Nothing has worked so far, i'm about to try reflashing my radio, see if that works.. but I really really dont want to have to reflash my whole ROM.. So if anyone has any other ideas please help, i'll edit if the radio works..
EDIT 2: Reflashing the radio did nothing.. it's really wierd, the data, bt, gps.. all of it works fine, it's just the WiFi that's frozen turning on... cant get it to stop turning on and can't get it to actually turn on..
EDIT Final: Ok well, i guess nobody knows what might have been going on.. so I just wound up reflashing my ROM, which obviously fixed it.. i just had to lose all that time spent setting everything up... But oh well.. Kinda sucks nobody even tried to help..

+1 I'm going through the same thing now

I have been having this same issue as well. It started out as stock happening sporadically. One thread suggested rooting and removing my account. Problem still occurring. Tried flashing multiple ROMs and now WiFi hasn't connected at all always stuck at turning on. I have tried clear cache, fix permissions, as well as reinstalling ROM dirty and with factory reset. I'm hoping this isn't hardware failure because I just bought this phone used but it seems to be a reoccurring problem with others as well. Any NEW suggestions not given from quick Google/xda search?

I'd suggest to check your Wireless Access Point (modem or router) wireless settings for security, check and see if it's set to use WPA/WPA2, which is common on some modems/routers, change it to either WPA or WPA2 (preferred) not both, it's a known issue with WiFi networks and having it set to using both, I had the same problem before with my phone connecting to my WiFi.
Also if you use MAC Address Filtering on the modem/router, you should disable/clear that and let phone re-connect before enabling mac filtering again.

The problem I am having is not that it won't connect to a particular network. Wifi will not initialize on the device at all and is stuck in "Turning On..." state. I found more and more posts where people ended up having to send in to Samsung so I spoke with them and even though I purchased the phone used its thankfully still under warranty and they will be replacing it. The did not confirm whether or not it was a true known device issue but were quick to file the exchange for me.

sigh, me too!
Just started having this problem on 4.3.1
great.

In my case, I had to wipe system and data before reinstalling my ROM.
Though the only reason it was happening to me was because Beanstalk 4.4.2 didn't want to get past the splash screen when I tried to install it so I downgraded back to ICS 4.0.4 without wiping. Good luck getting this issue fixed. Also another kernel might fix thingz for you if your current one does not like your device.

I have a similar problem. After a while, WiFi gets disconnected. If I go in settings - wifi, i get the message "unfortunately, settings has stopped" and I can't get WiFi to work again until I reboot the phone. The Wifi works again for a couple of minutes then stops.
I have flashed various different ROM (CM11, PA) but keeps getting the exact same behavior.
I've rebooted in safe mode and I don't get the problem now.

[Q] SlimKat 4.4.4 and WiFi Reconnect issue

First, I've had this issue since Build 6.8. I was hoping a Clean Install using Philz Touch Recovery v6.48.4, which is the latest, and selected Wipe Data and select Clean to install new ROM which Formats /data, /cache, /system. I also wiped Dalvik.
Once completed I did the following:
Clean Install of Slim-d2lte-4.4.4.build.7.0-OFFICIAL-5979
I then installed
Slim_full_gapps.BETA.4.4.4.build.7.x-190
Rebooted and waited for SlimKat to boot-up. WiFi/Data both full scale. Everything Restored just fine and things are running smooth.
Then after running a few errands outside of WiFi Range, I returned home within WiFi range only to find out that WiFi had not reconnected. It tells a WiFi connection is available but will not reconnect to it. So I go into Setting and select WiFi and tried to manually reconnect. It says connecting and then goes back to Saved Connection without connecting. This same thing on other WiFi connections such as McDonald's or other open WiFi Connections.
I then do a re-boot and everything is back to normal. WiFi connects without issue and again things are fine and running smooth.
Every time I leave WiFi range and then return within WiFi range, the problem re-occurs. A Re-Boot and everything back to normal.
One thing I've always noticed when doing a Clean Install as stated above, all of my previously stored WiFi connection are still there. Same on Ringtone/Notification Tones.
With the problem I'm having, could it be something that is not being wiped/cleared out during the Clean Install process. Or wondering if it could be somehow that the WiFi Radio has gotten corrupted.
I have also tried different Kernels but again the result is the same.
Hope this is not too much of a noob question and I have searched about everything I can think of. Wondering if anyone has had this problem or have any ideas of what could cause the problem.
I really hope I can get this figured out. Thanks

If you don't have to manually reconnect and enter your password, then its not being wiped. (Or you are restoring it from a backup.) Have you tested it after the clean flash, but before restoring anything? What are you restoring and how?
It sounds like a Rom issue otherwise and you should probably ask in the rom thread.

First I don't know what I've missed wiping. When I say restoring, I'm referring to letting Google re-downloading everything from the Play Store.
I know the WiFi radio are in a different location but like you, when I do a Clean Install by formatting /data /cache /system and wiping dalvik, I wasn't expecting all the stored WiFi connections to still be there, but they are.

Its possible its being restored by Google's backup, but I don't use it myself so I'm not certain about that. Its also possible the rom may save the config file elsewhere. Again though, I don't use cm/aosp based roms so I'm not too familiar with any of their specifics.
Next time you try a clean flash, do not sign into google during setup. Instead go straight to testing wifi to see if it still remembers the connections. Do you have it set to auto connect to any open networks? If so you might want to turn that off.
Have you searched or asked in the roms thread yet? It might be a known issue or something a few others have encountered and know how to fix.

Ya I don't sign into Google at the initial start up after the flash because my WiFi is no able to connect. I will double check the auto connect feature. But I having this issue with other 4.4.4 ROMs also because I tired however on those ones I am amvle to toggle WiFi on but in advanced it has the region set to Europe and when I switch it to Canada it doesn't want to save the change

Wifi passwords lost after reboot

just bought p607t and immediately I installed 4.4.4 with a firmware from sammobile. Now the only issue i got is Wifi autoconnection. Every time I reboot the tablet all my wifi passwords are gone, and no autoconnection. I have to manualy enter the passwords everytime i reboot. I have tried on different places (coffee shops) still the same.
I tryed and installed AOSP rom just to check if its software isue, and on aosp wifi passwords are remembered even after reboots, everything is fine.
i would like to know if anyone out there is facing the same problem and if u found a fix.
Thank you

found the fix

I edited build.prop in /SYSTEM folder and changed the line: ro.securestorage.support=true from TRUE to FALSE, rebooted, added the wifi password and everything is fine now wifi passwords are remembered.

No Wi-Fi, no Bluetooth and no FM Radio [D855]

I'll try to give as much information as possible.
Yesterday I was surfing the internet and suddenly my phone froze and randomly restarted. After that I wasn't able to connect to wifi nor bluetooth. I was running android 6.0 with 30B modem, rooted and with TWRP. After that I flashed Modem from v21C Firmware. I don't know if doing such was responsible for the next thing, but my Wi-fi mac adress and bluetooth adress disappeared from Hardware information. Note that my IMEI information did not disappear.
After that I did a full factory reset with .TOT method. That didn't solve my problem. Tried upgrading to lollipop, did not work. I've done like 10 factory resets only today, I've tried to fix persist partition following this guide http://forum.xda-developers.com/google-nexus-5/general/guide-to-fix-persist-partition-t2821576, same results.
In 4.4.2 and 5.0(all versions I tried from lollipop), both wi-fi and bluetooth adresses showed up as anavailable. Sometimes after rebooting, my phone would connect to wi-fi and show my mac adress, and would crash after 30 seconds..
On 6.0,my mac-adress shows as 02:00:00:00:00:00 and bluetooth adress as unavailable.. Need some serious help here, tried so much stuff nothing worked..
I'll attach some screenshots that may be useful
Any questions and any tries to help me are highly welcome.
Enjoy 6.0 on your phones and thanks for reading :fingers-crossed:
-------------------------
Edit:
Adding some logs. Half a year passed, no solutions.
1 out of 100 reboots wifi works. I've gathered some logs of 1 of the moments wifi works. Hoping someone can figure something out. Tried lots of roms, nothing seems to work.

Forgot mentioning that both wifi and bluetooth show as trying to connect on notification bar, but when I go to settings and press on them, both say "turning on (wifi or bluetooth)" when the button is grayed out and off..

did you tried to use the cse flash in flashtool to fix this?

Did CSE flash, normal flash, TOT factory reset, wiping wifi's definitions.. Nothing seems to work :crying:

More info:
During the night, I removed the battery from the phone and booted my phone. After that Bluetooth would work, and Bluetooth adress would show up on "Hardware informations". Then, I turned off bluetooth and tried to put it back on. Bluetooth adress disappeared and my bluetooth would not turn on. Hope anyone helps..

How about your imei?

I think I found a solution but I can't test it since I'm having problems connecting my phone to my PC ( another problem appeared..)
May I ask yo to install busybox and try this on adb?
adb shell
su
busybox iplink show wlan0
and see if it shows your real adress, if it does
busybox ifconfig wlan0 hw ether (adress)
busybox iplink show wlan0

I don't have my phone with me, sent it to repairing. Any news?

I'm having a very similar issue. Wifi and bluetooth won't turn on and cycle. On some reboots, Wifi will turn on but the phone will shut down shortly thereafter. I've tries several different ROM's and can fix the Wifi, but no the power not the shutting down.

I'm having the exact same problem but a bit worst. I can't even turn my phone on. Phone came back from repairing, guy couldn't fix it. Tried some rom's, many "fixes" from the internet, nothing. Seems like the only way to solve this will be by hardware..

exactly same problem with my g3 too
even i was using stock 30b firmware and after one week of usage it suddenly crashed and stuck in bootloop hence downgraded to lollipop and tried all roms,factory reset,different modems etc but still not fixed
waiting badly for an solution

I'm having pretty much the same problem, along with overheating and screen fading. I'm using stock Lollipop, never rooted. I've tried a factory reset and a new battery with no results.

Any solutions?

Guys I've sent my phone to a local repair shop and they said they took it to LG's official partner.. I've been waiting for a while and it doesn't look good.. A friend of mine bought a g3 recently. I suspect this problem comes from a corrupted or missing file. I'll ask him to help me on checking files if the local shop can't find a way to fix the phone. If everything fails, the only possible solution I see is a new main board or a new phone..
