Wifi not working after rooting

Help My wifi won't even try to connect. It will turn on and i can see my router but when i click connect nothing happens. It worked when i got the phone, i used toast's root then flashed to OMJ EVO 2.1 Eclair v1.3. Didn't work tried flashing with Supersonic_1.32.651.1 and still nothing. then i tried wiping the data and delvic cache and restore with the original backup i made and i still got nothin any ideas

did you flash the most up to date radio?

I was having this problem too, it may be different. My power control would show with the green bar like it was waiting for IP but would not go the bright green indicating it was connedted. If I did it from wireless and Networks it would show "unable to connect" you can find my solution here: http://forum.xda-developers.com/showthread.php?t=699752
I recommend trying this first:
In connect bot on phone, navigate to with
# cd /data/misc/wifi/
then do
# chmod 777 wpa_suplicant.conf
now try to connect from the Wireless and networks in the settings menu. If you can you probably need to do what I did to set it.
Just one question first though, Did you try rebooting the phone? Simple things some times.

Thank you for the input. i've updated radio to 1.39.00.05.31 still does not work. Then i tried changing permissions on the file you recommended...still no luck.
When i go into wireless & networks Wi-Fi will have a disconnected below it. when i go into wi-fi settings i see my home network with "not in range,remembered" under it. After about 3 secs. it changes to "remembered,secured with wep". i'll select it and push connect and nothing happens, it doesn't even appear to be trying to connect.

i noticed something today. Previously when i tried changing those file permissions i simply did exactly what you had said. Did some looking around and the /data/ folder is empty. I did finf the file in /etc/wifi/ directory.

Got Ad-hoc wifi working on my Xoom! (binaries inside)

I've managed to build a version of wpa_supplicant that has ad-hoc enabled, by forward porting the patch in this thread:
http://forum.xda-developers.com/showthread.php?t=754961
After building and a couple of tests, it works.
To install, you need a rooted Xoom, of course, and just push the file to system/bin/wpa_supplicant.
Because zipfiles don't store permission, you have to make it executable as well.
Code:
adb remount
adb push system/bin/wpa_supplicant /system/bin/wpa_supplicant
adb shell chmod 755 /system/bin/wpa_supplicant
I also had to change the permissions on /data/misc/wifi/wpa_supplicant.conf for some reason:
Code:
adb shell chown system.wifi /data/misc/wifi/wpa_supplicant.conf
Then reboot, and try it!
It works with my Nokia N8 with JoikuSpot; I can't tether it any other way as the N8 doesn't support the PAN Bluetooth profile, and Android doesn't support DUN.
Don't forget to backup your files, and I am not liable, etc, etc.
The code I used is here:
https://github.com/kelvie/android-wpa_supplicant

Ok heres what happened to me..
I was able to push the first file and when I input the adb shell code it said the device was not connected I am rooted and had no problems rooting or access shell before
So I got a little cocky and thought that the port 5037 that adb communicates with was blocked so I typed adb tcpip 5036 to see if I could get shell access on that port well now when I type adb remount it immediately tells me error: device not found....help!
Got myself stuck without wifi (error)

Thanks for developing such a great app. If i m not wrong i think its working with all 3G carriers.
You can also turn your Motorola Xoom tablets to WiFi hotspot without rooting by enabling setting which are given here http://goo.gl/mgwdn

Also my xoom has been in debug mode and now all of a sudden I noticed that its not entering debug mode when connected there used to a little icon come up and not anymore it acts like nothing yet i can access it on my computer by going my computer and I see Xoom

Ok I got debugging mode back and xoom is plugged in now my problem is when the daemon server starts in adb shell it starts on port 5038
So when I try to copy "adb shell chmod +x /system/bin/wpa_supplicant" it still says device not found and thats if I copy and paste it exactly if I type adb shell it gives me the # Symbol then i put it "chmod +x /system/bin/wpa_supplicant" and it says bad mode
One good thing is I can now type /remount again so what I am doing wrong still stuck without wifi ;\

Ok I've tried everything except reflash my devices I've literally only been able to do step 1 which leaves me with no wifi because i cannot execute the shell commands so please a little help it's been a long night messing with this appreciate your time and I'd love to get this working!

Ok...I tried this and got the same "bad mode" error at the
"adb shell chmod +x /system/bin/wpa_supplicant" stage.
So, I instead did "adb shell chmod 700 /system/bin/wpa_supplicant" and that was successful, so I finished the steps listed and can see my cell on my Xoom. I have a Windows Mobile 6.5 cell and my Xoom can NOW see my ad-hoc network. Thanks a lot Kelvie.

If not for the SDCard update from BRD, I think this thread would be getting alot more attention.
Not to be too mistrusting, but I am hesitant about loading this on my Xoom when it is posted by a new user with only one post.

I completely understand where you're coming from; but check my github repo, and google for me, I do leave a small internet trail...
I (mostly used to, don't do much anymore but answer the odd email) maintain an open source project (Basket for KDE), and try to participate in open source communities as much as I can.
I just did this to tether my Xoom Wifi to my phone, as I had no other way to get internet on the go.

Nice work. I tried to do this myself last week but ran into trouble just getting wpa_supplicant from the Android git to compile (with or without the changes)

First off, wow man thank you so much. I've been playing with this for a while and I've tried a number of different wpa supplicant files but they failed to initiate a scan of wireless networks. I just tried this one and it works great. I wanted to explain a different way to install it however for the people having ADB issues.
First you want to turn off your wifi. I have used the ADB method a couple of times but I find it easier to use Root explorer. Save the file to your Xoom, Copy it using root explorer, navigate to the system/bin folder and click mount R/W then paste the file into the folder replacing the original (make sure to make a backup!) then long hold on the file and view permissions, check all the boxes in the first two columns and the first 2 in the last column. (chmod 775) You can then restart your wifi and enjoy ad-hoc networks (no reboot needed.)
I've done this a couple of times and it works great. Thanks again.

First off, thanks a ton to the OP for getting this working!
Also, thanks to mr_wrong_0 for the root explorer directions. Not that I'm incapable of using the command prompt, it was just easier to do it this way.

Thanks so much for this! No issues at all. Wifi Xoom is tethered to my HTC Hero now.

Congrats on a killer mod! We are making progress nice and steady.

Installed, works great.
Thank you.

Great, thanks for your hard word.
I do have a question for those how have done this hack. I currently have an old iPhone 3g with tetherme installed and use Bluetooth tethering to give my Xoom (wifi only) internet access. This works great for me.
Is there are speed/battery life advantage to using wifi tethering instead?
Cheers

I don't know for sure. From what I understand wifi is potentially faster than bluetooth, but it can vary from device to device. I have noticed that my Epic seems to stay cooler and use less battery when broadcasting an Ad-hoc network vs broadcasting in infrastructure mode (using wifi tether 3.0.) But I've never been able to get my phone to tether with bluetooth so I don't know about battery life. One advantage of connecting over wifi is file sharing via apps like wifi file explorer. I have used that a lot to transfer files between my Xoom and my phone as well as the computer.

Noob question
Hello all,
Thank you very much for the patch.
I would like to try it out, but before that, I need to make sure of one thing;
If I root my Xoom, will I still be getting future updates from Motorola for the device if there is one? Or once I root it, is it impossible for me to update them from the manufacturer?
Thank you!

Thanks so much to the OP! I've been waiting for a reason to root my wifi Xoom. SDCard access was tempting, but I think this is the thing that pushes me over the edge!!
Thanks!!

[SOLVED] CM7 | Wifi needs a minute to connect | started with nightlys about Jan.

Hi all,
having troubles with my Wifi. It needs a minute to connect and doesn't connect when screen is off eventhough settings are to always on.
I started asking in CM7 nightly thread about my problem but it's better to have a new thread for that.
So far I didn't find a solution.
I tried:
- replace tiwlan_drv.ko with new one by deleting old one
- compared wpa_supplicant, tiwlan.ini and other data in that folder without significant outcome
- tried old 2011.11.16-nightly where it still worked
Anyone got an idea what I have to copy from my old nightly where it still worked?
This is what happened:
measel said:
sorry, for bringing this up again, since I'm the only one having this issue but I just collected a few logs. maybe someone has a clue what is going on there:
Code:
2012-02-13-19-35-37_wifion.txt > when turning wifi on it needs more than a minute to connect
2012-02-13-19-37-37_wifiscan.txt > wifi instantly connects after starting 'wifi analyzer' app or open the wifi settings window
2012-02-13-19-45-25_wifiscreenoff.txt > when screen is of, wifi doesn't connect eventhough settings are to "always on"
/edit: ok i just tried to read the logs myself and I think you can't really see any reason for that behaviour... am i right that the possible settings I have to look for are in the 'tiwlan.ini'?
Maybe someone provide me a backup of his/her tiwlan.ini for comparison... (I don't have any idea what I'm doing but that doesn't mean I couldn't try. )
I added my tiwlan.ini as well
/edit: compared to tiwlan.ini: no differences. Must be something else.

I'd just copy the module tiwlan_drv.ko [in /system/lib/module] from that older nightly and replace it on the newer build first.
Don't forget to set its permissions afterwards..
You can do this with RootExplorer or with Terminal (from the app tray) by entering these 5 lines:
Code:
su
cd /system/lib/module
mount -o remount,rw /system/
chmod 644 tiwlan_drv.ko
chown 0.0 tiwlan_drv.ko
and reboot.

none of these solutions worked right?
I have wifi problems too. Wifi in CM7 is crap

No wifi problems here... I'm using my personal home wifi network most of the time, but other networks works well too.
Red lense German Vodafone Froyo based
CM7.2 Nightly 02102012

I have this issue if I configure my Router security to WPA. With open I can connect immediately

can't really say that. It's great in 111116-nightly so I just wanna figure out what I have to change to get the speed back!
Motorola Defy CM72120121, german Froyo base

I have this problem, too.
Nobody else?
Would be great if some devs could please look this up.

SOLUTION
Hello all,
first off: delete wpa_supplicant and everything is fine!
I gave up and did a factory reset/wipe data. After that it worked w/o problems.
> Now I will restore all my apps and check if it's still working afterwards. > still working
> restore wifi access points > NOT WORKING ANYMORE!
> with shame I delete wpa_supplicant > WORKS AGAIN!
I'm so ashamed. :/ Should have done that like months ago.
I go back to my backup and try it there. > deleting the wpa_supplicant worked!!!!

My Wifi has a problem with WRT54G Wireless Router, with Froyo Stock ROM and CM7.1 RC1.5-jordan.
WIFI connect, signal is good but connection is very slow.
On notebooks, the connection is faster with this same router.
In another Wireless routers connection is normal from Defy. The problem is only between Defy x Linksys WRT54G.
I have set Defy and Router to work only in G mode, but the problem persist.
With the same configurations the problem don´t occour with another routers from D-link, Cisco or other.
Anyone know how can I solve it?
Tnks.

WiFi Connection Issues

Has anyone else noticed this problem:
After upgrading to an ICS leak (currently stock rooted FE22, although noticed so far on all leaks), my WiFi in the presence of a weak signal will stay connected, but not have an active data connection. For example, at work I get 1 bar of WiFi signal shown, and when I first connect I can use data over the WiFi network (market, browser, email, etc.) but after I let my phone sit at my desk for a while and go to use it again, it still shows it's connected to the WiFi network with 1 bar, but there is no data connection (can't communicate to market, browser, etc.). If I disconnect and reconnect to the WiFi network it will once again get active data for a period of time. I have the WiFi setting to always stay connected. If I set it to 'Only When Plugged In' it works fine because it reconnects when I wake it up, but I have a weak cellular signal at work, so this kills the battery faster during background data. It worked fine on the current OTA release of GB with the 'Always On' setting. Any insight/confirmation about this issue would be appreciated. Thanks!

Are you running a customized wpa_supplicant.conf? If so can you please send a copy by PM or copy/paste here after removing any info that you need to (SSID, pw, etc)? Might help understand what's going on - my PEAP/MSCHAPV2 does a "nod-off" but then comes right back up at times. Thought maybe it's a power saving feature as it only seems to happen at times of low demand for data.

I haven't modified anything at all and am running the unmodified FE22 leak, except for root. Here's what my wpa_supplicant.conf file says in its entirety:
from /system/etc/wifi:
update_config=1
ctrl_interface=wlan0
eapol_version=1
ap_scan=1
fast_reauth=1

Pretty straight forward... no surprises there. Do you keep the sleep setting normally as "Always On"? As I mentioned before I've seen mine nod off (go down to zero bars) and then reconnect - usually when the phone is idling.
*Edit* Noticed 3 lines missing from the default:
Code:
eapol_version=1
ap_scan=1
fast_reauth=1
If you're familiar with editing wpa_supplicant.conf you could try to add these lines in and see if it helps. Just don't forget to reset the permissions and ownership or it may give an error when starting the wi-fi.

I tried adding these lines in /data/misc/wifiwpa_supplicant.conf, but then wifi wouldn't turn on. So I reverted back to the old one and now it still won't turn on! I used ES File Explorer to edit the text of the file, and set the permissions to rw-rw---- as it was before then restarted my phone. Any ideas?

Well, in a worst case, deleting it will force it to be copied and restore the service... but let's try something else first.
1) Turn off wi-fi (always needs to be off before modifying that file.)
2) inside adb shell please enter the following commands:
Code:
su
cd /data/misc/wifi
chmod 660 wpa_supplicant.conf
chown system.wifi wpa_supplicant.conf
3) Exit and turn back on wi-fi.
If it was the permissions this will fix it.

THANK YOU! Apparently, I forgot to set the ownership. I only changed the permissions. I also re-added the lines you mentioned. I'll have to see if that works... I'll let you know.

**UPDATE- Still no improvement. It will connect initially, and have active data. But then it will still show as connected with 1/3 WiFi bars, but no active data unless I disconnect and reconnect to the AP and then the same problem repeats itself.

OK, I'm having the same but in all fairness could be because I did 2 nodata updates. Will suggest if you can to backup your stuff and flash the full rooted version of FE22 and see if that fixes it - or hold tight and wait for OTA to drop if it's just nagging you and you don't want to do it now.

Wi-Fi won't connect -Wi-Fi Connection Failure

I'm having a huge issue. My Wi-Fi won't work on my 2013 Nexus. I select it. It sees it with a full signal and I put in the password, It just says saved. I tried with a connection without a password, it says the same thing. I tried flashing back to factory multiple times but it does nothing. It was working and just all of a sudden went out on me. Is there a way to flash a driver or something?

Firstly, just reboot the WiFi access point and try to connect to it again.
Did you change firmware or any settings on the WiFi access point? Do other devices connect to it properly?
Can your Nexus connect to other WiFi access points? Try it with your mobile's WiFi hot spot.
Finally, we need some logs:
turn off N7 wifi
start logcat (I prefer 'time' format: adb logcat -v time > log.txt )
turn on N7 wifi
try to connect
stop logcat
compress and post the log here
