WiFi is broken after rooting

After I rooted, my phone won't connect to WiFi anymore.
I started with the Cyanogen Mod (6.0.2). When I try to connect to a WiFi network, it tries to connect and gets to the "obtaining ip address" message, and finally fails to connect.
I figured I should try a different mod and completely wipe the card. So, I did this via Rom Manager. I had it backup and wipe, then install Skyraider w/ Sense. The same problem persists.
Does anyone have any ideas how I can troubleshoot this problem? Thanks!

Dumb question, but you did re-select the WiFi network you want to connect to, and re-entered the password for that network (if one is required)?

Yeah I have. I've tested this with multiple WiFi networks on each mod. It always gets to the point of "obtaining ip address" which to my understanding means the password has worked. Either way, I'll always long press to forget the password, and re-connect. Even disabling the password on the router still causes the same issue.

No wifi on gedrom.

There is no wifi on gederom or any CM9 rom.I turn on and off wifi and still it doesn't work. I have an Intellinet router.
Thanks for any replies.

You should probably try changing your router's channel. I've heard that channel 13 is bad news ... and I think that was for a cm9 rom. Anyway, it's definitely worth a shot.

Are you wiping cache/dalvik before flashing new roms? If you're going from one developers rom to another developer, you should do a factory reset, then wipe, then install rom. If all you're doing to flashing roms from the same developer, then a cache/dalvik wipe is all you need to do. Hope that helps!

Wipe that kindle clean. Are you using fios? I've heard of a few people having issues with them.

I notice I can't see one particular Linksys wireless router at one of my job sites, but since we have two wireless routers it doesn't really affect me. No idea why...but maybe there is something someone else knows that can help understand the issue?

I still have no wifi and I wiped my kindle fire clean too. I changed the wifi channel from 11 to 4 but still it doesn't work.The connection shows up and when I enter the password the signal strength goes down.It says Authenticating and then it says saved and doesn't connect.
Any Help please.

Try changing from dhcp to static.

Can you go someplace where there is another router? Like I said, I notice there is one particular flavor of Linksys router that my Fire can't see on this ROM, yet at home I have a different model Linksys and there is no problem. Check it out on another router to see if it's just some weird compatibility issue.

Check the router and see if QOS is enabled. If so try turning it off.

I don't have any other routers in my house. With static I still get the same result.
Any way thanks for all the replies.

IF FOR SOME REASON WIFI DOESN'T WORK ON THE FIRST BOOTUP DO THE FOLLOWING:

Enter Terminal Emulator
Type: su
Type: fix-mac.sh
Exit Terminal Emulator

Is there a reason you can't go to a coffee shop, library, or any number of other hotspots with your Fire? I mean if you have a medical issue that keeps you bedridden, I understand, but if not, there are usually routers everywhere you can try connecting to.

Please try connecting to your wifi and then pastebin the output from the following and PM me the links:
Adb shell "dmesg" > dmesg.txt
Adb logcat > logcat.txt
Thanks

The fix-mac.sh fix still doesn't work and I found something with build.prop and settings.db and with some locale things while I was with channel 11 and still it didn't work.
Thanks for the replies.

Daniel120201: I looked at your pastebin logs and here are some notes:
The key lines in your logs are:
logcat: 7551.D/wpa_supplicant( 1040): EAPOL: Supplicant port status: Unauthorized
dmesg: 3949.<7>[ 538.654174] wlan0: disassociated from 00:0e:e8:d5:c5:d1 (Reason: 15)
When I looked up "Reason 15" as a disassociation error, I find:
Reason code 15: 4-Way Handshake timeout.
When I looked up how 4-Way Handshake works:
http://en.wikipedia.org/wiki/IEEE_802.11i-2004
On that page it references CCMP protocol for WPA2 and IPSEC:
http://en.wikipedia.org/wiki/CCMP
And on that page it mentions this:
CCMP is an enhanced data cryptographic encapsulation mechanism designed for data confidentiality and based upon the Counter Mode with CBC-MAC (CCM) of the AES standard
I double-checked the kernel config and low and behold:
#
# Authenticated Encryption with Associated Data
#
# CONFIG_CRYPTO_CCM is not set
I think this can be solved via a kernel config change. Later today, I will create a new kernel only .zip file with this change and I'd like for you to test it.
This also may solve IPSEC issues as well.

Here is a link to the new kernel w/ CCMP support added [Kernel #12 06/08]:

md5sum: e7476ff785b2dfbdb062e1cc036c14ac

Thanks for the kernel Hashcode.It's Works.

You're quite welcome. I think there were a few others who were in the same boat.

Updated kernel Still same problem for me

I am still experiencing this error after kernel update. Too bad this is a very good rom otherwise.:crying:

T210R WiFi Issues

I'm at school where WiFi on my T210R used to work.
I am running Android 4.1.2 on Crash Rom V1.6 with Kernel Version 3.4.5.
Root apps installed are Titanium Backup, Greenify, AdAway, AFwall+ (disabled), Quick CPU Overclock
This is the troubleshooting that I have already done:
-Forget Network
-Turn Off Wifi
-Turn On Wifi
-Reconnect
-Repeat the above, but restart before turning wifi back on
-Wipe Cache in Recovery
-Factory Reset
-WiFi Roaming Fix
The network is built on a set of WiFi repeaters that use WPA2 PSK authentication.
I do not have access to the network (router) settings, so modifying router settings will not work
When entering a correct password, the device will try to connect but will not displace "Obtaining IP Address".
Instead, the device will show "saved, secured" and "authentication error' after a while.
The device will connect to most other networks that I have tried (Tethering on my Lumia 920, D-Link DIR 655 at home)
Thoughts? This is getting slowly becoming frustrating!

I had similar issues when flashing ROMs. It turned out that my router had some security mechanisms in place and conflict was caused when the same device came in with different ROMs on it. My guess is perhaps MAC related. At any rate, a router reboot fixed it. I know that doesn't help you much sorry.

Mobile Data Not Working (not completely)

Hello, I have a rather strange problem with my phone.
After the Update which has just been released (MIUI Global 10.3.1.0 (ODEMIXM)
he began to behave in a strange way my mobile internet.
For example: Youtube, Facebook, Messenger, Google Maps work normally.
And all other applications no longer (even an application to Check system update)
I'm popping up a message: No connection.
I did different things: Reset Internet settings,
change network settings in options (* # * # 4636 # * # *)
and even a hard reset.
if you have questions Yes on Wi-Fi works normally.
Greetings!

Try factory reset first.

mine has similar problems after a call. Some Internet stuff still works, most don't, unless I disable and re-enable mobile internet from the dropdown menu. Did you find a solution, MrKaim?

Same problem in my phone too. The only app which is remain usable of the internet is the Chrome browser. Messeaging apps, navigation, ebay, etc... is always lost somehow the connection: even when I using the app: for example I browsing in the ebay app and after 10mins,its says sonetging got wrong and I can go on only when I turn wifi/adata off and on. And yes, ön my mi mix 2, the problem is still exist on wifi and mobil net too.

Mi Mix 2 Havoc OS 3.7 Mobile Internet
I am facing a similar issue.
Has anyone found a solution for this ?
I'm running a ROM : Havoc OS 3.7 Android 10
Also tried ROM : AICP and Lineage.. Same Issue!
I keep shuffling LTE / 3G it connects sometime but the connection is unstable.
Permanently displays an X in the mobile signal as if there is no mobile data connection.
Please share a solution if anyone has found one.

I realize only some data isn't working but you could save your apns-conf.xml from another setup where you have no data issues and everything works perfect (I always keep one handy) and delete your current apns-conf.xml in /system/etc and system/product/etc and paste the good one in your /system/etc and set permissions on new apns-conf.xml to 0644 using root explorer or whatever root file manager you use then go to settings on your device/networks and internet/mobile network/access point names/ and top right hit the three dot menu select reset to default and wait till you see LTE show in status bar and reboot. If it's an apn issue that will solve it.
My Mix 2 isn't hooked up anymore to a service but I do use it on wifi at home but the apns-conf.xml on stock rom/miui may be slightly different than they are on an AOSP custom rom. I know that's been the case for me on every device I've done this on so be sure if you do give this a shot that you use your miui apns-conf.xml on miui roms and AOSP apn xml on AOSP custom roms so that it will work.
I've been using this process when I have had any data issues at all on my last 3 devices and it's worked 100% every single time when after installing a custom rom I've had no data this works to get LTE going. Credit to spaceminer for this info on the apn delete and swap, data fix as he's who I first learned this from on another forum.

Wifi connection problem

Hi all,
I have a mi 6 phone (sagit). I flashed Lineage 17.1 and root with magisk. When I connect a wifi, I get this error: no internet connection. Strangely, I have connection but some apps do not work with this error. I've tried to change network usage option to "treat as unmetered", and privacy option to "use device mac". But result is same. How I can solve this problem, it is very annoying. (I assume it would be related to router. Not all wifi's giving this error but I could not find a solution on router side as well.)
Best,
