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.

[Q] Wifi tether won't work, rooted KF and Evo 4G

I've searched several threads, but can't figure out what I'm doing wrong.
Both devices definitely 100% rooted with superuser working fine, permissions granted for all apps.
I installed wifi_tether_v3_1-beta14.apk on the phone.
Device Profile: Evo 4G
Setup-Method: Initially I tried Softap (master). That's the same as infrastructure mode, correct?
Default SSID (AndroidTether)
MSS Clamping checked
Routing Fix checked
If I attempt to run it with these settings, I get a popup informing me the wifi hotspot started, but with errors. The log just says most of the wifi steps failed, I can post details if needed. I don't think it's really running - no upload/download indicator showing at the bottom of the app. My PC can't see the hotspot.
If I switch Setup-Method to Ad-hoc, it runs fine, no errors, PC can see it and connect to it. But KF can't connect to Ad-hoc... so lame.
So, I got ZT-180 Adhoc Switcher.apk for the kindle fire, to switch it to ad-hoc mode. Went to settings, told it to connect to AndroidTether. Switched to Ad-Hoc mode. It says "attempting to connect" ... after a minute it gives up and keeps retrying. The hotspot shows in the list of wifi networks, but it's hanging at "Obtaining IP address".
So, what's the issue? Infrastructure mode not working? Need to flash a custom rom? I read something about maybe needing a non-stock kernel? Upgrade or downgrade my radio?

I finally found a method that works, barely.
Wifi Tether (app listed above) failed.
Adhoc Switcher failed.
Wifi Hotspot Widget failed.
Elixir2's hotspot widget failed (connected but no surf).
The one that worked is free and doesn't even need root apparently: Foxfi.
I say it "barely" worked because even this has issues.
When I tried to create a password, it wouldn't connect.
But if I leave the password blank (no password) it does work.

I just told it to start running, and left the SSID at the default (FoxFi98 I believe).

SGH-i747m ping / internal lan issues

Hey all, ive been having issues with my SGH-i747m, I had the app Unified Remote (connects to my local PC over wifi) working fine until i (Kingo ROOT) rooted the phone to install a firewall (AFWall+ , Droidwall , and a few others). After installing I now get no ping response from the PC end, and i have an older galaxy s1 that replys to pings and works with unified remote.
Assuming the root or firewall apps broke something, I then installed TWRP recovery Formatted the data partition and flashed CM 12.1.. but the problem remains, no internal LAN pings or connections.. really strange..
TLDR:
-Started on OEM 4.4.2
-root or firewall apk killed LAN connectivity
-Formatting Data in TWRP and upgrading to CM 12.1 did not fix the connection
Do i need to format more partitions to get wifi LAN? or maybe odin? thanks

I suggest flashing a stock ROM, perform a factory reset in stock recovery, flash TWRP, and then root by flashing supersu from TWRP.

Oh ok, so before trying CyanogenMod i did try restoring the phone through settings>security>reset phone option, not through recovery though, i assume these are different things?
thanks!

ok using this app : https://play.google.com/store/apps/details?id=com.ddm.iptools
running a traceroute to my pc i get an infinite loop of the phones own internal ip, with a 0.2ms
my working phone stops at 1 hop with the correct ip of my pc @ 3ms
i understand what this means, i just have no idea what to modify / reset to fix this

FIXED - http://superuser.com/questions/701956/android-devices-dont-know-route-to-a-host-located-in-the-same-network
i considered my router being the issue, i was about to reset its settings, when i checked my DHCP client reservation settings, somehow there was a bunch of new very strange entries, so i deleted all the unknown entries and the phones are all pinging now
i assume the router got a bit messed up when i was fiddling with adding a DDWRT router repeater
thanks for bearing with me

Xiaomi Mi A2 lite Wifi HOTSPOT Tethering issues on OSX - WRONG PASSWORD

Hi all, I have a brand new Xiaomi Mi A2 Lite phone with Stock ANDROID one firmware.
Android Version: 9 pie
Security patch: 5 February 2019
I have just Unlocked bootloader, flashed TWRP and Magisk, but I'm running on stock firmware.
I have the following ISSUES:
ISSUE 1 - When tethering a wifi signal, all my mobiles devices can connect and navigate, except for my working device, a Mac running OSX 10.9.5.
When I try to connect the signal, I type the password and the system gives back INVALID PASSWORD, even if the password is correct.
I found HERE ( https://discussions.apple.com/thread/4580644 ) and here ( https://apple.stackexchange.com/que...ection-has-password-issue-with-my-macbook-pro ) that the problem is due to the fact that OSX misunderstand a 2.4 GHz signal with the 5 GHz.
I've double checked and the HotSpot Wifi is a 2.4 GHz signal.
Switching to 5GHz and than back on 2.4 GHz does not work
Rename the hotspot does not work
Changing the password does not work
Rebooting does not work
Adding manually the WiFi SSiD and password in OSX Network preference does not work.
I'm out of ideas, and the Macbook with OSX is my working device, so I need tethering on the go.
Didn't try with Bluetooth or USB tethering.
ISSUE 2 - I have 2 sims, when tethering from SIM 1, the devices that works with my hotspots are able to navigate witouth problems.
when moving the data from SIM 1 to SIM 2, the tethering does not send data, and i'm unable to navigate.
Any help and suggestion is really appreciated, i don't want to switch to LINEAGE due to the fact that I have just set up the stock rom with my personal apps

Any news or suggestion on how to solve those issues?
I was able to make it work with MAC OSX without WPA2 Personal password, leaving WiFi open.
The problem is that I work in a School, so there is an high risk of students to connect to my personal hotspot, how can I force to only be 1 device to be connected? It was possible with AOSP Kitkat, why is not possible with Pie?
Any Magisk or Xposed module?

I have the same issue with OS X 10.13.6.
No problem with paranoid android pie beta but can't use tethering with stock firmware.

This might sound crazy but how can i fix this wifi problem?

Background: oneplus 5t with lineageos 16
Can detect WiFi signals but wouldn’t connect to my own WiFi but mobile hotspot & other people’s WiFi
what was on my screen after i entered the password:
connecting...
saved...
connecting...
saved...
after a while
Disabled
My other devices have no problem with WiFi connection
Super weird, isn't it? does anybody have any idea how to fix this?
Trials and errors:
1. Changed WiFi frequency: 2.4GHz & 5.0GHz
didn’t work
2. Changed WiFi name & password on both frequencies multiple times, i even made my wifi public with no password(2.4GHz & 5.0GHz), still my oneplus won't connect
didn’t work
3. Reset network settings on oneplus
didn’t work
4. Rebooted my router and phone
didn’t work

Maybe try a clean install. Backup then wipe : system, data, cache, dalvik. Then reflash. Titanium backup app is recommended.

I don't have this device myself but, you may want to see if you can locate/obtain some support and guidance within the following Official LineageOS 16.0 thread that's specific to your device.
https://forum.xda-developers.com/showthread.php?t=3843026
Good Luck!

Is *your* wifi SSID hidden? If so, forget the connection on Lineage 16.
Re-add it:
When you add it back, *before* you enter the password and hit save, hit Advanced and make sure "Hidden network" is ticked.
