Flash a new kernel, it's a common problem also check your radio you may have the wrong one and yes wifi binaries are region sensitive for broadcom chipset also download wifi manager and set your channel above 12 and 5ghz to your region
P. S. This problem even exist in notebooks
And windows users have bad time when it happens
As said by Spider623, it can be either Kernel (99%) or the Radio issue.
Please try other Kernel also check if you have correct Radio as per the android Version and your Region.
All the Best.
Thanks Ambuj and Spider, but there is no radio or kernel available for the RAZR!!
DEVS please help?? I full wiped yesterday, and today it still does not work. I am downloading MIUI 2.9.14 now. If that doe not work too I will switch back to stock...
Hi!
I have the same problem from time to time. Solution is:
1. Turn Off Wi-Fi.
2. Use Root Explorer.
3. Go to data/misc/dhcp.
4. Delete the only file on this directory.
5. Now you will connect to Wi-Fi.
