Hi,

Lately, my S3 encountered the wifi problems as below:
a) connection dropped and reconnect for many times
b) slow speed when connected
c) cant connect at all

I hv tried the wifi connection itself, and it is fine.

I also hv googled the solution...and found that it is the common problem for s3. see link below:

I hv tried the solution shared, eg dialing *#0011# service mode, however the problems are still exist.

I didnt root my phone, and it is as original as it.

Any help from here will be greatly appreciated.

thanks

I never root my phone before, and it is using the official rom.
