Same with me. So I really think it is not a Hardware Issue. I could have accepted that reason if it is an isolated issue. But based on the thread, it clearly shows that several people is experiencing the same problem. Wifi stopped working right after the .235 update.
If they could only provide us with downloadable file to downgrade to the previous firmware version when wifi could be fixed rather than asking us to bring it to a service center to spend more money.
