Wifi password not recognised

Wifi has stopped working on my KDL-43W755C TV. The TV recognises the network as a 'saved network' but says that the wifi password is not valid. I have tried re-inputting the password lots of times but get the message 'wifi password not valid' or 'password (WPA) invalid' depending on which way I try to login. I have tried the suggestions on the discussion boards. Any ideas? Thanks in advance.

Re: Wifi password not recognised

Something like this happened to me. I had to start over first "forgetting" the network that I was previously connected to.

Then I accessed the WIFI from Expert Settings. It seemed like Easy Settings did not work. Try that.

Thanks for the links, I have tried the suggestions but still no luck. I have also emailed Sony Support and so far have not made any progress.

Hi MarkVideo, Thank you for your suggestion. I have tried Factory re-set and forgetting the network, whichever way I try to creep up on it the TV won't recognise my password as valid. I have emailed Sony Support again.

Re: Wifi password not recognised

Solved! A recent auto update on the TV made it incompatible with the security system on my router. All of my other devices at home continued to work - the problem was just the TV.

 

SONY customer support were not helpful - by email they asked for a long list of codes and used a lot of jargon that I didn't recognise. A very nice man from SKY spent an hour on the phone with me talking me through various tests and changes until all of my devices including the TV were working. 

 

I had to change the security settings and change my password for the wifi.
