I've been having a problem with my CFW PS3 since yesterday.
I was playing GTA 5 yesterday and I suddenly got an error saying something about parental restrictions. It signed me out of PSN and I tried to sign back in but it just says a connection cannot be established.
I have tried the following:
Using a wired connection
Using a bridge connection through my computer
turning off the console
Connecting to my phones mobile hotspot.

Each time I tried any of the above it just gives me a message saying "The key Information exchange timed out. The WPA key you entered may not be correct"
I am 100% sure I am using the correct password for my router.
When I try to test my internet connection it fails on the Obtain IP Address and gives the same error message.

I also tried changing Rebug firmwares to see if it could make any difference but I still have the same problem.
My current firmware is 4.81.2 D-Rex.

Thank you for reading and any help is appreciated
