I don't know if its only me, but since yesterday, my PS4 hasn't been connecting to my WIFI, it says the WPA password is incorrect, I have checked that my IP is correct, DNS servers, router, WIFI password, etc. Everything is fine, but it simply wont connect. On twitter I have seen a few people with the same problem, and on the "PSN Status" page it says "Heavy network traffic" so that could be it. The Sony chat support isn't accepting my requests to chat because of "too many chat requests at the moment". This is VERY annoying since all of my games have been downloaded through the PSN store so basically I can't do anything... Have any of you been having the same problem or does everything work perfectly for you?

Nope Its working for me

fixed it, I had to switch the channel of my router, then update the IP, DNS, and other settings on the ps4 and it worked.

it is down a lot nowdays because of Sony problems, i have the same problems.

Switch to xbox mate.

Just switch to xbox one as HorseAFC said ;)
