Same thing here today. Followed suggested remedies no luck.. I can connect other device using the same password, but not my playstation. it was working fine until upate.
SONY are you following the forum????????????????????
I am still having this problem. Someone mentioned that Sony was fixing it. Do we know if that has happened? I assume I'll have to connect via wire for the fix since wifi is a no go now.
Folks....I can tell you right now that this has NOTHING to do with my router or existing internet connection. I work for IT so I know quite a bit about technology, and all of my other devices in my home work just fine. In fact ,a 2nd PS4 in my home did NOT receive the update and is working with no problems. Get someone with technical/server experience to assist with the issue and dont let Sony lead you to believe its something wrong with your internet provider.
Tried a whole bunch of things.... still nothing.
I can connect using a cable (but it's not a permanent solution)
Actually I take that back. I can connect with a cable but I can not go online?
I think the closest I can get to going online is removing my password from my wifi, which doesn't sit well with me.
