"router settings"? can't find that on the PS4 settings menu. it's not under "network". don't know what you're talking about.
what's worse is that if you enter the error code onto this website there is no listing for it. if my ps4 needs to connect to the internet to get sony's fix for the botched update, how will that happen if i can't get on the internet?
this is extremely frustrating and i can't believe it's been a whole day of this for all the customers sony serves...
is sony going to even respond?
the most frustrating thing about screw-ups like this is that there is not any kind of official announcement of a problem from sony. it's like they put the customers dead last. it's horrible that people spend the entire day googling, re-entering passwords, searching up error codes to no avail, getting misinformation from customer service, jury-rigging routers exposing their wifi security, etc. because sony won't just come out and announce anything. like it's been the entire day.
go to your wifi router settings and change your wifi network mode from a/c/n mixed to any other option. this will do the trick. it's temp solution till sony fix this issue.
