PSN error 80710092?

[Arroganteggnog190]

I've been getting this error at least 3 times a week recently while every other device in my house connects without a problem. I usually have to wait hours before my ps3 will connect again. If I do an internet connection test, it fails the 'Internet Connection' part, even though the internet browser on the ps3 connects fine. I've tried everything and a wired connection isn't possible.
