PS3 won't connect to wireless internet

Ever since I switched from MTS to shaw, my PS3 has been having a lot of trouble connecting to the internet. My 3DS, 360, and Wii all have no problem, but the PS3 says I have a successful connection on the connection test yet it constantly signs me out or it's impossible to sign in. Does anybody know what the problem is? It's an error code 8002A548 and after looking it up people seem to think it's something on Sony's end yet I seem to be the only one effected. It's been like this for a few days now

My internet provider. I used to have MTs but they were terrible. Shaw is far more consistent and fast, but there's this one problem

Just run a cable. I have Shaw, am wired and I have no problems.

A friend also experienced problems with Shaw wireless, switched his PS3 to wired connection and problem solved.
