[BC] Shaw and PS3 error 80029564

I've been having connection issues for quite a while now. When trying to download and install any and all updates or DLC on my PS3 I get the same error (80029564) at the 14% mark of installation. I've tried over and over. I've tried connecting directly through my modem. I've tried 4 different routers. I've had a shaw tech come out and test 'levels' and swap my modem for a new one. All of which made no difference. I am able to download and install on the first try by taking my PS3 to a friends house (who is also a shaw customer) and earlier today I successfully installed a 268mb update over my cell phone after failing 3-4 times on my shaw connection so I'm almost positive it is connection related. I play a lot of Call of duty and lately I frequently see 'connection interrupted' flash on the screen during a match. This only usually last 2-5 seconds and then I can continue playing. Speedtest.net pingtest.net and the shaw speed test all come back relatively normal and i dont notice issues when browsing the web or downloading files. Any help would be greatly appreciated as I've spent probably 8-10 hours on the phone with tech support for Shaw, sony and activision. All of which seem to blame the other for the problem.
