Router as Access Point and PSN help.

[AJV171]

I bought a Tenda W311R+ Router off eBuyer recently, and it is absolutely 100% fine for Internet Browsing. But with PSN, it keeps signing me out in random intervals. I've got UPnP enabled, I've even DMZ'd my PS3, but nothing. A weird pattern I found earlier was, when PSN dropped, so did a Skype call to my mate on Facebook. But the Internet itself still worked always. It's just being used as an Access Point from a Virgin Media Ethernet port in my wall in my house. I've changed bandwidth from 20/40 to 20 and back again, enabled and disabled these WMM and APSD functions, and changed from WPA to WPA2 and vice versa, but no luck. Any guidance here would be useful.

Anyone got any suggestions? Sorry to bring this up again, but I really want my network to work.
