I have a ps3 which is 6 months old. I use a DSL connection till my router. The computers and the PS3 run on a home wifi connection. From a few days the internet is acting weird and connects and disconnects very oftenly. Sometimes I have to restart the router too. When i test connection is says upnp unavaible, could that be the cause of my continuous wireless internet disconnects and reconnects on my playstation 3??
