Well I purchased my Sony external Network Adapter, have my Disk and code and all looks good. I look at by UK BT (the main link supplier-millions sold) broadband connection modem and its a USB end. No USB provision on the Network Adapter. As its in the next room, my plan of attack is get a new Modem/Router which I do and thats working fine, now lets play online...oh no another issue. The client end Wi-Fi is USB and of course no USB provision on the damn Network Adapter.
After spending the cost of new PS2, I'm fed up and have resided to the fact I will never play online.

The only answer seems to be if there is a manufacturer thats built a Network Adapter that fits into the back of the PS2 as it should, but provides not just a Ethernet Connection but USB as well. Anyone known of such a thing?

You just have to "hard wire" from the PS2 to a modem-router using a cable

The PS2 is about 10m from the Router, so running a cable was an option but not practical or pleasing to the eye. Wi-Fi is what everyone tells me to do, but client Wi fi ends are all USB. I checked the Xbox 360 spec and they have Wireless via a USB connect, so I would find it hard to believe that there isn't a Network Adapter that supports both types of cable?
