I have Windows 7 64 bit and a D-link dir 300 router connected to internet through an pppoe. When booting the PC there are 2 connection: "RDS" (my real connection), "unidentified network". I have to manually disable the LAN connection and enable it to connect to internet. When I do this it remains only one connection (the other one disappears) and I can connect to internet. Unfortunately I both the router after I have installed win 7 so I canÃ¢â‚¬â„¢t tell you how the router behaves in win XP 64, but I have another computer connected to the router and he has win XP 32 installed and no problems there. I think it has something to do with NETWORK DISCOVERING FEATURE OF WIN 7. If my rusty English didnÃ¢â‚¬â„¢t explained perfectly the problem, I have uploaded a movie on YouTube. Please help !!! Ps. The router supports win 7 and has the latest firmware. Both desktops have wired connections and I have a laptop with win XP 32 with a wireless connection that disconnects very often (but that is another discussion).
