Hello,
thanks for the answer.
The hardware version is A1, firmware version 1.06b05, I'm in Europe, Italy.
The dir 505 is in repeater mode, with extended wireless with different SSID from the main.
The main router is set up to 54 Mbps for b/g networks, wpa-personal both on dir and dgn.
I 'm also using a dlink DAP1160 to connect a sky decoder in another room, used as a wireless to cable converter and it works perfectly. The tv I'm trying to connect now used to work with the DAP.
