Thanks for the prompt reply!
LAN connection: I mean that it doesn't work because I don't have internet connection. I bought the Mobo yesterday and set Windows up today. For a VERY SHORT moment between installs it WORKED!
Wireless is defined as slow because: I take less time to use the portable than the PC to communicate and browse. It works, just bad reception (on the other end of the apartment, small as it is!).
LAN connection: green light.
Before the change of Mobo and software (from Vista to 7) the LAN worked perfectly.
What else could I tell you to identify the problem?
