Re: Wireless needs configuration at every start-up
D-link must be the brand and Ralink the chipset in it (linux sees the chipset, not the name of the wireless card maker). Also have you tried leaving it in roaming mode (in system>administration>networks)? It should make all networks appear. Or you might want to use wicd instead (for some people it works better than networkmanager).
"Some people says that if you run a Microsoft Midori iso backwards you will hear demon voices commanding you to worship Satan". But that's nothing. If you run it forward it will install Microsoft Midori.
