I've found workaround: connect to GPRS first, then to usb. Now it thinks, that I have connection (GPRS) but uses the laest connection (USB).

I don't like wireless, i like UTP cables. At home I jest don't need WiFi, so I don't have any WiFi adapters (excluding my neighbour's unprotected AP, but signal is untable). My girlfriend (and her mother) pricipially don't use WiFi as it is bad for health (I know, that this is unknown an so on, but wires do thei wi do it very good and are much more stable, again no need for WiFi excepting reading at toilet. And if you don't need it, why not to make your mental state more comfortable by knowing, that there is no "danger" radio waves around?). So I don't have available AP near me.
