I have woosh wireless and Internet phone.
Wot I did was set it all up under windows, then connected my Linux machine and started using it. (no problems)
I was a bit cautious about connecting the Dlink router, but all I did was factory reset the router, logged in to set it up. (really just check it, it's left on default settings). Then plugged the woosh wireless into the wan port of the router and away it went no problems.
Maybe I was a lucky one?
