Forget that solution - much easier way but you will need a second wifi client - a PCMCIA card will do nicely and is not that expensive.

It involves sharing you first wifi connection thru the second wifi connection. I will post more soon. First you will need a 2nd wifi connection - forget bluetooth in this situation. Actually although I';ve never tried it I guess a bluetooth adaptor connected to the laptop could replace the second wifi adaptor but again I've never tested this.

search something like hotel sharing in ITT. I posted it somewhere.
