Further to my posting yesterday I have been at it again tody. Still no joy. Mesh shipped the machine with an Asus antenna which I could not make to work. Phoned Mesh and they sent me updated drivers (brand new machine not 24hours old - needed new drivers!!!). This got the antenna to work and I can access inetrnet via the Netgear router - but still no access to other machines on the netwrok. Mesh also directed me to a Microsoft site which talked about loop back addresses but I haven't any idea what that was all about.
Has anybody ANY ideas on where I should go next??
