Cant get wireless working (by 2 users)

I just got a new netgear wgt624 and the two desktops I wired work fine
right out of the box getting to the internet thru my cable modem. I
named my network and enabled wireless via the admin form.

problem is that I have a sony pcg-k35 with integrated 802.11 b/g
wireless that does not see the wireless network. It should pick up in
range, and I tried also adding it manually. the laptop continues to say
no wireless networks are in range.

am I missing something really basic?
ideas?
