Verizon wireless router + Netgear Wireless card

I have just setup Verizon wireless with their packaged wireless router. I
have an old dell desktop -Windows 98 with a RJ-45 cable from the NIC to the
wireless router and then I have an IBM Thinkpad, Windows XP-Pro with a new
Netgear wireless card.

The wireless access is fine but on the Windows XP-Pro (wireless) I now don't
see Network Neighbourhood. I want to use the shared printer on the Dell
workstation. Why would I not see Network Neighbourhood option ? It was
there as an option before when that laptop was setup on an office network
(RJ-45 cable) - and when I had the laptop pre wireless card connected to the
Verizon router via RJ-45 cable.

Any help appreciated.

Thanks.
