My Compaq laptop running Windows XP connects reliably (including
Internet Sharing) to my home wifi NW, but has NEVER been able to
connect to any other wifi.

Here's my wifi setup for two desktop PCs and one laptop PC on my home
Netgear wifi:

Netgear WGR614 wireless router connected to a cable modem and desktop
PC #1 via ethernet cable.

Netgear WG511 wireless PC card in #2 desktop PC.

Netgear WG311 wireless PC Adapter in my Compaq laptop.

I set up my home wifi using all the Netgear suggested setup settings.
This wifi NW works fine. The two desktop PCs and the Compaq laptop all
share the single internet connection. File and print sharing work fine
as well. I am NOT using WEP or NW Authentification.

My problem is that my laptop has never been able to make a wifi
internet connection via any other wifi network elsewhere including
public wifi hotspots and a home wifi at my daughters townhouse. Other
laptop users there can use her wifi just fine.

When I try to make an internet connection via my daughter's wifi, I
can see her home wifi NW together with several other wifis in her
neighborhood. However I can't get my laptop to connect to any of
these. I have the password (key) for my daughters wifi, but my laptop
refuses to connect.

What allows my laptop to find, connect and gain internet access on my
homw wifi, but no where else??

Help!
