When my wife's mac is on our Netgear WAP, my PC can not connect to the internet but I do see the WAP. It has to be something in her computer as it only happens when she is on it. Any help would be appreciated.
Your ISP normally only allows you ONE public IP w/ your home service. In order to share that one public IP w/ multiple computers, you MUST have a router! A router maps that one public IP to many LOCAL IPs on your own home network. What's happening is that each time one computer gets connected, it grabs the only IP available, the public IP. That locks the other computer(s) out.
The reason your WAP works at work is either because it's actually using a router somewhere else in the building you don’t know about or see, OR, the service at work supports MULTIPLE public IPs.
As a temporary fix, if your Windows computer also has a wired network adapter, you could run a network cable from it over to the Mac, enable ICS on your wireless network adapter, and your computer will now share its wireless connection w/ the Mac.
In effect, you’re using your computer as a router. Of course, only you know if that’s practical. And this is only a temporary fix. You should get a good standalone wireless router (or wired-only router and patch the Netgear WAP to it, works the same). Even if you only had ONE computer I would recommend a router since it provides great protection from Internet threats.
