Wireless internet adapter for Linux?

Both my laptop and desktop connect to the internet, but my laptop doesnt have any internet access?

• I'm running 3 computers in my house on a zyxel router, my netbook (running xp) connects to the router and also has access to the internet, my desktop (running linux) connects to the router and also has internet access, but for some ungodly reason my laptop running windows 7 connects to the router, with no internet access. Heres what i've tried: Taking a client off the network resetting my network adapter using a usb network adapter resetting the router updating the network adapter drivers

• Answer:

  Have you configured your router to only accept certain mac addresses? It should be under wireless > Wireless MAC Filter or something similar. Outside of that, that is about the only thing that I can think of.
