Awsome LC thanks for your help
Well...here is some info:
Router:
Netgear DG834GT
Adapter:
Linksys WUSB54G
My laptop is just standard its an Advent, if you are in the US I dont think you will have heard of it, but I really dont think the laptop has anything to do with the problem. I used the adaptor easily on another network, its just mine that has the problem. Thats what makes me think its something to do with the router.
Thanks for taking the time to help me out
thanks, Nick
