My sister just got back from a semester abroad and her computer won't detect our wireless network. She's working with a laptop with IntelPro wireless (b i think). The router is a WRT54G with a mixed b/g network. It does not appear in the Available Wireless Networks window. I'm working on the valuable information that when she got over there she "changed some stuff" to get it to work in Wales. Is there any reason why it would not detect the network at all, or any way that I can reset all settings for the wireless adapter?
