I have 2 laptops already connected to my wireless network (integrated wifi card; no issue detecting the network). I am now trying to connect a laptop with an external wifi adapter and it detects all my neighbors networks but not mine (so the problem is not the card). I have had the laptop search for all networks again and the same list appears. I then try adding my wireless network manually including the SSID and WEP code but it still does not appear. I think there is a simple solution but have spent so much time searching that I am pulling my hair out. What am I doing wrong??
