So, I set a WEP key on the linksys (WAP11 v. 1.1) and it promptly disappeared… it stopped responding (over the WIRED network) to my wap11gui admin tool. I quickly realized that part of the problem is from having two network cards attached (both in the 192.168.0 range)… disconnect the usb card and reconnect. Then I use the “security” tab to enable WEP (128-bit)
