I have a Linksys Wireless router that I am trying to secure. When I put in a WEP or WPA my wireless computer will no longer detect any wireless access at all. It keeps saying that wireless is disabled. My computer is using a wireless USB Access Marvell Yukon. I have tried everything I can think of but still can't get the wireless to work with a WPA or WEP. I know that the marvell yukon has its own program to control wireless networks but I want to use windows for that and wonder if they are conflicting. Any suggestions would be appreciated.
