I recently changed our wireless routers security from W.P.A. to W.E.P.. I downgraded because my sister purchased a internet T.V.box so she can watch her favorite foreign language shows. The box only accepts W.E.P. encryption.
After the changes to our router, the laptop and one of our wireless dekstop PC (both machines with XP) keeps getting disconnected. My sisters' Ipod Touch works fine though. Sometimes it would show not connected but it actually has connection. Websites, I.M. and pinging worked but for only sometime and it will disconnect. I will reconnect (it takes longer than WPA) and would show connected then change to not connected after sometime.
Both PC and laptop only use the MS XP Wireless Zero Configuration.
EDIT: I somehow solved the situation by doing both: a. Changing OPEN WEP to SHARED WEP b. Replacing HEX key with my own.
