I am running Ubuntu 12.04 64bit Desktop

I am connecting to my home Wi-fi using wep key, like I do with all of my other devices. There is no issue with the wi-fi as none of my other devices have this problem.

Every 5 minutes give or take, I will get a request to enter the WEP key for my network. even though I am connected with no problems. Through trial an error I have learnt that choosing either connect, or cancel will give exactly the same result. Another notification saying Wireless disconnected - Yet I am still connected, everything is working. I just continually get the request to enter my WEP key, I am connected the whole time, despite the alerts I receive. Its quite irritating having to have to stop working on whatever I am working on at the time, every 5 minutes just to get rid of the WEP key pop up.

I have also checked my drivers, I have the correct one for my wireless. and it is working and active.

Has anyone else had this issue and know how to resolve it? Hope someone can help.

Cheers
