How to get rid of 802.1x 'Default Authentication'?

Hi All,

Everytime I close my MBP's lid, put it to sleep, or simply turn it on... My wifi is no longer connected.

this all started ever since I decided to 'Turn Off Wifi' the very first time since I got my MBP this year 2011, in June.

Whenever I do any of the above (put MBP to sleep etc) then get back to working.. My Safari says I'm not connected to the internet.

And I see my Wifi signal "blinking" and trying to connect. So I go to my Network preferences and see this:

There's that '802.1X: Default Authenticating' that appears below my wireless network's name..

After which i have to Disconnect from twice - 1 time, before it tries to "authenticate" again.. and then a 2nd time.. and then it stops completely,

Then i have to proceed to click and choose my network again and re-enter my password just to get the Airport/Wifi working again..

Someone please give me a solution to get my Wifi to automatically connect whenever I switch on my MBP - and to get rid of this annoying 802.1X which does nothing and just continues to try and "authenticate" with no result.

It would be very very much appreciated! Thank You!

PS. I did read somewhere online about 802.11g newer wirelss network cards and how they may have issues with an 802.1x network etc..

Don't really understand it though. Please explain if you could. Cheers
