Always need to use network diagnostics

Hi all,

I have to say I'm new to posting on the site, but have been lurking around for quite a while as I have been doing research on a new computer. I have a new MBP 15" late 2011. I had originally purchased an early '11 15" and was still in my return window to swap out for the updated one.

On to my question/problem. Every time I reopen the display after closing it, the computer can not connect to the internet. It always tells me to use the assistant in network diagnostics, or to clear proxies, or other error messages pertaining to Network Diagnostics.

Has anyone had this problem? The first MBP I bought 2 weeks ago did not do this ever, and it just took a brief second to reconnect to the router. Any info on a fix would be very helpful as this is quite annoying to have to do every time I want to get on the net.

Thanks for the help guys!

 

No matter what I do, it keeps making me go through network diagnostics to confirm everything works before I am able to have internet connectivity.

My wife has no problem on her 13" MBP by the way.
