Windows 7 - Ethernet controller

I have a Atheros AR8121/AR8113/AR8114 PCI-E Ethernet Controller and all of a sudden in the past week when I turn on my desktop I'm not connected to the internet, I'm using a Home network and no others. I diable the adapter and enable it and I'm connected again. Strange any ideas?
Windows 7 Pro 32 bit

Does it connect if you leave it for awhile ? I know mine doesn't connect as soon as the computer is started but thats good because it means the security programs get loaded before the computer goes out in the wild and gets into trouble.

Can't really offer much advice about it, have you looked at it in Device Manager to make sure everything is OK there ?

I checked it out in device manager and all is well, I even updated the driver so I am ruling out the adapter. A UNKNOWN NETWORK shows up, I didn't notice that before. I suspect System Mechanic might have something to do with this. I just don't know why though.

I have no experience with System Mechanic so can't comment on that. Where does the Unknown Network appear ? How do you connect to the Internet, do you have a router and is it secure ?

I believe I have solved the problem it was with my software, as always Thank You for your help and I suggest anyone that has a Unknown Network creating itself look at recently installed software.

Glad to hear that you have solved your problem, what software was it that you think caused the problem ?

It was the Iola System mechanic, it was configured wrong. I uninstalled it and re-installed it, updated it, and set it up to work like I want it to.

Right, you did mention that software earlier, good work in getting to the bottom of the problem and solving it well done.
