Two private networks

Im using RouterBOARD 751U-2HnD router.

When I start my comuter I dont have network access. When I look at the network and sharing center I see two networks. Work and private.
When I Disable and enable the lan adapter everything is back to ok. After reboot the same thing over again. Dont have the problem
with other router. What could be causing this?

I think this is more of a Windows issue. We have installed many 751s and not had any such problem. Do other machines do the same thing?

I only have one machine behind it. But when I change the router there are no problems.

It’s because Windows see’s the network as a new network and is screwing something up. Try cleaning out the connected networks. I am sure this is not the router.
