When I moved 9 months ago I had similar problems with two other computers. I fixed it by going into control panel, networks, right clicking on something and deleting something. It was 9 months ago and I don't recall the details.
This appears to be the same problem. Any idea what the fix was?
Since posting it has gotten worse; now it won't connect with Guest either. For the moment I am using a 100' cable.
