Thanks. I've used AVG many times before. Is the Windows 7 firewall decent?
Both computers are connected by wireless. It's kind of a metaphysical question which one is being dropped, because my wife can see mine from her computer, but I can't see hers from mine. Who's on the network, and who isn't?
It actually goes in and out. Last night, when I logged on, I couldn't see her computer, but later in the evening, I could.
And it doesn't matter whether we use the homegroup, because her computer isn't listed in the network, as seen from my computer, and I think that's why the homegroup doesn't work from my computer.
The previous router was a D-Link 624 (some letters I can't remember offhand).
