We screwed around with this again tonight. When we do get a connection (we’re having a hard time maintaining it) the router data tells me the connection % is very low. So I’m guessing it has to be an interference issue, but I have no idea why its all of a sudden a problem. His network adapter doesn’t see any new networks and no new phones or appliances have been added in the house. We are far enough from other houses (50 yards at least) that those things shouldn’t be an issue. And his adapter sees the router fine - 4/5 bars. So I don’t get it at all.
I gave him the inSSIDer program but it won’t install on his computer due to some lacking NET software - he is going to get it on their tomorrow. He is running XP, but he was before as well. I messed around with a bunch of his settings tonight to no avail, trying to make sure it wasn’t defaulting to anything weird. I’ve also gone through the router manual looking for ideas but nothing has really popped up.
I wish I knew more about networking. It wasn’t that hard to get this working before. My next step is going to be to borrow his adapter and see if I can connect to the router with my PC. If either of us had another wireless device to test this would be a lot easier.
