Initially, my Wrt160N was working great but after a week it started dropping the wifi connection sometimes several times a day. A power-off was required to get the connection back. Sometimes the wired side stopped working. After looking and thinking for a while I decided to do several things. I didn't do them one at a time and we've only gone a couple of days without a drop. Here's what I did: 1. turn off UPnP - maybe the lone Windows machines was talking to the router. 2. turn off QoS - we weren't doing anything that QoS would help. 3. went wide with 40MHz channels - I don't think this made any difference. Originally, I saw comment here that said that the router would do the wrong thing is it detected too much interference. I don't think that's the case but I don't know. At any rate, I believe the first two changes helped. I'll know in a couple of days.
