I have a Netgear Router: WGR614 v7 that I've owned and used for about three years now. I've never had a problem with the wireless connection until I installed Windows 7. Not sure if that is culprit or not, but just sayin.
Now for some odd reason it will not remember my wireless password. It will go a few days, a week or so then any device in my house that normally connects to the router via a wireless connection will not connect. It will say the password is wrong.
After going in and reseting the wireless password in the router setup (using the same password), it will suddenly start working again. I've resbooted the router several times, it's got the latest firmware etc.
This is really annoying when my wife is trying to use the laptop and it won't connect.
