It has been happening more frequently now that I had to move my main desktop to a wireless card and built a media pc that is also wireless.
The router is a dsl modem / wireless router combo from Verizon, a 327w Westell from 5 years ago that came with the service. The modem itself stays connected to the internet over the dsl line but the machines that wirelessly connect to it just lose connection. They can still see the network name but can't do anything on it. To fix it all I do it disconnect and immediately reconnect, things will then work for another day or three until I have to do it again, usually after first turning on one of the PCs.
Any ideas on how to fix this or is the modem getting old? Can things like that really even wear out? The modem is b/g, the wireless cards I am using are b/g/n. Wireless mode on the modem set to 11g only. Everything running Windows 7.
One of the problems I have is that I am in a condo so I have wifi networks all over the place around me. The router isn't too far away, its 22 or so feet away in the hallway off the living room. Wifi scanner picked up 7 N networks and 16 g ones. Many are very weak but everything is bouncing around in the same area.
I have changed the channel to one that isn't too populated. I had been at 11, I changed it a while ago to try to improve transfer speeds that were not going about 400k. I'll try to get an N modem router this summer. I have also made sure that the properties of the wireless devices are not set to allow for power downs.
