I have a Netgear wireless b/g router WGR614 v.6, firmware version V1.0.11_1.0.7NA. Often when a laptop connects to the router, the speed ramps down to 18 Mbps. If I go to the router management page and change the channel I can usually get it to connect again at 54 Mbps. Then a week later it will connect at 18 again until I change the channel. There does not seem to be a "best" channel. RIght now for instance I am on channel 4 at 54Mbps. Last time I had to go to channel 8. It does seem like the extreme channels (1, 2, 10, 11) are never good. It also does not seem to have anything to do with location or how many PCs are on the network at the time. I have Windows firewall enabled on all of our PCs. Disabling has no effect. Any ideas?
