Can anyone help me with this problem please. When I first turn on or log in to my laptop, the wireless signal strength is 'Poor'. But if I go to the Routerlogin webpage and change the Channel, the signal strength goes up to 'Excellent'. but only for that particular session on the laptop. If I log out or shut down, the strength goes back down to 'Poor' again. I have to go back to the Routerlogin page again to change the channel to get the signal back up to 'Excellent'. This happens every time I start up or log in. (Netgear-N 300 Router) How can I get the signal strength to stay at 'Excellent'?. Thanks.
