was advised by a technician regarding my tg585 modem to use a channel not in use.
problem is , I have no way of scanning my immediate area for which channels are being used already by wireless handsets and the like.
he further suggested that there is an Iphone application which does this nicely , and are eliminating all the channels that are in use , I maybe able to get better reception through-out the house on one that is not being occupied.
Cheers.
