Hell; I have a Thompson TG585v7 router connection to my XP PC via a USB dongle. The distance of the desktop is 10m and there are two walls between the router and PC. As I write the signal is "good" sometimes it is "very good" often the signal is "low" and may even loose the signal. No phone activity or microwave Cooking is going on.
Channels 1 - 11 , these are the available channels for wireless G, and are different segments of the 2.4GHZ spectrum. The different channels are over lapping, so 1 overlaps with 2, 2 overlaps with 3 etc.
If two different channels overlap say; you use 1 and next door uses 4, the channels overlap and the part that overlaps is where you get poor signal or no signal as they cancel each other out.
G has only 3 non-overlapping channels 1, 6 and 11. So these are the only channels that should ever be used.
Start at channel 1 and try that, then 6 an finally 11. One should give you a better signal.
P.S. aerial should be pointing straight up with no metal objects in it's way (metal reflects the radio signal, other materials absorb it).
Hope this makes sense, engineers do not make good teachers - sorry.
