Inter-adapter interference?

OK, am struggling with a domestic spread-out network from a Belkin
pre-n router, with three wireless PCs and one wireless laptop, all
using 'g' adapters of assorted makes, plus one PC wired to the router.
All working well except the one furthest away (forty feet, two rooms =
three walls and the wireless laptop intermediate between them). This
rogue PC gets a good signal most of the time, but drops connection
rhythmically, timing out and often breaking secure internet
connections. I have changed channels, and done all the obvious things
without anything making much difference. Tonight I was playing around
with the rogue PC and the laptop, and noticed that, running a ping test
continuously on both, whichever one is positioned nearer the router
gets consistent fast response times and 0% packet loss, but the one
further away drops packets every 15-20 seconds (5-8% loss). It seems
that the nearer adapter interferes with the further away. Is this
possible? They are almost line of sight. Any solution other than moving
one of them (not easy, for practical reasons)? TIA for any advice

Some other source of interference is more likely -- WiFi devices are designed
to share service with other WiFi devices. If possible, try a different
wireless adapter in the rogue PC. Otherwise, consider a range extender or
repeater to get a better signal to the "rogue PC".
