Sorry to bear bad news, but from what you've described, it sounds like
you are just suffering from poor wireless performance... - something
which is all too common I'm afraid. You may be able to improve matters
by switching to a different wireless channel, - you'll have to
experiment & see if any channel(s) perform any better. The possibility
remains of course that your particular combination of hardware isn't
very good at WiFi...
