a decent wifi dongle?

[Mayuresh Kathe <mayuresh%sdf.org@localhost>]

i am currently using a tp-link wifi dongle (thumbnail variety).
not only does the dongle heat-up big time, but it also overworks
my wifi access point to the point of failure. i have tested it
multiple times, with the same results.
would you know of a different wifi dongle which won't cause the
problems mentioned above?
thanks.
