Since 10.04 I had a lot of trouble with my TP-Link WN321G.
Despite a great signal strength, it would disconnect and reconnect frequently; and the 'ping' to the access point would vary like
5 ms
67 ms
124 ms
6734 ms
7342 ms
1295 ms
567 ms
In the end, no other choice than plugging another WiFi dongle, in this case a (3Com) zd1211rw; immediately everything is fine.
This is the output of
dmesg | grep rt:
