Is this problem still present in Ubuntu 12.04?
If so... what's your wireless hardware and what driver is driving it?
Can you reproduce the problem and then run "apport-collect 552749"?

Title:
After suspend network-manager degrades wireless performance
Status in “network-manager” package in Ubuntu:
Incomplete
Bug description:
Binary package hint: network-manager
Running Ubuntu 9.10 on an Asus Eee 1005HA.
When Ubuntu returns from a suspended state (definitely on suspend, not
sure about hibernate) when it had previously been connected to a
wireless network, wireless performance is considerately degraded.
This is shown by Firefox failing to load highly available sites, such
as http://www.google.com/ , and dropped packets when pinging a known
host. This is unaffected by if it were connected to the same or a
different access point when resumed. The only solution is to restart
network manager using "sudo /etc/init.d/network-manager"
