Public bug reported:
Using Intrepid, Intel 4965 I am noticing long pauses on my wireless network. I
have tried both the included intel driver and the backport modules as suggested
by the release notes and neither solves the problem. In order to diagnose
this, I ran ping 192.168.1.1 (my gateway) on my linux laptop. At the same time
I ran ping -t 192.168.1.1 from my Windows laptop. I do not see the issue on the
Windows laptop at all. Here is the output from ping on the linux system:
