Re: Network problem

[Dean Hamstead <dean@fragfest.com.au>]

Hi there

I was suggesting to run a sort of stress test. iperf is a network 
performance testing utility which is well known and widely available.

You might consider running some varied tests through the updated driven 
to ensure yourself that its now behaving more stable. On the other hand 
you may find that under high load (or something) that there are still 
problems - which you could then feed back to the driver author.

There are many useful iperf tutorials online, i cant recommend one 
specifically.
