Re: Network slows down every 60 seconds

Thanks again Chuck for your help so far. On your latest suggestions, I have
confirmed that I am running the latest driver for my NIC (an Edimax PCI NIC
with antenna on an extension cable). I have also just tried disabling RWin
AutoTuning, and this made no difference.

A colleague of mine has just bought a new Vista laptop, and I asked him to
carry out the same experiment at his home, running "ping -t <router>". He got
somewhat similar results to me - every 20-60 seconds, he would get one packet
that would take a lot longer that the others - a few hundred ms - to be
returned. Also, he had one packet time out. This differs from my results in
that my long-turnaround packets seem to be regularly every 60 seconds, and
take up to 1900 ms. So it seems that on a random sample of two Vista PCs,
there is something going on that slows down the network periodically and, in
my case, this is to the extent that RDP sessions time out.

If you have any further ideas, I'll be keen to try them!

Thanks in advance,
Stephen
