You could try dropping your LAN mtu to 1006 and see if it helps. It wouldn't surprise me a great deal if M$ was screwing up the IP fragmentation/defragmentation.... > Question 2: > > For the past couple of months my modem would just hang up for apparently no > reason.

Any assistance > is greatly appreciated. [.....] This may be happening due to an unforgiving modem and a bit of line noise. There's a register on your modem for adjusting the amount of time carrier can be lost before the modem reports it. On USRs, the default is quite low (about .2 of a second?). I usually set it to about 2 seconds. > If you need any more info please let me know.

Try getting the latest version of ppp (http://www.Awfulhak.org/ppp.html) and enabling ``debug'' logging - it's not as annoyingly verbose as the older versions of ppp, but gives you lots of information.... try the modem setting first though (from memory, I think it's S10). -- Brian <brian@Awfulhak.org>, <brian@FreeBSD.org>, <brian@OpenBSD.org> <http://www.Awfulhak.org>; Don't _EVER_ lose your sense of humour....
