I've got a problem that just started that I can't figure out.
Two computers connected via lynksys router to Toshiba modem (using
comcast) with identical cabling.
1. P733 Desktop running WIN98SE
2. P800 Thinkpad running Win2K
When I run speedtests (from several locations) the desktop speeds are
very low 100-240 kbps. Run from the thinkpad the speeds are normal
(1100-1400). This just started in the last couple of days. What
could be causing the slowdown on one computer? I switched ethernet
cables around to see if that was a problem and did a registry restore
to before the problem started and ran the usual anti-virus and spyware
checks and have come up with nothing. Thanks in advance for any
ideas.

OK, normal should be about 3000 now (Comcast has increased download speeds
recently). I just tested at 3391. I have no idea why your connection is
much slower on one machine than the other though. Try the tweaks listed on
broadband reports on BOTH systems. Before you do that though, you should
shut down ALL components, then turn them back on in the order cable modem
(wait a while), router (wait a while), then desktop computer and then
notebook. -Dave

Make certain the Desktop didn't switch it's network port to 10-Base
(10Mbit). It's sometimes buried in the network card properties. If it's
set to Auto, try forcing it to 100.

I would also consider upgrading that computer to Win2K or XP. Win98
support is over. No more security patches will be out for Win98.

I thought MS decided to support Win98 through 2006 now? They changed their
mind!

Thanks much for responding. Running the tweak test and changing the
tcp receive windows setting per the recommendation seems to have
helped. Three tests subsequently have shown download speeds of 850,
1100, and 1900. Still can't figure out why I had this sudden
problem, but thanks.
Regarding your comment:
I have never seen speeds like that with Comcast. Back when they were
using E *** , I had 1100-1300 download. After they dropped E *** , my
speeds (on all computers) dropped to max of 800. When they increased
speeds recently, I was back up to the 1100 rate I was at before. I've
always assumed it was just the area I was in.

Thanks for the response. I tried changing the network port from Auto
to 100 but with no improvements. Network performance is incredibly
aggravating. Occasionally normal, usually slow (just tested at 52
kbps down and 250 up!)

The XP upgrade I've been putting off, but you're right.
Thanks again.

I spoke too soon. Back to slowwww again.

When you do the speed test on the slow computer, is the other computer
hooked up at the same time? Have you tried connecting directly to the
modem? Have you tried multiple speed test sites? I get wildly different
numbers, depending on which ones I use.

I have experienced this problem before due to a defective network card. It
was a cheap brand, SMC I think, and replacing it with another card repaired
the condition.
