I'm having a network problem that appears to be that the 10/100Mbs ports on my
router are no longer working at 100Mbs, but are working at 10Mbs. Is it
possible that just the 100Mbs part could fail?
Here's my scenario if anyone is interested. Connected to the router are the
following:

It could be a duplex mismatch but I doubt it.
I have had this happen to myself personally, where the 100mb part didn't
work and the 10mb part did.
I assume by router you mean broadband router, not a real router.
Most consumer level 10/100 switches or routers are switching hubs.
That is there's
Every 10/100 device I've seen in the last 10 years has used 1 chip to handle
the 10/100 PHY. This means that it would be (IMO) HIGHLY unlikely that only
the 100Mbs portion could/would fail, I would expect all or nothing.
Based on past experience (is there such a thing as *future* experience?) I
Hey, Larry! One thing to contemplate -- though if it had been working
before, it's not terribly likely to be the problem -- is the fact that
autonegotiation is an imperfect science. As an example, at Cisco, we
always had to peg our server connections at 100MBit on the not-so off
chance that

I've seen this problem a few times.
In one case it was a bad patch cable. The cable worked at

In what way are the autonegotiation specs. deficient? Just curious.

If the crystal on the router that feeds the 10/100 PHYs drifts out of
spec, 100 would stop working, 10 would probably be more forgiving. Is
this likely? No, but it is possible. Just my $0.01999

This router has been working for a year and half with computer #1 (10Mbs) and
#2 (100Mbs) connected to it. The 100Mbs
Hi, Greg -
My, this brings back memories!
Back when our shop still used Microsoft software (but Netscape, never
OutBack!) we saw this same problem. What a pain - even on a Windows
system you couldn't read the attachments!
There were solutions (although not from Microsoft). Here's a URL for

While I've never read the RFC, to the best of my knowledge, there's no
problem with the specs, themselves. Once again,
Once upon a time autonegotiation wasn't standardized. Then it was.
But we still have non-standard gear in service here and there so it
still bites people once in a while and it gets a bad rap. 3COM gear has
been the biggest thorn in my side from this problem - they put out
