This sounds like the classic problem of a duplex mismatch between the device
and the hub. A lot of folks don't realize it, but when you mix
10mb/HDX/100mb/FDX devices in a single network - you would THINK that the
devices would autonegotiate identical settings on both ends. C'mon, they
even SAY they autonegotiate on the box, and they DO have an 'auto' setting,
right? Fact is, they get it wrong better than 80% of the time. Even two
devices from the same manufacturer usually don't autonegotiate right.
Pretend that "autonegotiation" doesn't exist. Set both ends manually to
identical settings. If one
Some will say - this can't be... I plug them in and they work, and the right
speed lights come on! And they pass traffic JUST fine. Don't trust this.
FDX/HDX mismatches can create very odd looking wierdness. Like a connection
that SEEMS to work, but is actually working very poorly.
