Put "speed 100" and "duplex full" on the cisco switch port, and I think 
you'll be better off.

Let autoneg be, it works in 99% of the cases in my experience. Fiddling 
with fixed speeds is more trouble and you have to know what you're doing.

If you turn off autoneg on one party, the other party will autoneg to half 
duplex. If you turn off autoneg, you have to force both ends to the same 
speed/duplex or you'll be in trouble.
