Both sides have to agree to the setting.  ie if the switch is set to 
autoneg, your network card must also be set to autoneg and vice 
versa.    Unless its a managed switch, leave the NIC as autonegotiate.  If 
its still failing, I suspect its something with the re driver.  Its 
possible the NIC and switch dont like each other (it has happened in the 
past with certain vendors) but this is pretty rare these days.
