Well, it's 100baseTX. Not too surprising that it maxes out at 12MBps. Up until recently the speed was always automatically set to 1000baseTX. AFAIK nothing has changed in regards to the hardware (contollers, switches, etc.). Anyway, I'll try setting mediaopts in rc.conf and see what happens. -- Gary Jennejohn
