I have a really weird networking issue on my Mac Pro (Early 2009). I can’t get higher network speeds than about 2MBit/s. It doesn’t matter if this is over AirPort or one of the Ethernet ports. An iMac and a Mac mini in the same network with almost the same configuration get about 25-30 MBit/s. I’ve read a couple of things about this on the official Apple forums, but there is no helpful information. Anyone else with Mac Pro network speed issues and who knows how to solve them?
