I am currently using El Capitan with an Asus Maximus II Formula, but the mainboard has a weird bug that the system freezes when im using the built in ethernet ports. (not only in macos, also in linux and windows)
... so i was using a USB Dongle wich worked fine, but the performance (USB2) was not the best.
Now i want to add a ethernet-card to the system.
Is there a cheap, and simple to install (maybe native?) PCIe Ethernet Networkcard that can be recommended?
