I am getting a maximum lousy 1,5 MB copy speed between two Macs on my local network. My hardware is:

  • iMac6,1 (2006)
  • AirPort Express A1264 (2008)
  • MacBook Air3,2 (2010)

The AirPort and the MacBook are both 802.11n-compliant according to my findings, but the iMac says "802.11a/b/g (draft-n disabled by default)".

  1. Is 2MB/s the best I can expect with the current hardware?

  2. Is "draft-n" something I can "enable" on the iMac? If so, how?

  3. What speeds are the best possible between units that are all 802.11n?

1) I do not think so.

2) You need Apple Extreme 802.11n Enabler for Mac, more Information is How to tell if 802.11n-enabling software is installed or an OSX Update. See HT2447.

  • @dor: Using the "How to tell" method, it says "/n" on the end on the iMac. What next?
