I own a Macbook Pro Retina, a Thunderbold external display and I just bought Airport Extreme 802.11ac and Airport Time-Machine 802.11ac. My Airport Extreme 802.11ac is connected to the router/internet downstairs and my airport Time-Machine 802.11ac is upstairs in my room connected by Ethernet to Thunderbold display which is connected directly to my Macbook Pro Retina.

Time-Machine 802.11ac connected to Airport Extreme 802.11ac by extending the network option and selecting 5Ghz. I was hoping that both Time-Machine and the Extreme will communicate at >1Gbps 802.11ac Speed.

However I’m only getting 1MB/sec with  maximum at 4MB/sec. This is an exact same speed when I used to use Airport extreme 802.11n.

 

Is there anything wrong? I thought the Time machine and the extreme should communicate using 5Ghz 802.11ac, therefore much better speed performance gain?

I would appreciate any advice. Thank you in advance,


MacBook Pro with Retina display, OS X Mountain Lion (10.8.1)

    Regardless of whether you are using a router designed for 802.11n or 802.11ac, the higher (5 GHz) radio band has greater difficulty traversing through objects like walls. Albeit you should get better range on this band the distance between both base stations and any Wi-Fi interference will still be a factor on performance.

     

    Sometimes just a small placement adjustment of either or both of your base stations will make a significant difference. Please check out the following AirPort User Tip for details.
