Guys, Gals,

 

My ISP provides 85Mbps service to my house. When I connect my computer straight to the Airport Extreme, I get 85-90 ALL the time.

 

When I connect wirelessly, I only get 30-40Mbps ALL THE TIME, this is connecting NEXT to the extreme, not even 10 inches away from the base.

 

Is the Airport Extreme only able to transmit a max of 30Mbps Wireless Internet?

 

Let me know,

 

Thanks.

    Wireless is much slower than Ethernet.

    802.11n or 802.11g?

     

    2.4 GHz or 5 Ghz?

     

    I see over 100 Mbps between my 2008 MacBook Pro and my 802.11n Time Capsule.

    Your Mac may be a limiting factor; what model is it?

    Granting the truth of Kappy's remark, it shouldn't be as slow as you are seeing, geometal.

     

    A quick test using a drag-and-drop copy of a couple of gigabytes of large files from a fairly old Mac Pro across ethernet to a 5th gen Extreme and by Wi-Fi to a MBP-R's internal SSD showed peaks in Activity Monitor > Network around 60Mbps and average well above 30Mbps. A network diagnostic program I run reports that it has seen instantaneous rates on this setup over 200Mbps (but also as low as 1Mbps); it gives no distribution or average. This is about 40 feet away and through a floor.

     

    What equipment and software are you using to measure your speed? Is it possible that the limitation is in the Wi-Fi hardware of the computer?

     

    You also haven't said anything about the Wi-Fi settings on your Extreme. Is it using 2.4GHz, 5GHz, or both? 802.11g or n? Manual or automatic channel selection?

     

    Have you measured the level of interference and noise in your area? Granted, a one-foot connection should power past a fair amount of background chatter.

    Through an 802.11n Time Capsule via AirPort from a 2008 MacBook Pro:
