AP50 slow with latest iOS devices

Hi,

I have an AP50 running with the latest UTM release (9.107-33).  I've had the AP50 for a few months, but have never been able to get particularly impressive throughput from it when using it with iOS devices (I have an iPhone 5s and an iPad Air).  From a computer connected directly to the UTM via Ethernet, I get around 85Mbps down and 35Mbps up.  From my MacBook Air connected via the AP50, I get similar speeds - around 80-85Mpbs and 25-30Mbps up.  This is pretty much what I expected to see across the board, and shows the AP50 is capable of high speeds (so it's apparently not defective).

With my iPhone 5s or iPad Air connected via the AP50, I'm lucky if I see 15Mbps down, but do often get 20Mbps or more up.  I've had rare occasions where I get download speeds in the 30Mbps range, but I've never seen anything close to the speeds I see on my MacBook Air.  Meanwhile, my iPhone and iPad get 70+Mbps down at my local Starbucks (Google Wi-Fi), so I know these devices aren't the issue.  It all seems to point to the AP50.

Anyone else experienced this?  Is there some compatibility issue between Sophos access points and iOS devices?

Thanks,
Martin.

Thanks for the tip - I segregated my network into two SSIDs, one at 2.4GHz only and the other at 5GHz only, and had the iOS devices join the 5GHz network. This seems to have helped considerably. My iPad/iPhone don't quite reach the same speeds as my MacBook, but I assume that's mainly a hardware difference - I expect the MacBook simply has larger and more powerful Wi-Fi antennaes.

and a faster system cpu...by quite a bit.
