Also,
I am having issues with my apple devices on this router, however this is not the first router than I have had apple issues with, since the move up to IOS 8.1.
This morning on my Apple iPhone 5s I have a full signal on 5Ghz, however the internet is not responsive, the only way to get it to come back is to turn the wifi off and on. Then it comes back for a little while. However today I reset the network settings on the device to get the internet back.
Not sure when and if Apple will sort these issues out, not sure if there is anything I can do other than use 2.4Ghz on apple devices for the time being as this issue doesn't seem apparent on that band.
