I am having the same issue with a host of Apple devices, the wireless stays connected, but just hangs with no or little data being transferred. Two iPhone 5s running 7.1.2, a MacBook Pro running 10.8.5, a MacBook Pro running 10.9.4, and an Apple TV running 6.2. The MacBook Pro running 10.8.5 sometimes requires a reboot to reattach to the network. The device that has given me the least trouble (so far) is the Apple TV. All have no issues with maintaining a data connection on other wireless networks. Things were stable with my old Linksys WRTG54. So, that to preserve peace in my home, I am considering hooking it back up until there is a fix.
It seems that the Almond+ is currently allergic to Apple devices.
