I am using a MacBook Air 11" 2013. In the course of a typical day, my MacBook is connected to multiple access points and routers, both on 2.4GHz and on 5GHz. As far as I am aware, the Almond+ is the only router that is exhibiting the disconnect issue for me.
This is not based on a scientific test; just on observation during the course of actual usage. I have two 5GHz access points installed in my home (one being the Almond+). Both have the same SSID. I have a dedicated DHCP router that both connect to. At least 90% of the time, I am observing that the MacBook is ONLY connecting to the other access point, even when literally in the same room as the Almond+. I typically have to turn the MacBook's WiFi off, wait a minute, then turn it back on to get it to connect to the Almond+.
Whatever the issue is, I am confident that it will be resolved in short order. My purpose here is not to complain, just to inform.
