I have an 802.11ac router at home with both 2.4Ghz and 5Ghz connections and separate SSIDs for each. In most parts of my home, the 5Ghz connection is utterly useless, which I learned the hard way from my phone regularly connecting to it and then failing to do anything while it does. So, of course, I told my phone to "forget" the connection.
But since Google backs up all my WiFi networks and syncs them with all my devices, which is a great feature, it constantly restores this WiFi network to my Nexus 6 (and did the same to my 5 before that) without my realizing it until I notice my phone being useless at home again and find that it's reconnected to it. I'll forget it again, it's fine for a while, and then after an unknown period of time it's back.
Anyone know how to PERMANENTLY forget this network from my Google account?
