My superhub 2 keeps dropping wifi connections and the only way to reconnect through wifi is to rest the router it's a daily occurrence. There's only 6-7 devices connected and 1 of them on LAN which isnt affected on drop outs.
It affects both 2.4 and 5g, the devices say connected but no Internet. Hardwired devices are fine. All devices connected by WiFi drop at the same time and only way to reconnect is to turn off the hub and turn back on after a few min's. This is now happening 3-4 times a day.
