Hi,    Recently I had cause to unplug my modem and router with specs:  0.1.0 0.9.1 v5006.0 Build 200810 Rel.53181n Hardware Version:Archer VR1600v v2 00000000   Since turning it all back on, I've had persistent problems with the 5Ghz not allowing any devices connected to it to access the internet despite the router dashboard at 192.168.1.1 showing all systems are go.    Annoyingly, at the same time, for some unknown reason, even though the dashboard shows 35 current connected 2Ghz devices, trying to connect another such as my work laptop on my phone of an evening, results in "access point full". Resetting, seems to not work. Haven't tried a factory reset as yet as I have a great deal of smart devices which will need re-setting up, so I wanted to see if a firmware upgrade may work.   Or something else?   Many thanks,   Tom ...
