Hi thereHoping someone can helppast few days various wireless devices are failing to get an up address from router ... I haven't changed any setting on router or devices and this has just started.I've checked dchp pool and plenty of addresses so don't think is issue there.Only way I've been able to connect it by switching to the 5ghz band or sometimes if I reconnect on guest profile 2ghz which I previously switched off .. rebooting router don't seem to cure issue it sometimes works but not often enough to make me think it's really doing anything.I generally have about 8-12 devices connected at 1 time wirelessly so don't know if is some sort of bandwith issue coming into play although last week and months previous I've never had issueThank in advance
