I've been having problems with a few devices (chrome books used as on the wall displays) constantly losing access to see other devices on my network. I think I eventually tracked this down to the fact the devices with the problem were connected to the 5Ghz signal and not the 2.4Ghz signal.
As a temp measure I've now split the SSID names - so the 2Ghz and 5Ghz signals have different SSID names - and this has forced everything onto the 2.4Ghz signal for now - and the problem I think is solved. But why would this be the case? Is there an issue with the talktalk router 5Ghz signal?
