Hi,   About a week ago my 5Ghz wi-fi connection stopped working. Whenever I try and connect to it I simply get a message saying that I can't connect.   To try and get this working I've attempted the following: Restarting the router Updating the 5Ghz wi-fi password and using that to connect Moving as close to the router as possible to ensure that the signal isn't being blocked Attempting to connect with multiple devices None of these have worked.   The 2.4Ghz wireless connection still works fine, so I know that it's not a case of the internet completely dropping out - it's just something with the 5Ghz connection. The router is an Archer VR1600v; looking at other posts here it looks like this issue has happened with others of the same model.   Any assistance would be appreciated. Thank you! ... View more
