About two weeks ago my 5 GHz internet suddenly stopped working on my 3 Windows 10 machines (two laptops, one desktop) and also on two Android devices. Prior to that they'd been working for a long time without any issues. However, the 2.4 GHz band continues to work fine.
In one of my Windows 10 machines I tried going into Device Manager -> Network adapters and updating all the drivers, but that didn't change anything.
It isn't because of my location within the house - I've moved the laptops around to various locations and that hasn't fixed anything.
The modem is a Netcomm NF18ACV.
What could cause this to happen? What could be tried to fix it?
