What do you mean use 5G? Does that mean I should only create internal 5G network and not 2G network? Or does it mean only connect to 5G external network?
Is there a way to find out why it disconnected? Could it be the external network at this hotel that is having a problem? I thought no, because when the problem happens the internal networks go down also, and I have to wait for a minute to reconnect to the router.
Is 4.2 available to the public? My router says it is up to date with 4.1 when I check the firmware version.
