I have Arris TG2472 gateway with both of the 2.4 GHz and 5 GHz SSID's hidden. One laptop, from work, an HP EliteBook 1030 G4 Windows 1909 will randomly disconnect from 5 GHz WiFi and it takes down a...
I don't know why your 5 GHz network keeps dropping. It could be your workstation but it'd have to be doing something hogging lots of bandwidth.
I can only recommend a wired connection and since you don't have an Ethernet NIC, you could probably get a USB NIC...technically a USB to Ethernet Adapter...look for gigabit speed although you probably won't get gigabit via USB.
Oh I see, and do have an old repeater for the garage.
Well, it happened again need a way to pinpoint that. I think is this laptop, it's connected to remote desktop and corporate VPN, not sure if still drops when only on WiFi though.
I do have one USB NIC and might get a few more, but the Arris TG2472 is a little far from the laptop will need a long cable. I will have to look and see if it supports gigabit speed, but hope that is not needed.
