I am using an AR-GL750S-EXT. I have a USB hub that has 3 cellular hotspots connected to it. I plugged it into the USB port in the back of the router. It connected to one of the hotspots. Is there any functionality that allows it to connect to more than one tethered hotspots?
I never try multiple tethering but here is what you can do.
First connect your hotspots, usb hub and AR750s.
Then in AR750S you will find eth1, eth2 and eth3 etc. Every eth should be one of the tethering.
You can set up one tethering using the UI. Then edit /etc/config/network and add other tethering manually.
Pls adjust the “metric” option which a small number means priority.
