When I connect my AR750 to USB LTE module, it keeps rebooting the router after a few minutes. I am guessing it’s because external usb LTE module drawing too much power? Is there any way I could provide AR750 enough power for LTE module?
“I am using PCI-e LTE module with an USB adapter.”
If the LTE modem module is pulling more than 500mA from the usb port then you won’t be able to use it with the router, and you should get a usb lte stick instead.
You could try using a larger usb power brick, more than 2A just to try, but i don’t think.
I fixed this by using USB Y cable. There is an additional port for me to pipe-in power for my LTE modem
