My TP-Link ML-MR3020 is constantly rebooting anytime I insert the 4G LTE USB Modem 551L. I have verified that the modem works on computers.

This web pages says the two are compatible:

https://www.tp-link.com/us/support/3g-comp-list.html?model=TL-MR3020

I thought I'd try to reinstall the firmware but the link of the page above doesn't seem to go anywhere useful.

I also thought I'd try a new "3G/4G Modem Bin File" but the link for that on the page above, again, doesn't help.

Can anyone suggest what may be going wrong or how I might trouble shoot these constant reboots?

Also, can anyone provide a link to the current firmware version of the MR3020?

Last, can anyone provide a link to the Modem Bin File for the USB551(4G) modem?

Any help will be appreiciated.
