Hey guys!
Router: 951Ui-2HnD
Modem: E3372h-153 (hi-link firmware)
Note: I have 2 the same devices (951Ui-2HnD) and I have the same problem on both of it.
The Problem
When I connect a modem to USB port in a router I can see interface LTE and interface gets IP from DHCP correctly. But when I try to use it then LTE interface starts to “blink” - hide/show in an infinite loop.
Also, I have bought USB Power Injector (https://www.balticnetworks.com/media/catalog/product/cache/1/image/512x512/9df78eab33525d08d6e5fb8d27136e95/5/v/5vusb.jpg). It didn’t help me.
Also again, I have another USB LTE Modem (Wi-Fi Modem YOTA 4G LTE) and it has the same behavior.
Both of modems included to supported LTE USB-modems list (https://wiki.mikrotik.com/wiki/Supported_Hardware#4G_LTE_cards_and_modems)
I don’t know how can I fix it. Might, have anybody already fixed the same error and can help me?
P.S. Both of modems work correctly in PC or MacBook.
