I need help to choose hardware for 3g/4g

hi all! sorry for my bad english btw…
i need to find hardware with USB for 3g and 4g (if 4g goes down i need use 3g)
i don’t need WIFI, only lan via UTP cable
my usb modem is Huawei - E3372

what models can i use for this?

U can use any with USB port.
But reccomend with USB power reset.
In this case u do not need to reboot your router if its go down. or physically take out and plug in.
u can create shedule to reboot every nigt at …

thx for answer, now i found this 4 models

  • RB951G-2HnD
    RB951Ui-2HnD
    RB951Ui-2nD (hAP)
    RB750UPr2 (hEX PoE lite)

but i dont know which beter?
in comparison they similar…

RB951G-2HnD → Has Gigabit ports
RB951Ui-2HnD → Has 10/100Mbit ports
RB951Ui-2nD (hAP) → Is smaller and has smaller antennas and less range
RB750UPr2 (hEX PoE lite) → Has no WiFi at all, but outputs PoE power to it’s ports

If you don’t need WiFI, choose the cheapest one
