How to choose a stable router for 3G USB modem?

Question

mobile connection

Hello.
Recommend some simple 4-port WiFi router with support for 3G modems. He needs to not get hung up.
It would seem that I put OpenWRT on any and forgot, but it wasn’t there, I already suffered with TP-Link, then the memory ends and the modem stops being detected, then the hardware ports are buggy, then it just freezes :(
The main Wishlist is that it doesn’t freeze, will work standalone.No bells and whistles needed.

Look at the second generation ZyXEL Keenetic.
