I have bundled a E3372s HiLink modem with RB951-2HnD, every thing is ok and work normaly, but after a while LTE modem not responding to ping or any network request. LTE interface is shown in interface lists but DHCP-Client does not have any IP from LTE modem and the old ip is gone. After a reboot of router board every thing is ok again.
This problem is periodic and repeating periodically.
How can I do?
