Verizon internet with WE826 and EM7455

Post by Gorus » Wed Nov 06, 2019 12:43 pm

When I connect 1 PC to the WE826, everything works good and I have internet, but if I connect we826 to the mikrotik and configure mikrotik to use we826 as a backup, modem stops working as soon as mikrotik switch clients to the we826. Then I have to send AT!RESET command to the modem and reboot we826 to restore connection, otherwise modem just fails to connect and says "retrying".
I configured NAT between mikrotik and we826 to hide all computers behind 1 IP, but we826 stops working same second when mikrotik routes traffic to it. I started experimenting and decided to send only 32 IPs (probably 10-15 active devices) to the we826 with /27 mask (192.168.5.0-31) and it worked, then I changed it to /26 (192.168.5.0-63) and again it worked, but after I changed it to /25 (192.168.5.0-127)it instantly stops working (DHCP pool 192.168.5.100-192.168.5.254) because there are then probably more than 30 active clients. I'm not sure who is limiting me, Verizon or we826+EM7455, but I tested this 10 times, and I can have around 20 devices using this as a backup, but if I add more, modem gets disconnected and I need to repeat this process again.
After some testing, I configured mikrotik to failover only 5-10 PCs, SBC (Session Border Controller), and domain controller (because of DNS) to the we826 and everything works rock solid without any problems. All computers and phones in the office worked without problems until main connection was restored.
This was acceptable for our client (to have important PCs and phones working when main connection is down), but modem is now disconnecting randomly after 1,2,3 days and then I have to reset power (I'm not on site) OR again send AT!RESET to the modem + reboot the router which is frustrating because I can't do this on my own when main connection is down.
I now configured "Connection Monitor" with "Modem Reconnect" option enabled, but not sure if this is same like AT!RESET + router reboot or I will again have inactive backup connection?
Please let me know if "Modem Reconnect" is proper option or I should use some other feature to restore internet connection when modem disconnects.
