ER605 Router help request
Greetings to all and best regards from Rome, Italy.
I have a small office in an area outside Rome not covered by Internet fiber or cable connections.
Outside the building I had installed three Nokia Fastmile 4G LTE antennas each with three SIM cards from three different Italian mobile operators.
Each antenna operates in bridge mode and can be reached via a DHCP server.
Each antenna has the same IP configuration (192.168.0.1 and DHCP IP range from 192.168.0.50 onwards).
I purchased a TP-Link ER605 and activated all the WAN ports in Dynamic IP mode. Everything works very well and the bandwidth demands of the whole office have improved greatly. But now I have two problems and I hope someone can help me solve them.
First one: I may periodically need to enter into the respective GUIs of the Nokia antennas to do maintenance.
With the default ER605 IP class (192.168.0.1) there is no way to enter the antennas. I tried changing the IP class of the LAN to 192.168.2.1 and in this mode I can manage the access into one or two but never all three. Of course I assume it depends on which WAN link you are using in that time...
Is there a way to access the three antennas while maintaining the best connection performance on the ER605 switch?
Second one:
I noticed that if one of the three router antennas (any one) loses connection and respective WAN go down, all the computers in the office no longer have a connection even if the other WANs are active. How is it possible ? Shouldn't they keep the connection automatically FROM ACTIVE WAN?
If I activate the "Link Backup" function, the line designated for backup is no longer used... I would like to use all three connections and be able to continue browsing if one or two fall down... which would seem more obvious to me but I I am not able.
What am I doing wrong or where should I check if I have set something wrong?
I apologize if I was talkative but I wanted to explain myself well and I apologize in advance for my terrible English.
Thanks in advance for anyone who wants to help me, best regards.
