Hi, I have a RUTX50 5G router on the Telstra network in Australia. I am in a strong 5G coverage area however the router will not connect to the network and stays on 4G. I have tried 4G+5G, 5G Only and Auto in the settings it makes no difference. I have tried multiple locations and multiple SIM cards which I have tested in another 5G device and they connect fine.
The other issue I have is I need to connect this to a UniFi Security Gateway (USG4) which already has 4G Teltonika devices connected via IPSec to provide a site-site VPN. Both endpoints have a public IP, and the VPN establishes fine the first time. If the connection drops however, the VPN will fail to reconnect. This happens even if the IP of the RUTX50 remains the same. The only way I can get it to reconnect is to delete the VPN connection and create it again but obviously this is not sustainable.
Appreciate any help on the two issues above.
