After we replaced the SIM card from KPN for one from T-Mobile a few weeks ago. Are we having problems with this router. We have the same problem with a different location, just a different Router (RUTXR1) with a T-Mobile Sim now.
Location is a Store, on the Teltonika is a cisco meraki connected with the store equipment. On the cisco we see packet loss. If we disconnect the cisco from Teltonika, the location will no longer have any problems, the Cisco will then switch to its 4G backup. Please help.
