We are testing new modem, RUT955, ver 06.04.5, Mobile (only) connection, Vodafone SIM - Italy,
The Mobile connection randomly drops (usually between 10min 2hours), automatically reconnects in few (<10) seconds (the status and Log pages report "Connected"), but traffic stops: default route disappears, ifconfig lists a 3g-ppp interface.
- 2 LTE antennas are "firmly" connected
- Tested in different sites, same problem (even if on avarage disconnection time changes). RSSI (gsmctl -q) -77dBm
- We use the modem to build IPSEC connection to Main Office. (It works as long as data flow)
When default route is manually re-added, IP packets start flowing again.
