I have a RUT 950 running the latest RUT9XX_R_00.06.05.3. (which it installed automatically recently)
The router is connecting to the internet via 4G.
It works fine but then after a period, normally a day, it stops communicating with the Internet, so devices report no internet connectivity.
It remains connected to the 4G system, the web admin still works and everything looks good but no traffic is going out over the connection.
A software reboot via the web admin does not resolve the problem. It boots up, connects to the 4G network but the connection shows no traffic.
A power off/on DOES resolve it and it works fine again for a time before the problem reappears.
I have a friend who has the same router, same 4G SIM supplier and same Firmware is having exactly the same problem.
I am thinking that the recent firmware update may be the problem as it has been working fine for years. A while ago I manually updated the firmware and set it to do automatic updates (FOTA) so now it is always using the latest firmware.
I would appreciate any ideas on what the problem is or why the latest firmware would cause this.
