Hello, friend!
I have an issue with by B715s-23c modem: I lose the network 4G connection once or twice a day and the modem won't reconnect by itself.
It seems the only way to reconnect is to restart the modem either by unplugging it or restarting the procedure in the advanced system settings. Turning mobile data off/on won't work.
The network type is set to 4G only, the band is automatic and the provider is set manually.
It could be the provider kicking me off the network for being on it for too long, but then I would like to know why restarting the modem allows me to reconnect immediately. What changes?
The screenshot shows the interface when it disconnects.
This is getting frustrating.
Thanks.

Hello, friend!


According to the b715s WebUI, the device network is lost.

Consumer products usually use the home network. Therefore, device network loss needs to be detected based on the response parameters of the ISP network.


Generally, when a wireless terminal is disconnected from the network, it automatically initiates network search and registration again and the network connection is successful. If the network rejects the registration and access of the wireless terminal, capture packets to check the network connection.


According to historical experience, if the ISP network rejects the access request of a wireless terminal and returns a special rejection cause value to the terminal, the wireless terminal waits for 12 hours and then re-initiates a registration request according to the cause value described in the protocol. If the wireless terminal is manually restarted, the duration is not limited to 12 hours.


Thanks!
