My device is a TP-Link M7350 v3. I have a data-enabled sim card in it. The device has previously been working but devices connected to it can no longer connect to the internet.
As far as I can tell, it is successfully connecting to the mobile network as the network name is displayed on the device and it also shows good signal strength(bars). However, my other devices (laptop, phone) can no longer access the internet via the device. They successfully connect to the router's network, however, no connection to the internet. The router's display shows data transfers at 0.
I have tried putting the sim in another device and it is working well there. I have tried a different sim in the router and this too is not working leading me to believe it may be an issue with the router. I have also tried reseting the router with no success. I am also unable to access the admin page via the usual links (tplinkmifi.net and 192.168.0.1).
