This morning, my router was fine, LTE bars were here.
I powered it OFF, and powered ON. After that, there were only LAN and power icons on the router.
I can access tplinkmodem.net, but :
-Sim card not detected.
-Can’t do a factory reset through tplinkmodem.net : Error code: 20. Nether with the reset button.
-Can’t do a firmware upgrade : “the connection has timed out”.
I tried those reset/upgrade without the sim card, nothing changed.
I tried my sim card on another device, it was working fine.
Please, help me
