Hey small problem, recently my tplink modem refused to detect any sim card (and yet it previously would) and any attempt to upgrade the firmware results into connection reset screen. What can I do?

Hi, you can try to factory reset it by press the reset button on the back for 10 seconds until the light change. After that, log in to the management page with another device/browser. Re-insert the SIM card, put the SIM card into a cellphone and make sure it is working.

 

What's the firmware version of your router?  Is there any special thing happened before it stops working?
