TP Link MR6400 NO SIM Detected
Dear All ,
We purchased TL-MR6400 v4 in the month of Oct 2019 from Amazon. It was working fine since last week . Now it has stopped working and unable to detect SIM.Same SIM is working fine in my WiFi dongal . Tried different SIM but no luck
I tried factory reset . Tried upgrading the firmware but no luck . Is this a hardware issue ? Both log and SS attached . Please help
