TL-MR6400 disconnected many times per day
Hardware Version: V4
Firmware Version: 1.10.0 0.9.1 v0001.0 Build 190521 Rel.38696n
My Internet left many times per day on my TL-MR6400 v4, just bought....
When the problem happened, all lights of the modem are on.
I saw many users have same problem with different models of 4G modem. I saw answers given by tp-link staff.
So I create a manual apn profile, set manual dns servers on dhcp menu (18.104.22.168 and 22.214.171.124), check 4G connection with my phone but the problem is persistent.
Nothing appears in the system log, all steps indicate "pass" in diagnostic menu...
So I need to reboot the modem and it works again. So please help
