Review on WiFi router TP-LINK TL-MR3020, white by Ninad Shinde

Purchased to use wi-fi in the car through an unlocked 4G modem ZTE MF823 (M100-3 from Megafon). The modem connects successfully, but if you want to change the SIM card, the router will not be able to send an AT command (CGDCONT) to the modem normally to set the desired APN, and this will have to be done manually through a connection to a computer / laptop. In addition, if the AUTODIAL setting is not set in the modem or the AUTODIAL setting is lost, then with this router the modem can successfully find a mobile network, but will not connect to it, because the router does not know what to say CONNECT to the modem. However, if you know how to do it all by hand, then the device works great and does its job.
