Review on Wi-Fi router TP-LINK TL-MR6400, black by Momchil Ivanov ᠌

feedback about version V5. I took this router to reserve wired Internet in the office, stuck a SIM card with a megaphone, the tariff "download at any time, 60r / per day (when the main one falls off)". ideal for this task Has pros: seamlessly switches from primary to backup channel, excellent 4g reception Has some cons: in the web interface, do not see messages on the SIM card. there is a message notification, but the message list is empty. firmware ate didn't help. No 5GHz.
