Frequent Connection Loss & Poor Internet Speed
Hi TP-Link Support,
I am using TP-Link Archer MR400 AC1200 3G/4G router with Airtel SIM card.
Earlier, I was getting 50-60Mbps speed but from past 20 days, I am getting only 100-200Kbps speed.
Also, the router frequently disconnects from the internet. After 2-5 minutes, I need to restart my router to reconnect with the internet.
While, at the same Location and same SIM card, I am getting good speed in mobile and my other Hotspot device.
When I try to upgrade the firmware, it showing "Internet is unavailable", I did a manual upgrade from here- https://www.tp-link.com/in/support/download/archer-mr400/v2/
Can you help me to fix this?
