Hi, 

Send me the link for downloading interim firmware for the TL-MR100 IN/v3.8... need to upgrade to TL-MR100(EU)_V3_1.7.0 Build 251121 for testing for testing PCI/EARFCN values and the Cell Locking feature on the TL-MR100 IN v3.8.
 

This type of Cell Locking and manual band selection feature is something I have already used back in 2017 with Mastel 4G routers. During that period, I used Cell Locking to connect to the fastest nearby Jio tower and achieved much better and more stable speeds. It was a very useful and powerful feature, especially in congested network areas.
 

It is really good to see leading brands like TP-Link bringing advanced features such as PCI/EARFCN-based Cell Locking and manual band selection even to entry-level 4G routers like the MR100. 
 

I would also appreciate it if the TP-Link team could consider adding the following features, especially for the Indian variant firmware:

• Built-in Netwatch / Internet Watchdog feature
• Customizable internet check interval and auto reboot timing (example: reboot after 120 seconds of LTE internet failure)
• Automatic WAN port switching in case of 4G failure and WAN failure to 4G switching options
• Option to lock multiple LTE bands and preferred tower combinations

Currently, I am using a separate ESP8266-based auto reboot setup with the MR100 to recover the router whenever internet failure occurs from the ISP side. While it works reliably, the additional hardware setup looks messy and increases complexity. If these features are implemented directly in the router firmware, it would make the setup much cleaner, more reliable, and professional for both home and commercial users.

Thank you.
