I bought a new Archer M200 router by Tp-Link. I wanted to flash it with OpenWrt since I need OpenVPN client functionality but I haven't been able to do it. I followed the tutorial published here (https://openwrt.org/toh/tp-link/archer_mr200) to the letter. The firewall is disabled (the whole thing), IPs are properly set. I use tftpd64, but the server won't even detect the OpenWRT firmware file - the directory path is set but it won't show in the tftpd64 interface.
Running wireshark should show you what your router is actually trying to fetch - and/or if it succeeds doing so. Putting a simple unmanaged switch between your computer running the tftpd and the router can increase your odds of hitting the right timing.

Thanks. I use WireShark quite often, but it never occured to me to use it in this context 
I guess the problem is with the router version since it's V6 and OpenWRT supports only V5 to my knownledge.
