I bought an TP-Link Archer C50 (EU) V6.0 router. Since there is currently no dedicated firmware version (device seems to be very recent), I went with the instructions for v5 as described here: https://openwrt.org/toh/tp-link/archer-c50#v4_and_v5_instructions
I decided to manually build the firmware (dd if=...).
Flashing via TFTP succeeded. However, after logging in I am only able to see the 2.4 Ghz device.
I've added some debugging output below. Any idea if and how I can get the 5 Ghz interface running?
Some debugging output:
