Hi,
I recently bought a TP-link router from a scrap dealer. He upgrades systems for small companies and scraps the old hardware at yard sales.
The one I got was Tp-Link Archer C6 US v2.0.
I'm attaching the photos of the Pcb here to confirm whether this is supported by openwrt. I did refer the documentation at https://openwrt.org/toh/tp-link/archer_c6_v2 but the one attached there is for EU version. Mines a US version and bit different looking.
Kindly take a look. Thank you for reading
