Archer C6

I would go for the Cudy because of the warnings on top of https://openwrt.org/toh/tp-link/archer_c6_v3, all the Cudys are easy to flash and recover.

Most routers, AP and modems have different version (v1,v2,v,3,etc.)For example if I buy an TP-Link Archer C6, and got v2 or v3 its ok but if they ship a v4 I can't use it because it doesn't supported.Is there another way of adding WiFi support to my setup? Expect buying an AP

I have a C6 V4 and a C6 V3.20, I'm not able to create the mesh network unfortunately, this is the shame TP-Link. I have no option to change the V3.20 to a satellite router, so it does not work at all. It's simple to update the firmware and add this option, and the worst thing is that in V4 dashboard
