Good day. I have a serious problem - I do not know how to return to the stock, original firmware at TP-Link Archer C5 v2. OpenWRT - OpenWrt 18.06.1 r7258-5eb055306f / LuCI openwrt-18.06 branch (git-18.228.31946-f64b152) and does not work with 5ghz WIFI. The reason behind OpenWRT was NordVPN and OpenVPN. However, the integrated 2.4Ghz Wifi is not enough in my home and I bought the Archer C5v2 just for 5ghz antennas. I have MacOS and putty application does not exist. And TftpServer app does not do anything...
Step-by-step how-to for noob?
Or, is there anyone who would make a driver for the use of antennas at 5ghz? OpenWRT is a great alternative to firmware, internet over LAN is faster but 5ghz WIFI is a higher priority for me.
