What is the installation method for C6? Do you have to open the router or a flash from the firmware upgrade page is enough? I tried searching openwrt forum but i am unable to find anything about archer c6I bought it from Amazon as it had quicker delivery and cheaper price and yes I got the EU v2 its been working fine ...I've tested wan side bandwidth with iperf3 and PC as server I got 993mbps from it and on my phone 5g WiFi speed is showing as 433mbps
