Archer C6 V3.20 EU going back to stock firmware

The router's wifi is turned off, it is like that since I flashed the firmware.

A (beta) release version exists for the C6v3. Run it instead of snapshot, especially since it includes LuCI. Download this file to your PC then push it to the router with scp, log into the router and install it with sysupgrade on the CLI.

You need to flash the gui first. No tftp without UART on this device.

Follow what i say..
Use vi text editor
On the ssh screen, type

vi /etc/config/network

config interface 'wan' 
  option device 'wan'
  option proto 'pppoe' 
  option username 'xxxxxxx'
  option password 'xxxxxxx'
  option ipv6 'auto' 

:wq

Replace the xxxxxxx with username/pw

Then restart

Then check if you have internet.

opkg update
opkg install luci

How do i push it? Sorry, I am still learning in this domain and I wanted some more features on the router but I ended up nearly "bricking" it.

Too complicated for a starter.

actually, it's the easiest method, for a starter.

instead of using vi he can use Wincp's text editor. The method mentioned in this post.

Windows has CLI versions of ssh and scp. After downloading the file, connect your PC Ethernet to the OpenWrt router instead of the Internet. Open a Command Prompt and cd to your Downloads directory. In the Windows CLI:
scp filename root@192.168.1.1:/tmp
After it copies, ssh to the router and run this:
sysupgrade /tmp/filename
Note you can type /tmp/openwrt then hit the tab key and it will complete the name for you.
The sysupgrade will kick you off of ssh while the router flashes and reboots. After it fully reboots, confirm that the network is still connected then open your web browser to 192.168.1.1 for the GUI.

and do this while the only cable connected to the router is Ethernet from the computer to LAN1.

GUYS, YOU ARE THE BEST, I installed it and now I am connect to internet with the router set on PPPoE. Thank U SO, SO MUCH!!!!


I will stay on OPENWRT, it's much better than the TPLINk one, I almost shit my pants during the install, but I am so happy now.

FANTASTIC! I know this experience felt awkward but I would strongly encourage you to stick with OpenWrt because it will unlock a lot of very cool features not available with the original vendor firmware. Also as you have seen from the above the OpenWrt community is a really cool and friendly one. The combined expertise is very impressive.

Does OpenWRT has "Bluetooth coexistence"? I am coming from ASUS Routers and they had it, I couldn't find the setting in the TP-LINK default firmware. I have bluetooth mouse and headphones, and sometimes it lags when one wifi device is downloading something.

Did it have micro wave oven coexistence too?
Same frequency...

Bluetooth coexistence only applies to devices that have wlan and bt radios in the same device (actually on the same combi-card), the typical wifi router does not (wlan only, yes there are exceptions). As this is usually implemented in the wireless drivers of these wlan/ bt combi-cards, the feature is available on OpenWrt as well - but rarely useful.
