Hi Folks,
N00b to extreme levels here, so I apologise in advance. I watched about 20 videos on openwrt everyone flashes and then, goes to the web interface sets a password. Everything is done. I've flashed to my Archer C6.. everything was a breeze.. web interface came up. Everything is fine, but no internet at all.. not on LAN, not on Wifi.. followed the guides about changing the IP of the router. No change.. everything looks exactly as it should but there is just no internet. Any suggestions, is there something Im missing?
Use ssh to connect to the device.
Please copy the output of the following commands and post it here using the "Preformatted text </> " button:

How is your router connected to the internet? Is there another upstream router? A modem perhaps?

Like this the router is trying to get settings from a dhcp server on wan port. There doesn't seem to be anything connected there, or a different protocol needs to be used (like pppoe). So as @eduperez asked already, it would help to know what other equipment is there and how do you connect to the internet.

Thanks for the replies folks, There are two things that isp provider put in .. a 'Gpon terminal' which looks like this https://www.aliexpress.com/i/33006573188.html
And another unmarked box. Unfortunately cant make out what it is..
Is the other box a router?
Doesn't appear to be. Has one blue cable, no lights. Literally nothing on the box at all.
Googling around it appears to be a Termination Point (TP)
Can you make a diagram how do these devices connect to each other? I suppose they were working somehow before you decided to buy the Archer.
Everything was put in by the isp.. including the archer.. this would appear to be the setup. 
Alright, so the blue cable from the ONT must go to the wan port of the Archer. However it is not clear if dhcp, pppoe or some other protocol needs to be used. So you'd better call your ISP and ask.
That is correct, it does indeed go from the ONT to the wan port of the Archer. Okay I will call them and find out. I really appreciate all your help. Shall keep you posted.

My two cents:
-
If you just have one ethernet Port, it does not make sense to bridge eth0.x on the LAN interface. Your LAN will have to be wireless only.
-
Your ISP will probably require you to configure the WAN interface in some specific way, probably using PPPoE.

ISP finally got back to me, the router's MAC address is apparently mapped to the ONT. So they say it should 'just work'
If it helps I have the modem's IP address
did u set ur wlan radio ssid have checked lan or wan try first lan hope its that 
goodluck
This doesn't answer my question exactly, but I suspect that dhcp should work on the wan interface.
