The C80 support page is here where you will find the user and quick setup guides.

Hi,

The VLAN and IGMP settings are in a different menu. Refer to the screenshot below.

I suggest you first setup the C80 for regular Internet access (first section in TIM's "FTTH Connection" guide) and after you get that working you can further experiment whether you can also make the "multicast mode" (second section) work.

  @woozle  thanks, I can see they are in a different menu, this is my conf now, still no internet.
Voip VLAN ID and IPTV VLAN id are made up, you can't leave it to 0..

  @alfredopacino 

Can you please post the log of one connection attempt?

To do that it would be best if you did it like this:

- go to "Advanced -> Network -> Internet" and change the "Connection Mode" to "Manual" and then [Save] it
- go to "Advanced -> System -> System Log" and click on "Clear All" to remove old log information
- go back to "Advanced -> Network -> Internet" and click on "Connect"
- go back to "Advanced -> System -> System Log" and either copy and paste the log messages directly from the window (make sure you get everything, may need to scroll down!) or just save the whole log to a file via the [Save To Local] button
 

  @woozle 

this is the log. It might be related to multiple attempts, as I didn't see any entry in the log being printed live. I had to refresh the whole admin panel.

Ok. You can see yourself what's going on here.

The router tirelessly sends out (i.e. transmitts, "TX") commands to the ISP, but it never receives ("RX") anything back from the ISP's side.

The log should begin like in the sample screenshot I posted earlier. The router at home sends a "PADI" and the ISP should reply with a "PADO". But this is not happening in your case.

Does the ONT you've got from the ISP have any status LEDs? If yes, what do they indicate? 

Furthermore, in the "Network Map" of the Archer C80 click on the pictogram of the "Archer C80", scroll down to the bottom of that page and verify the Ethernet Status shows something connected to the "Internet" port. (should show "1000Mbps Full Duplex")
 

By the way, is this a brand new FTTH Internet connection that you are trying to use for the first time now? Or did this FTTH connection work fine previously with another router model?

  @woozle thanks for the help. Here the info you have asked, it seems I have to have a call with my ISP?

1. The ONT is a ZTE ZXHN F6005. 3 leds: LON is off, PON always blinking, LAN on

2. Ethernet Status correctly shows a 1000Mbps Full Duplex

3. It is a brand new connection

  @woozle thanks. The ISP has sent a guy to fix it in my flat. Apparently my fiber slot wasn't even properly set up in the box at ground floor of the building.
