Internet Disconnects When Setting VLAN 10 on R3 (Vodafone Fiber ONT)

[Mohamed87]

I’m using Vodafone Fiber, and the ISP ONT requires VLAN 10.

However, when I configure VLAN 10 on my R3, the internet disconnects completely.

If I leave the VLAN field empty, the internet connects, but it randomly disconnects from time to time.

You're saying the ONT requires VLAN 10, does that mean the ONT is actually set to use 10 for VLAN? If so then you do not need to input this into the R3 as well. 

How often are you disconnecting? When it happens again please grab the logs from Settings prior to rebooting and we can take a look.

Before I created the new Router WAN profile, the internet used to disconnect around 4–5 times per day.

After setting up the new profile, it now only disconnects 1–2 times a day.

When it happens again, I’ll send you the logs before rebooting the router.

You should delete the first profile and for the second then apply it to LAN1 as well and see if that fixes it.

Ton FAI utilises PPPoE et Vlan ID pour contourner leur routeur !

As tu garder la configuration PPPoE sur le R3 ?

- Soit tu utilises le R3 derrière l'ONT avec les informations Vlan 10 et PPPoE (Plus de VOIP)

- Soit tu utilises ton routeur FAI derrière L'ONT et le R3 en DHCP

@Netduma Fraser  C'est le même cas de figue que Turk Telekom ...

 

----- Si tu nous donnes le nom de ton FAI et une photo de ta configuration (ONT-ROUTEUR-R3), je suis sûr que nous pouvons t'aider !😉----

the first profile is 

The first profile is actually the bridge one.

Previously, I had deleted the router and VoIP profiles, and the WAN was disconnecting about 4–5 times a day.

After I restored those profiles and disabled the WAN on the router profile, it now disconnects only 1–2 times a day.

Today was the first day my R3 didn’t restart  due to internet loss, which is great.

However, I had to restart it manually because the Netduma app on my phone stopped responding and showed “Try rebooting.”

When I tried to access the router interface via 192.168.77.1, it wouldn’t load either — the page just wouldn’t open at all.

Even after rebooting, I could access it through the app or the browser.

Eventually, I had to restart it again to get access back.

 

Could you please help me identify what might be causing this issue?
