Delta

We have no preset for Delta. That is not an oversight, and it is not a complaint about the provider: we only fill in settings we are sure of, and we do not have Delta's. So there is no "Delta" entry anywhere in the tool, and it is better that we fill in nothing than that we guess and cost you an evening on a connection that never comes up.

This chapter is therefore not about Delta as such, but about the route to your own settings, with Delta as the example. It works the same way for any other provider that is not in the list.

Leave the choice on Own settings

The provider list sits at the top of the WAN / internet section. Pick Own settings and nothing happens: every field stays as it is and you fill the uplink in by hand. Do not pick another provider's preset because it looks close enough. A wrong VLAN number produces exactly the same picture as a broken cable.

Three things you need to know

A working uplink does not need much, but it does need this:

1. Do you get your address by DHCP, or do you log in with PPPoE? That decides whether credentials are involved.
2. Is there a VLAN number on the WAN port? If so, which one. Leaving the field empty means no VLAN.
3. For PPPoE: username and password. Usually in the letter or mail that came with your line, or in the customer portal.

While you are asking, ask whether your line gets IPv6 and by which method, and whether TV and telephony run over VLANs of their own. That saves a second phone call.

How to find the VLAN id

• Ask your provider. Support knows this, or the installation guide of the device you have now names it.
• Look in the router that is there now. Provider routers often show the VLAN with the WAN or internet settings.
• If no VLAN number is mentioned anywhere, there usually is none. Start without one.

Do not sit and try numbers until one works. You can, but it costs hours, and afterwards you still do not know whether you found the right number or got lucky.

What to try first

If you genuinely do not know, this is the order with the best odds:

1. DHCP without a VLAN. Set the type to DHCP and leave the VLAN field empty. If you get an address, you are done.
2. DHCP with the VLAN number your provider names. Enter it under VLAN id on the WAN port. The configurator then creates a VLAN interface on your WAN port and hangs the DHCP client on it instead of on the bare port.
3. PPPoE, with your username and password, and with the same VLAN number if there is one. Leave the MTU field empty and leave clamp TCP MSS on.

Each step is a new script. You do not have to reset the device every time: you can change the uplink in WinBox and paste the final script once you know what works. See Using the script.

The provider's box

If there is a modem or router from your provider, ask whether it can go into bridge mode. If it keeps routing, you are behind two routers: internet usually works, but port forwarding, a VPN into your house and plenty of consoles do not. See Moving off a provider router.

IPv6, TV and a fixed address

Without a preset, IPv6 is not filled in for you. In the IPv6 section you choose the method yourself; prefix delegation is the ordinary case and the requested length defaults to /56. Ask your provider which block you get and set the length to match.

If your provider delivers TV over multicast, turn IPTV on in the WAN section and turn on IGMP snooping on the bridge. If TV has a VLAN of its own, add it as a second uplink. See Recipe: IPTV.

If you have a fixed address or block, set the type to Static IP address and fill in address, gateway and DNS exactly as your provider gave them to you.

Checking that it works

1. For DHCP: /ip dhcp-client print should read bound, on the right interface. With a VLAN that is the VLAN interface.
2. For PPPoE: /interface pppoe-client print should say running: yes.
3. /ip address print and /ip route print show whether you have an address and a default route.
4. If it does not work, /log print is where PPPoE says why.

Help us add a preset

Once you have it working, send us the settings through the feedback form: the provider, DHCP or PPPoE, the VLAN number, the IPv6 prefix length you get, and whether TV and telephony have VLANs of their own. Then we can turn it into a preset, so the next person on Delta does not have to work it out again. What is already planned is on the roadmap.
