Moving from ADSL to FTTP - BT-HH5a with 23.05.4

I am hoping to move my existing BT-HH5a onto an OpenReach FTTP ONT connection.
I hope that someone could give me a hand?
At the "cabling" level, I understand that I need to connect the HH's Red WAN port to the Yellow "port" on the ONT. Correct?

Now the difficult bit! How to I configure the OpenWRT via LUCi? Trawling this site for clues, I find this: Overview of the BT HH5a. About half-way down, is the sub-heading "ADSL/VDSL Configuration Examples", sub-heading: "United Kingdom - Quick Setup with LuC". There I find these instructions...

 For Full Fibre (FTTH/FTTP):

    On OpenWRT 23. Go to LuCI β†’ Network β†’ Interfaces.
    You can delete DSL interface
    Add new interface β†’ Name=wan ~ Protocol=PPPoE ~ Device=use the free-text box at the bottom of the list to enter `wan.n` where n is the VLAN number
    Create interface, only then you can add the credentials
    Get PAP/CHAP username and PAP/CHAP password from ISP
    In Firewall Settings, Assign firewall-zone to wan

Can you un-pack them for me?

  1. I don't seem to have a DSL Interface. But I do have a dsl0 device? Is that the target of this instruction?
  2. Do I need to "... delete dsl0 device"? Or is it safe to leave so that I can roll-back?
  3. On the "Add new interface" line, please expand on "enter wan.n where n is the VLAN number" How do I find the required VLAN number?

Those instructions have a lot of redundant steps it seems.

All you should really need to do is go to the 'wan' interface and change it from dsl0 to 'wan' and that's it. No other change needed.

…and to keep in mind that the bthub5 is quite dated, it's routing speed is limited to around 100 MBit/s, give or take (~85 MBit/s without software flow-offloading, maybe around 120 MBit/s with software flow-offloading). If your switch to ftth comes with a WAN speed increase, this router might not be able to keep up anymore.

This is a very cool device for VDSL connections, although already very much with the back to wall at the faster end of these (plain vectoring, profile 17b - the modem can't handle super-vectoring, profile 35b). For anything faster than this (~100/40 MBit/s), it does show its age (it was originally designed with 50/10 MBit/s in mind) and simply can't keep up anymore.

Yes instead of having the pppoe driver connected to the internal DSL modem it will be attached to the external Ethernet port instead. The DSL related configuration sections can stay, of course they won't do anything without a DSL line attached. If you need a VLAN tag on wan use for example wan.35 rather than wan to tag the packets 35. The ISP should tell you if VLAN tags are needed.

Sorry about this... I'm not very bright you see! This is what I understand from your advice:


Then, once in "edit mode", this is what I see. No "wan's or "dsl0's":

What am I not understanding?

Sorry that I can't keep up with you experts... but I'm trying :crazy_face:

Change the protocol from pppoATM to pppoe and different options will be displayed.

If you are still using this router for DSL and don't have FTTP yet you should save the configuration in a file (under System- backup) before trying any other settings so you can go back.

Ah.... Thank you.
Gota go now. But I'll check over the weekend and report back.

Once again. Thank you, M.
