Hello,

This is not fully Swisscom related, but my problem probably applies to all ISPs using Swisscom BBCS (Wingo, Teleboy, or green.ch in my case)

I would like to use my Fritz!Box 5530 OE XGS-PON, with the corresponding SFP module, on a green.ch FTTH connection I just subscribed to. They gave me a TPlink HB210 Pro + a Huawei ONT. I would like to use my Fritzbox with the sfp module instead of those 2 devices.

But I can't get it to work. Here is what I observe:
- The devices provided by Green.ch works as expected
- When I connect my Fritzbox, in the setup wizard, it correctly detects that I am with green:

(it got automatically selected, I did not choose Green.ch DHCP FTTH myself).

- But then, it tells me that the router needs to be authorized by green.ch:

I called green.ch support, who told me that no authorized or configuration was required to use another router. I also showed them the swisscom BBCS routers link: https://www.swisscom.ch/dam/swisscom/en/ws/documents/E_BBCS-Documents/e_bbcs_supporting-documentproved-equipment.pdf (my Fritz!Box 5530 XGS-PON is in this list) and they confirmed that I could rely on that list. I can enter an Installation ID, but I couldn't find if I need one and if I do, what it is.

- Then, I have no connection at all on the Fritz!Box. I cannot finish the wizard as it can't connect.

I tried the following:
- Switching to "green.ch" instead of "green.ch DHCP FTTH" option. I can enter more settings in that case, like login infos. I guess (but I'm not sure) that this option is for PPoE internet, and not DHCP. I am assuming the automatic detection was right. I have no better result in that case.
- Switching to "other provider". Same problem. I tried to set "VLAN 10" as some people here mentionned it. It made no difference.
At each point of the process, I tried to connect to http://swisscom.ch/start, without success.
My questions would be the following:
1. Do you have a method to connect my Fritz!Box 5530 to green.ch internet?
2. Do you have informations about other Swisscom BBCS ISPs? (Wingo, Teleboy…)
3. Do you know why the Fritz!Box GUI tells me registration is necessary, and green.ch support tells the contrary?
4. Do you know other settings in the Fritz!Box that I should be trying ?

Thanks in advance for your help, Have a nice da
