Sky Fibre & Unifi Dream Machine

KGx — Thu, 29 Aug 2024 15:14:34 GMT

Hi all,

Hoping that I can get some help as I'm loosing my hair with this issue.

Been using Dream Machine Pro for the last 2 & half years with Sky Broadband (copper w/ Draytek) & no issues.

Switched over to Fibre over a month ago & plugged from the OpenReach modem straight into the Dream Machine & everything is working fine, until 12:55pm today where it's showing that there is no Internet available.

I've plugged in a Sky Broadband Hub & that's working fine, restarted the UDMP no dice, messed around with any DHCP settings that I've found online & nothing.

So I'm hoping that someone by the grace of god on here has got some sort of idea or help!

Thanks for listening to the rant!

@KGx

Settings should be something like this except don't enable vlanid and don't enter a value

@KGx

Could you select slaac for ipv6 connection

Re: Sky Fibre & Unifi Dream Machine

Done & still no luck, the clone mac address I put in was the one of the broadband hub that works, would that make any difference or no?

@KGx

Could you re enable vlanid and remove 101 then disable

Also theres no requirement for mac cloning so try deleting the mac and untick it

@cookiemonsteruk could this be a MAP-T issue with Sky misidentifying the UDM as being compliant when it isnt? Would that explain the connection working then not as, if you recall, we were told that third party routers would be switched if they "supported" MAP-T? As otherwise everything looks correct.

Sorry @cookiemonsteruk - the last upload didn't work, this should show current settngs

@cookiemonsteruk @Chrisee - Not sure if this helps you on your troubleshooting, but i've just done the following

ONT Box -> Sky Hub -> UDMP

That has worked now & gave me a connection, it's not brilliant & i'm loosing about 400mbp down, i then tried to just remove the Hub out of it and it broke again.

Really apprecaite the help but have no idea what is happening with it.

@KGx

See where it says prefix delegation could you put a / in front ie /56 and try directly connected to the ont

@KGx to explain my post which is a guess as your connection worked then stopped which implies a config change some where broke it. We know Sky are switching customers to this method to make IP4 addresses stretch further @cookiemonsteruk and myself attended a presentation a few weeks back when Sky told us that third party routers would be switched at some point. The older black Sky hubs dont support the system so the servers ignore them but it applies to the newer white SR213 hubs.

i am not very knowlegable about your UDM but this support thread https://community.ui.com/questions/Feature-RequestMAP-T-MAP-E-carrier-grade-NAT/4003b1d9-6bd4-4ef7-903f-d551b5feb7bd?page=2 implies it still doesnt support MAP-T 8 years after the intial request.

Unfortunatly it doesn't let me do that

@Chrisee - Thanks for the information on this, so from a customer stand point, do you know what the next steps are on this?

Obviously it's not ideal for customers to be experiencing it, nor having to daisy chain through a hub to get the network back working is a terrible thing to have to do.

Re: Sky Fibre & Unifi Dream Machine

Chrisee — Thu, 29 Aug 2024 16:55:14 GMT

@KGx I repeat my post is a guess. However as Superusers we have access to Sky staff - hence the briefing I mentioned - I will check if such a switch was made this morning and if the technical contact think this is possible theory.

Sky's official position is they don't support third party routers however they know a small minority of customers choose to do so and the SU group are encouraged to offer support. However if a particular model router works or not is not something officially they care about. Ubquiti kit is complex and not widely used in my experience.

@Chrisee - Thank you for that info, totally get the 'lack of care' that Sky have for us users at the moment, after spending 2 hours on the phones this afternoon with the technical team & them just dismissing every smidge of an issue & stating that "sky router is better than anything else ever".

It's not a great time at all, I appreaicate you being willing to reach out to your contacts & i'll await further commucation from you on this.

Long shot but if that's something that has been switched on, surely it could be switched off for certain users?
