Connect Sky router to full fibre line?

[Cat1967]

Hi,

Bit of an odd question, but I am currently on a trial where I have a full fibre line (from Talk Talk) coming into my house that I don't yet have to pay for - they said for at least 6 months and probably longer, I don't have to pay.  It's in parallel with my Sky FTTC circuit.

I am wondering - what would happen if I plugged my Sky router into the full fibre line optical converter output?

At the moment I am a full Sky customer - Broadband / Talk / TV incluing 3 separate mini boxes Sky Q.

I am sure it won't work fully but would anything work at all?  I am thinking it will either be:

- Nothing works at all.

- Basic internet works but TV and phone line has problems.

- Everything except the landline phone # works.

Also would I break anything by trying this out?

It won't work .

sky uses dhcp option 61/ipoe to authenticate with its servers and talk will use pppoe . The authentication strings will be embedded onto their respective routers and aren't interchangeable

TalkTalk uses DHCP IPoE without the requirement for DHCP Option 61.

@Cat1967 

It won't break the router if you plug it into the TalkTalk system and ONT but it likely won't work.

I just read up on that "automated authentication without need for username or password" using dhcp/ipoe. That surprised me

@cookiemonsteruk & @Cat1967 

The DHCP IPoE isn't too different from DHCP Option 61 over IPoE and I'm wondering whether the TalkTalk system may just ignore the DHCP Option 61 field and work. 😉

Thinking exactly the same thing 🤔

It would have to be the SR203 Sky Hub for any chance of working and you plug port 4 LAN/WAN into ONT.

An ER115 will work.

I used a spare one I had knocking around when my SR203 died and managed to get the full speed on Ultrafast Plus. Just need to set it WANoE and plug port 2 into the ONT. The only caveat is it get a bit hot if there is a lot of downloading going on.

OK - how do I know which Sky router I actually have then?

@Cat1967 

SR102 on the left, Sky Q ER110/ER115 middle and SR203 on the right.
