OT ish - but does relate to screwfix.

Presumably you're on plusnet?

There's an issue where the supplied router doesn't like the "large" DNS records that screfix use (multiple CDN servers with unwieldy names)

If you can change your devices to not use the router as DNS resolver, should work, e.g.

go direct to plusnet servers

or google

or cloudflare

or quad9

Note that you can set these up ON THE ROUTER as part of its DHCP config..

You don't need to do it on all your devices. They will pick it up via DHCP from the router

Correct.

Have done that on the phone settings and it works fine confirming the diagnosis.

Unfortunately I don't seen to be able to make changes at the router level as I have a plusnet Hub 1 router.

Not with a plusnet Hub 1 router it seems :-(

Buy a decent router. Something like a Draytek will work with any ISP.

What if you have an ONT?

How does one get the ONT and your new router talkiing to each other?

S.

My Draytek (2866) has a WAN Ethernet port. Short cable from there to the ONT. Job done.

(I can see ir from here)

Isn't that just the fibre equivalent of a cable modem?

I am on Virgin and it took just one setting change to switch their router/modem into modem mode - so my Draytek router just uses an ethernet input for its WAN connection and the Virgin modem just passes whatever it's given, in either direction.

It also has the advantage that if I change ISPs, I'll just have to change the modem unit or switch the router to use its VDSL port and all the internal network settings, firewall, etc. will stay the same.

plug ethernet between ONT and WAN port of router, configure PPPoE on router ...

which requires you to know the credentials of the PPPoE on which is something teh ISP is not going to give you easily.....

They'll certainly give you your username/pass for PPPoE, the rest should be autodiscovery all the way.

maybe you're confusing the ease of PPPoE with the difficulty of getting SIP/RTP credentials for VoIP out of most ISPs?

and that too as my landline comes out of the current Vodafone router..... so How do I "port" the currentl landline port on the vodafone router to the 3rd party router (assume it has a landline POTS port on it.

S.

But this discussion wasn't really about VoIP, it was about replacing a dodgy plusnet xDSL router with your own, to get working DNS

For voda, ask voda ...

Ditto here. FTTP and a Draytek (turns round to look) Vigor 2762

Best domestic router Ive possessed. As good as my Cisco SOHO router but doesnt get red hot in use

Not cheap, but worth every penny

Amy router that says its suitable for 'cable' will have an ethernet port that can be configured to be on the far side of the NAT and firewall and capable of running PPOE

Seems to me this kind of issue is Screwfixs to fix, as it will be they who will lose business by the problem. Brian
