Using LAN cables with Full Fibre

sheilajlister — Tue, 30 Jun 2026 19:14:48 GMT

I have signed up for Full Fibre installation and have some questions. I understand that I will need a new kind of router. Will I be able to use LAN cables with this new kind of router? Currently I run a LAN cable to my laptop from the router and a very long LAN cable to the TV so that I do not need the WiFi switched on. (I prefer not to use Wi-Fi.) Currently, if I need to switch the WiFi on and off, I can do that through the Hub Two Manager. Will this all be the same with the Full Fibre router?

Also if I find at some point in the future I need a medical alarm, can this be done at a later date - that is after I will have had Full Fibre installed and have no landline?

Thank you

@sheilajlister Yoiu do not need a different router - the HUB2 is perfectly capable, and is in fact the one used for FTTP..

The only change will be that your Hub will be connected to the 'outside world slightly differently - via the ONT (Optical Network Termination) rather than via your master socket.

As regards medical alarms, these are now (or should be) independent of a 'landline' - they are connected to monitoring stations via a SIM card over the mobile networks.

You may find some information here: https://www.plus.net/help/broadband/full-fibre-faqs/ , but if you need more, we are always ready to help.

BTW - Who said you need a new/different router?

Probably PN as if youve been on ADSL or FTTC long enough you might predate hub 2 although in op case they already mention hub 2

@njay The OP states she already has a HUB2 - which should be on PN's records.

@sheilajlister

Whilst you do not need a new router, you will need another LAN cable to connect the router to the new ONT. This replaces the DSL cable that you currently use.

Good point, @Baldrick1 - I forgot to mention that.

@sheilajlister

You need to make sure any LAN cable being used is Cat5e or better. Any old CAT5 cables you have will limit your Full Fibre to less than 100Mbps. There should at the category number on the outer PVC sleeve of the cable.

Looking at a cable plug for Cat5e or better you should see eight wires.

Previously cables provided with older Hub models were Cat5 (four wires). Hub Two supplied cables should already be Cat5e.

I think it was in the OpenReach information where they said I needed a new router. I'll check that again though

Not all routers are compatible, the Plusnet Hub 2 was designed to cater for both technologies.

Converting them is simply a case os removing the DSL cable and inserting an Ethernet cable in the socket labelled WAN. No router settings need to be changed.

When you do this don't you loose a LAN cable connection (i.e. LAN ethernet cable connections go down from 4 to 3, as one of the connectors is now used for WAN (internet) connection.) ?? Don't know if that's important in this case or not.

If the number of ethernet LAN connections is a problem it's easily remedied by a simple/cheap ethernet like this

On a Hub 2, the WAN port is not usable as a LAN port even when in a DSL configuration
