Full Fibre 145 Speed not as stated

Slunnyboy — Sun, 26 Apr 2026 18:18:03 GMT

I recently had Full Fibre 145 installed, I am only seeing speeds of around 90mbps. When I check the Hub Manager I see that the WAN Link Speed is 100mbps. I have used brand new high speed ethernet cables and expected the router to recognise this and increase the WAN Link Speed to 1000mbps.
This hasn't happened and I have tried other fixes found on the forum but all to no avail.
Any suggestions warmly received.

@Slunnyboy can you inspect the connections on the WAN port for damage ? Compare it with one of the LAN ports

From what I can see the Wan port is fine.
Until I upgraded I have never touched the Wan port since first getting the Plusnet Hub 2 several years ago.

Well it's either a cable, a wan port or an ONT fault..

Try connecting the ONT to a LAN port and check the hub 2 log to see what connection speed is reported. That should confirm if it's a wan port fault or not.

We've had a recent instance of a router with a similar fault. Does your router serial no start with an 'R' ?

Have a look at this thread https://community.plus.net/t5/Full-Fibre/Port-2-speed-limitation-need-service-moved-to-port-1-but-blocked/td-p/2043783/page/3
Ignore the bit about the port 2 of the ONT it was a red herring

20:11:44, 26 Apr.A device connected to Ethernet port 3
20:11:44, 26 Apr.Wire Lan Port 3 up, Speed 1000 Mbps

As you can see the speed was 1000Mbps when I switched ports which indicates a problem with the Hubs WAN port I presume?

Serial number of Hub doesn't start with an R

Thanks, is there another way to contact Plusnet other than by phone? The reason I'm asking isbthat I am temporarily unable to speak at the moment and it will be some time before I can.

Phone is normally the only way to contact support but I'll try tagging the help team to see if they can assist in the circumstances

@Katie_B is it possible for someone to assist here ?

I have an app Relay UK which allows me to write a text which is then read out over the phone by an operator. I should be able to manage using this. Thanks for your help and advice.
