Hub 5 Ethernet Issues

Joining in

Morning all,

Have a bizarre issue with the Ethernet on my hub 5. I’m using all the ports on the back, one goes to my tv, one to a Philips hue and then 2 go off to different rooms in my house for hardwire connections.

One of the connections that goes off has always been problematic. It just randomly drops to 10 or 100mbit and sometimes disconnects completely. The wiring is fine though. Have tried different cables, different ports on the back of the router, restarted the router etc….

It’s really getting quite annoying as 90% of the time it’s fine but then it’s suddenly not. It must be the hub 5? But I don’t get why, like I said I’ve tried different ports on the back. All the other connections are fine and run at full speed. 

Thinking of buying a switch and just plugging one cable into the back of the hub… 


Fibre optic

Obvious start points.

Min 5e cable anything more is expensive overkill unless you are runing 10Gb or greater on your LAN.

What is plugged into the remote end. Switch  access point etc? Or a PC. Are you able to set speeds on that device or is it auto negotiated.

All cables are cat6 and I’ve tried a number of different ones. I’ve used a network test kit on the connection that’s dodgy and it’s reporting back no issues. 

The 2 connections that go to other rooms, one goes to a switch which then feeds into an access point, games console and tv. This is the connection that’s always been fine. 

The other feeds my work pc directly and this is the one that’s been problematic. 

Thanks for your post on our Community Forums @Lostsheep555, and a very warm welcome to you!

Sorry to hear of the issues with the connection to the PC, have you possibly swapped the ports on the hub for the ethernet that runs to the PC?

I'd be interested to see if the fault falls in line with the port on the router, or with the device connected.

Kindest regards,


Hi David,

The fault appears to be with neither. I have swapped the ports on the back of the router and I’ve tested it with other equipment at the other end and still the same issue. Fine sometimes then suddenly disconnects for several hours then back up again. Or drops from 1000/1000 to 10/10 or 100/100  

I’m starting to wonder if it’s my wiring because like I said everything else has been perfect aside from this one run through my house. Even though my network tester says it’s fine I can’t see how it can be anything else. 

Going to replace the faceplates over the Christmas break and re-do the punch downs to see if that fixes it. 

Hi Lostsheep555, thanks for the message and sorry to hear that you are having Ethernet issues. 

Would you be able to set up a BQM here

Please let us know how it goes?

Kind regards, Chris.

Guessing its the cable length a better cable CAT6 with shielding might help or get a 5port switch next to the hub with a short cable then long cable to switch should work.
