Ethernet Connection

[#1]

I've bought a new Cat 8 ethernet cable to connect my PC directly to the router but for some reason it doesn't work. The PC shows up in the hub manager / my network but says not connected. Also says under IPv6 addressing: This device either does not support or is not configured for IPv6 addressing.

I've tested the cable elsewhere and tested the router with another cable so cant understand what the issue could be. Any ideas?

@jimbob99 welcome to the forum

This device either does not support or is not configured for IPv6 addressing.

You will see this message if the connected device is not setup to use IPv6 or it is not connected. Plus net do not use IPv6 so you can ignore the message.

Assuming the Hub Two only has three LAN ports, have you in error used the WAN port?

This Hub remembers a device that has previously been connected.

When you view the attached devices is the PC name a Red or White background

Connection status:

Red = connected

White = not connected

Thanks for the reply. I tried all the lan ports and background is red. It recognises the pc is there but won’t connect. Could it be because it’s a cat 8 cable, I read elsewhere it might cause an issue.

It could be one of the eight pins in the plug not contacting to the ones in the socket.

Cat 8 is a bit overkill, cat5e or 6 would be good enough.

Depending on the internet speed if you are sub 100mbps (not full fibre) for the short term you could use a cat 5 cable.

@jimbob99 

Just in case it is one of the pins not making contact properly, (as suggested by @Dan_the_Van ), have you tried using the ethernet cable the other way around?

@Mr_Paul - Without causing upset, Cat 8 have no purpose because nothing but specialist tech supports 40Gbps and people setting up a 40GBps backhall aren't using cables from ebay and Amazon and the likes. I digress a bit, the point I'm making is that I would be very dubious that the cable is capable of the suggested speed and are 100% crimped properly and isn't dropping packets. I would try another ethernet cable that's cat5e or 6 of solid copper and stay away from cat7 and 8 and copper clad aluminium (CCA) cables.

I’ve sent back the cable and bought a cat 6, fingers crossed! Thanks for all the replies.

@jimbob99 - Good look.

@jimbob99 Even Cat6 is overkill, people rarely check what cable is ACTUALLY required. Cat5e is perfectly good for Gigabit speeds.

To run at up to 100mbps Ethernet cable only actually uses four cores, in fact if you look at a lot of older cables supplied with routers you will see they do indeed only have four cores.

I've got network wiring in my house run (long ago) using 4-core telephone cable and it works fine at 100mbps which is all I need, even now that my broadband has been upgraded to "fibre" at just over 60mbps. The advantage of phone cable, and yes it is twisted pairs, is that it's thin, flexible and unobtrusive. Especially compared to Cat 6!

Given the developments in Wi-Fi I've never seen a need to replace this.
