Router or pc problem?

Hi all,

Not sure where to post this but..
I have recently bought a 15m ethernet wire cat7 (yes I know it's not entirely necessary for home use but for price and such is fine). I bought it to get the full speed to my pc straight from the router, as my current set up is using power lines and giving my pc around 120mbs as well as my Xbox about the same.

When I have tested the wire I tried it with nothing else plugged into my router and straight into my pc, but the output light on the ethernet port is orange and only outputting 100mbs.

So I used the 15m wire from my fibre port into my router and it was giving my router the full speed and a green light.

Any suggestions on what might be making it only 100mb output where everything else is ok?

I have sky internet of 900mb and get around 690 of that.
On WiFi from the router I get around 590 on test.

CAT 7 is a datacenter standard, some people do use them without really understanding why it's rather pointless for their environments.

There are 6 different CAT 7 cable types, only one of which can be used in home environments. And that one has specific setup requirements like bend radius that need to be met.

I take it you tried it in other ports as often routers (especially ISP supplied ones) will have a mix of 1Gb ports and 100Mb ports.

Do you have a link to the listing you bought from?

Can you also post your full specs from the order page?

Yes I have tried all of the ports each go to orange, the current wires and set up I have get to over the 100mbs so doesn't seem to be an ethernet port issue on my pc or router. I know car 7 isn't fully needed but I don't understand how it manages full speed capability from my fibre box to my router but not from my router to my pc.

Thanks for confirming.

So both the switch port and the PC port work over 100mb with another cable.

If it were reaching say 81mb or 365mb or something random, I would say it’s just a faulty cable.

There are only 2 possibilities:

1. somehow the network adapter has changed to 100mb max, it’s easy to check.

Ethernet Adapter > Properties > Configure > Advanced > Speed & Duplex

Reboot if you’ve changed it

If it’s not and it’s still at 1gbps then it would be worth testing again with another cable. If that offers proper speeds then you know..

2. It’s a fake cable, it’s an old CAT5 cable redressed, or it’s not designed to CAT standards

Judging by some of the reviews I suspect it’s a fake.

The cat7 cable is ok at delivering the speeds to the router and gives the same speed as the cat 6 cable currently in use, so that seems fine and the cable can manage up to 1gb through that.

My current set up is cat 6 cables but thought power lines and offers just over the 100mbs to my pc and console.

I have just checked the setting you mentioned and it was set to auto negotiation. I have changed it to 1gb but hasn't made any difference.

So I am at a bit of a loss as to what's different when the cat 7 cable is used from the router to the pc.

I have also logged into my router and the output setting are set to gigabit ethernet

It’s a fake cable, or it’s one of the types not suitable for home use.

TLDR, don’t buy CAT 7 unless you’re buying from official outlets, don’t buy network cables from Amazon, there are so many fakes out there especially with CAT 7. CAT 7 has never been developed for home use to this day and it has to be laid professionally anyway with strict guidelines on bend radius, it’s designed to directly power ports and in harsh environments.
