CAT 7 cable?????

[Lord Farquart]

Since I had fibre installed at home, I have noticed that the nic on the wife's desktop shows 10mbps, but all equipment on the network is 100mbps. The nic itself shows up as a gigabit card. Was gonna replace it, but decided tonight to try another cable. Voila, 100mbps and I can now actually do speedways on it, as it is the PC I manage the routers with.

Questions, these are pretty decent imported pre-made-up cables from Germany. As per the attached photo, it is also CAT7. Does CAT7 need different picture or something to run at more than 10mbps? Why would this cable limit the speed?

I have had a lot of issues like that at work. Where the Pc says 10mb but should be 100mb.

The cabling people just tell me its bad connections in the RJ45 plugs.....

Try the below: Windows 7/8/8.1 and 10

Click "Start > Settings > Control Panel".
Select "Network and Sharing Center".
On the left panel select "Change Adapter settings"
Right click on the "Local area Connection" and select "Properties".
In the "Local Area Connection Properties" window select the "Configure" button.
Select the "Advanced" tab.
In the scroll list of options find "Speed & Duplex" or "Link Speed & Duplex" and select it.
The NIC speed will be displayed in the "Value" drop down menu.

For the most part, odds are the RJ45's is the issue.

How?

As in 2 points wired differently or are you saying the physical copper plates are broken?

Can easily be a cable that pulled out of the crimp. Seen that many times. All it takes is one small wire.

There is also a possibility that the issue is the physical cable being broken on the inside somewhere.

Ahh okey, I understand now.

Believe it or not as much as RJ45 is a universal standard there are minor deviations between the ports and cables.

Especially manufactured ones tend to be more full of **** and you’ll often see it on a given brand of hardware.

A particular cable won’t work on a bunch of Apples, but will work on a Dell for instance.

It’s not the cable itself (as in CAT5,6,7) but the combination of port and connector.

Simple solution. Use another brand of cable or one you crimped yourself.

As illustrated above in many cases the cable is known to be working perfectly and on other hardware.

But you are right it is ultimately the RJ45 that is the problem.

Whether the male or female end. Maybe they are bisexual or trash or something.

Tried that with no result. That is why I was going to change the NIC. Just by changing the cable, and leaving all other settings the same, it went from 10 to 100.

As for wiring/pinouts, Ive had issues with 568A/568B etc. I know to not mix them up. This is 568A wiring with CAT7 cable. I will go try this cable out in some other setups. Currently it is lying in my son's LAN box.

What will cause that behavior, surely if both ends are wired correctly then it will work everywhere unless the apple devices requires straight through and dell required crossed.

No nothing like straight or cross over.

Simple manufacture tolerance or deviation off spec.

I’ve even measured them before and you’ll see a minor difference in size on the connector.

So basically it’s just a case of not making contact. But the cable itself works and you can use it elsewhere no problem but it won’t work on a specific series of machines etc.

Only ever experienced it with manufactured cables. So could very well be a fault in a batch or something or something damaging the connector ever so slightly in the process.

If you think about it the gap between those pin outs is very very small.

Ahh okey I understand, but then yes it will simply be a bad batch. Or one of the devices are not adhering to the standard and have a Slightly bigger RJ45 socket.

Just trying to get all info as to what issues can arise.

Coolest thing I love about ethernet is the pin order doesn't matter as long as it's the same on both ends. I've made a lot of combos with the colors that feels better for me.

Yeah like I say it’s usually more the female socket that won’t comply for a given set of hardware.

As for pin outs that really applies to any electrical or other contact connection. Colours are just there as a standard for the next guy who comes along.

Ultimately the only reason standards exist is for the next person who works on something.

So your suggestion for him to get 100mbps when it's clearly a cable fault, is to fiddle with software?

In some cases if you force your NIC to a specific speed it makes a difference. With some unmanaged desktop switches that have power saving the NIC will connect at 10Mbps/100Mbps/1000Mbps (different every time you connect), but if you set your NIC to a specific speed then the switch will match that speed on the port linked to your NIC. Replacing the cable doesn't always make a difference in this sense.

If replacing the cable made a difference in this case then its fine.

Unless you have to do support on a building where the idiot tech/it did not stick to a standard. Short flyleads/patch cables is ok but when both ends are not in the same room it becomes a nightmare.

Also found signal to noise can affect network speed esp if the moron ran the network cable next to power lines for 20+ meters and such.

I agree, it is the most important. Additional contact resitance introduce a noise. I also saw incorrect type of plugs used: two-prong forked type designed for solid cable was applied to the factory made patch cable. Solid and patch cables require different plugs, not many people know it.
