1.0 gbps adapter only 100 mbps internet

parquelis · Mar 12, 2018

Hello everyone.

This is my first post, so my apologies if i created this thread in the wrong section. Heres my ordeal:

I bought a house, signed a contract with the ISP for 400 / 40. I had a cable from downstairs to the attic wich i replaced due to slow speeds ( only 80 mbps ). Now i have a new cable wich works fine. I plugged that cable into the switch in the attic, wich on its turn gives internet to another cable to my "gaming room". Now this is a cat5e cable, so this should give normal speeds.

But as soon as i plug the cable in the computer / laptop it only gives 80 mbps and the adaptar shows as 100 mbps.

Heres the weird part:

As soon as i put a cable (allready fabricated with the plugs on both ends) in the switch in the attic, it gives me full speed on the laptop of testing.

My question is as follows:

- Is it possible that i used the wrong plugs?
- Does cat5e only support 100mbps?
- Is it possible that my adapter of my computer is dying, and therefore giving only 100mbps?

Again, this is my first time posting here. Anything is helpful, thanks in advanced.

PS: Things i've tried

- New cables
- Different computers / laptops
- Updating drivers
- Screaming real loud at the computer
- I've turned it on and off

ISP told me its a faulty cable.. Changed that, it's not that.

I attached the plugs in the following color order, with the clip down:

Orange/white-Orange-Green/white-Blue-Blue/white-Green-Brown/white-Brown.

Regards,

Vincent.

I am confused as to which cable is which but a cable can still be defective and work on some devices at 1gbit and others at 100m. Some devices just tolerate cables that are slightly out of spec more than others.

In general the cable will drop to 100m if it can not get signals on the blue/bluewhite and brown/browwhite pairs.

For a home users there is little you can do. They make cable certification/testing devices but they are extremely expensive and the cheap testing units just test to be sure the wires are in the correct order not that they can actually pass data.

All you can do is cut off and reterminate the cables until they work,all it takes is 1 pin to not fully cut into the insulation and it will not work.

Be sure you are using pure copper cable. The CCA crap you see being sold is not certified and has all kinds of issues related to the aluminum. You also do not want to use flat cable or that thin cable. Both contain wires that are too small to be certified cable and they have issues going distance.

Any pure copper cat5e cable with wire size between 22-24 should work fine.

If it is in wall cabling you may want to consider using keystone jacks rather than crimp on rj45 plugs. Those are much easier to get right because you an do 1 wire at time. You would need to buy some short commercial patch cables to connect from the equipment to the jacks.

Hey Billy, thanks so much for responding.

I found the issue. After your reply i checked both cables and the one going from the switch to my PC was faulty. Swapped this one out and instantly got 1gbps.

Thanks so much!
