Ethernet Speed diffrent on every pc

[Marc030]

Hello guys,

 

A weird issue has come to my attention about our network.

 

We have 2 pc's connected with cat5e cables and a laptop all of them have intergrated gigabit network ports.

We have 120mbits down and 10up but on both pc's only get a shaky 80-70 down and 10 up. Using the same cable that the pc's use and sticking it into the laptop i am able to get 120 down and 10 up. so i cant figure out why its diffrent on the pc's and laptop. all the network drivers have been updated.

 

Anybody have some insight in this?

 

Greatly appreciated!

Sure your pcs have gigabit ethernet?

[Marc030]

yes, both have gigabit this is a picture of my main pc:

and there is no switch/router in between that may be 100mbit rated?

Modem --> Router ---> PC

 

Using the same cable: 80mbit in pc and 120mbit on laptop

Overhead, HDD write limit, different interfaces. If it was on 3 identical pc's then i would see a problem.

What is the way you are testing your connection? Also it matters what programs you are running in the background because these programs may fetch information from the internet. Connection speeds are always going to very.

I would have to agree ^^

I test it using the speed test site my ISP has set up.

 

About the setup, they are all three quite good, all have SSD's as main boot partition and i shut off all the background stuff  just now and still got the same result.

 

i will try to find another pc and test it again.

 

Thanks for all the help so far :)
