Slow network speeds out to garden studio

[GodAtum]

I have about a 30-40m CAT5e run. In iperf I get about 100 mbps. In my home, I get 800 mbps.

Would this be due to cabling? Very annoyed if it is, cause it was very expensive to lay down.

Broken wire or bad termination.

100Mbps only requires two of the pairs to be connected, Gigabit needs all four.

How long ago was it laid?
Has it ever gone faster?
Was whoever laid it qualified
In networking?
Ie able to test the speed
Once they finished laying it
Not just a builder or landscaper etc

It's probably a bodge job but you might as well make sure that the computer in the studio isn't at fault (take it into the house and test it so the buried cable isn't in loop).

If the cable has to be replaced, you might want to consider pulling fibre through instead. A lot of professionals frown on running a length of copper between two buildings.

I'd start by checking that if is correctly terminated.

Have you got a tester? Or a punch down tool?

Test, or re-punch the sockets/patch panel or whatever at each end.

If you paid someone money to lay a cable, and its not meeting the agreed standard, then get them back to re-terminate it or re-pull it.

Show photos of the connections (if they are modules, show photos of the back of them).

If you like, I can post you a set of tools and modules to fix the issue, along with a tester to test the cable.

As long as you send them back after!

Just see if it's connected at 100m or 1000m first.

Thanks for all the advice .. looks like it was my network card. Swapped ports and it's now around 800 mbps.

Should get 950mbps on gigabit file transfers
