I moved into a flat that has network cabling to every room, with outlets in every room. The cable is what looks like CAT7 cable (orange, thick and a lot of silver strands and what looks like foil shielding it).

When I connect my laptop directly to my router, I get 250Mbps download, and 25Mbps upload, which is correct.

When I connect my router to the wall outlet, and then connect the matching point at the Distribution Box (for lack of a better word, to my laptop, I get 90Mbps.

Why is this? How can I test it? How do I fix it?

The cables in the house are they connected to a switch or directly to your router?

The cables from the rooms etc. could be going into a 100mb switch?

Also what router do you have?
 
Sounds like the in-wall cabling is CAT5. Limited to 100Mb.

Whats your internet speed?
Sounds like you're getting a 1Gb connection connecting your laptop directly to a RJ45 port on your router. So that's all good.

Check your network speed when connected to the wall outlet. Does it show 100Mb or 1Gb?
 
If everything is gigabit everywhere,then you have a broken pair of the 4pairs in your in-wall setup somewhere
Also sounds like shielded grounded cat5/cat6

First thing I would recommend would be to get into the roof, inspect a portion of the cable and see if it is indeed 1gbit capable.

Good luck getting into the roof... :oops: But I get what you are saying. I'll have a look.

They are going directly to the DB box, no router. It's literally a RJ45 in the wall in whichever room to the DB box. A picture of said db box:

Got some Vodafone Station router (TG3442DE), which is Gbps capable.

Internet speed is 250mbps down and 25 up.
 
Have you tested one of the other outlets to see if it is all of them or just the one outlet.

Also, check the back of that panel, one of the wires on that connection may not be seated/connected properly...

You could also invest in a simple cable tester

The simplest test. Seems like that point is an issue. Another point works at 1gbps.

See
If everything is gigabit everywhere,then you have a broken pair of the 4pairs in your in-wall setup somewhere
Of the 4 pairs only 2 are needed for up to 100mbps,i've seen it happen where just the gigabit pair(s) are damaged
 
AFAIK CAT7 is not standadised, so you could have Cat5 (100Mbps limit) with some additional isolation. You want Cat5e for 1000Mbps , or CAT6.
 
Use one of these, check all cables are working as expected :


If it's cat5, you've got a problem, Cat5E will do gigabit (not exact gigabit) and Cat6 is really what you'd want.

Start with a tester I think.

(Yes I'm aware the link is for RS ZA and he's in Germany, it's the idea that counts).
 
I struggled with a similar issue, ended up being Cat5 cables. Switched to 5e and all sorted.
