Issues with my new Ethernet cables

Good evening,

I have some problems at home with my internet. Last week I installed an ethernet-cable to my room upstairs, mainly because our wifi is not that great for gaming, but after installing everything my ethernet cable does not work on my computer, neither on my brother's. I thought it was because something was wrong with my computer, but when I used the cable downstairs, which is connected to the router, my ethernet port works fine. My download downstairs is 188 Mbps, and upload 25 Mbps. But there is something very strange. When I use the laptop of my mother, the cable in my room( that doesn't work on my pc) works. It does not work perfectly, because my download upstairs is only 95 Mbps. My questions are two things. My first one is, why does the cable in my room work on the laptop but not on the desktop? And second, why is there a difference of 90 Mbps download between upstairs and downstairs?

Thank you in advance!
(sorry about the mistakes in language)

OK, that is one part. You need a simple tester to verify everything, IMO. Something like this -- https://www.amazon.com/gp/product/B004CI9NRM/
The most likely problem is you don't have all 8 wires connected somewhere. The 95Mbit speed is indicative of a 100Mbit connection rather than a gigabit connection.

It takes lots of practice to make cables and even then professionals get bad ones now and then. It can be as simple as one of the pins did not cut though the insulation correctly. They look perfectly fine but don't function correctly. There is no way to fix them other than to cut the ends off and try again. It is pretty much a guess which end is bad even with a tester.

You might be better off use keystones to terminate the wire and then short commercial patch cables to connect to your equipment. The keystones tend to be easier to get right because you can do 1 wire at a time and pull it out re punch it down if it seems bad.
