The problem is that my onboard networkcard is capping my internet speed in some applications. But it isn't capped at one speed. For example Firefox gets 130Mbit, Bethesda launcher 170Mbit and steam for some reason all 225Mbit download. My laptop is capable to get in every application full speed though.
the networkspeed is 225Mbit down and 20Mbit up. However the cable does provide the full speed with no issues on my laptop.
I'm using two cables with a coupler in between. The cable from the router to the coupler is a CAT5e and the second one is a CAT6. The coupler is capable of delivering the full speed.
The cablelength is 35 meters.
everything seems fine without the coupler. I tried diffrent ones but nothing solved the issue.
trying to force the card accepting gigabit didn't work either.
At this point i don't know what should i do next. Perhaps somebody can help me.
