any way to repair it without starting all over?

i hope they can help...

i'm desperate...

done. topped at 99MB/s

you mean connecting the pc and the laptop with a cable? idk how to do local transfers.. never done it

of course. it says 1gb on both the mb lan port and the usb adapter, i said that on the post...

yes, on the pc a google drive file was going 2mbs and inside the vm is going at 50mbs... 60mbs on the laptop

sorry for the bad english. i have a gigabit connection (940mb day1 700mb tested with my laptop port today) my motherboard is msi z170 gaming m5, the lan port is e2400 atheros killer, the cable is cat6, the swicth is gigabit and it always worked. since a bit i found the connection not fast as always. i found my speedtest at 140mb, i tried updating drivers, cleaning the drivers and istalling it from scratch, no luck. then i thought the lan port was broken or something because i tested the same setup with the same cable etc with my laptop and the speedtest was 700mbs , so i ordered a usb 3.0 to gigabit from amazon basics. and the results where the same.... then i tought to test the new sandbox virtual machine with windows 10 1903. and... the results were 400+ mbs.. with the hyper-v virtual ethernet adapter inside the sandbox. both the e2400 and the usb adapter are listed as 1gb links. the duplex is in autonegotiation by default in both. ipv6 is not the problem. i havent found any program that could limit the bandwith like that.. the only one was killer device center but i unistalled it. i need help. its a crazy situation. i really do not want to fresh start windows 10... to recap the cable is good beacause i can get 700+ on my other laptop i tryed resetting netsh etc with no luck the speed inside vm is 450+ and outside is 145 i tried in safe mode, still 145. qos limiter is not the cause, disabling it i only gained -1 or -2 ms of ping with the same speed. i really don't want to nuke the os.
