Out of nowhere i noticed my internet was a bit slow so i checked the speed and it was slow so i called the isp n they said the speed was fine so i checked the speed using wifi and it was fine too but when i check it the speed on my pc using ethernet its stuck at like 9/10 mgbs i changed cable, reseted router, diasabled wifi, disabled wake up on lan nothing worked. I had the same issue with my other laptop but when i unplug and plug the cable the speed goes from 9 to 90mbs i tried unplugging and plugging on this pc but didnt work.

Try resetting all network connections on your PC.
Open Windows Settings (Windows key + I key), click 'Network & Internet'.
Select 'Status' on the left pane and on the right click the 'Network reset' link.
That will reset all network settings to default.

I tried it now and i restarted the pc at first the ethernet was going identfying then disappear so i went to control settings i disabled it and i enabled it again now it is connected but the speed is still stuck at 9mbs
 
Set network speed manually.
Open Windows Settings (Windows key + I key), click 'Network & Internet'.
Click on 'Change adapter options'
Right click you Ethernet connection
Select 'Properties'
Select 'Configure' button
Select 'Advanced' tab
Find 'Speed & Duplex', and if it's on 'Auto Negotiation', change it to match the speed of your PC network and your router port.
Press 'OK'

If your PC has a Gigabit network and your router has Gigabit ports then select '1 Gbps Full Duplex'
If your PC has a Megabit network and your router has Megabit ports then select '100 Mbps Full Duplex'
If your PC has a Megabit network and your router has Gigabit ports then select '100 Mbps Full Duplex' and viceversa.

I tried it and i sat it at 1gbps full duplex and when i tested the speed was 1mbs so it decreased so i just returned it to the normal auto negation

Download a diferente driver version for your Ethernet controller.
Uninstall the Ethernet network controller from Device Manager and delete the drivers.
Install the downloaded drivers.
Oke i tried diffrent verisions of drivers still the same
btw in the status in adapter settings it says 10mbs so maybe thats capping it but i checked the speed and duplex its auto negoation and i tried 1gbs full and it became slower

Okay when i restarted my pc the internet was back at 10mbs i kept pluging n unpluging the adapter several times until it gave me the right speed so what could be causing this and how to fix it
 
If your laptop is hitting 100Mbs and the USB to Ethernet adapter gets 100Mbs then the issue is with your PC Ethernet port, chip or settings.
Visually look at the Ethernet port in case it is damaged.

I was looking at your IP Config results and there are 7 network adapters listed.
Delete them all, reboot, and let Windows configure it

On your DNS entry it shows.
DNS Servers . . . . . . . . . . . : fe80::1%21
192.168.1.1
fe80::1%21

It should be DNS Servers . . . . . . . . . . . :192.168.1.1
If you have not manually change it the the TCP/IP Stack could be corrupted.

To fully reset TCP/IP Stack
Open Command Prompt as Admin

Type each command below, hitting the Enter key after each one. After each one resets you will see 'Restart the computer to complete this action.' Move onto the next command and after you have completed all the reboot

netsh winsock reset
netsh int ip reset
netsh interface ipv4 reset
netsh interface ipv6 reset
netsh interface tcp reset
netsh int reset all
ipconfig /flushdns
nbtstat -R
nbtstat -RR
netsh interface tcp set global autotuninglevel=disabled
netsh advfirewall reset

Oke ill do it asap
No also the usb to ethernet is stuck at 10mbs but when i keep plugging and unplugging it then it works fine which happens both on the pc and laptop so maybe its it's something with the router
