Windows 10 Ethernet connection randomly disconnects

So i've been using the tp-link adapter for 1.5 days and it still happens. It says "Unidentified network - No internet access" in Windows and i can't access to my modem's interface etc. (Only through my computer)

After Windows restarts the ethernet adapter it gets fixed and says - Ethernet 3 doesn't have a valid ip configuration
Here is the result of ipconfig/all after getting disconnected.





The picture is taken at 14:31 so Lease Expiration can't be the issue. Thanks in advance *I Love TPU :lovetpu:

 

[FIXED]: Internet keeps disconnecting and reconnecting randomly (using ethernet)

Greetings,

I just built a new PC with Windows 11, everything is working smoothly, however, my internet connection keeps disconnecting and reconnecting randomly (every few minutes/seconds).

I am using Ethernet BTW, but my PC has Wifi as well (Which is disconnected)

I really don't know what's the issue,

Things I have tried:

- Updating drivers

- Not allowing PC to shut down the internet for power saving

- Using windows troubleshooter

can you help me, please.

Thanks in advance.

EDIT: I have fixed the issue with my new PC (ASUS Z790-F, Windows 11)

After a clean reset of my new PC, I installed the Drivers again, but the issue still occurred, however,

I did do several steps and the issue has been fixed.

1st Step: go to Device Manager > expand the Network Adapters > Right click on the (Intel Ethernet Controller I226-V) > Properties > Advanced > Energy Efficient Ethernet (Turn it Off)> then click OK

2nd Step: go to Device Manager > expand the Network Adapters > Right click on the (Intel Ethernet Controller I226-V) > Properties > Advanced > scroll down > select Speed & Duplex > set it to 1.0Gbps Full Duplex > then click OK

3rd step: > go to Device Manager > expand the Network Adapters > Right click on the (Intel Ethernet Controller I226-V) > Properties > Power Management > Un-Tick the box beside "Allow the computer to turn off this device to save power" > then click OK

Restart the PC, and the problem has gone

 

Network Disconnects in standby

NIC = Network Inteface Card, i.e. your ethernet port

if its on power saving mode, it automatically shuts the NIC down. meaning that you will be disconnected from the network.

if your on XP, go into device manager, right click the network adapter. and see if you can find a power saving mode, turn that off.

if your on vista its the same thing.
