Z510 Dropping ethernet Connection


I have a Z510 and since the beginning I have always had issues with the wifi and the ethernet speeds, but having upgraded to Windows 10 i have been having continuously dropped connections that does with the speeds not matchcing what I was getting on other systems. The big issue I had is that being connected to through ethernet directly to the modem/router I would get random drops in connection where the status would say that I am disconnected when obviously am not. 

The relevent drivers that I have installed are as followed:

For the WLAN driver - Broadcom 802.11n Network Adapter -

For the LAN Drivers - Realtek PCIe FE Family Controller - 10.23.1003.2017


I have tried numerous different drivers versions and the drivers taken directly from the link below.

The issue has not been resolved through every possible troubleshooting steps that I found on the internet.

Re: Z510 Dropping ethernet Connection

I would try executing the following commands one at a time from an elevated Command Prompt (Admin) if you have not tried them already.   


Note:  It is probably a good idea to create a System Restore Point before before proceeding. 


  • ipconfig/release 
  • ipconfig/renew 
  • ipconfig /flushdns 
  • netsh int ip reset c:\tcp.txt 
  • netsh winsock reset
  • Reboot system and test

Also I would reset the router, which I presume is the address you are pinging.


As a more drastic step, you can also reset all of the network components Windows 10

  • Right-click on Start and select  Settings
  • Select  Network & Internet
  • Select  Status  in left pane
  • Select  Network Reset in right pane


Best of luck,

Re: Z510 Dropping ethernet Connection

Okay so I followed your first set of steps to the key and and immediately came up with the same problem of the ethernet disconnecting. I have task manager open and you can see the ethernet come up as disconnected for approximately 3-5 seconds and restart.

Re: Z510 Dropping ethernet Connection

Hi 5pida


I have exactly the same issue as yours. 


My ethernet keeps dropping and switch between ethernet and wifi, and I am driven to crazy some time when I would like to download something.


By the way, I noticed that when I directly plug the ethernet to the router, it can be better than when I connect the cable to switch.


do you find any solutions?
