Intel I219-V refuses to establish a connection! always disconnected !

[mhamdy]

My problem is quite simple, yet I can not find a solution for!
When I plug my cable into the Ethernet port in my new PC, I can not get a connection established to the router! That's it.
.
Please note the following:
1. I219-V driver version 12 (latest, I also tried the one with my MoBo, no luck)

2. Intel PROset version 22.6 (latest)

3. My computer successfully recognizes and installs the Ethernet driver (the card is not dead )

4. The network cable is working perfectly ( I havel also used different cables)

5. Using the diagnostics in Intel PROSet, the on-board card actually responds when I start the "Led Blinking" (it is not dead)

6.Using the diagnostics in Intel PROSet, it fail when I test a connection

7. The router (linksys 1900 ACS) is working perfectly (WAN and all LAN ports) - DHCP is enabled and working perfectly.

8. It only works rarely when I set the negotiation mode to 10 Mbps full duplex

9. When I set it to "Auto" or "1 Gbps full duplex" I still get disconnected.

So, in short, I am sure everything in the system working properly ( as I used different routers. cables, laptops, etc) except for this cursed network adapter, so any ideas ??

Problem solved.


I tried to restore the firmware to defaults using "EEPROM using Intel® Ethernet Connections Boot Utility, Preboot Images, and EFI Drivers" using the following command:

BOOTUTILW64E.exe -NIC=1 -DEFAULTCONFIG

Now I got the 1 Gbps STABLE connection.

Hi,
I have the same problem. Did you have any problem with this adapter after this solution.
Can you let me know?

Hello all,

I have Asus Strix z270H with the intel networking card in Windows 10 Pro.

Seems like the Open WRT router I have in my system does not know how to give IP6 address to the PC and the driver for the NIC refuses to connect most of the time.

My solution was to disable the Internet Protocol Version 6 (TCP/IPv6) in the Ethernet Connection's properties.

Since disabling the IPv6 the connection has established immediately after wake up from sleep or from boot up.

Hope this helps some of you.
