Aurora R11, Ethernet port not identifying network
For the past week I can only connect to the internet via WiFi. The Killer E3000 Ethernet port connection repeatedly shows unidentified network. Computer Ethernet port has solid orange light with flashing yellow.
Here is what I have tried:
updated BIOS and network card drivers. No change.
deleted/reinstalled network card, no change.
plugged same cable from router into a different computer. That computer connected no problem.
tried command prompt ipconfig release/renew. System released and renewed IP, but still not identifying network.
I tried setting a static ip/gateway for the system. Still same result.
tried Ethernet connection from modem instead of router, still no luck(connection from modem works on different systems).
called dell customer service, they ran through multiple troubleshooting methods via remote access, including everything I tried, and even attempted a system repair. No change to connection status. Rep said it is a configuration issue with the router and not covered by warranty (if that were the case I would have trouble in other system, or one of the above troubleshooting techniques would have worked I think).
I think the Ethernet port went out, but can’t seem to convince customer service that’s the case. What else can I do to fix this. I’m willing to try anything at this point.

This did it! If forced the 2.5gigabit card to connect at 1GBPS and it connected immediately. Thank you very much!

Excellent. Good work.
So I guess we need to get used to trying this (old/rarely needed) work-around again.
Interesting that the "link light leds" light ... even when it's broken.
I wonder which machine is failing the auto-negotiation ? (the NIC-card or the router/switch).
Seems like there should be a setting to just exclude 2.5gigabit (but still autos between 10-100-1000 or at least 100-1000).

@JasonSchock
Something like a setting described as Duplex Speed with a vaule like Auto negotiate.
Look for something like "1Gbit/s duplex" in the values

@jtylersimmons84 @Vanadiel I am having this exact issue. New Aurora Feb 2021 and suddenly the NIC stopped working and telling me "Unidentified network". It's directly wired to a Netgear Orbi.
A USB ethernet adapter works fine with a new CAT6 cable, so the problem is isolated to the machine.
How exactly do you force it to 1Gb?

As per picture below. You can force it to only connect at a certain speed by making the appropriate selection from the Value drop down menu.
I would also disable the following items. You might have some of these, or all of these, or none of these:
- Power Saving Mode
- Green Ethernet
- Gigabit Lite
- Energy Efficient Ethernet
- Advanced EEE
- Auto Disable Gigabit

Try opening powershell and type in the following command: get-wmiobject win32_networkadapter -filter "netconnectionstatus = 2" | select netconnectionid, name, InterfaceIndex, netconnectionstatus
Meaning of the networkconnectionstatus value:
0 Disconnected
1 Connecting
2 Connected
3 Disconnecting
4 Hardware not present
5 Hardware disabled
6 Hardware malfunction
7 Media disconnected
8 Authenticating
9 Authentication succeeded 1
0 Authentication failed
11 Invalid address
12 Credentials required

@Vanadiel @markburv Thanks for the help, no luck. I'm not sure what could be going on. It just refuses to get an IP address from the router.

From the advanced tab scroll to “speed and duplex.”
on the right side it will have a drop down box under “value.” this is most likely set to auto negotiation. Change that to 1gb/s and you should be good to go.

I have this same issue where everything was working fine, then it stopped. Dell said it was the NIC card and I needed to ship my system off to them. What were all the steps you tried?

The answer for me was that my Card had auto selected the connection speed at 1git, I reset the speed down to 100 MB and it worked like a charm. Seems that while the network card accepted faster speeds, my modem/router would not. I know someone posted on this forum how to do it, but I can’t seem to find it right now. If you google how to change the speed duplex you should be able to figure it out.
