Ethernet doesn't have valid IP configuration

[emperorschosen]

Recently I invested in an ethernet cord/ethernet adapters that I can plug into different rooms so that I don't have to run a wire across the house. However I discovered that, while connected and apparently functioning (according to the adapters' LED's), the ethernet connection doesn't get internet. On my main desktop PC, it states "Unidentified Network, No internet". If I troubleshoot it, it comes up with the error stated in the title. I have also tested the connection on my laptop, which I connected directly into the router rather than via the adapters and the only difference was that on the laptop it stated "Unidentified Network, Limited".

I have already googled across the internet for solutions, here is what I have already tried and does not fix the issue:
- Plugging the cord into a different socket on the router.
- Power cycling.
- Turning WIFI off.
- Rebooting the PC/Router.
- Uninstalling/Reinstalling associated drivers.
- Disabling/Re-enabling associated drivers.
- Turning off fast startup.
- Disabling TCP/IPv6 for the adapter.
- Ensuring the adapter is set to automatically obtain IP address/DNS Server Address.
- Manually inputting the IP/DNS Server/etc. into the options.
- CMD -> netsh winsock reset/netsh int IP reset
- CMD -> ipconfig /release | ipconfig /flushdns | ipconfig /renew
- Ensuring DHCP is running and set to automatically start.
- Switching out ethernet cables and likely some more than I just can't remember off the top of my head.

The only other clue I have is that after running Belarc Advisor, I noted that it stated specifically for the Ethernet "DCHP Server: None responded".

Here are my system specifications:
Router:
- Make: ATT
- Model: 5268AC
PC:
- OS: Win 10 Pro x64
- Motherboard: MSI Z97 Gaming 5

- # of Devices: Currently 3, however as a total, there have been around 6 or 7 connected at a time I surmise.

Powerline adapters? Make and model?

What network adapter are you using: e.g., built-in motherboard, PCIe, USB adapter?

Run and post the results of "ipconfig /all" (without quotes) via the command prompt.

What is your router's IP address?

Your wireless adapter is looking for and finding 192.168.1.254

Check your Ethernet adapter's configuration.

Also ensure that you have only one network adapter (wired or wireless) enabled.

 

[emperorschosen]

That's the IP address. I've tried disabling the wireless adapter and manually setting the ethernet adapter's configuration, but it still doesn't connect. If I have windows diagnose it, it says that the default gateway is unavailable.

 

[Ralston18]

Per the router's configuration windows:

Can you check the DHCP IP range, i.e.: starting IP and ending IP?

Also look for the number of allowed devices.

 

[emperorschosen]

192.168.1.0 / 255.255.255.0 (default) is what was selected automatically.

I don't know where to find the number of allowed devices, but as I put in the opener there have been around 6 or 7 at least if everyone is home and the ethernet doesn't function even if I'm the only one in the house using a device.

 

[Ralston18]

Use 192.168.1.254 via your browser to access the router's configuration windows.

Does the following link present the User Guide for your router?

Page 20, Item 5. discusses the DHCP IP address range settings.

Do you have admin rights to the router?

 

[emperorschosen]

It looks like it is, and I do have admin rights to the router, I just don't know what to change or how to find the information for it.

 

[Ralston18]

According to your "ipconfig /all" posting that was run via the wireless adapter.

Disable the wireless adapter and enable the onboard Killer EB2200 adapter. Plug in the Ethernet cable and restart.

Be sure that the EB2200 is the only enabled network adapter. Only one adapter should be enabled be it wired or wireless.

If no connection is made, run the network troubleshooter. Doing so may find and fix some issue.

If, again run and post the results of "ipconfig /all".

 

[emperorschosen]

Alright, I went ahead an did that. Ran the troubleshooter, it came up with the same message of invalid IP configuration. Made sure the ethernet adapter was the only one enabled. Here's the results of ipconfig /all:

[Ralston18]

The 169.254.56.111 IP address is an IP address that Windows assigns itself when it cannot otherwise obtain an IP address.

Since the wireless configuration appears to be working (via the assigned 192.168.1.64 IP address via the router at 192.168.1.254) I believe that the problem is with the Killer wired adapter and not the router or router configuration. [Note: All subnet masks being 255.255.255.0]

If my thoughts are correct then the issue may be that the Killer E2200 is either incorrectly configured or has failed in some manner.

As you have already gone through quite a few of the reconfiguration/troubleshooting actions I am leaning towards an ethernet adapter failure. Have noted some past comments regarding Killer products and problems with them.

However, I am not fully convinced because of the powerline adapters being present.

Temporarily run an Ethernet cable "across the house" or otherwise make a direct connection between the Killer E2200 and router.

The goal is to prove or disprove that the Killer E2200 is working. If it is working then the connection problem is related to the presence/use of the powerline adapters.

 

[emperorschosen]

Thanks for the help, I'll go ahead and test that tomorrow and let you know of the results.

 

[emperorschosen]

Sorry it took so long for a reply. I didn't have a long enough ethernet cord and the room the router is in isn't exactly plausible for me to set my PC up, even temporarily. Then I got sidetracked with school. I finally tested it and connected it directly to the router and it popped up immediately. I didn't even need to disable WiFi for it to start functioning. So I'm assuming it's likely that the powerline adapters are the thing at fault?

 

[Ralston18]

Powerline adapters - perhaps.

May be some home electrical wiring issue as well: e.g., different circuit breakers.

Any power strips or UPS's when you use powerline adapters?

 

[emperorschosen]

Yes, connection to a power strip. The plugs in my room take 2 prongs and the adapter has 3, so I didn't have a choice in plugging it into the wall directly.

 

[Ralston18]

So your power strip only has two prongs?

No grounding pin?

 

[ex_bubblehead]

Yes, connection to a power strip. The plugs in my room take 2 prongs and the adapter has 3, so I didn't have a choice in plugging it into the wall directly.

The instructions for all powerline adapters very specifically state that they are to be plugged directly into the wall, NOT power strips. In addition they function best (quite often only) when on the same circuit and do not have to go through the breaker box. You also must configure the devices correctly, most often using the software that shipped with them.
