Ethernet doesn't have have a valid IP configuration
Yesterday I turned on my laptop and I got a message saying I had limited network access.
Its conected via a ethernet.
Running the network diagonstic I got the erro message in the title.
The laptop had a dynamic IP and DNS.
I tried pluging in my 5GHz and got the same result.
I'm at a loss, the only thing I can think is that I tried a tool from the web that would find the best DNS for you.
I cannot access my router via the laptop, but can access MS Onedrive though.
I plugged my netbook into the same ethernet cable and can connect without issue, (Using this to tyoe this)
I googled and tried the options without luck.
Help.

Re: Ethernet doesn't have have a valid IP configuration
Have u tried rolling windows back to an earlier date? I know its risky but maybe in this case its worth it.

Re: Ethernet doesn't have have a valid IP configuration
Believe it or not I'm doing just that as I type.
Failing that ask the IT guy at work when I go back to work on Monday.

Thank god for that.
A system restore point fixed it.
I still would like to know what went wrong.

I went through a stage where a windows update would always kill my network on a pc - for some reason the combination of the driver and the update would just stop networking from working, so I always had to roll it back

Re: Ethernet doesn't have have a valid IP configuration
Done all that.
I even gave the laptop a static IP.
I think it's a windows update that's buggered

Re: Ethernet doesn't have have a valid IP configuration
open command prompt as admin
type; netsh winsock reset
reboot machine
test network again
if this fails, open command prompt as admin again and type: ipconfig /all
what IP details is it showing for your network interface you are trying to use?..
- IPv4 address
- Subnet mask
- Default gateway
- DHCP server
- DNS server

Re: Ethernet doesn't have have a valid IP configuration
I have a similar problem with my desktop since the recent creators update.
Although I don't have fix I do have a workaround which works for me.
4 out of 5 time I switch my pc on to find no Ethernet adaptor installed.
I check my device manager and the main network adaptor has a yellow warning triangle.
Right click and scan for hardware changes fixed the problem until the next power on.
This may help for you?

If that works for you then fair enough, I wouldn't put up with it and I suspect many others wouldn't either.

Re: Ethernet doesn't have have a valid IP configuration
I do agree its not the best, but rolling back may be more hassle.
I live in hope that a patch may fix it. To be honest I think its the Ethernet Lan driver is not 100% compatible with Win10.

Re: Ethernet doesn't have have a valid IP configuration
Rolling back is not a satisfactory option either.
Always check drivers with the manufacturers site rather than rely on microsoft update.
It may just be a case of microsoft not testing it and allowing it to be "digitally signed".

Re: Ethernet doesn't have have a valid IP configuration
I have partley solved it.
I remember the IT guy telling me to uninstall Avast AV (via removal tool).
I did and I'm up and running.
Now what do I do with regards to AV, try and reinstalling Avast or use another, I'm running 8.1

I would try Avast again and get rid of 8.1 and move to 10 it is far better.
