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.

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.

Re: Ethernet doesn't have have a valid IP configuration
 

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
 

Well it just did it again.

My laptop cannot find a network.

Re: Ethernet doesn't have have a valid IP configuration
 

Reboot modem and router and laptop, see what happens.

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

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?

Re: Ethernet doesn't have have a valid IP configuration
 

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".

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

Re: Ethernet doesn't have have a valid IP configuration
 

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

Can I get it for free?
