Would suggest you disable Windows handling updating drivers. You gain back control. If you are interested.
Windows + R keys
Enter Sysdm.cpl
Click on Hardware tab
Click on Device Installation Settings
Click on No
A menu appears (first time) click Never Install driver software.
You may get a warning. Click the option that says I’ll take care of it (not exact words)
Unfortunately this is not enough. You must also block the driver update using the show/hide tool that hides unwanted updates (so they do not install with the others). This is really useful for blocking unwanted driver updates. Until there is a newer update that replaces the one hidden, you are safe.
I have the exact same issue, and it says "Network is not identified", and I have a router in between.
I already have tried reinstalling the driver, flush dns but nothing works. I have had this problem before, but it resolved itself, and now it popped up again.
All other devices, other than my PC have internet connection
Hi seba6560. Welcome to the TenForums @seba6560
When you say you have the exact problem could you share some details.
What is your PC, what type of connection are you using, what is the make and model of your NIC (adapter).
When did this start, what version build of Windows are you using?
When you said you re-install driver, was this the same driver version number or di you go back to an older driver and confirmed it installed correctly?
Might I suggest as this is a really old thread that you start a new one and outline the information I requested. Thanks
Ken
I have done every one of the fixes I have read on this thread, many others, and Youtube videos, and still have jack squat to show for internet access. No amount of flushing, uninstalling, network resetting, antivirus/firewall software deletion and on has helped. The only thing I have come across that appears to solve "IP does not have a valid configuration" issue is some form of Windows wipe or reinstall. These posts are old but this just happened on my laptop about 10 days ago after absolutely no issues since purchased a couple years ago. The issue occurs on both wifi and ethernet and on multiple networks which are working fine for multiple other devices. My problem is device specific to my laptop. I can not get a default gateway or a ping to work and I have tried all of the configurations I've read as well as the router settings themselves. Also of course tried DHCP numerous times. I think I am just going to have to reinstall the OS but has anyone solved this riddle when all of the recommended methods have failed? Thanks.
I spent hours screwing with this d mn problem. Issue was exactly as described on and on by shay but there was one new nugget here that saved the day!! From command prompt as administrator I dropped in this baby and it just said OK.. and it was! Thanks for that beauty. Nothing else helped.
netsh interface ip delete arpcache
