Computer not assigning itself IPv4 address after startup

This is a rather fustrating problem I've been dealing with as of the last few weeks.  I somewhat have a solution, but it is not one I can continue to do for several days at a time.  What is happening is I am getting the error "Wi-Fi doesn't have a valid IP configuration".  I've had windows10 for quite a while, and I know many people had this problem when they first got win10, but none of the solutions I've found on the internet have fixed my problem. (example of most common troubleshooting I am finding: https://www.drivereasy.com/knowledge/wifi-doesnt-have-a-valid-ip-configuration-on-windows-10-solved/).  Below are the most key points to my current experience with this error.

  • The problem exists only on one computer, not on any other computer running windows10 or any other opperating system.  Desktops, all in ones, laptops, smartphones, tablets, gaming systems, all of them still connect to the internet with absolutely no problems
  • The affected computer can still connect to the home network without any issues.  It logs in fine, detects and communicates with other computers, but cannot obtain internet access.
  • The problem exists both on wifi AND ethernet.  Plugging the computer directly to the modem exhibits the exact same behavior
  • Resetting the modem and the router does not correct the problem
  • Consolting the router shows my computer as having an unknown IP adress.  Further consolting the effected computer's properties shows no info assigned for IPv4.  What is shown is as follows:

SSID: (private info)

Protocol: 802.11n

Security type: WPA2-Personal

Network Band: 2.4GHz

Network channel: 4

IPV6: DNS servers: fec0:0:0:fff:1%1  (following 2 other entries, with 1% changed to 2% and 3%)

Manufacturer: Qualcom Communications Inc>

Description: Qualcom Atheros QCA61x4A Wireless network Adaptor

Driver Version: 4.0.0.262

Physical address (MAC): (will provide if needed)

  • Manually assigning an IPv4 address either does not fix the problem or I am unsure of what is the correct info to assign for my computer
  • my computer's drivers are fully up to date as of the time of this message
  • I have uninstalled and reinstalled programs attempting to diagnose if any of these are the problem, none seem to be at fault, nor can I identify any program or windows update occuring that might be responsible for the trouble (though if windows is doing more stealth updates I may be unaware of them)
  • Notably uninstalling and resinstalling Steam (game client) and prevenging auto-startup of the program allowed uninhibited internet access for 3 days, but the problem has returned again.  Steam has had no updates since the uninstall, nor has its settings changed.
  • Performing a system restore WILL restore internet access

There-in hits the most unusual nature of this problem - with no other adjustments to the computer, activating the system restore thus far has fixed the problem.  I've begun resorting to implementing a manual restore point to my computer any time I make adjustments to the computer or a program, and that restores my internet once I revert to one of these points.  However this is a long process and absolutely not something I can continue to do every day I need to use my computer, especialy when I am waking up early in the morning and need my computer before work.  Everything on my end points back to that IPv4 address that the computer is somehow losing the ability to assign for itself, and that my internet cannot provide access to without it.  How can we fix this problem?

    >>>>Please read the ENTIRE topic before responding<<<?????????????

    Don't ask for help and then be rude. I posted another option for you in same post.

    Did ya check your adapter and the IPV4.

    Did you check the drivers in device manager.

    You have to select the view tab and show hidden to show all network adapters

    Then see if the drivers are installed and no red or yellow flags exist.

    Next, did this start after the recent cumulative windows update?????

    Next, happens with Wi-Fi and Ethernet. Also beside checking the IPV4 for Ethernet, check your wireless adapter properties. Make sure one or both is not set to Static and on Automatic in IPV4 and IPV6 property settings

    Open modem settings and maybe delete old devices connected in past. Some IP providers will only allow you so many devices at a time or in a lifetime.

    The router assigns the IP address via DHCP.

    Make sure that everything is set to automatic under IPv4.

    In a cmd window enter the following and report back any error

    ipconfig /renew

    done as part of the troubleshooting exampled in my html address, does not work.  Everything is set to automatic, has no valid ipv4 assigned to it on startup until I've done a restore.

    Did you get an error or did the command succeed?

    If you do an

    ipconfig /all

    do you get IPv4 or IPv6 addresses?

    1. It's rude to only read part of the info and assume you know what the problem is and then offer support that has already been addressed, which wastes both our times. sadly this is expected results, and why I hesitated so many weeks to come to a forum in the first place. My reason for coming here isn't for random guesses, it's for someone to read the topic, realize they've seen this particular situation before and offer suggestion based on that experience that hasn't been tried yet.

    2&5) Yes, that's how as the title says, I know I'm not getting an IPv4 address assigned to my computer, addressed in bullet 5 and 6, though I suppose I need to be more specific in saying it was originally automatic then I troubleshooted manually assigning it, if that was not clear.

    1. Addressed in bullet 7, all drivers are up to date, again I guess needs to be more specific that no errors were spotted when I checked them for most recent driver.  What I did fail to specify was that I did delete and reinstall the drivers, but that was listed on the troubleshooting html that I liked as having done all of that already
    2. Bullet 8, this means no update occurred unless ninja updated by windows without user knowledge or permission, as they love to do lately
    3. This one I did fail to mention, done as part of troubleshooting from another source.  My modem allows for unlimited connections and I have already purged old computers.  My computer is also one of the first ones turned on in the day so if there was going to be spacing issues it would be for one of the later-activated devices, not my own.
