Problem with wireless adapter / no valid IP configuration

My desktop is unable to connect to the internet.  All my other devices have no problem connection to the wifi.  I have been sent an Ethernet cable to connect directly but, this has not helped.

The troubleshooting problems read:

- Problem with wireless adapter or access point

- "Wi-Fi" doesn't have a valid IP configuration.

 

My first search on the forum showed a solution to systems recently updated to Windows 10.

Some Windows 10 users are experiencing difficulty connecting to the internet after installing the latest update.

In most cases the IP address is now starting 169…

We have found that by flushing the DNS and renewing the DHCP lease it resolves the issue.

It can be done by opening the command prompt by clicking on the following:
•Click Start
•Click Run
•Type in CMD and press Enter.
•This should open up a command prompt window.
•Now type in ipconfig /releaseand press Enter.

Finally, type in ipconfig /renew and press Enter

You should have a new 192… IP address.

The command box now reads that no operation can be performed on Ethernet, Local Area Connection, Bluetooth and that the system cannot find the file specified for the wifi. 

Please can someone point me in the right direction?

Re: Problem with wireless adapter / no valid IP configuration

Hello,

I'd be happy to help you out; and I'd like to better understand your current PC status so I can provide the best recommendations.

Is this a Windows 10 machine? Home or Pro?

From that command box you have, can you type the following command and provide the results here? The command is ipconfig /all

I see the rest of the devices you have are not encountering the same issue. Are any of those Windows (not 10) as well?

What Antivirus do you currently have installed?

Re: Problem with wireless adapter / no valid IP configuration

Is there more to fix problem.

I am getting No valid IP configuration

Solved by flushing using ipconfig.

 

However next time I use laptop 

problem comes back No valid IP configuration

again solved by flushing using ipconfig.

 

This has now happened at least 4 times.

Re: Problem with wireless adapter / no valid IP configuration

I'm having the same problem - every time I switch on my desktop it can connect to the router, but not the internet, can't even ping 8.8.8.8, so there's definitely some kind of gateway problem rather than just DNS, and then an ipconfig release/renew fixes it. Wireless devices all work fine.

Re: Problem with wireless adapter / no valid IP configuration

So my internet connected TV is now doing the same thing (although I can't do an iconfig on that, so I have to fiddle around with the network settings until it refreshes them) - which implies it's definitely something going on with the VM router.

before I renew my ipconfig it won't let me 'release', and it says this:

194.168.8.100

Afterwards it says this:

Now, I do have a slightly complicated network configuration because the VM router WiFi was proving so unreliable that I had to reboot it on a weekly basis to get it to connect. I have disabled it and installed an Archer C2 WiFi router (Uptime 232 days without a hitch!) which runs a separate IP subnet, and treats the VM router (with a 10.0.0.x subnet) as its 'internet' connection, but the IP range for the Archer is 192.168.1.x (so not picking up an IP from that above),  interestingly the PC is wired to the VM router, the TV to the Archer, so something properly strange is going on - and I've not changed anything in my network configuration in about a year.

Given it's multiple devices with different OSs, and I'm not the only customer, is it possible VM have dropped an update to their routers which has borked something? I've got one of the (I think) older superhubs (settings say V2.39.02).

Re: Problem with wireless adapter / no valid IP configuration

Ipconfig works around the problem , does not fix.

 

The problem can be fixed by simply do a restart ( not shutdown )

Re: Problem with wireless adapter / no valid IP configuration

Looks like it is definitely a Windows problem: http://www.theregister.co.uk/2016/12/12/ongoing_windows_8_10_dhcp_problems_affecting_all_isps/

...I've gone with a static IP until Microsoft come up with a fix.

Re: Problem with wireless adapter / no valid IP configuration

Have you tried using the following methods to gain IP configuration? You should give it a shot to see how it works.
