WiFi not working on one device
 

I had to install the new type phone adaptor into my hub yesterday then reboot the hub.
All appeared to have gone well, my desktop via Ethernet was fine. Two different tablets and two smartphones reconnected to the wifi network perfectly.

today I have just tried to use our Win 10 laptop and get 'Unidentified network, no internet access' on the taskbar.

Running the troubleshooter for network status throws up the problem as 'WiFi doesn't have a valid IP configuration'.

I have tried a few simple things like rebooting hub and PC, ipconfig/flushdns and reset network adaptors without any joy. :(

Any suggestions welcome.

Re: WiFi not working on one device
 

Could try to forget device / network, refresh, click on your wifi name, enter your wifi password. ?

Re: WiFi not working on one device
 

Think I may have already done that as well..

Re: WiFi not working on one device
 

Have you tried ipconfig /release and ipconfig/renew?

Found this on a search.....

1. Press Windows+X and select Windows PowerShell (Admin).

2. Run each of the commands below, pressing Enter after each line and waiting for the process to finish:

netsh winsock reset catalog
netsh int ip reset

3. Exit the PowerShell window and restart the computer. If a corrupted TCP/IP stack was at the source of the error, you should be able to connect online without problems.

Re: WiFi not working on one device
 

I found those as well, tried them al without success, will go over them all again, also mentioned drivers as a possible cause?

Re: WiFi not working on one device
 

Uninstall / reinstall the network adapter? Re install drivers for it.

Pull the plug on the router for at least a minute or 5?

Check if Network Service Is Running?

Reset Firewall and AV?

Network reset within windows?

Tricky one that, should be a straight forward fix but you've seem to have tried everything.

Re: WiFi not working on one device
 

Going out for a couple of hours, will get back on it later.

Re: WiFi not working on one device
 

Back again, have uninstalled WiFi adaptor in Device Manager, rebooted and reinstalled drivers with no success.

I have now plugged an ethernet cable between the hub and laptop and still get an 'Unidentified Network' message.:(

Try everything on this page.

Re: WiFi not working on one device
 

Had enough for now, will try again tomorrow although I have already done most of the things on that list.

Thanks for trying to help.

Re: WiFi not working on one device
 

I had an issue a few weeks ago with my work laptop (windows 10). I got a new router from Sky and to save me changing the WiFi details on all the bits of kit round the house I decided to just change the network name and password on the router.

All was good until the next day when I turned my laptop on and it just wouldn't connect to the WiFi, and whatever I did made no difference. I swapped the router back to the old one and everything connected no problem. Sky wanted the old router back so keeping it wasn't an option so in the end I reset the new router, kept the default network name and password and everything (including my work laptop) connected no problem.

Re: WiFi not working on one device
 

Still plugging away with this.

Update: I found that when I tried to run ipconfig/release or ipconfig/renew they failed due to ‘Media disconnected’ warning???

Now looking at how to solve Media Dissconneted errors.:(

Re: WiFi not working on one device
 

Some info on that here....

https://www.drivereasy.com/knowledge...ed-in-windows/

(Just don't bother with any 'driver easy' software).

Re: WiFi not working on one device
 

I have been working my way through that and several other pages without success so far. Nextt step is to try and update the wifi adapter drivers but not as easy without internet. Trying to find it on the Intel drivers site atm.

---------- Post added at 13:46 ---------- Previous post was at 12:36 ----------

Still no joy, downloaded the latest drivers from intel but PC insists it is using the latest ones.

My real problem/ question is chicken and egg. Is the Media Disconnected the cause of the problem or is it No valid IP configuration??

Would I be correct in thinking that the fact that the fault is exactly the same on both wifi and ethernet means that the wifi adapter drivers are not the cause of the problem?

Re: WiFi not working on one device
 

I take it you've tried the below in the order stated?

In the search box on the taskbar click Start, type command prompt, right-click the command prompt result and then select Run as administrator and confirm.
At the command prompt (decline restarting your machine until you have entered the final command):
Type ipconfig /release and press Enter.
Type ipconfig /flushdns and press Enter.
Type ipconfig /renew and press Enter. (This will stall for a moment.)
Type netsh int ip reset and press Enter. (Don’t restart yet.)
Type netsh winsock reset and press Enter.
Now restart your machine

Re: WiFi not working on one device
 

Yes, the problem is that all ipconfig commands fail with the Media disconnected warning.
I have gone through all the online suggestions to rectify that fault to no avail.:(

Other than reset network settings on this link..

Would be easier to do a clean install of windows. That said, it could be the router that's the problem and not the PC. Can you reset to factory settings on the Hub itself using the pinhole at the back?

Running out of ideas now, something doesn't add up.

Re: WiFi not working on one device
 

you would try an in place reinstall using the upgrade option surely before a clean install ?

Re: WiFi not working on one device
 

Yeah you're right, whatever or whichever is best. Probably it's just me as I class any re-installation of windows as a clean install, and I admit it's wrong. It's because I use a clean 'image' back up of windows which only takes me 5-10 minutes to revert to. So I very rarely if ever do the upgrade way to reinstall if there's a problem.

Re: WiFi not working on one device
 

I have used backupper for years and keep a regular known good full system image with all install

Re: WiFi not working on one device
 

Iadom, did you try a factory reset of your Hub? Using the pinhole at the back and holding it in for at least 10 seconds?

Re: WiFi not working on one device
 

If the hub/router was the problem why does wifi work perfectly on four other devices and why am I getting Media Disconnected warnings whenever I try to use ipconfig commands?

Have done a network reset three times.

Laptop is around 7 years old now and flags up as not suitable for Win 11 upgrade. And not easy to do upgrades without internet connection.

Re: WiFi not working on one device
 

Not sure but things like this tends to be a process of elimination. So it's always worth a try just to rule it out.

Usually for that error then...

netsh winsock reset catalog
netsh int ipv4 reset reset.log
netsh int ipv6 reset reset.log

Followed by checking if the network adapter is enable, would usually fix the problem of the media disconnected error.

Re: WiFi not working on one device
 

Maybe obvious, but the thing that triggered this off was the introduction of your phone to the hub? Are things in the right sockets does the phone work? Disconnect the phone from the hub reboot and try?

Re: WiFi not working on one device
 

Does the laptop connect through a cable?

Re: WiFi not working on one device
 

The laptop will not connect via wifi or ethernet cable.

Did unplug the phone .

Have gone through the whole of the reset Winsock procedures two or three times..

Re: WiFi not working on one device
 

Apart from factory reset of your hub which is still worth a try, the only other option I can see is to repair windows from settings (system / recovery).

Back up any important files etc to another partition, external or disks etc.

Re: WiFi not working on one device
 

Surely any problems on the hub would still not cause the Media Disconnected error message on the laptop. Apart from the two tablets and two smartphones we have a Portal, Echo Dot, CCTV system and a couple of TV’s all connected to the hub and all functioning correctly.

Irrespective of the hub I should still be able to use ipconfig commands on the laptop.

Re: WiFi not working on one device
 

Can you use your phone as a wifi hotspot and see if the laptop connects to that?

Re: WiFi not working on one device
 

Just looking at this option I cannot see a recovery option in Settings / System?

---------- Post added at 11:32 ---------- Previous post was at 11:29 ----------

Will have a look at that but as it will not connect via Ethernet either I doubt that will work.

Re: WiFi not working on one device
 

This is a good test to see if it’s the laptop…

Re: WiFi not working on one device
 

If it connects to your phone's wifi hotspot then it'll be the router / hub that's the problem. If it doesn't then it'll be your laptop.

Re: WiFi not working on one device
 

Tried using phone as hotspot, connected but exactly the same no internet

Re: WiFi not working on one device
 

Looks like it’s a laptop problem

Re: WiFi not working on one device
 

It has always registered as ‘connected’ to the wifi but reports unidentified network, no internet connection. The exact same message when using ethernet or phone hotspot.

I am convinced the Media Disconnected error is a the root of this problem

Re: WiFi not working on one device
 

Have a look in the control panel device manager and see if anything is being flagged up (yellow exclamation mark).

Re: WiFi not working on one device
 

I have been certain of that for some time and am sure this Media Disconnected error message is to blame. I have just gone through the reset Winsock, ipv4, ipv6 routine again which does complete successfully but I still cannot get any ipconfig commands to work.:(

Re: WiFi not working on one device
 

Worth checking if any system errors too.

Open Start.
Search for Command Prompt, right-click the top result, and select the Run as administrator option.
Type the following command to repair the Windows 10 system files and press Enter: sfc /scannow

This can help if ipconfig doesn't work or run as it can fix them. After you've ran it, then try the ipconfig commands (as admin).

Re: WiFi not working on one device
 

Nothing flagged up.

Re: WiFi not working on one device
 

Could it be the antivirus on the laptop preventing access for some reason ??

Re: WiFi not working on one device
 

Just running scannow from Power Shell window.

Disabled AV and Firewall without success.

Re: WiFi not working on one device
 

You could try a DISM repair with a Win 11 iso

https://www.windowscentral.com/softw...-on-windows-11


But personally I would be trying a repair install following this method

https://answers.microsoft.com/en-us/...7-f40096ec3085

You will need a windows 11 iso so you will need another machine to create one

Re: WiFi not working on one device
 

Would that work with this laptop as it does not meet Win 11 specs?

---------- Post added at 13:40 ---------- Previous post was at 13:38 ----------

Scannow shows, ‘ Windows Resource Protection found corrupt files but was unable to fix some of them’.

---------- Post added at 13:50 ---------- Previous post was at 13:40 ----------

Downloading an ISO on desktop, getting desperate now, the throw it against the wall option is looming large. :D

Re: WiFi not working on one device
 

Did you retry the ipconfig commands?

You can use a windows 10 ISO, you're not installing it but using the repair / DISM aspect from the disk image. Normally you use it when you're online, but as you're not you have to use an ISO.

Or you can repair using the ISO. (upgrade option) - Video included in link.

Re: WiFi not working on one device
 

Tried ipconfig several times, still no joy. Win 10 ISO upgrade nearly finished loading onto usb drive.

May have to leave it till later now, even in my dotage (75) I still have to get my two or three games of squash or racketball in.:cool:

Re: WiFi not working on one device
 

No problem, try the repair option first as should be easier to do. DISM can go a bit wrong.

Re: WiFi not working on one device
 

Just to be clear, you didnt change anything on the router, and the laptop connected to it via WiFi ok, before you rebooted it ?

Presumably you must have rebooted it on previous occasions, and never had an issue reconnecting your laptop ?

If so, whats changed since then ?

Re: WiFi not working on one device
 

Not changed anything but tbh the laptop has been a bit up and down recently. I don’t use it that often it’s my wife’s PC. Booting up has been slow and emails have sometimes been slow at downloading.

Re: WiFi not working on one device
 

How old is the laptop, and has it been fully checked with an anti-virus and malware checker recently?

Re: WiFi not working on one device
 

It’s around 7 years old, up to date AV and Malwarebytes installed and scanned regularly.

Just about to get going with ISO repair/ upgrade.

---------- Post added at 12:29 ---------- Previous post was at 10:34 ----------

Win 10 install plodding along slowly. One quick question, during the initial preparation it mentions the need to access up to date components on line, how can it do this as the laptop has no connection?

Re: WiFi not working on one device
 

It might well have one once it gets to that point

Re: WiFi not working on one device
 

:cool::cool::)

Success. I got a bit worried when the update got to 90% then stalled there for nearly 30 minutes.

Full wifi access now restored.

Many thanks to everyone who participated in this thread, hopefully it may help someone else in the future.
