Since 8 Jan have had the diagnostic when running troubleshooter:

Wi Fi” doesn't have a valid IP configuration

I have the problem on 2 Lenovo laptops. One on Win 10 and mine on Win 11. A TP Link Deco router.

Also I have 2 Android phones and google cast using the wifi net, no problem on these.

Its intermittent, occasionally it “fixes” itself then 30 min later internet access fails again. The timing is not the same on the PCs, i.e. one might work and the other not. There is no known preceding event, no hw or sw changes.

I have executed every action described on the tech sites; reboots, resets, reloads, new SSID, driver updates etc; many times. Still have the problem.

I have not successfully set the IP addresses manually. My tech knowledge is not good enough to set a valid set of addresses.

Does anybody have ideas.

Have I given adequate information?

Many Thanks

Try this as a test
Open Notepad and type
Code:
@echo off ipconfig /release ipconfig /renew pause
Go to File-->Save as-->Save as type: select All Files from the dropdown
Save to your desktop -> File Name: IPconfig.bat
The next time you get that error
Go to your saved .bat and double click to run

IF that promptly fixes the issue let us know.

Thank you.

Its 8 am here. Had a thought during the night.

The deco router is a mesh system. In resetting the router I was resetting the node attached to the modem. Today I rebooted the node next to the PCs. Now WiFi and internet works again.

If it fails again I will use your suggestion.

Thank you

This suggests to me that the nodes and router have a bug in this mesh. I presume they are the same brand? What brand are they?
I would make them so that a reboot or reset of the router cause all the nodes to reboot or reset.

I agree. They are all the same brand (tp link) and type. In a mesh no one node is the router. The router is whichever node is ethernet connected to the modem. I assumed that in rebooting the connected node I was refreshing all nodes, not true.
