Ethernet doesn't have a valid IP configuration

Hello I keep having this ongoing issues where my network would completely drop and im not sure what is going wrong,

I have a Virgin hub 3 in modem mode connected to one router and the router to a range extender through wifi.

the issues affects the wired clients the same but some of them are able to come back online whilst others connected by an ethernet connection say Ethernet doesn't have a valid IP configuration.

I have tried all the netsh winsock reset to ipconfig release and renew, sometimes when completing ipconfig /renew it states the ip is already in use.

but the only thing that seems to fix it is to reset hub 3 and router to default settings.

I have ruled out the router as i have just changed from TP-Link Archer A7 AC1750 to TP-Link WiFi 6 OneMesh Router, AX1500

There has been some errors in the hub 3 error logs, if anyone has any idea on how to resolve this would appreciate it!

The 3 PCs connected via Ethernet, are they network cabled directly to your 3rd party Router
or via some other network arrangement ( E.g. via network switches / Powerline adaptors / Wi-Fi Repeaters etc ) ?

Take a look at the Hub 3 Upstream and Downstream tabs, these two pages often reveal service issues that is not reported in the Hub log.

When you say you "reset the Hub and TP-Link" did you set the Hub back to modem mode again?
Also, if in modem mode, can you confirm only one ethernet cable is attached to the Hub, and that is going to the TP-Link?

    I see so this was happening before the new router.

Are you sure the Hub is in modem mode? Does the TP-Link have a valid WAN IP address, e.g. 82.27.x.x ? Is the cable from the Hub in the TP-Link WAN port? What are the settings in the TP-Link for IP addresses, e.g. 192.168.1.1

  it is 100% in modem mode
  and the ethernet caples are in the right ports and on the router it is set to
  
  i believe the WAN IP is valid
  I looked at the Lan IP address is :
  I am not sure what is causing the issue but it worked with the same config for 5 years then suddenly started doing this this year

    That all looks fine. I can only suggest you start by disconnecting all your devices, and rejoin them one at a time, until you get the loss of IP. This may identify a "rogue" device causing the issue, e.g. managed switch ? I doubt if it is the Hub, as in modem mode it's only a "bridge" between VM and your TP-Link and has no other functions available.

Update to this... On 05/01/2025 though i do not understand why the culprit was the Wifi range extender after removing it from my network i have had no more problems at all.
