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!

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.
