New wifi hub router recently arrived two days ago, when I swapped it out for my previous talktalk router I have been unable to connect via Ethernet (wifi works)
I have troubleshooted my network and it shows "Ethernet doesn’t have a valid IP Configuration"
I have tried ipconfig/release + renew when comes up with "dhcp server unable to contact : timed out"
I have then tried ipconfig/flush dns + ipconfig/registerdns
I have uninstalled and reinstalled my network adapters
Updated all windows setting
checked DHCP is running
reset my network
reset my router
reset my pc
and still no sign of an Ethernet connection, please help

It seems that you have deleted your last post.
Why have you got a WAN port connected to a switch? The switch will only work when connected to a LAN port.

you said that all devices in the house are having the problem.. how are you running the network? are they all wired directly to the router or are you running a server off the router and using that as a DHCP server for the other machines?
I'd make sure you've not got a static IP address from the previous router, then try with a static IP to make sure there's connectivity over a wired connection, then check there's nothing set to disable DCHP or even the LAN ports, on the new router.

I don't know why you don't get the option to uninstall the driver, are you logged on in an Administrator account?
I don't recall you saying that there were multiple PCs affected by this. I will ask the OCEs to investigate.

I am running windows 10
With this issue effecting all ethernet devices in the house, would it be unprobeable that one pc would cause the issue / be able to fix the issue? wouldn't the issue lay within the router since its the central hub?

What version of Windows are you running then?

If you right click the adapter & select Properties
Go to the Driver tab & click Uninstall Device, then in the next window put a tick against Delete the driver software for this device.
Finally right click the network adapters section & select Scan for hardware changes.

Can you try removing the driver, it should be part of removing the adapter from Device Manager but you do have to request this? This is the action that resolved it on my PC.

Did you try what I suggested?
If you include any more screenshots, please make sure that the size in the Insert Photos tool is set to large. Your command line extract is way too small, when I try to enlarge it the text is totally blurred.

Still getting stuck here on the ipconfig/renew
I have tired to stop and start the DHCP server in services-
I have changed the permissions for access in regedit for DHCP and Tcpip but I still cant stop it and start it.

I did have a similar problem a few weeks back, when you uninstalled & reinstalled the adapter, did you remove the drivers as part of this?
Alternatively, when you ran the troubleshooter if you let it fix it, it will reset the network adapter.
