Unidentified Network through wired connection
Hi, I've been having trouble getting a wired connection with my Netgear Extender after we replace our Xfinity router due to the previous one being fried during a storm. It's been giving me Unidentified Network/ Ethernet doesn't have a valid IP configuration. My current setup is a Cisco Xfinity Modem/Router Hybrid Model DPC3941T in the main office on the main floor and the EX7300 Netgear Extender in the basement set up as an extender. WiFi is strong and is working normally, only the wired connection is giving me a hard time.
I have some knowledge/experience with troubleshooting and have already tried most of the basic troubleshooting steps to see what was wrong.
- Factory reset the extender / modem / router
- Replaced ethernet cable
- Used a switch between the extender and computer
- Did multiple ipconfig /release /renew with no results
- Did the netsh commands to reset TCP/IP reset
- Uninstalled the network driver / reinstalled with the current driver / tried using older driver
- Did sfc /scannow
- Gave the extender a static IP
- Gave the computer a static IP / 10.0.0.1 / 192.168.1.1 / 192.168.0.1 as gateways
I am getting a connection from the ethernet port on the EX7300 so it's not hardware related and more on the computer side. I've probably visited hundreds of sites and forums and tried the solutions there but my situation stayed the same.
Here's my ipconfig /all

If an extender is to be used to connect to a new router, the extender has to reset to factory default, and re-start the extender configuration process
I know, that's why it was the first troubleshooting step I did. I factory reset both the Router/Modem and the Extender multiple times in a span of this month and last month.
Can you run Ethernet to your Base router? Then configure the Extender as an Access Point, eliminating all this it works, doesn't work stuff..
