Nighthawk X10 AD7200 LAN Ports Not Working
Hi everyone. First time needing to post anything. Bought R9000 — Nighthawk X10 AD7200 Smart WiFi Router from Amazon on 2020-08-08. The ports stopped working after a storm we had. My Xfinity modem had...
Yep it ended up not being the ports, just everything that was connected. Replaced docking station, vpn hardware and NIC and it's working. Thanks for your help.
Yes.
Normally the Xfinity gateways are a combination modem/router. When your Xfinity gateway was replaced, was the new device configured in bridge mode? This is usually done to support a downstream router like your R9000.
What is the model number of your new Xfinity gateway?
Arris TG3482G
Thats a gateway router.
Your ISP Modem already has a built in router and wifi. This would be a double NAT (two router) condition which isn't recommended. This would be a double NAT condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAT

Couple of options,
1. Configure the modem for transparent bridge or modem only mode. Then use the NG router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the NG router gets from the modem. https://kb.netgear.com/25891/DMZ-on-NETGEAR-routers

3. Or disable all wifi radios on the modem and connect the NG router to the modem, LAN to LAN configure AP mode on the NG router.

The idea is to disable the router bit of your gateway, the TG3482G, so that the R9000 does the heavy lifting.

Tried michaelkenwa suggestion, no luck yet. One thing I did notice is my gateway is no longer 192.168.1.1 but 172.16.0.1. Any idea what that is about?
That could be down to the intervention of the Gateway. It is a sign of the dreaded double NAT that your TG3482G has wished upon you.
You may find that it has hijacked the 192.168.1.1 address and your Netgear router then opted for 172.16.0.1.
Thanks michael. I just turned off bridge mode. Here's what I found. All the devices wired to my nighthawk still won't work BUT I used my wifes laptop to do disable bridge mode and it is working wired to the nighthawk. I even moved it around to the other 6 ports and it worked each time.
Does that lead you to believe that the devices plugged in network ports were fried and not the nighthawk?
