Ethernet ports show activity, but are not allowing connection to the internet

Question

Today when I connected to my docking station, I discovered I could not connect to the internet. First assumption was a Comcast outage which is often solved by the standard turning off of the modem and router, waiting a minute and turning back on.

I discovered that while I could connect to the router's WiFi, I could connect to the internet. I logged into the router via wifi, and indeed confirmed that the only connection method were all by wifi. All of my extenders are connected by ethernet (so can't connect to them via WiFi and get to internet). Laptop at my desk is connected by ethernet (well, MoCA to Ethernet), my gaming console is ethernet. Overall, about 17-ethernet connections throughout my network. None of them are working.

Everything I Google around 'router WiFi working but Ethernet not' tries to trouble shoot the computer connecting. In my case, it seems everything 'can' connect to the router, but it can no longer reach the internet. I'm not sure if something is up with my LAN settings, DHCP, etc. Nothing has changed that I know of since yesterday.

No idea where to go from here to triage. I'm using a Netgear R9000 x10.

Yep, it's a new one by me for sure (ok, I'm not a guru, so there's lots of new things by me 🙂 - but in the scheme of things, seeing activity but not having connectivity seemed pretty odd).&nbsp;And so . . . yesterday morning when I went to get to doing a full reset . . . it was all working.&nbsp;Which is about as perplexing since these things usually don't fix themselves.&nbsp; I'm of course going to monitor it the next few days and likely going to do the full system reset just to be sure.&nbsp; My best guess is that there was some type of conflict in the assigning of IP addresses.&nbsp; Something in the DHCP setup?&nbsp; Maybe caused by a rapid on/off of the router (I have been having some power fluctuation problems).&nbsp;I want to assume 'user error' or the like as well.&nbsp; Maybe time will tell.&nbsp;Thanks for the assist.

What firmware is on the r9000?
what modem/gateway is it connected to?&nbsp;
Are any devices connected directly to the router or are they running through switches/moca adapters?

Thats interesting that they're showing connected but no data packets transferring.&nbsp;
Did you try factory resetting and reinstalling?&nbsp;You could also try reinstalling the firmware then doing the factory reset (or start with that first).&nbsp;
IF something is corrupt in firmware, the firmware reinstall covers that. IF something is corrupt in the settings, the reset should cover that.&nbsp;
