My router doesn't serve DNS on Ethernet ports

I have multiple devices connected to my router. One is a wireless AP, that works fine all devices connected to the AP work fine. However devices connected directly to the router have stopped working. They receive a DHCP lease but do not receive DNS answers and setting the DNS servers manually also doesn't work. When I log into the router I see the following. Interfaces Interface Status Active Devices Inactive Devices Ethernet Enabled 1 1 I am not sure why it shows 1 device as inactive. I have totally reset the router but that didn't change anything. The router is BGW210-700. Looking at home network --> IP Allocation it says status "off" how do I change this ?

The problem ended up being the netgear switch that sat between my office and the ATT router after testing networks and ports on router I rebooted the netgear switch again and everything started to work again.  Strangely enough the router would let DHCP traffic go through sometimes so you would have an IP but you couldn't actually use the computer since all DNS traffic was getting dropped.

Let's make sure all your devices are connected properly, @asadba

 

If you haven't already, we recommend factory resetting your gateway to rule out any 3rd party equipment or custom settings that may be causing this.

  1. Press and hold the gateway Reset button for at least 10 seconds. If you let go before 10 seconds, the gateway will reboot, but it won’t reset.
  2. Wait until the gateway restarts and all the status lights are lit. 
  3. See if the Broadband or Service status lights are solid green. If so, the reset worked.

This will get rid of any settings you may have changed, so we recommend writing down the settings you'd like to keep.

 

Please let us know if this helps! If not, we may need to take a closer look at your equipment!
