removing stale DNS entries from the 2wire gateway

I have a stale DNS entry for my laptop's wired ethernet on the gateway.   The laptop is on wireless right now, but the gateway is giving out the wired IP address for my other devices, which means that they cannot connect to the laptop.

 

How can I remove this stale DNS entry?  An automatic method would be best, but a manual method would be fine as well.

Then the only thing left is to factory reset the modem. Use the last button on the following page:

Rebooting the gateway should clear any lingering entries.

Unfortunately rebooting does not appear to work.

 

I did a "Reboot system" from the Diagnostics pages, but both entries remain.

On the following page, there is a "Clear List" button under the Devices section. This should clear all devices that don't have a firewall entry. Be aware that it clears all device-specific configuration, including DMZPlus settings, IP address assignments, etc.

Yes, factory reset appears to be the only way to get rid of bad DNS entries, as confirmed by AT&T Tier 2 support.

 

It is rather stupid to not have a better way to clear bad DNS entries.
