Welcome to the new AT&T Community
We've got a fresh look! Take the tour to see what's new.
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.
Unfortunately rebooting does not appear to work.
I did a "Reboot system" from the Diagnostics pages, but both entries remain.
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.
