26.1 Series / dhclient errors cause network to go down
February 15, 2026, 04:14:03 PM
After upgrading to 26.1.1, I had an issue where connectivity would drop a few hours after my router's boot. I reverted to 25.7. I recently tried again to upgrade to 26.1.2 and encountered the same issue. I looked in the logs and found this section of dhclient that I think is relevant. I've downgraded again to 25.7 and am no longer experiencing this issue. Can anybody help me troubleshoot?
