Wireless reconnect regressions after an image upgrade can come from changes in power management, regulatory domain settings, or network profile priority. 1. Useful diagnostics Export the active NetworkManager connection, check journal logs around resume, and compare power-save related settings before and after the upgrade. 2. Recovery options If the regression blocks field testing, pin the previous image temporarily while you isolate whether the issue is firmware, kernel, or user-space configuration.
