Debug Random Disconnects on OpenWRT

My fleet of CPEs and access points is running a freshly-updated, custom-built OpenWRT image, and ever since the upgrade the radios keep dropping clients at unpredictable intervals. One moment stations associate, the next they are kicked off and reconnect seconds or minutes later. Wired traffic is solid, so the fault is isolated to the wireless stack or its configuration. I need someone who knows OpenWRT internals—hostapd, netifd, wpad, mac80211, ath10k/ath9k debugging, the lot—to dig into the logs, capture traces, and tell me exactly why these disconnects are happening. Expect SSH access to a lab unit as well as copies of the build config and recent commit diff from the image builder. What I consider a successful engagement: • A concise report identifying the root cause (driver bug, mis-match between kernel and wireless drivers, bad regulatory domain, mis-timed roaming settings—whatever you find). • A working fix or clear configuration change I can deploy to every node. • Steps I can repeat after future upgrades so this doesn’t re-appear. If you can drop in custom patches, rebuild the firmware, or guide me through buildroot changes, even better. I’ll supply real-time logs (logread, dmesg), wireless captures, and access to remote serial consoles as required. Let’s get these radios stable again.
