Debug Random Disconnects on OpenWRT

@gotucat

Hi, I reviewed the OpenWRT upgrade issue where Wi‑Fi radios randomly drop clients while wired stays stable, and I’ll focus on identifying the exact wireless-stack cause after the custom image update. I’ll analyze logs and traces from logread, dmesg, hostapd/wpad, netifd, and mac80211, then correlate it with driver behavior for ath10k/ath9k, regulatory domain, and roaming/config timing to find the root trigger. I’ll produce a concise root-cause report, a working fix or deployable configuration change, and repeatable steps for future builds, with clean, well-documented guidance. Let’s discuss here now.

@Shrutibimpl

Hello, I can analyze your OpenWrt wireless stack logs and identify the root cause of your radio client disassociations. My plan is to log into your lab unit over SSH and analyze logread and dmesg outputs to isolate deauthentication reason codes and ath10k or ath9k driver tracebacks. I can review your recent OpenWrt commit diffs and build configuration files to spot regressions in mac80211 wireless patches wpad settings or kernel drivers. I can capture hostapd debug logs and iwmon wireless traces to check for beacon timeouts Protected Management Frame mismatches or DFS radar false triggers. Once I isolate the issue I can provide a kernel or hostapd configuration fix to stabilize your wireless fleet. In a past project I diagnosed mac80211 and ath10k driver disassociation bugs on custom OpenWrt access point images. 1) Which specific wireless chipset like ath9k or ath10k is running on the affected access points? 2) Are the disassociations occurring on 2.4 GHz 5 GHz or both radio bands? 3) What OpenWrt release branch like 22.03 or 23.05 was used as the base image for your build? Thanks, Bharat

Hi, I am an embedded systems engineer with over 16 years of experience developing and debugging Linux-based networking products, including custom OpenWRT firmware and wireless systems. I have extensive experience tracing intermittent Wi-Fi faults across hostapd/wpad, netifd, mac80211, ath9k/ath10k drivers, kernel logs, regulatory settings, roaming behavior, and build configuration changes. I can investigate the supplied lab unit, correlate logread and dmesg events with wireless captures, and compare the updated image configuration and commit diff to isolate the regression. I will provide a concise root-cause report, a tested configuration change or source patch, and repeatable validation steps for future upgrades. If necessary, I can also assist with Buildroot changes, firmware rebuilding, deployment guidance, and remote serial-console debugging. Are all affected devices using the same wireless chipset, and is the previous stable firmware image available for comparison? I have also supported consumer-grade embedded products from concept through production, so I can help ensure the fix is suitable for fleet-wide deployment rather than only the lab unit. Please contact me to discuss details.

✋ Hi, the key here is isolating whether the disconnects come from hostapd/wpad behavior, driver regressions, regulatory settings, or a kernel/firmware mismatch introduced by the new image. I’d compare logs and traces against the previous stable build, then narrow the failure path through hostapd, mac80211, ath10k/ath9k, and netifd before applying the smallest reliable fix. Do the disconnects affect all radio chipsets in the fleet, or only specific ath9k/ath10k-based units?

@Hrolgar

The choice that actually decides how I'd start is whether the disconnects come from the radio itself or from what the radio is being told to do, and those two point at completely different first moves. A firmware crash loop in ath10k/ath9k shows up as restart lines in dmesg right next to the drop, repeatable independent of client behavior. A roaming or regdomain misconfig shows up as deauth reason codes in the mac80211 log tied to specific clients or channels, and it's a config diff against the pre-upgrade build, not a driver problem at all. Wired staying solid the whole time argues against a shared hardware fault, which is what points me at the radio stack and hostapd/wpad first rather than netifd or anything downstream. I'd pull logread and dmesg off a few CPEs during a live disconnect window before touching the lab unit, since the fleet-wide pattern tells me more than anything I can reproduce on a bench. Then a straight diff of hostapd, wpad and netifd configs against whatever shipped before the upgrade, since a custom image is exactly where a default got quietly overwritten. M1: log collection across a sample of affected CPEs plus firmware/deauth triage to isolate crash loop vs config cause, $215, 2 days. M2: root cause confirmed on the lab unit, fix or config change built and validated against reproduced disconnects, $220, 2 days. M3: fleet-ready config/image change, plus a repeatable check script for future upgrades to catch this before rollout, $215, 2 days. That's priced off the brief as posted, six days across the three stages. The one thing that could move it is how many firmware/hardware variants are actually in the fleet, since a mixed ath9k/ath10k deployment means the crash-loop path (if that's what it turns out to be) needs validating per chipset, not once.

I will then deliver a solution or recommend configuration changes to prevent future issues, integrating custom patches if needed. My goal is to restore network stability and establish long-term performance optimization through proactive maintenance and ongoing consultation.

@ahmaddar2970

I can help diagnose and stabilize the OpenWRT wireless stack across your fleet. Your symptoms point to a fault in the wireless path rather than the wired network, and I’d approach this systematically: compare the upgraded build config against the prior known-good image, inspect hostapd/netifd/wpad behavior, review dmesg and logread for driver resets or association churn, and correlate packet captures with radio events. I can then isolate whether the issue is coming from mac80211, ath10k/ath9k, regulatory settings, roaming parameters, or a build mismatch introduced in the custom image. If the root cause is configuration, I’ll provide a precise deployment-ready change set for all nodes. If it is a driver or firmware regression, I can help narrow the offending commit, propose a patch-level fix, and outline repeatable buildroot steps so the problem does not return after future upgrades. I’ll keep the deliverable focused: root cause, remediation, and a validation procedure you can reuse on later firmware releases.

@EricLeroyDev

Hello, A custom OpenWRT rebuild that keeps clients solid on wired but drops stations at random on the radios usually points to something narrow, and the good news is your logs will tell the story before anyone touches the firmware. My instinct is to start from logread and dmesg plus a short 802.11 capture, and isolate whether the culprit sits in hostapd, mac80211 or the regulatory domain, rather than assuming a driver bug straight away. To point you in the right direction, three things would help: 1. Which OpenWRT version and wireless driver are on the fleet (ath10k-ct, ath9k, mt76)? 2. Do the drops hit every band and channel, or one in particular, and do they track client load? 3. Is fast roaming (802.11r/k/v) enabled in your config? Based on your answers I would expect this to land roughly in the 290 to 540 EUR range, with a firm figure once the scope is clear. Happy to discuss whenever suits you. Best regards, Eric

@dinobartolome

Your symptoms point to something in the wireless stack that changed between builds - could be a hostapd config delta, a driver version mismatch with the new kernel, or a regulatory domain issue messing with DFS channels. The fact that wired traffic is solid narrows it down fast. I run Linux servers and embedded Linux systems daily. I've done headless Raspberry Pi deployments with systemd services, network architecture with VLANs and PoE switches, and I'm comfortable living in SSH sessions parsing logs and chasing down why something broke after an update. The diagnostic process you're describing - logread, dmesg, wireless captures, diffing build configs against the last known-good image - is exactly how I'd approach it. Pull the commit diff from your image builder, compare the wireless driver versions and hostapd config against the previous working build, capture association and deauth frames to see what's actually happening on the air. That said, deep mac80211 and ath10k driver-level patching isn't part of my daily work. If this turns out to be a kernel driver bug that needs a custom patch rebased against your buildroot, you might want someone who lives in that code full time. But if it's config, regulatory, or a package version mismatch - which covers most post-upgrade wireless breakage - I can find it and fix it. Want to start with a quick SSH session so I can look at your logs and build diff?

Hi, saw your post about random client drops on your OpenWRT fleet since the image rebuild. The hard part is telling a driver regression, like an ath9k or ath10k firmware issue, apart from a bad regulatory domain or mistimed roaming config, so I would start by diffing the build config against a known good image. Do you have logread and wireless captures from before the upgrade? We have traced similar mac80211 and wpad disconnect bugs on embedded Linux gear by correlating kernel logs with driver traces. Happy to start on the lab unit as a small milestone so you can judge the root cause first. Regards, Hassan

@mengw3

I have spent 20+ years in embedded and RF work, the last several years deep in OpenWRT builds - hostapd/wpad configs, netifd, mac80211, and driver-level debugging on ath9k and ath10k chipsets. I have traced disconnect bugs to regulatory domain mismatches, beacon timing, and kernel/driver version skew after buildroot upgrades, so this pattern is familiar. The hard part is telling a driver regression apart from a config drift the rebuild introduced, since both look identical to a client on the ground. - Pull your commit diff and build config first, diff wpad/hostapd/mac80211 package versions against the last known-good image - SSH into the lab unit, run logread and dmesg while forcing disconnects, capture frames in monitor mode with tcpdump/tshark to read deauth/disassoc reason codes - Check regulatory domain and channel/DFS settings, CAC events after upgrades often look like random drops - Compare roaming/timeout params like ap_max_inactivity against the old build defaults - If it is a driver bug, bisect ath9k/ath10k firmware and kernel commits between the two builds You get a short report with root cause, a patch or config diff to push fleet-wide, and a checklist to run after future upgrades. Do you have kernel/driver package versions for both old and new images, or just the diff? I can start right away.

@eshmumkhan

Hello. My name is Eshmum, and I am an embedded Linux and wireless networking engineer with over 7 years of experience debugging OpenWRT, hostapd, and mac80211 drivers, and I have successfully resolved similar random disconnect issues on ath10k and MT76 platforms by analyzing logs, capturing wireless traces, and applying targeted configuration or driver patches. I understand your fleet of CPEs and access points is running a custom OpenWRT image where wireless clients disconnect unpredictably while wired traffic is solid, and you need someone to dig into the logs and traces to identify the root cause. My approach will start by analyzing your logread, dmesg, and wireless captures to identify the disconnection reason code and any related driver or hostapd errors, then I will apply a working fix whether it's adjusting hostapd parameters, applying a kernel patch, or rebuilding the firmware with corrected wireless drivers. I will provide a concise root cause report, a deployable fix, and clear steps to prevent recurrence after future upgrades. I am ready to start immediately. Best Regards. Eshmum.

@haseebs74

Hi, I can troubleshoot the OpenWRT wireless instability and identify the actual root cause rather than applying random configuration changes. I’ll review the build configuration and recent commit differences, inspect logread/dmesg and hostapd/wpad output, and correlate disconnect events with driver, kernel, mac80211, regulatory-domain, roaming, and interface behaviour. I can also use wireless captures and remote serial-console data where needed to narrow down exactly what is triggering the client drops. Once the cause is confirmed, I’ll provide a tested configuration fix or patch and, if required, help rebuild the OpenWRT image with the correct driver/kernel changes. I’ll also verify the fix on the lab unit before recommending deployment across the fleet. The final deliverable will include the root cause, exact changes required, deployment steps, and a repeatable diagnostic checklist for future firmware upgrades. I’m comfortable working over SSH on Linux/OpenWRT systems and can start with the lab unit, build config, and commit diff immediately.

@Digitalizers010

Hi, clients dropping off your OpenWRT fleet at random since the image rebuild. The answer is usually in the deauth reason code. How we'd work it: hostapd logging turned up on the lab unit so every disassoc lands in the log with its reason code, plus a monitor capture that says whether the frame came from the AP or the client. Then the build diff, kernel against mac80211 skew, then the regdomain, since a channel that turned DFS does exactly this. Is it ath9k or ath10k on these radios? Our Linux work is mostly this, reading kernel and daemon logs until the cause is proven. Happy to start on the lab unit and report before anything hits the fleet. Regards, Digitalizers
