3 years ago Just noting.. I've seen similar issues reported, but all seem to be related to using the Raspberry Pi as an access point of some sort. In this scenario, we're only connecting to wireless networks. I believe for that reason that this is a fundamentally different issue although the generic output seen is the same or similar.

3 years ago Can you retest with brcmfmac.debug=0x100000 in /boot/cmdline.txt (keep everything in a single line)? The firmware should log debug into the kernel log, including details of the crash.

3 years ago pelwell,
I put that in the cmdline.txt file and see it reflected in the dmesg output, but I don't see any additional debug information here. Should I be looking elsewhere?

Hello,
Describe the bug Raspberry Pi 3B+ wireless connection hangs or fails to connect initially to wireless network. We have reason to believe the issue is caused by environmental factors. Specifically, this is only happening at one site, although the firmware and versions involved are the same.
To reproduce We have thousands of deployed devices, a specific subset of which in the same physical space experience this issue regularly. I have remote access to the devices, and can typically reproduce the issue in less than 30 minutes on at least one device. I'm just not sure how to grab relevant/useful information about what's going on.
Expected behaviour Raspberry Pi connects to wireless network and remains connected.
Actual behaviour Raspberry Pi frequently fails to connect to wireless network and does not remain connected once a connection is established.
System
Which model of Raspberry Pi? Raspberry Pi 3B+
Which OS and version (
cat /etc/rpi-issue)? Raspberry Pi reference 2019-07-10Which firmware version (
vcgencmd version)? Aug 15 2019 12:06:42 Copyright (c) 2012 Broadcom version 0e6daa5106dd4164474616408e0dc24f997ffcf3 (clean) (release) (start)Which kernel version (
uname -a)? Linux ampxd-B827EBEB39A0 4.19.66-v7+ #1253 SMP Thu Aug 15 11:49:46 BST 2019 armv7l GNU/LinuxLogs Two scenarios: scenario (1) is when the device starts up but is not able to connect to wifi right off the bat, scenario (2) is where the device has started up and is connected to wifi but some random time later experiences an issue that causes it to disconnect.
scenario (1):
scenario (2):
Additional context Possibly relevant is that the devices are using Cisco 3602 APs. The area is somewhat wirelessly congested, but no more than we see elsewhere so I don't believe that to be relevant.
