I think you are looking for these dmesg lines:
I am struggling with the same issue for about two months now.
For me it must have started when I upgraded from Stretch to Buster and I did a firmware upgrade along that. Just to have everything latest. Before that I had my RPi 3 B+ running for months with no issue over 5GHz WiFi.
I tried reverting to Stretch realizing that all releases of Raspbian (since the release of RPi 3 B+) expose the same issue.
I have the same issue: WiFi freezes after some time on Raspberry Pi 3 B+ and I have to reboot the system to make it work again. Rasperry Pi uses built-in WiFi antena. Sometimes it takes few hours for issue to occur, and sometimes everything works fine for days. When it happens, I can see in
The same issue was discovered on Ubuntu (see report). One suggestion was to replace firmware that is shipped with the kernel by downloading and manually replacing brcmfmac43455-sdio.bin and brcmfmac43430-sdio.bin files. On Raspbian, firmware files are located in
I have the same issue on Raspberry 4.
Jan 30 00:46:26 masterpi kernel: [1320334.491483] brcmfmac: brcmf_sdio_hostmail: mailbox indicates firmware halted
Last two lines then repeat forever until reboot, which I need to do by switch-off/on as i use the Raspi headless.

Syslog sys regarding brcmfmac:
The issue comes up every now and then. Sometimes twice a day, sometimes it runs for days.
Would an external WiFi adapter bring more stability?
The device reboots and get connected again.

Any help or solution?
Hello all. Same issue here with a Raspberry pi 4 model B Rev 1.1 using the on-board Wifi. I am using this Raspberry as a WiFi access point. This issue happens one or two times after a day of normal use. Usually when here is a lot of traffic in the network (copying files, or reproducing video with the Chromecast). After this happens, all wifi-clients are disconnected and you have to power-off and power-on the Raspberry to get it working again.
You can find all the relevant information attached in this tarball:
Inside the tarball you can find: daemon.log, dpkg.log, hostapd.conf, ifconfig.log, kernel.log, lsb_release.log, lspci.log and syslog.log
Most relevant logs are located into kernel.log file, lines between 3538 and 3547. There is a time issue into this log file 20:56:37 --> 22:52:47 --> ... --> 22:17:05, not sure if it's related with the issue or not, but is strange that just in that moment of time happens the issue.
Here you can see the error:
Basically I have a bridge br0 between wlan0 and eth0. DHCP server is running on my home router connected to eth0. I am using hostapd to convert wlan0 into an Access Point. If you need more detailed information, I can provide it.
Hope this helps!
