Hi @fhunleth
I am a @pojiro's friend who reproduced this issue :)
As just FYI, I've confirmed new firmware also worked well and fixed this issue in my environment. I'm really thankful to you!

Great! Thanks for verifying that it works. Once I verify that the RPi Zero still works, I'll merge and start the process of getting new Nerves systems out. Shouldn't be much longer!

I think that the firmware is out of date. Due to a missing firmware file and looking out-of-date, I switched wifi firmware repositories in this release to the linux-firmware
one. I assumed that the linux-firmware
files would be more current since they had the missing file, but they are not. It looks like the latest firmware files from the Raspberry Pi Foundation are maintained at https://github.com/RPi-Distro/firmware-nonfree/tree/master/brcm. They have recent timestamps so I'm hopeful. It's getting late here, but my next try would be to try these by putting them in /lib/firmware/brcm
and seeing if that works.

Thanks for reporting this! I am preparing an update to the Raspberry Pi 4 that fixes GPIO pullups and adds GPU support via DRM, so this is timely. Perhaps it is as easy as getting the latest firmware from the Raspberry Pi OS or perhaps the linux-firmware
project has a fix.

@pojiro Could you try this firmware? It has the new WiFi firmware and I hope that it works for you!

@fhunleth I tried the fw and I confirm it works with 5GHz WiFi AP which is I mentioned earlier.
I see RingLogger, it seems no errors, no disconnects so far, seems nice :) .
from nerves_system_rpi4.
I'm trying to reproduce, but 5 GHz seems to work for me. Here's my connection to my test AP:
iex(18)> VintageNet.get_by_prefix(["interface", "wlan0", "wifi", "current_ap"])
[
{["interface", "wlan0", "wifi", "current_ap"],
%VintageNetWiFi.AccessPoint{
band: :wifi_5_ghz,
bssid: "8a:8a:20:88:7a:50",
channel: 116,
flags: [:ess],
frequency: 5580,
signal_dbm: -73,
signal_percent: 64,
ssid: "FlakyWiFi"
}}
]
This access point is currently set to WPA2 PSK. Do you see anything that might be different between my setup and yours?
from nerves_system_rpi4.
Below is my config, . I'm in Japan, the regulatory_domain is different from yours.
With this rpi4 can't grab the AP. So, VintageNet.get_by_prefix(["interface", "wlan0", "wifi", "current_ap"])
return [].
config :vintage_net,
regulatory_domain: "JP",
config: [
{"usb0", %{type: VintageNetDirect}},
{"eth0",
%{
type: VintageNetEthernet,
ipv4: %{method: :dhcp}
}},
{"wlan0",
%{
type: VintageNetWiFi,
vintage_net_wifi: %{
networks: [
%{
key_mgmt: :wpa_psk,
ssid: "ctc-a-a6f52c",
psk: "secret"
}
]
},
ipv4: %{method: :dhcp}
}}
]
I change regulatory_domain to US, then rpi4 grab the AP and return below.
iex(1)> VintageNet.get_by_prefix(["interface", "wlan0", "wifi", "current_ap"])
{["interface", "wlan0", "wifi", "current_ap"],
%VintageNetWiFi.AccessPoint{
band: :wifi_5_ghz,
bssid: "c0:25:a2:b1:4c:8f",
channel: 116,
flags: [:wpa2_psk_ccmp, :wps, :ess],
frequency: 5580,
signal_dbm: -61,
signal_percent: 85,
ssid: "ctc-a-a6f52c"
}}
Still, this connection is unstable, so rpi4 connect and disconnect repeatedly. Below is the log.

Just saw this commit that's timestamped yesterday:
* New clm_blob for BCM43456
- An updated clm_blob to open up the 80MHz channels.
* Use BCM43456 clm_blob on CYW43455
- The previous CYW43455 clm_blob provides limited access to the higher
5GHz channels (100+) - the BCM43456 (surprisingly) seems to work and
doesn't have this problem.
This would affect the RPi4 WiFi and sounds interesting.
