Can't connect 5GHz WiFi when using 1.13.1 #70
Comments
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 |
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"])
[

] This access point is currently set to WPA2 PSK. Do you see anything that might be different between my setup and yours? |
Below is my config, . I'm in Japan, the regulatory_domain is different from yours.
I change regulatory_domain to US, then rpi4 grab the AP and return below.
Still, this connection is unstable, so rpi4 connect and disconnect repeatedly. Below is the log.

I think that the firmware is out of date. Due to a missing firmware file and looking out-of-date, I switched wifi firmware repositories in this release to the |
Just saw this commit that's timestamped yesterday:
This would affect the RPi4 WiFi and sounds interesting. |
@fhunleth I tried the fw and I confirm it works with 5GHz WiFi AP which is I mentioned earlier. |
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! |
Environment

Current behavior
Connecting 5GHz WiFi is failed, cause of below error, when we use nerves_system_rpi4 1.13.1.
This doesn't happen on nerves_system_rpi4 1.13.0.
I asked my friends to reproduce this, then it also happened with friend's WiFI 5GHz AP.
Expected behavior
This phenomenon may be due to rpi4 drivers rather than "Nerves", but user should know.
Please let me know if there is any other information you need. Thanks.
