9.2.0 RP4 Drops Wi-Fi after 1 min

1st Official Post

    Hi guys,

    clean install, no addons. RP4 connects, works for 1min, then connection drops and RP4 is not able to reconnect. Looks like this happens after scan is complete.

    The log

    Router - ZyXEL Keenetic Ultra II, no 2.4, only 5GHz, log says:

    Any ideas? Thanks in advance.

    P. S. With Raspbian Buster, Wi-Fi works with no problems.

    I remember that other RPi 4B users have the same problem with 5GHz WiFi. Because it works with the same Hardware (same RPi, same PSU) on Raspbian Buster, I assume it's a bug on LE. My guess about the bug is that LE uses a different energy management. 5GHz needs more energy than 2.4GHz. Maybe write a bug report to give the bug more attention. I think that's all you can do.
