[2508.4][RG40XX-H] WIFI disconnects after 20sec

[dunecrawler]

A few days ago I bought a new Anbernic RG40XX-H with a new SD-card and flashed it with the latest muOS (Loose Goose 2508.4). All works fine, except the WIFI: It keeps disconnecting after 20..25 seconds.

I tried both 2.4 and 5GHz bands, but it does the same on both. I have my WIFI access-point configured with 802.11n, using WPA2-PSK with AES encryption. Other devices on the network (multiple brand laptops, phones and IOT devices) are all good with these settings, but the RG40XX is not.

I played with all network setting combinations but it keeps disconnecting shortly after it obtained its IP address and other DHCP settings.

When looking in the Network Details screen, it will show valid values for hostname, MAC address, IP address, SSID, gateway and DNS servers, but the signal and channel will drop to “Not Connected“ shortly after I manually reconnect from the WiFI Network screen.

Any ideas how to debug? Tips what (legacy) settings I could use on my WIFI access point instead?

I just noticed a lot of entries in the log of my access point saying: “client [mac of device] failed to connect to [mac of AP] with SSD [ssd-name]“ on channel [chan nr] because WPA authentication failed ([n] times in a minute).”

However, each time it does connect for a little while (less than half a minute) I can ping it or even login to it using SSH before the connection drops again. So these log entries don’t make sense to me - I would expect it can’t connect at all if authentication fails.

Are there any network logs available in muOS, or can that be enabled in some way?

Anbernic devices seems to have a lot of problems lately when it comes to hybrid WPA2/WPA3 mixed mode type of connection. It does not do well at all with WPA3

Of course, I would never recommend lowering security for any device ever, but did you try enabling wpa2 only see if it helps?

It does not do well at all with WPA3

My network setup consists primarily WPA3 with separate 2.4Ghz and 5Ghz channels. All currently supported devices work just fine.

The issues stems from APs doing “smart” channel switching. So as long as you have differing SSIDs with channels it will work just fine with either WPA2 or WPA3.
