Internal Wifi doesn't work

[Thranthir]

I am using my Powkiddy RGB10 Max with the recent RetroOZ Version (0.51)

Unfortunately, the internal Wifi is not working. I can choose my Network and add the Password, but it does not activate.

I already tried the Hotkeys and the WiFi-Switch is ON.

Am I the only one? Is there any solution?

Wifi with EmuELEC is working fine on the same device.

Sounds like a missing kernel module, what is the chipset?

Hey,

thanks for the response.

According to a Forum Post, I found, it should be the RTL8723
do you know how I can get this info to verify without disassembling the Device?

Regards

It works just fine on my RGB10 Max.

That is wierd, mine also works fine, I will check the chipset to see if there is a match.

To check, connect an ethernet adapter, ssh and enter dmesg copy the output and paste it here as an attachment.

Unfortunately, i dont have a Ethernet-Adapter, but i could use the Terminal of EmuELEC to generate a dmesg.

When i recognize it correctly, it is the rtl8723bu chipset

Unfortunately, as the chipset and serial number match and my RGB10Max functions without a problem there is not much more I can add, feel free to compile your own kernel using my Github versions https://github.com/southoz/linux and modify the drivers. I would double-check that you have not disabled the wifi with the hotkey combination https://github.com/southoz/RetroOZ/wiki/Hotkeys

Hey, i now have a Ethernet-Adapter and could extract the dmesg of the actual device with RetroOZ.
The output is attached. The Driver initialization failed.

If you need some logs or more information, it may delay in my answer, I will be on vacation for the next two weeks.

Initiates and does not connect also attempt to start Bluetooth which is not supported, try a fresh flash on a spare SDCard

I am having the same exact issue with internal wifi not working, networks show up on the list. Input the password, "please wait" flashes on the screen for half a second and then no connection.

Hey, I reinstalled the OS freshly. I found an interesting behavior. When I use a Hotspot with my phone, it works, but with the "home" WLAN (I use an AVM FritzBox Router) it still doesn't work.
