[RG35XX Plus] Wifi not working

[steilerDev]

Knulli build version

40-dev-d8b86623f3 2024/05/30 01:50

Your architecture

RG35XX Plus

Issue description

When trying to find nearby Access Points, the "Scanning..." modal only briefly appears and no APs can be found.

Manually inserting SSID and PSK did not work either.

Detailed reproduction steps

1. Fresh install
2. Go to Network Settings
3. Search for nearby AP
4. No AP shows up - manual connection to SSID is not working either

Details of any attempts to fix this yourself

• Disabled WPA3 on AP
• Disabled 5GHz on AP
• Tried different AP

Details of any modifications you have made to Knulli.

Fresh install.

Logs and data

Since I had no success accessing the terminal locally on the device, I was only able to run very simple scripts to get data off the device. Attached is dmesg output, but let me know what else would be useful.

I'm having the same issue here on my new RG35XX Plus, I've been doing all kind of stuff as this is my first time with the device

[steilerDev]

I was able to establish shell access to the device (through an ethernet to USB-C adapter).

A couple of findings:

• No wifi interface shows up in ip a:

• batocera-scanlist returns immediately and empty
• iw dev returns empty
• I can see that there is a wlan module available in /sys/firmware/devicetree/base/soc@03000000/wlan

Not sure where to go from here - let me know how I can debug this further

Edit: cat /sys/firmware/devicetree/base/model gives me sun50iw9 - not sure if this is maybe different to other RG85XX+?

Try to run lsmod to see if the wireless drivers are being loaded. You can also run dmesg and upload the output here.

btw - I noticed Bluetooth does not seem to work either (from /var/log/bluetooth-agent.log:

Thanks for looking into this!

Disabling 802.11w Management Frame Protection works for me.

This is my OpenWrt AP configuration:

[steilerDev]

All of this is already disabled :/

[jajadannn]

Having the same problem here, has someone found something?

[jajadannn]

I found that when I make an Hotspot over my PC with the 2.4Ghz Band it works just fine.
In 5Ghz mode it works too. Could someone try to use an Router without an Mesh connection?

[steilerDev]

I'm 99% confident that the issue I am facing is on the Anbernic and not my network - there are a few networks around me, including very badly secured 2.4ghz ones from my neighbours, the device is not able to see any of them (I'm not even trying to connect to them)

[jajadannn]

I know, but why does it work with WPA3 and 5Ghz on my PC Hotspot and not on my local Network

[steilerDev]

Maybe @diegombeltran's input could help you @jajadannn - but I think your issue is distinct from mine and should be handled in a separate issue.

[Dreadlocke12]

Have the same issue. Connecting to hotspot works but not when connecting to my home wifi unless i remove the wpa2 authentication and have an unprotected wifi.

[Dreadlocke12]

I tested a few custom os and this seems to be the same issue in the previous battocera build i think it was 40 as well and on the stock os. In Muos i can connect to the same wifi though if that helps.

[IM0001GT]

Need to bump this as I'm a little puzzled as well. Have both an 35XXH and Plus and both cannot seem to connect to my Ubiquiti WPA2/3 network. Even when I drop the network down to just WPA2 it doesn't want to connect. Doing the same to my Pixel 9's WPA3 hotspot works fine though as others have had similar luck.

Going to do a few more test and see if I can narrow it down to any one setting on the network but as it's a WiFi 7 network, this is going to grow into a larger issue over time as networks evolve.

[Dreadlocke12]

I have as well a Ubiquiti Access Point and for me it works without using any password with MAC Adress authentication. Not the best solution but better than no connection.

[IM0001GT]

I have as well a Ubiquiti Access Point and for me it works without using any password with MAC Adress authentication. Not the best solution but better than no connection.

This is pretty much the only way I can seem to get it to work as well. Created a new WiFi network and even with all the optimizations or other settings disabled, the RG35XX*'s will not connect to the network if it has any security on it. They also seem to have issues connecting if the network is Hidden. Only having it Open and enabling MAC Address Filtering seems to be a way to secure the network while allowing them to connect.

The weird thing too is the H seems to be a little different than the Plus in how it's WiFi works. The Plus was being a real sticker trying to get it to connect AND pull an IP, while the H just hopped on and worked just fine. After some tinkering and setting a static IP from my Ubiquity Gateway, the Plus finally decided to play nice after like an hour of fiddling.

Overall, I would like to dig more into this to possibly see why this is happening and why it's having so much trouble. Heck I'd like to see the MAC address and set an IP manually from in the OS as well but that can come whenever.

The only other device in my house having any issues with this network is an old Surface Pro 3 with the old Marval AVASTAR AC adapter that had issues with the old drivers, but a new 2021 driver fixed that right up.

[lanmarc77]

I have the same issue. No wireless connection. After logging in the same sneaky way like @steilerDev I could also see that there is no wireless interface. If there is no interface then I do not see how changing wireless hotspot settings would help.
I am using the version firefly.
As others seem to be able to connect I can only assume that there could be different hardware revisions. I attach a picture of the back sticker of my model.

EDIT:
I think this is a marketing mess up. The packaging box says RG35XX 2024. This model does not have wireless modules. @steilerDev if you have the same sticker and box packaging this might apply to your model as well.
