Can't get 5Ghz AP to work (Raspberry Pi 3+ and Pi4)

  • I want to use the Tethering/Access Point feature on my Raspbarry Pi, and I want to use the 5 Ghz frequency. I've installed Network tools, but no matter what I try, as soon as I select "Enable 'tethered' Wireless Access Point' things appear to drop back to 2.4 Ghz. I'm assuming that the feature needs updating so that Libreelec offers 2.4 and 5 Ghz AP availibility? Is there anything I can do to force 5 Ghz? BTW - connecting the Pi as a 5 Ghz client works fine.

  • I have a feeling that connman AP mode was made as simple as possible and be available for most devices i.e 2.4MHz.


    As a test, can you turn off 2.4GHz on your router and see if tethering still works on 5GHz.

  • Don't understand what you are trying to tell me. I have a Pi4 with libreelec. I use the Ethernet connection for most things, so I'd like to use the Wifi as an Access point. It works fine at 2.4 Ghz, but 5.0 Ghz doesn't.

    As I wrote in my previous post I can connect my Pi4 to my Netgear 5 Ghz router.

  • The hotspot (not access point, hotspot) feature comes from software called "connman" that manages connections in the OS. It was originally written for a mobile phone OS to provide a tethered hotspot, e.g. laptop connects to mobile and shares the mobile connection. As a result it is deliberately simple and the only configuration options are on, off, and the ability to change SSID and passphrase. If you want an access point with access point features and config options, you need to get an access point.

  • Thanks for your reply "chewitt"!!


    I think people need to re-read my original post. Maybe I'm actually asking for an additional feature, but I believe a feature that will improve the product, libreELEC, which is an excellent product.


    Let's keep things simple: Libreelec has a feature under "Setting/LibreELEC/Network/Wireless Networks (Active)" called "Enable 'tethered' Wireless Access Point". If I enable and set things up, I can connect with my remote device's WiFi (so, my mobile phone in this case) and connect to the Internet over the 2.4Ghz frequency. Great! The feature works :-) Now the part which really concerns my question. I have got LibreELEC, running on a PI 3B+ and a Pi4 which can handle the 5Ghz frequency, but I cannot connect on the 5Ghz channels/frequencies. It would be great to connect using my 802.11ac capable devices, so 5Ghz, so I can have far faster Device <-> Pi/LibreELEC <-> Internet speeds.


    My guess is LibreELEC cannot support 5Ghz/802.11ac yet??? No problem if it is not supported, but maybe someone the development team would be interested in implementing?

  • The current connman feature is working as designed. It just wasn't designed to do much (2.4GHz) because that's fast enough for data sharing between a phone and a laptop. Enhancement to add support for 5GHz and more config is not impossible, but it's not a simple task and we don't have people on-staff with the skillsets to do it. So your choices are: a) find someone with the skills and willingness to code it, or b) get a proper access point.
