Comparisons with other distros aren't meaningful as their software stacks are different and this is a software problem. If you can repeatably prove it works with earlier 10.0.x releases and then breaks at a specific release; this would be relevant.

Just wanted to make sure that it's not me and/or the hardware. I know that the software stacks are different. Step one: exclude the user in front of the device :D.

I can do more testing with different LE Versions if that helps but I will be on vacation from tomorrow until the end of the month, so it will take some time before I can get to it.

Did some more testing with the same Rpi4: swaped a few SD Cards with different systems on them to check if the 5 Ghz Issue is related to LibreElec or a general problem (hardware defect for example):

1. LibreElec (10.0.4 & 11.0.0) -> no connection possible ("invalid-key")

2. Raspian 64 Bit (Feb 2023 build) -> connection works just fine

3. PINN (3.8.4) -> connection works just fine

During all 3 tests the pi was in the same location / did not move so it can't be the signal strength either.

I am not 100% sure but I think the problems started with LE 10.0.3 or 10.0.4 and persist through LE 11.0.0.

I also noticed that Frequency=0 in my config files but didn't know the previous/correct value. Will give it a try as soon as possible and report back if it did the trick, thanks for the hint!

Edit: Nope, that parameter had no effect, still "invalid-key". This also happens immediatly. Like that nanosecond I click the connect button. No way that it actually tried to do stuff / handshake with the router or something I would say.

I have the same problem with LE 10.0.4: can't connect to my 5 Ghz WiFi getting "invalid-key" as response.

The entered password is 100% correct, also tried to edit it directly in the connman profile via ssh.

I have 2 different SSIDS, one for 2.4 and one for 5 Ghz. Both use WPA2 without PMF and the same Password.

Connections to the 2.4 Ghz SSID work just fine (same password!) but the speeds are very very low resulting in always buffering / stuttering playback. Trying to connect to the 5 Ghz SSIDs results in "invalid-key".

After finding this thread I updated to the LE 11.0.0 release, no difference / same problem. Any ideas?

You miss the fact that RPi4 does not support HDR > SDR tonemapping. There is no IP block on the chip to handle this translation in hardware and since 99.9999% of HDR media is 4K it's never going to be practical to handle this in software. Perhaps you have other devices which do have this capability?

I have multiple Kodi devices, indeed. They all share the same MariaDB.
One is a Windows Server driven HTPC-Server-Hybrid and the other is a very old acer switch convertible with horrible weak CPU (Windows 10) as well as two Rpi4 running LibreElec. I could swear that I had and used that feature a lot (none of my displays are HDR capable atm, i don't really care about HDR, my problem ist that HDR material looks meh on SDR displays without tonemapping ) on the Pis with 10.0.1. because they are my main devices in the living- and bedroom.

But now that you say that it is practically not possible because of hardware limitations I might have used my Notebook for that and don't remember it... Hmmm getting old, heh?

Hello there,

maybe i missed something and this turns out to be a pretty stupid question but I am pretty sure I double checked my Rpi4 with Libreelec 10.0.2:

has the HDR tonemapping support (HDR Source -> SDR Display) been dropped/removed in 10.0.2 compared to 10.0.1?

I am 99,99% sure that I had an additional option in the video settings while playing HDR sources to enable a tonemapping (choose from multiple algorithms) to port it down to SDR that worked very well.

But after updating to 10.0.2 it seems I am missing that option.

What did I miss?
