Razzy,
I’m back to square one on this. I’m seeing the same results as I originally did when I first got my KLC.
iwconfig
iwlist wlan0 freq
The problem then is that I didn’t actually solve the issue. It more or less fixed itself! (Kobo Libra Colour can't see 5GHz networks
https://www.mobileread.com/forums/sh...d.php?t=360958).
Just like you, it only seems to support 2.4 GHz channels through the dropdown list, even though it’s currently connected to a 5 GHz channel. So the KLC can connect to mixed frequency channels at 5GHz, but it can’t even see dedicated 5GHz channels?
But now I’m irritated, so I’ll be picking away at this issue till I fix it. Anything you discover, please share here.
Is there anything like “nmcli dev wifi” on Linux Kobo? That would show the list of available WiFi channels. Might be instructive to compare with the results above.
