Hi all, I can confirm that this problem also occurs for me at an older
802.11ac upgraded iMac6,1 and iMac8,1 computer. This is the case for
kernel 6.11.0-17 as well as kernel 6.8.0-54. The used WiFi card is an
Apple Broadcom BCM94360CSAX.
This problem is present since the upgrade to Kubuntu 24.04 LTS. On
Kubuntu 22.04 LTS and older 5.x based kernels the WiFi card worked
mostly without any problems.
However, it looks that this doesn't occur on every 802.11ac upgraded
iMac. At least for an iMac5,1 computer the BCM94360CSAX card seems to
work fine under Lubuntu 24.04 LTS and newer 6.8 and 6.11 kernels.
