This bug was fixed in the package linux-firmware-raspi - 13-0ubuntu1

---------------
linux-firmware-raspi (13-0ubuntu1) questing; urgency=medium

  * New upstream boot firmware
    - Fix booting with un-ordered MBR table and tryboot_a_b (LP: #2121612)
    - H.264 codec generates garbage at 1920x1200
    - Support HAT+
    - Support HAT EEPROM dtparams
    - Populate number of numa nodes based on sdram configuration
    - Avoid increasing arm frequency when throttling
    - imx500: selectively increase i2c_vc_baudrate based on FW version
    - Add support for software uart using the second VPU core
    - Add memory barrier to the mbox handler
    - GPT autoboot/reboot partition number fixes for Pi4 and older
    - Add support for [partition=N] config.txt on Pi 4
    - Add support for the current_supply HAT+ property
    - Don't look for boot-partition inside hybrid-GPT partitions
    - Rev 1.4 3B+ also needs the NO_BT_ON trait
    - Correct some mailbox response lengths
    - GET_CLOCKS: Set useful response length
    - Enable "Starting ARM" log message
    - Allow more tolerance for incorrectly programmed otp
    - Add config option to enable the watchdog timer from the firmware
    - Also require the early-watchdog property
    - Use the Ethernet PHY address probed by the bootloader
    - Fix boot-watchdog stop on Pi4
    - Fix config key search which could cause camera_autodetect to fail
    - Add boot.img ramdisk support for Pi3 and earlier devices
  * New upstream wifi firmware, 1:20241210-1+rpt2
    - Fixed operation of brmcfmac43455 chips on questing's kernel
      (LP: #2121560)

Title:
  Wifi failing to work on questing daily

Status in linux-firmware-raspi package in Ubuntu:
  Fix Released
Status in linux-raspi package in Ubuntu:
  Invalid
Status in wpasupplicant package in Ubuntu:
  Invalid

Bug description:
  On the current questing dailies, Wifi is failing to operate on all Pi
  boards with a 43455 (or similar) chip. Specifically, this is affecting
  the 3+, 4B, and 5 (and variants thereof including compute modules).
  The symptom appears to be that authentication is timing out, followed
  by a pile of set chanspec warnings (but that's probably just LP:
  #2063365 still rearing its head).

  I'm not sure if this is a firmware, kernel, or wpa_supplicant issue so
  I'm going to mark this as affecting all three for now, and sort out
  which is at fault later.
