Intel AC 9560 wifi slow speeds

Hi all,

I have FreeBSD 15.0-release-p6 running on a HP Spectre laptop. I am pretty happy with this setup, Plasma 6.6.4 on wayland, and all my jails running nicely.

The laptop has the following network data from pciconf

iwm0@pci0:0:20:3: class=0x028000 rev=0x30 hdr=0x00 vendor=0x8086 device=0x9df0 subvendor=0x8086 subdevice=0x0034
vendor = 'Intel Corporation'
device = 'Cannon Point-LP CNVi [Wireless-AC]'
class = network

and the output from dmesg:

iwm0: <Intel(R) Dual Band Wireless AC 9560> mem 0x404a11c000-0x404a11ffff irq 16 at device 20.3 on pci0
iwm9000fw: could not load firmware image, error 8
iwm0: hw rev 0x310, fw ver 34.3125811985.0, address 50:76:af:22:da:17


Even though I see the firmware error message, the network itself is working as seen from ifconfig

wlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500

My issue is, even though everything seems to be in order, and ifconfig reports being in 11g mode,
my best wifi speed does not seem to go beyond 22Mbps, even though all indicators are I should be able to get the full 54Mbps possible.

kldstat output shows:

...
12 1 0xffffffff83a11000 c74a0 if_iwlwifi.ko
13 1 0xffffffff837bf000 17314 if_iwm.ko
...

My home internet is a speedy 900Mbps connection and all my other wifi devices are rather snappy.
Any help would be appreciated to check if I could attain higher speeds, atleast 11g, if not 11ac


EDIT: fwget reports the following:

Needed firmware packages: 'gpu-firmware-intel-kmod-kabylake wifi-firmware-iwlwifi-kmod-9000'
The most recent versions of packages are already installed.
