Intel(R) Wi-Fi 6 AX201 160MHz low link speed (slow speed - uses MIMO 1x1 @80Mhz only it seems)

I have a PC with an ASUS Rogstrix Z690 Gaming WIFI-D4 motherboard which comes with an Intel Ax201 160MHz wireless module.

Since I've upgraded my internet subscription to a 1Gbs fiber connection, I noticed my PC, links poorly to my router and therefore I get an extremely poor connection speed despite having a 1Gbps fiber connection.

Like instead of getting 866.6Mbs (because router is WiFi5 (supports 802.11ac) it only gets anything from 26 Mbs to at most 433.3 Mbs! and rarely (only once in the past 4 weeks, 650Mbs which quickly went down to 290Mbs!) and even that is not stable and fluctuates constantly!

My phone which uses a cheap WiFi-5 wcn3990 chip, can link 866.6Mhz 30 feet away, but my PC can't even link no where near that number literally adjacent to the router!(and I mean literally literally!)

Here is my PC in my room 24 feet away (router is in the other room)(today - the PC power setting is set at Performance):

(base) hossein@hossein-pc:~$ iwconfiglo        no wireless extensions.enp5s0    no wireless extensions.wlo1      IEEE 802.11  ESSID:"Unknown-F5"            Mode:Managed  Frequency:5.745 GHz  Access Point: F0:2F:A7:F0:CA:69             Bit Rate=351 Mb/s   Tx-Power=22 dBm             Retry short limit:7   RTS thr:off   Fragment thr:off          Power Management:off          Link Quality=60/70  Signal level=-50 dBm            Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0          Tx excessive retries:0  Invalid misc:11   Missed beacon:0virbr0    no wireless extensions.docker0   no wireless extensions.

When the PC is in balanced mode (this is a few days ago):

-pc:~$ iwconfiglo no wireless extensions.enp5s0 no wireless extensions.wlo1 IEEE 802.11 ESSID:"Unknown-F5"Mode:Managed Frequency:5.745 GHz Access Point: F0:2F:A7:F0:CA:69Bit Rate=260 Mb/s Tx-Power=22 dBmRetry short limit:7 RTS thr:off Fragment thr:offPower Management:onLink Quality=54/70 Signal level=-56 dBmRx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0Tx excessive retries:0 Invalid misc:6 Missed beacon:0virbr0 no wireless extensions.docker0 no wireless extensions.

Taking the PC to the other room and placing it next to the router doesn't change anything despite having a prefect link quality(70/70), signal level (-25 db), it got me a bit-rate of 433.33MHz! only.

-pc:~$ iwconfiglo no wireless extensions.enp5s0 no wireless extensions.wlo1 IEEE 802.11 ESSID:"Unknown-F5"Mode:Managed Frequency:5.745 GHz Access Point: F0:2F:A7:F0:CA:69Bit Rate=433.33 Mb/s Tx-Power=22 dBmRetry short limit:7 RTS thr:off Fragment thr:offPower Management:onLink Quality=70/70 Signal level=-25 dBmRx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0Tx excessive retries:0 Invalid misc:6 Missed beacon:0virbr0 no wireless extensions.docker0 no wireless extensions.

It seems its only working at 1x1 MIMO! instead of 2x2 MIMO at 80Mhz channel! (with MCS Modulation 256 QAM and encoding 5/6)

My Router is a 4x4 MIMO Hawei EG8245W5 GPON Terminal and I believe my motherboards WiFi chip, Intel AX201 160MHz, to also be a 2x2 MIMO module. so it should be able to properly link and achieve a decent and stable connection but it doesn't.

Side-note:

I have seen a lot of posts about this specific module on Ubuntu, but none of them really helped, as many were for previous versions of Ubuntu dating a few years back, so I decided to ask a new question. I gathered the information some of those previous questions had posted, and tried some of the ways they were told to try and wrote their results below.

Please kindly tell me if I posted this in the wrong section, since there were already similar questions, I decided to post it here (I was skeptical to whether post this on superuser site or here)

• I tried booting a 24.04.1 live cd to see if the new version fixes this or not, it doesn't! could it be because we are using the same kernel version? (I'm using 6.8 and I believe 24.04.1 is also on 6.8)

• I also tried sudo apt install firmware-iwlwifi to no avail, that package doesn't exist in 22.04 it seems.

• I also tried sudo apt install linux-generic-hwe-22.04 nothing changed.

• I also disabled the power save by setting:wifi.powersave = 2 in /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf and also set the ubuntu to Performance mode (from settings dropdown menu) but nothing changed.

• I also tried updating the firmware, but it seems nothing changed for some reason, either I did something wrong, or I failed to do more needed stps.
  What I did was to :

git clone https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/cd linux-firmware/sudo cp iwlwifi-*.ucode /lib/firmwaresudo update-initramfs -usudo reboot

but nothing changed after reboot (I noticed the drivers werent updated as the output of sudo lshw -C network showed the firmware was still the same!)
