Unrealistic Tx-Power for wifi interface

I recently built a desktop computer with the following parts:

  • AMD Ryzen 5 5600X CPU
  • ASRock AM4/X570M Pro4 mother board
  • Intel AX210 wifi/bluetooth card. It’s mounted on a M2 slot

I’m on Archlinux. Everything works well but the network card. The card is recognized, but neither the wifi nor the bluetooth work.

When I run iwconfig on the wifi interface, I get a weird value:

❯ iwconfig wlp4s0
wlp4s0    IEEE 802.11  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   Tx-Power=-2147483648 dBm   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Power Management:off

I’ve been trying various kernels/firmwares with no change all day and I’m starting to think the card faulty.
Is it normal to have this kind of value for tx-Power?
