No Wifi While and After install ArchLinux

#1

I use

iwctl
device list

No device show, but actually, the several wifi available.
And though I use wifi via USB share by mobile phone. I can’t access it via SSH.
All the response is

ssh: connect to host 192.168.171.1xx port 22: Connection timed out

All the devices are under the same local net.
The output of dmesg

brcmfmac: F1 signature read @0x18000000=0x156264345

After search I found no files about brcmfmac43455-sdio.txt and brcmfmac43455-sdio.Radxa-ROCK Pi X.txt

#2

I added some files from some users, now the wifi is working, but it can only connect to my mobilephone hotpoint but can’t connect to other wifi

nmcli device wifi connect my_wifi_name password my_wifi_password
Error Connection activation failed: (7) secrets were required but not provided
#3

Now the error is solved. The wifi signal is too weak.
Now I update the AP6255 patch to AUR. Everyone can easily make wifi works after installing Archlinux via command

yay -S rockpix-ap6255
