[Bug 288186] RTW880 wireless not working during installation

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=288186

            Bug ID: 288186
           Summary: RTW880 wireless not working during installation
           Product: Base System
           Version: 14.3-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: wireless
          Assignee: wireless@FreeBSD.org
          Reporter: vishalpaudel@outlook.com

I am trying to try out BSD after using and finally being bored of Linux for 3
years. So I would appreciate your help in getting me to the other side.

During FreeBSD installation on my HP Laptop without ethernet and with 4GB of
RAM, I have encountered a WIFI issue.

`pciconf -l | grep rtw`

outputs:

`rtw880@pci0:1:0:0:        class=0x028000 rev=0x00 vendor=0x10ec device=0x822
subvendor=0x103c subdevice=0x85f7`

I have followed Bug 272145 so far. There are a couple of old bug reports about
this, but I rather wanted to start a new thread about it.

The issue occurs after the available networks are listed and I fill the
password.

I tried this with
`FreeBSD-15.0-CURRENT-amd64-20250710-78935fa40eee-278643-memstick.img`, but the
installer I think crashes and goes to the debugger prompt after I enter the
prompt.

However for `FreeBSD14.3-RELEASE-amd64-memstick.img`, after filling in the
password, the following errors start filling the installer screen
intermittently just as given below:

```
rtw880: failed to send h2c command
rtw880: failed to poll iqk status bit
rtw880: failed to do dpk calibration
rtw880: failed to do dpk calibration
rtw880: [TXGAPK] unknown channel 234!!
```

During the installation I tried hopping to a shell and editing the
`/boot/loader.conf` on vi to add `compat.linuxkpi.skb.mem_limit=1`, but I could
not edit "read only filesystem".

I will try the last approach from within the installation maybe that will work
around the filesystem mutability, but I don't think that is the problem as I
already wrote, I have 4GB of RAM. How should I get going from here?

Your guidance would help me make the leap from Linux to BSD, thanks.
