2012 Macbook Broadcom WL crashes during higher usage

Hi all, I am new here so apologies if I have made any mistakes in where to post.

I am running Arch x86 with kernel 6.13.4-arch1-1. I have installed the wl driver for my BCM4331 card to some success. Whenever I go to download a large program (or sometimes while streaming YouTube) the WiFi will suddenly cut out and cannot be restored. If I then try to turn the wifi off and back on again and reconnecting (Using KDE taskbar widget) it sometimes causes the whole system to crash, and then it will work perfectly on reboot.

The output of

lspci -vnn -d 14e4:

is:

02:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM4331 802.11a/b/g/n [14e4:4331] (rev 02)
        Subsystem: Apple Inc. AirPort Extreme [106b:00f5]
        Flags: bus master, fast devsel, latency 0, IRQ 17
        Memory at a0600000 (64-bit, non-prefetchable) [size=16K]
        Capabilities: <access denied>
        Kernel driver in use: wl
        Kernel modules: bcma, wl 

I know there may be something helpful in dmesg, but I don't know exactly what to narrow it down to using grep. Any assistance is welcome, I'd like to get this working to make it worth buying a new battery
I'd also like to do a fresh reinstall once I figure out what my issue is, but I am waiting since any major downloads require ethernet.
