Brodcom-sta-dkms driver with elementaryOS-8.1 on a MacBookAir (intel)

### What Happened?

Hi all,
I'm new on this forum.
I recently installed Elementary OS 8.1 (using elementaryos-8.1-stable-amd64-20260219.iso) on a old MacBook Air. Once installed, the Wifi connection seems to be not good (disconnects frequently) and the system asks to install the driver "broadcom-sta-dkms" but the installation of the driver fails.
Error while installing package: "installed linux-headers-6.17.0-23-generic package post installation script subprocess returned error exit status 11".
In the same time the command "uname -r" returns "6.17.0.14-generic"
Installation of ElementaryOS 7.1 works well (module b43 installed), except that the updating fails, may be the same problem ?
Any help ?

### Steps to Reproduce

1. Install ElementaryOS 8.1 on MacBookAir
2. WIFi connection does not work
3. Install ElementaryOS 7.1
4. Wifi works
5. Upgrading does not work
