No wifi in patched ubuntu

[moshin34]

This is on 2018 MacBook Air A1932 MacbookAir 8,2.

Ubuntu looks beautiful and snappier than ever!! But no WIFI! :-(

What I did:

1. Clean install of Mac OS, Upgraded to latest
2. Ran the firmware.sh in MacOS
3. Installed the patched ubuntu 23.10 iso
4. Ran the firmware.sh in linux

When that finished, I then run sudo journalctl -k --grep=brcmfmac to confirm but

I get

before the lines that say direct firmware load failed with code -2, it says:

brcmf_fw_alloc_request: using brcm/brcmfmac43551c1-pcie for chip BMC4355/12. (in red)

and after the direct firmware load failed with code: -2's

brcmf_pcie_setup: Dongle setup failed (in red)

When I manually run the commands I go to /tmp/apple-wifi-efi and firmware.sh isnt there.

When I copy it there, or run from anywhere It just echoes

Detected Linux Re-mounting the EFI Partition Getting Wi-Fi and Bluetooth Firmware

I noticed there is a folder in /tmp/apple-wifi-fw but it seems empty.

Also, I have a weird thing perhaps. I have a wired connection that shows up in the top right and in settings. Where it tries to connect at 100Mb before eventually failing.

dont laugh,

echo "1" | sudo tee /sys/bus/pci/devices/0000:01:00.0/remove

after this, i lose my keyboard and mouse. Screen freezes. I try to use the ; between commands but then i get input out put errors.

Rescan alone, doesnt seem to do much of anything.

sleep 1 echo "1" | sudo tee /sys/bus/pci/rescan

[AdityaGarg8]

sudo modprobe -r brcmfmac_wcc
sudo modprobe -r brcmfmac
sleep 5
sudo modprobe brcmfmac
sudo systemctl restart NetworkManager

Try this

[moshin34]

sudo modprobe -r brcmfmac_wcc
sudo modprobe -r brcmfmac
sleep 5
sudo modprobe brcmfmac
sudo systemctl restart NetworkManager

Thank you.

I entered all the above as instructed, but nothing seems to have changed. I didn't reboot, which I will now. But I suspect that will be moot.

Perhaps interestingly, but likely irrelevant. I was able to connect it to a TB/USBc Dock and the ethernet was recognized from the dock.

[AdityaGarg8]

Well since it's an upstream driver, I'd suggest mailing your issue to the Linux kernel maintainers.

If interested, I'll send the email addresses to you.

[moshin34]

Ok, yes please. I guess Im just screwed on this model for now? I should email them and try different hardware?

Thanks!

can you send all the brcmfmac messages between these two:

brcmf_fw_alloc_request: using brcm/brcmfmac43551c1-pcie for chip BMC4355/12. (in red)

brcmf_pcie_setup: Dongle setup failed (in red)

looking at that, it seems like it can't find the firmware files. maybe check if there's anything in ls /usr/lib/firmware/brcm | grep apple.
