[SOLVED] Cannot connect to wifi (Macbook Pro 14,2)

YesImHuman · 2024-01-14 17:22:45

Hi, i've recently installed Arch Linux on my old macbook from 2017, a Macbook Pro 14,2 but ive had a lot of trouble to get the wifi working correctly, i did get it working on my home wifi for maybe 2 or 3 days but after that it already broke, didnt get it to work at work or at my moms place, but i know that the wifi card works.

Ive tried it with NetworkManager, iwd and wpa_supplicant (not at the same time ofcourse) and nothing has been working.
Only way i've even been able to get it to work with ethernet is when NetworkManager is enabled.

All i know is that when i try it with NetworkManager i get

association took too long

from the journalctl and nothing else
When i try it with wpa_supplicant i keep getting

CTRL-EVENT-ASSOC-REJECT bssid=00:00:00:00:00:00 status_code=16

and then it stopping because conn failed
And when using iwd i get

CMD_SET_CQM failed: Operation not supported

in the journalctl and nothing else again

I'm kind of at a loss, i have the driver installed correctly, the ip link device is on, nothing is blocked when looking at rfkill

Heres some extra info i could get using iwconfig

iwconfig
wlp2s0  IEEE 802.11 ESSID:off/any
        Mode:Managed Access Point: Not-Associated Tx-Power=31 dBm
        Retry short limit:7 RTS th:off Fragment thr:off
        Power Management:on

And its a `BCM43602 (14e4:43ba)` wifi card thats in the macbook

Sorry if i havent provided enough information, its a bit hard to copy it all without wifi.

Yeah, common issue w/ macbooks because it's the worst wifi chip family to have: https://wiki.archlinux.org/title/Broadcom

lspci -k

In doubt try https://wiki.archlinux.org/title/Broadc … roadcom-wl and post your complete system journal for a boot after trying to use the wifi:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

YesImHuman · 2024-01-14 18:24:23

`lspci -vnn -d 14e4:`
https://0x0.st/HUI3.txt

and this is after following 3.3.2 from that link and trying to connect using NetworkManager after that

not sure why but saw iwd still in the journal, disabled it, rebooted and now i dont have an interface anymore except the localhost one

Head_on_a_Stick · 2024-01-14 19:20:47

You should probably share the new journal contents from a (single) boot with the missing interface.

YesImHuman · 2024-01-14 19:31:56

heres the new journalctl, worked it out with some friends why the interface wasnt showing up, was after installing the broadcom-wl and modprobing it
needed to modprobe brcmfmac again, but still at step 1 again, only NetworkManager and it just gives `association took too long` again

YesImHuman · 2024-01-14 20:10:26

also got this from dmesg https://0x0.st/HUlu.txt

V1del · 2024-01-14 20:52:56

you are mixing iwd and networkmanager in an incompatible way. On a broadcom chip I'd suggest you stick to NetworkManager (wpa-supplicant) so you should disable iwd.

broadcom-wl seemingly fails (you can remove that again) and for brcmfmac

pacman -Qs firmware

ill try uninstalling iwd and broadcom-wl and running that pacman command and reboot in a bit

You don't seem to scan for any AP but connect to the SSID 'Notive Office'
The connection attempt simply times out, you're actually getting rejected (the response is from the 00:00:00:00:00:00 BSSID)

1. Can you actually scan for APs?
2. Disable https://wiki.archlinux.org/title/Networ … domization
3. You ddin't comment on the nature of the desired AP wrt. https://wiki.archlinux.org/title/Broadc … a)_devices

YesImHuman · 2024-01-15 14:54:03

i just use nmtui but it automatically shows the detected wifi points. about the mac randomization, ive had that config set for quite a bit already since thats one of the first things i found online.
and about the 5G, ive tried switching but i believe it was iwconfig that only shows that frequencies between 2400 and 2600 are supported, something like that, but even then, i didnt manage to change anything including the channel, not sure if i mightve tried it incorrectly though.

I'll try to go through the iwconfig again once i have time and try and change the channel again

seth · 2024-01-15 15:25:20

ive had that config set for quite a bit already since thats one of the first things i found online

And it is what time and time again APs hate. Disable it.

Also stop NM and manually scan for APs.

Wrt. the channels, you'd inspect and change them in the AP, not the notebook and for a dual-channel AP (2.4 and 5GHz on the same SSID) you could try to connect to the 2.4GHz BSSID (MAC address) explcitily.

YesImHuman · 2024-01-16 08:07:50

just so i understand correctly, disable nm, and connect using wpa_supplicant manually by using the mac address?

also, sorry, but im not too familiar with the terminology, what does Wrt stand for?

seth · 2024-01-16 08:51:16

"with regards to" and yes, the plan is to stop NM, then manually scan for the AP, then manually try to connect to it.

Edit: if you want, you can also first test wifi-menu from netctl, it's more convenient.

Ive googled a bit more and found the solution, i still dont understand why it would work but atleast it works now.

sudo iwconfig wlp2s0 txpower 10dBm

thats all i needed to do

That raises or lowers the transmission power.

Jan 15 12:50:17 arch kernel: brcmfmac: brcmf_c_process_clm_blob: no clm_blob available (err=-2), device may have limited channels available
Jan 15 12:50:17 arch kernel: brcmfmac: brcmf_c_process_txcap_blob: no txcap_blob available (err=-2)

might be related.

Do you have the link suggesting the fix?
You probably want to record that at https://wiki.archlinux.org/title/Laptop/Apple

YesImHuman · 2024-01-17 20:14:39

here is where i got the answer from, searched for the chip instead of the laptop which finally gave it

https://askubuntu.com/a/1092280

seth · 2024-01-17 20:21:51

=> https://bugzilla.kernel.org/show_bug.cgi?id=193121#c26

What Tx-power does

iwconfig wlp2s0

show before? Do you also get away w/ 20dBm ?

YesImHuman · 2024-01-22 07:38:52

ill try in a bit to see how high i can get with it

YesImHuman · 2024-01-25 08:00:44

update: i tested it out, 20dBm seems to be fine, 25dBm seems to get a bit on the unstable side where it starts to take longer to connect to the router
