Broadcom WiFi cannot connect

Peam269 · 2023-08-23 03:05:13

Hey everyone,
I've got a BCM94360 (BCM4360 with PCI-ID 14e4:43a0) and installed the broadcom-wl-dkms driver after linux-headers.
Now, after rebooting, I can scan for networks but not connect to them. It will simply try connecting for ever but never succeed. I tried this with two routers and a phone hotspot to no avail.

I would be very grateful for any help!

Get a non-broadcom NIC?

Did you try to connect to a 5GHz AP? Try 2.4GHz: https://wiki.archlinux.org/title/Broadc … a)_devices

It will simply try connecting for ever but never succeed

Please don't paraphrase, https://bbs.archlinux.org/viewtopic.php?id=57855
*What* will try to connect and do you get any output from either that tool or the kernel (dmesg -W)?

In doubt, please post your complete system journal for the boot:

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

You can use https://wiki.archlinux.org/title/Tethering to get network access - otherwise redirect the journal onto a USB key and usb-walk that to a system w/ network access.

- I have an intel one but I do want to use this one.

- I forgot to tell, that's what the Phone's Hotspot was for, so the issue is not due to trying to establish a 5GHz connection

- Here is something I found in the dmesg, though dmesg -W didn't give an output for me (maybe I did not wait long enough though):

[    7.551750] rndis_host 3-3:1.0 enp0s20f0u3: unregister 'rndis_host' usb-0000:00:14.0-3, RNDIS device

[   23.548692] ERROR @wl_cfg80211_scan : 
[   23.548696] WLC_SCAN error (-22)

- I have uploaded the entire system journal here: http://0x0.st/H9Xw.txt
What I did in this session: Boot the system, connect to my phone's HotSpot, manually disable WiFi, connect using USB Tethering (so that I can write this message).

USB Tethering was my way to get internet access until now by the way. It just isn't that comfortable on a laptop though.

Disable https://wiki.archlinux.org/title/Networ … domization (then reboot to reset the system)
In doubt, disable NM, reboot and try to connect w/ wifi-menu from the netctl package.

I did so, which sadly didn't help though. I did not want to disable NetworkManager yet since I do not want to mess too much with my fresh install.
All I could gather was the following from dmesg.

sudo dmesg | grep wl
[    2.817697] wl: loading out-of-tree module taints kernel.
[    2.817703] wl: module license 'MIXED/Proprietary' taints kernel.

That's meaningless, what config did you actually add?
Please post an updated system journal.

Peam269 · 2023-08-23 23:09:10

I created the new file

/etc/NetworkManager/conf.d/wifi_rand_mac.conf

and added the following contents to it:

[device]
wifi.scan-rand-mac-address=no

Here is the updated system journal:

I can scan for networks but not connect to them. It will simply try connecting for ever but never succeed. I tried this with two routers and a phone hotspot to no avail.

Did you test all or just one of them?

Aug 24 01:07:25 RazerBlade wpa_supplicant[528]: wlan0: WPA: Failed to set WPA key management and encryption suites

Or all all of them WPA3? Can you configure them to wpa2?

Peam269 · 2023-08-24 10:59:12

You are correct, the issue was with WPA3. My routers had WPA2/WPA3 configured and for some reason, it defaulted to WPA2. Setting WPA/WPA2 Personal did the trick.
Now, I want to know if there is any way to completely remove the WPA3 functionality or prevent linux from using WPA3 whatsoever in any case since manually setting this up for every new wireless access point is quite an inconvenience for me.
Ontop, should I now try re-enabling MAC address randomization?

seth · 2023-08-24 12:47:27

I'd postpone the mac randomization until you've wpa3 under control to not deal w/ 2 pot. issues at the same time.
