I had Antergos on my old Lenovo Yoga 900S and I decided to reinstall OS to EndeavourOS.
On EndeavourOS wifi is not working, but what’s happening is weird.
02:00.0 Network controller: Broadcom Inc. and subsidiaries BCM4350 802.11ac Wireless Network Adapter (rev 08)
Offline install fresh start I do
interface is present and I can connect to AndroidAP wifi but not my Unifi wifi.
After pacman -Syyu and restart broadcom is not visible in lspci… I have to make reboot to bios, click F10 and reboot and wifi lcpci is showing broadcom again.
But after this update brcmfmac is saying:
chip backplane type 15 is not supported
So I decide to check broadcom-wl . It is installed by default, so I added just blacklist for brcmfmac.
It is saying that I tainting kernel if trying to load by modprobe wl.
After reboot now Broadcom card is visible in lspci as:
02:00.0 Non-VGA unclassified device: Broadcom Inc. and subsidiaries Device 8100 (rev 08)
I read it all.
I checked it again. If I unload wl and load brcmfmac my wifi card is visible in NetworkManager.
Unfortunately I can’t connect to my home network.
I created second ssid with no extra unifi staff enabled and then I can connect. I see that I got 24Mb/s max speed so I guess unifi is disconnecting laptop because of unstable/slow connection.
I’m slowly starting to think about just buying another wireless card…
after uninstalling interface appears properly! thank you!
any idea why I cannot connect to my main ssid?
it is called 11ska. I can connect to second ssid called hass on 5GHz.
Only difference I see is beginning of the generated MAC address by unifi.
Do you have it configured for a different SSID for the 2.4 Ghz and the 5.0 Ghz?
Edit: Normally you would have it configured for the same SSID but some people may not if they have a poor connection issue for some device maybe?
Edit: 2 I would try changing the router to a different channel. Not sure what country you are in. 11 is pretty standard.
I have configured it as same SSID for both channels.
I’m in Poland. I think it cannot be issue with the channel as second SSID is on same channel and it is working for some reason…
it can connect on Windows if it says something.
Found reason. Broadcom does not connect to network if Unifi fast roaming is enabled.
I guess I’m gonna need to use this second SSID for this card.
