Re: Mac andom does not work with wl driver
Hi, I am wondering why the cloned mac is not working. As such this is for sure not a driver issue, since I am able to setup a random mac and able to easiy successfully connect manually using wpa_supplicant. So it is network manager doing something which wl does not like. Could that be unset so that the config generated by networkmanager matches a simple config generated by wpa_passphrase ? Sorry, i dont see a reason why a random mac must have an issue with wl driver. -- Regards, Bhasker C V On Mon, May 10, 2021 at 7:46 PM Bhasker C V wrote: > Thank you very much Beniamino Galvani, > I tried b43 driver and the performance was very poort for my BCM4331 > (macbook pro) wifi.

Re: Mac andom does not work with wl driver
Thank you very much Beniamino Galvani, I tried b43 driver and the performance was very poort for my BCM4331 (macbook pro) wifi. Hence I moved to wl.

AW: AccessPoint 5GHz DFS Channel Radar Detection Failure
Hello, thanks for your answer. I'm creating the connection on band wifi band a using this command: nmcli con add type wifi ifname wlan0 autoconnect yes ssid $(hostname) 802-11-wireless.mode ap 802-11-wireless.band a 802-11-wireless.channel 100 ipv4.addresses 192.168.201.1/24 ipv4.method shared wifi-sec.key-mgmt wpa-psk wifi-sec.psk TEST12345 I had a few problems to bring up the access point first, but when I changed the 802-1x.auth-timeout to 90 seconds (CAC time) and send the correct country code to wpa_supplicant over dbus the access point is coming up as it should. Everything is fine until I need to switch the channel because a radar event is detected by the driver. To simulate the radar event I use a debug feature of the WLink8 driver. I use the debugfs and write the channel to a specific file: echo 100 > /sys/kernel/debug/ieee80211/phy0/wlcore/wl18xx/radar_detection for triggering a radar event on channel 100. We used this in the past with hostapd and it worked really good. I'm not sure how I can tell wpa_supplicant to use wlan0 instead of p2p-dev-wlan0. I only create the nmcli connection and I think the network manager is then configuring wpa_supplicant over dbus. Thanks Nadja -Ursprüngliche Nachricht- Von: Beniamino Galvani Gesendet: Montag, 10.

Hi, this is a known issue, the Broadcom wl driver doesn't work well if the MAC is changed. Unfortunately the driver is closed and so only Broadcom can fix this problem. According to this [1] the 'b43' open source driver supports BCM4331. You could try if it works better.
