Re: Mac andom does not work with wl driver

[Bhasker C V <bhasker unixindia com>]

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.

 I tried b43 driver and the performance was very poort for my BCM4331  (macbook pro) wifi. Hence I moved to wl.

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.
