"About this phone" shows wrong MAC for WiFi

[Paweł Stołowski]

Wifi-address shown on "About this phone" page is the address of 'ifb0' network device. I've network MAC filtering enabled on my router and this MAC doesn't seem to be the one visible to the network. I had to manually obtain the MAC of wlan0 network device to get wifi networking working on my phone with MAC filtering. So, it seems to me like a wrong MAC is presented to the user.

on mako its getting address for rmnet1

Confirming to land as the feature is totally useless without the fix

Hi.
There has been some kind of problem with the new version (R16) and now the wifi mac address is not shown in "About this phone" settings.
Please, could you check this as soon as posible?

[Pat McGowan (pat-mcgowan)]

I confirmed that on krillin with WiFi disabled no address is displayed but with WiFi enabled it is
On mako the address is displayed whether or not wifi is enabled

[John McAleely (john.mcaleely)]

@Noemi, I see them on two handsets running #16, in about this phone, as I would expect. What happens on the handset with the issue if you flash an earlier release?

[Ken VanDine (ken-vandine)]

I've confirmed this is a krillin specific bug, the about panel uses QtSystemsInfo to get the device information. Visibily is set based on:

visible: network.networkMacAddresses.length > 0

So QtSystemsInfo thinks there are no networkMacAddresses. Perhaps something at the driver level and they way we disable/enable the wifi device.

[John McAleely (john.mcaleely)]

I've raised bug #1417222 "Wifi MAC address only shown when wifi enabled" to track this.

[Pat McGowan (pat-mcgowan)]

The device is removed rather than merely made unavailable

krillin:
Feb 2 17:53:31 ubuntu-phablet NetworkManager[1448]: <info> (wlan0): device state change: activated -> unmanaged (reason 'removed') [100 10 36]

mako:
Feb 2 13:49:08 ubuntu-phablet NetworkManager[1385]: <info> (wlan0): device state change: activated -> unavailable (reason 'none') [100 20 0]

so I would conclude there is nothing to be done at our level

[Ricardo Salveti (rsalveti)]

When wifi is disabled, it calls the Android wifi HAL, which then disables it for real. On krillin, that basically removes the interface on the kernel side, which can be verified with a simple ifconfig.
