I can't get WiFi working on a master build from today (1.4.0.0-prerelease, platform version 290a1,  commit info 00c1426b). The device failed at detecting WiFi network (actually, it doesn't time out, it just loops).

In dmesg (see attachment) you can read:  

<3>[    1.640714] power_supply wireless: driver failed to report `present' property: 4294967274
and
<3>[  124.167526] wcnss_wlan wcnss_wlan.0: Peripheral Loader failed on WCNSS.

(last message comes from https://android.googlesource.com/kernel/msm/+/android-msm-mako-3.4-jb-mr1/drivers/net/wireless/wcnss/wcnss_wlan.c)

Precisions: no SIM card is inserted in the phone, NFC is enabled.

Adding a logcat output at boot time

It is failed in loading wifi driver during booting procedure.

From dmesg,
...
<6>[  140.118815] wlan: loading driver v3.2.2.17
<3>[  140.118876] wlan: [497:F :HDD] hdd_driver_init: WLAN device not found!!
<3>[  140.118998] wlan: driver load failure

For logcat, phone cannot get wlan0 device.
D/NetUtils(  173): failed to remove default route for wlan0: No such device

Could you please make sure the wifi of your nexus 4 is workable?

[Stephanie Ouillon [:arroway] (needinfo me)]

Sorry Ken, I don't have the phone anymore to make more tests.

Comment 6

[Dietrich Ayala (:dietrich)]

A friend of mine found that he had to revert to Android 4.3 before flashing in order for wifi to work. Said it solved some other problems as well.

flashing from a base 4.3 build fixed this
