wifi work only in debug mode

[Giovanni Maria Lombino]

I installed in a notebook packbell android rc2 but the wifi only works if I start debug mode, if I boot in normal mode it does not work it does not find networks.

debug mode is here/
https://raw.githubusercontent.com/GMLombino/packbell/master/debug%20mode
normal mode is here/
https://raw.githubusercontent.com/GMLombino/packbell/master/normal%20mode

how can i solve?

[Jon West]

Try adding the AUTO_LOAD=old flag in Grub, since debug mode does use modprobe, this might make a difference on your device

if i add AUTO_LOAD=old the wifi works, but on reboot no. how can i make the change permanent?

thank you

I usually edit it from my working Windows install. Check the "Custom Install For Bliss OS 8.x/10.x/11.x UEFI/ESP (64bit)" section of the second post on the Bliss OS XDA thread for more details on how I typically do that.

We use the same method as Android-x86 releases, so the method will cross over fine.

which -rc2?

Anyway, you should not use the obsolete ??-rc2.
Please update to the stable release, say 8.1-r1.

It's interesting to see the report.
In normal mode the wl driver is loaded.

[ 3.534368] wl: module license 'MIXED/Proprietary' taints kernel.
[ 3.534372] Disabling lock debugging due to kernel taint
[ 3.976071] wlan0: Broadcom BCM4727 802.11 Hybrid Wireless
Controller 6.30.223.271 (r587334)

However, in debug mode there is no the third line shown above.

Let me guess. In normal mode the wl driver is used but it doesn't work.
In debug mode another workable wifi driver is used.
What's it? Please open a terminal and type the command:

ifconfig wlan0

To workaround it, could you try to edit /system/etc/modules.blacklist
to add this line (system must be read-write):

deferred wl

This will defer the wl driver loading after all other modules.

hi Chih-Wei Huang, in debug mode, this my  ifconfig

x86_64:/ # ifconfig wlan0

Unfortunately this doesn't show what driver it is.
Are you using 8.1? If yes, please type

/system/bin/ifconfig wlan0

Alternatively try the command:

readlink /sys/class/net/wlan0/device/driver

[Giovanni Maria Lombino]

x86_64:/ $ su

x86_64:/ # readlink /sys/class/net/wlan0/device/driver

../../../../../bus/bcma/drivers/brcmsmac

x86_64:/ #

I hope it is useful

So in debug mode brcmsmac is used but in
normal mode the incorrect driver wl is used.

As I've suggested, the simplest way to fix it is to
defer the loading of wl driver.
Add the line to /system/etc/modules.blacklist

(system must be read-write):

deferred wl

Or to disable it completely:

blacklist wl

Let me know if this works.

[Giovanni Maria Lombino]

I added both deferred wl and blacklist wl in /system/etc/modules.blacklist, but the wifi no work.

I started again adding AUTO_LOAD = old and so it works and this is its dmesg:

OK. Seems brcmsmac doesn't be auto loaded by ueventd.
I recall someone reported a similar issue before.

Could you boot to debug mode, type 'exit' once,
then copy the /tmp/log to usb disk and upload it somewhere
so I can check. Thanks!

[Giovanni Maria Lombino]

Sorry which command I have to use to copy the log

mount /dev/sdc1 /hd (suppose the usb disk is at sdc1)
cp /tmp/log /hd
