WiFi on BBGW stopped after upgrade

[Mark Grosen]

I had a working Debian system on the BBGW. I did an apt-get upgrade today and re-booted and now the WL8 will not initialize. I saw there was a firmware update in the upgrade, so maybe this is causing a problem?

mark@markbbgw:~$ cat /etc/dogtag

Hi Mark,

This is getting better in kernel's such as: 4.4.16-ti-r38

Where the kernel will try to reset the wl18xx and try to re-load the firmware.

But yeah, still working on this annoying bug...

The easy fix is to unplug let it sit for a few seconds and power it back up..

Regards,

I tried that with no joy (had to attach ftdi to get serial console). Is there a newer kernel to try?

Yes, do you know how to use /opt/scripts/tools/update_kernel.sh? Use the lts4.4.
