No wireless network after resume from suspend

[Tero Karvinen]

Binary package hint: wifi-radar

Wifi-radar fails to restore network when computer resumes from suspend-to-ram (S3). If wifi-radar is configured, user can restore the network with
$ sudo wifi-radar -d
or
$ sudo /etc/init.d/wifi-radar restart
Annoyingly, this requires typing your password again for sudo.

Bypass:
/etc/acpi/resume.d/63-wifi-radar.sh
#!/bin/sh
# Find any WLAN station to connect to. Requires a configured wifi-radar.

# Restart wifi-radar service if it set to run on this runlevel
# Todo: use actual run level number instead of hardcoded 5
# Todo: notice rcN.d script even if the number after S is different.
if [ -x "/etc/rc5.d/S20wifi-radar" ]; then
        /etc/init.d/wifi-radar restart
        # touch /tmp/wasrun-resume-d-63-wifi-radar-sh
fi

While suspending, Ubuntu removes wifi driver from kernel. That results in
wifi-radar being unusable on wake up. This is handeld
trough /etc/default/acpi-support. There is a line:

STOP_SERVICES="mysql "

replace it with:

STOP_SERVICES="mysql wifi-radar"

Report results. Thanks.

It works using STOP_SERVICES="mysql wifi-radar", thanks.

I guess this fix is hard to add to wifi-radar package, as /etc/default/acpi-support is from a different package. Maybe this STOP_SERVICES bugfix could be done on all machines, even those that don't have wifi-radar installed, because adding non-existant services to STOP_SERVICES does not seem to cause any problems.

I'll talk to Matthew about that.

Status was changed to rejected, even though change comment is about trying to fix the issue. There is a bug, there is a bypass, there are no unanswered questions. Changing back to unconfirmed.

Could you test this (sleep doesn't work on my laptop :/)? Save it as /etc/acpi/resume.d/63-wifi-radar.sh and chmod it to be exec. This is based on your script, but with style other scripts are done :):

#!/bin/sh

if [ -x /etc/init.d/wifi-radar ]; then
        /etc/init.d/wifi-radar start
fi

Thank you.
