Bringing back wireless after suspend in Ubuntu Gusty
It’s true that some features of Linux aren’t quite as reliable as their Windows counterparts. For me one of those “nice to have but not totally necessary” features has been Suspend and Hibernate. In the past, I’ve had experiences where either the OS just hangs or never wakes up. However, my new experience is that (with Ubuntu Gusty (7.10)) everything comes back from Suspend or Hibernate EXCEPT my wireless interface. If you’re like me (and everyone else on the planet) your wireless connection is vital.
After some searching on Ubuntu’s launchpad, I found the answer:
Open /etc/default/acpi-support
sudo nano /etc/default/acpi-support
Add networking to the STOP_SERVICES. For me it was on line 61.
Before
# Add services to this list to stop them before suspend and restart them in
# the resume process.
STOP_SERVICES="mysql"
After
# Add services to this list to stop them before suspend and restart them in
# the resume process.
STOP_SERVICES="mysql networking"
Your wireless should now come back after Suspend / Hibernate.
