It looks like I can recover if as root I do a:

dhclient eth0

where eth0 is my wireless interface


I took a look at this opensuse website:

http://en.opensuse.org/Pm-utils

I did try out this s2ram command:

s2ram -f -a 1

(force suspend to ram with acpi_sleep=s3_bios)

Wifi did recover.

It is also possible to set this option in /etc/pm/config:

S2RAM_OPTS="-f -a 1"

I will need to test more.
