Thanks for the testing.  All B2 XO-1.5 machines (virtually all of the ones distributed outside of OLPC) cannot resume properly after suspending.  The WLAN will disappear and won't come back until you reboot.  This sounds exactly like the symptom you're seeing.  It's been fixed on later hardware and will be fixed in the production version, but it will never work properly on a B2 machine.  If you need WLAN access after suspend/resume (which will indeed occur after a "brief inactivity") use the Sugar Control Panel / Power settings to disable automatic power management - both checkboxes on that panel should be cleared).  If you don't need WLAN operation, it is helpful if you don't clear this setting, so suspend/resume operation continues to be tested for more bugs.
