Hi to all.
My wireless card is not able to connect to any (protected or unprotected) netword after resuming the system in case of SUSPEND or HYBERNATE. I had the same problem in Jaunty as now in Karmic. The problem persists when using Network Manager or WICD.
I notice that (not in case of SUSPEND or HYBERNATE) turning the wifi off and then on doesn't cause the problem. I mean, everithing works perfectly in case of deactivating wireless using WICD or pressing the wireless button of my Acer Aspire 5730z, when not resuming my system from a SUSPEND or HYBERNATE condition.
On the other hand, in case of having resumed the system after SUSPEND or HYBERNATE, I see that even disabling/enabling wireless make it work. Nor logging off and back on the current user.
Any suggestion please?
