Hello everybody!
I’m a new openSUSE user and so far it has been a nice experience… except for this.
The problem takes place (apparently) after downloading a certain amount of data (~200-300mb). After that, the wifi stops working and it disconnects.
But this gets odd to me: my network doesn’t show anymore on the networks list. After, like, 5 minutes, my network shows again but it is impossible to connect to it.
It seems that the router is doing something like blocking my laptop because, when I try to reconnect, the router doesn’t assign an IP to it.
The only solution is restarting. And the cycle continues.
I can’t say if this happened with another SO because this laptop is new and was Free DOS.
Do someone knows how to fix this?
Greetings.

You should post the result of this so we can what your hardware is:

Looking around the web there might be some issues with your device
eg: http://ubuntuforums.org/showthread.php?t=2104129#top
Well, yes, that was the problem.
I found the solution in this same forum and it was easy. I just used this two commands (I don’t know what they do 
)
zypper ar http://download.opensuse.org/repositories/Kernel:/stable/standard Kernel:stable
and
zypper in --from Kernel:stable kernel-desktop
And picking Desktop - openSUSE on the booting section.
