The router can do that. To avoid, you have to disable “allow DHCP to
change host name” or similar phrase.

I sometimes see that, on a laptop with Intel graphics. In my case, it seems to be a graphics driver problem.

I set the KDE power manager to never dim the screen (but turn off is allowed), and that greatly reduces the chance of it freezing.

Your problem might be different, but it probably is a graphics problem.

openSUSE 13.1 Gnome

(a) freeze

ADSL/2 through Thomson TG782T Gateway

Settings - Power - Power Saving - Blank Screen = 5 minutes
Settings - Power - Power Saving - WiFi = OFF
Settings - Power - Power Saving - Mobile Broadband = OFF

Suspend & Power Off - Automatic suspend = OFF

So far works fine.

(b) HOSTNAME change

Makes sense :slight_smile:
