I've been having numerous problems with connectivity through WiFi. It had been working for a few days and now it doesn't. On top of that around 40% of every time I turn on the laptop it shows "System running in low-graphics" error and I'm unable to view the desktop (sometimes not even able to access terminal), therefore having to manually power-down until it finally works. I use Ubuntu 12.10.
