I have just installed Ubuntu 12.10 on my PC Lenovo B570e. I have WiFi connection in my room. It continuously connects and disconnects. What should I do?

If WMM is activated in your router, disable it.

When connecting to the console of your router with your browser you will find in the WLAN settings a conmboxbox to UNCHECK WMM.

WMM is Wi-Fi multi-media, a setting in modern WLAN routers you can switch on or off. It usually only causes trouble, at least in my experience, when switched on. (I had a similar problem and this solved it.)
