Network / Sharing :: Limited Internet Connection - Reconnect To Router

My computer keeps listing the internet connection as "limited". It does this randomly, I don't know when it will happen next. Restarting router/computer fixes it sometimes, but not all the time. Sometimes it takes about 4 restarts of the router until I get a proper connection. Trouble shooting merely describes the problem as having no connection and tells me to reconnect the router. This takes around 5 minutes each time and I'm getting tired of doing this, as it interrupts skype calls, games and conversations.
