I have a wireless connection in my house. It has been set up for 4 years already. Sometimes I have problems with my connection, but it works for the most part. I have been tring to get onto the internet for the past 2 days, and cannot. The small internet connection icon at the botton of the screen says I have an excellent internet connection, but when I try to get out it says I need to connect to a network. Does anyone have any suggestions?
