What is a historical connection?

Internet Connection just won't give, what can be the culprit?

• Scenario: Apparently it would seem that regardless of how many times I try to browse the internet, I just cannot get a single website. Prior to this situation I always had a valid internet connection. I was able to use the internet in home and in school, after signing. Everything was grand but now I just cannot use the internet. At first I thought the following: 1.) Virus, I have avast!Antivirus fully updated and not a single critter has entered my laptop. 2.) Internet Connection, I am fully connected on school and home, I have the classical 5 bars, excellent connection for my laptop. 3.) Troubleshooting indicated "problems with wireless adapter or access point," in school however people can still use the internet on their laptops The problem is that I cannot browse the internet at all, despite having a valid connection. I believed at first that perhaps my older brother was to blame since I saw him configuring the modem on the PC, I noticed since I was somehow disconnected and he was still online and was on a modem informational website (AT&T 2Wire..., wireless modem), after I turned my laptop off, if he is the culprit man do I want to kill him. Later I couldn't use the internet on the PC when he was not there, this happened about 2 days after that sighting. I believe that **** might be behind this. Problem is that I can connect on both places but not browse the internet on either or. I apologize for the length, the specs on my laptop are Windows 8, HP laptop, and avast! Antivirus. Question: What can I possibly do to browse the internet if I can connect to the network (at home and school) ? Internet Explorer and Mozilla Firefox keep giving the "unable to connect" eventhough I have excellent connection.

• Answer:
