major internet problem!?

[Caitlin]

Ok so about a week ago I went to update java. It said I was not connected to the internet when I was. This was also happening with guild wars 2 and a couple other things that require and internet connection to install. Now today, I can't do that on top of not being able to use my internet browser at all. My laptop is connected to the internet.

To sum it up:
1. I'm connected to the internet and it works fine with things already updated and installed that require an internet connection.

2. I can't install aanythingthat requires an internet connection.

3. I can't use my internet browser at all.

4. I have chrome. I dont think this is the problem.

5. I have talked to comcast and it has nothing to do with them. Its something to do with my computer.

6. I've looked on some other website and have not been able to find anything except to reset my ip adress and I've done this. I've also uninstalled constant guard, this was also suppose to fix both of my problems.
