I just got a new computer. I connected wirelessly just fine at first. I went online to try and alter things with the connection to make it go faster. After tweaking a few things, I went to use my internet. When I tried it, the pages were all unavailable. I looked at my connection, and instead of saying local & internet connection (or something like that), it said Local Only. Any help would be really appreciated.
