Helps! The Internet!

[woodside]

I'm having some uber-huge Internet problems.

The wireless network I share with my room mate has stopped allowing me to get on-line. However, I am still able to get on-line via my neighbor's wireless.

What's the deal here? I'm able to connect to our network, but I can't get iTunes/iStore to work, nor Mozilla, IE, or AIM. It sounds like a virus or Adware, but neither Adware nor Norton is picking up anything.

Suggestions?

Usually there are two possible causes for this, either a change in the settings of the computer or a provider problem.

Did you install / modify anything just before this happened? If not, it will most likely be back on its own in a few hours, but you can try calling the help service of whoever provides the connection.

It's unlikely to be a virus, since they usually cause bigger disruption, but download and try a scan with this www.free-av.com/, it came up second in the recent antivirus quality list.
Norton is a pretty bad one, because it's pre-installed in most pcs, and so hackers build their creations to work a way around it.

Since it's wireless, another possibility is that somebody in the neighbour is hacking at your connection and using all your bandwidth, preventing you from connecting. In this case, not much can be done from your end.
