I'm guessing by you saying you tried multiple "search engines" you mean "browsers"?
Search engines are Google, Bing, etc.
Browsers are Chrome, Firefox, IE, etc.
Anyway, I think your first step is just to try another computer in the house. That would help determine if it's an ISP issue or router issue. If another computer has no issue, then we can move onto your computer.
It's definitely not that the chat room is busy.
