My computer has limited or no connectivity. I don't know how to make it work... I've done EVERYTHING! Please please please someone walk me through this

First this is neither a chat or instant messaging. We do not allow chat speak (idk) here.

Second, if you are done "everything" then how can we help?

For us to help we need to know how you connect, what/who you are connecting to, what messages you get, and what you have tried and what happened when you tried.

Limited or no connectivity to what? A hub, switch, router, PC or what?

If it is your router, reset your cable/dsl modem, wait a minute and then reset your router (unlug from power and plug it back in).
