There is not one good clue in your post. While I could take shots at it, I hope you could supply at least what the forum note asks for next time.
i have a laptop and when it is plugged in (a/c power) the internet goes very slowly through my wireless connection. the connection to the router is still perfect the internet just moves very slow. As soon as i unplug my laptop from the wall the internet moves much faster. There are no settings or programs that change when i plug and unplug my computer. I am baffled and normally pretty good at solving my own problems. Any ideas?
