How long does wow take to load with a actiontec?

Answer 1

It should load in less than a minute, considering that's a function of your PC, not your wired or wireless connection. However, downloading the game, content or patches might take longer, again depending on your internet quality - this can take anywhere from 2-8 hours.

On the whole, this is the limiting factor to (down)loading, and not really the wireless connection. You might suffer from lag if you have a slow connection to your router, but this connection generally processes more data than your connection to the internet, so you shouldn't have many issues with it.
