Our internet service tech showed us a great, free, non-invasive link to check our wifi download speed in any location. Thought this might be helpful both at home and on the road, especially when using free or paid wifi (see if you're getting what you paid for!).
You simply choose the nearest city to your location from the menu, and let it do its magic. We found a variety of signal strengths in our house, from 75 mbps on the front porch in front of the room where the router is, to 9.5 mps in the farthest bedroom - mine, of course! There are signal boosters you can buy (Netgear or Linksys is what he recommended).
