Tell me if this sounds familiar. You're in your bedroom surfing the Web on your laptop or tablet, when suddenly the Wi-Fi signal starts cutting in and out, slowing your connection way down. I know it's happened to me before and it's incredibly frustrating.
Before you restart your router or go buy a new one, however, there might be a better solution. A common cause of Wi-Fi problems is - well - Wi-Fi.
That's right, it could just be your neighbors' networks are interfering with yours. That happens when too many routers are using the same channel.
That's where the program Vistumbler comes in handy. It's a free download that lets you see every network in your area.
Vistumbler shows the network name, signal strength, frequency and more useful info. It can even link up with Google Earth to show you where the routers are located.
You can also see at a glance what channels the networks are using. That allows you to set your router to a channel that isn't in use, or lightly used. Just be sure to stick with channels 1, 6, or 11; anything besides those just causes more headaches. Click here to read how to change channels, as well as four other ways to improve your network.
