Boost for Internet Calls
-- Problem: Your signal has a habit of crashing in the middle of VoIP calls.
-- Solution: You can buy new hardware, such as a more powerful network adapter or router -- those dubbed wireless-N are said to have twice the range, and up to five times the speed, of standard wireless- G routers. But there also are things you can do free of charge. Start by resetting your wireless router to a different channel -- interference from other devices using the same channel is a likely cause of unstable connections. In the U.S., channels are 1, 6 and 11, and they can be changed through your router's configuration page (your computer will automatically detect the new channel). If you have a cordless phone or other wireless devices, place them as far away from the router as possible. Since walls also interfere with your signal, the apparatus should be centrally located in your home. Metal objects, like file cabinets, can also get in the way. Regularly check for software updates from your router's manufacturer, which can improve performance. These updates are generally available at no cost.
