"Sometimes, changing the direction of the router can also improve dead spots. Try slightly changing the position of the router by 90 degrees, for example. That might help in improving coverage. It (coverage) is not a complete circle," he said.
Older Wireless G routers may experience interference with microwave ovens, garage remotes, baby monitors and Bluetooth devices. If your G router is near any of these devices, move it. Also, storing it in the closet could weaken the signal, too, because the more walls the signal must penetrate, the weaker the signal gets.
Keep it close.
If Internet can be piped into your house from multiple rooms (which can be the case with cable Internet), pick the room where you rely on it the most, says Albertson, with Linksys.
Traditionally, customers reported to Linksys they kept their router in the den or office, near the computers. But more recently, it's in the living room next to the TV, where consumers are streaming HD video. "It will deliver a better experience on that device at the expense of the far-reaching bedroom," he said.
If signal doesn't reach expected parts of the house, accessories could improve the router's coverage. Extenders, usually placed at the edge of a router's range, repeat the wireless signal further to get it to dead zones. Amplifiers, which attach to the router itself, boost the wireless signal. The non-wireless Powerline technology (also known as HomePlug), which sends data through the home's electrical wires, enables users to plug in Wi-Fi access point or extenders into any wall socket and create a Wi-Fi hotspot.
Some older routers got a new life thanks to the open source community. DD-WRT, available free at
, is a Linux-based firmware that can extend the router's life.
It replaces the software of more than 200 devices, allowing users to tweak router settings for better bandwidth management, performance and transmission. You'll be able to increase the transmit power on older routers to improve wireless strength. Check the site to see if it'll work on your old router.
When a wireless router does quit working, it may still work as a wired router. Those megabit or gigabit Ethernet ports on the back can still move data throughout the house faster than most Wi-Fi. Use it to plug in printers, storage drives and even desktop computers.
