While wireless Internet technology allows us greater mobility in the home and around town, you may also encounter issues with getting a good signal. This common problem has a variety of origins and also depends on your connection method.

"Wireless Internet" can refer to two different things: a person using a laptop modem card to communicate over a cell phone network, or an environment where the computers are connecting wirelessly to a nearby high-speed modem.
Laptop Broadband Networking
The user with the laptop modem card can resolve the issue the same way a cell phone user does, since they are connecting to a cell phone network: Find a location where you can get stronger signal strength.
Mobilizing for Signal Strength
Terrain can block the laptop user from "seeing" a nearby cell tower, and buildings in an urban environment, like at a coffee shop or at an airport, can cause the same problem. In both cases, seeking higher ground or more a more open area can improve your signal.
In the home, Wi-Fi access is at its strongest when there is not a wall or floor between you and your modem. Sometimes a microwave or cordless phone will also interfere with the signal.
Drivers and Viruses
Updating your drivers--packages of software that your computer uses to recognize its hardware--can solve performance glitches. You can also use an anti-virus program to scan for malicious programs that could be interfering.
