How do I get my wireless network working?

Question

I recently installed a Microsoft 802.11g integrated wireless router in my home. I only have a laptop which I want to use to get internet connection wirelessly around the house. The laptap is a HP Presrio 2500 and came pre-installed with a 802.11b card. I am not able to get wirless connection even when I am right next to the router. Not sure what I am doing wrong. Do I need to turn on anything within my computer (e.g. switch the 802.11b to "on")?

Overall performance is the result of a combination of factors. Generally, Wi-FiÂ? networks can transmit at speeds up to 54 Mbps. However, actual speed and range may vary depending on such determinants as:

1. The type of radio technology.

2. The number and size of the physical barriers within the network.

3. Any interference to the radio transmission.

The security and performance of any wireless device on a network is greatly affected by the environment in which it is used. The following placement recommendations will help you achieve the best wireless range, coverage, security, and connection speed from your wireless devices:

Place your base station, gateway, or router near the center of your intended wireless network area. This will minimize the possibility of eavesdropping by neighboring wireless networks.

Place wireless components in direct line of sight to one another, if possible.

Place wireless components on desks or shelves when possible (instead of on the floor) to avoid obstacles and achieve better reception on upper stories of buildings.

Avoid placing wireless components in a way such that large, solid objects block the direct path between them. Building components, such as fireplaces, concrete or masonry walls and floors, metal framing, UV film, and metallic paint will reduce radio signal strength.

Avoid placing wireless components next to large metal object such as computer cases, monitors, and appliances. Metal objects reduce signal strength.

Avoid placing wireless components close to electro-magnetic devices, especially those with frequencies in the 2.4-gigahertz (GHz) range. Devices such as cordless phones, microwave ovens, radios, and televisions may interfere with wireless transmission.

If you notice poor connection speed in an area, try moving your wireless components closer together. Connection speeds will be slower if your wireless components are very far apart from each other on the network.

Be aware that wireless signal speed and range can be affected by interference from neighboring wireless networks and devices.
