Common problems with wireless connections

Incorrect channel

Although this setting should be configured automatically on most Windows clients, it can be a potential problem if you must configure this information manually. Verify that you are using the same channel as the WAP, and then retry your connection.

Compatibilities

Different wireless standards are always backward compatible. For example, some devices that support 802.11a are often incompatible with devices that support 02.11g

Out of range

If you can't connect to a wireless access point (WAP) or see it in a list of available WAPs, you might be too far from the WAP. Move closer and retry the connection.

Incompatible drivers

If you don't have the appropriate driver installed, your wireless adapter won't appear in Device Manager. Research the computer vendor's website or the adapter manufacturer's website to find the correct driver for your adapter and operating system. If your adapter is not longer supported, you'll need to replace it.

bounce

Wireless signals can bounce off reflective materials, such as windows and metal objects and reduce the strength of the signal. To reduce bounce and the likelihood of signal degradation, make sure your WAPs are placed in a central location and a close to the clients as possible.

Security setting

Incompatible security settings or network keys will prevent a successful connection. Ensure that the WAP and your wireless client have the same security method configured (WPA, etc.) and that you're using the correct password.

Interference from electrical equipment

Move the WAP and the client away from any potential interference caused by electrical equipment that can disrupt radio waves, such as electric fans or other appliances with motors.

SSID mismatch

This problem is likely to occur when you're attempting to join a wireless network by manually entering the SSID because the SSID broadcast has been disabled. Verify that you have the correct SSID, and try your connection again.

latency

the time it takes data packets to reach their destination, is greater in wireless networks than in wired networks. This can cause problems with video or voice transmission, causing skipping or pausing while data is transferred. The best solution to this problem is to limit the use of data-heavy transmission over wireless connections, or to use wired connections for data-heavy transmissions.
