Encryption Enabled/Disabled; Device Out Of Range - Cisco AIR-BR350-A-K9 - Aironet 350 Wireless Bridge Hardware Installation Manual

Checking Basic Settings

Encryption Enabled/Disabled

Verify that the wireless devices are using the same encryption setting as the bridge. When encryption is
enabled, the bridge uses 40-bit or 128-bit encryption. If enabled, the wireless device must support the
same setting. If the wireless device does not support 40-bit or 128-bit encryption, you must disable
encryption.

Device Out of Range

The bridge supports a limited communication distance with wireless clients. When a wireless client
exceeds this distance, it cannot communicate reliably with the bridge. Indoors, this range is typically 150
feet at 11 Mbps or 350 feet at 1 Mbps when using an omnidirectional 2.2dBi antenna. However, internal
building structures might interfere with radio communication, dramatically reducing communication
distances.
If basic radio parameters in the bridge and the wireless client are set correctly, communication problems
might be related to structural interference or distance from the bridge. To isolate these problems, move
the wireless client close to the bridge (able to see the bridge antenna), and attempt to associate with the
bridge.
If the bridge is using a high-gain omnidirectional or directional antenna, the antenna radiation pattern
Note
may prevent communications with close devices or devices on the edge of the radiation pattern.
Typically, high-gain antennas compress the radiation pattern in some directions to increase the gain in
other directions.
