### Analyzing Channel Use

The Intel® PRO/Wireless 2011B LAN Access Point keeps statistics for individual channels (frequencies). These identify channels that have difficulty transmitting or receiving due to retries.

#### To view statistics for individual channels

1. Select Show Misc Statistics from the Main Menu.
2. Select Per Channel Statistics. The display shows the packets sent, received, and retries for each channel.
3. Press any key to continue.

### Analyzing Retries

The access point keeps statistics of packets with multiple retries. Use these statistics to identify severe occurrences of retries. Retries occur when the transmitting station fails to receive an acknowledgment for a transmitted packet. This lack of acknowledgment can result from:

1. two or more stations transmitting simultaneously and causing collisions
2. the receiving station moving out of range
3. the receiving station being powered off

Any one of these results causes both devices to suspend transmitting and retry later. Too many retries can indicate a system problem.

#### To view retry severity:

1. Select Show Misc Statistics from the Main Menu.
2. Select Retry Histogram. The display indicates the packets that experience retries (up to 15 retries).
