Determining Received Signal Strength of an Access Point

[Scott Spencer]

Hello All,

I am setting up a wireless bridge between 2 points in a very large warehouse using 2702E access points with AIR-ANT2566P4W-R directional antennas. The access points are running in autonomous mode. Is there anyway to determine the strength of the received signal?  I could not find a RSSI value anywhere in the GUI interface. Is there some other method to determine the signal strength?

Thanks

You can SSH/Telnet and issue 'show dot11 associations' to see the associated bridges, take note of the neighbouring AP MAC address and then issue 'show dot11 associations %mac-address%' to get verbose information about the neighbouring bridge/sv including RSSI.
