AIR-LAP1142N-E-K9 and radios

Hello all,

the AIR-LAP1142N-E-K9 is a dual-Band 802.11a/g/n. This means it can transmit both a, g and n, right? I did a load stat using the WCS on this AP, and I don't understand the grouping of the radios.

The WCS shows the AP twice, as a 802.11a/n and as a 802.11b/g/n. What is the actual radio that the stats are for? The a/n radio has much more clients than the b/g/n radio. How do I see what radio the clients use the most? The reason why I ask is because I have two AIR-LAP1131AG-E-K9 in the same room, and they have 5 clients each, but the 1142 has 14-16. I suppose it's cause the clients prefer the 802.11n radio when searching for wifi?

The stat options on the WLC (running sw 7.0.98.0) has no separate option for listing the n-radio - only a and b???  :

(Cisco Controller) >show client AP ?             

              

802.11a        Display information for 802.11a.

802.11b        Display information for 802.11b.

802.11-a49    Display information for 802.11a-4.9GHz.

Output (yes, I know the WCS-stats differ from the WLC-stats):

(Cisco Controller) >show client AP 802.11a S01-035

AIR-LAP1142N-E-K9 and radios

WCS will display the AP's based on their radio, so any dual band AP will have an 802.11a/n & 802.11b/g/n listing in WCS; this is because they are physically seperate radios, antennas, and processors.

As for clients chosing the 802.11n AP's this can be for a number of reasons; bandwidth, protocol, signal strength, etc...

So it's can be tough to predict or justify why a client selected the AP it chose, as for the stats though, I am not sure what specifically your looking for. If you are just looking to see which radio is busiest there is a WCS report that should give you that information.

HI guys can you config suninterface on AIR-LAP1142N-E-K9 ?

AIR-LAP1142N-E-K9 and radios

If you convert it to run IOS then yes, you can configure it just like any other AP with multiple SSID and radio subinterfaces.
