Customer has a Cisco AP (AP1131) deployed in his cafe. However, due to the high volume of wireless density usage, users often find slowness in surfing the websites. The AP is deployed in standalone mode (w/o WLC). There seems to be no bottleneck on the internet bandwidth pipe, where the wireless network is connecting to a 10Mbps internet of the Service Provider.
Customer is querying if he could generate some concrete reports/proof to justify to his management that there is a bottle neck for the user to access wireless internet at his cafe.
Is there anything we can do on the AP to show the congestion within the AP?
Does it show us the speed or signal strength of each client?
Yes it does. If you put the client MAC address at the end, like "sh dot11 as " look for the value of "Signal Strength" and "Signal to Noise ". Another thing to look out for is the proliferation of 802.11b (2.4Ghz). Maybe something else is operating at similar channels and you need to sniff the air and change the channels to your AP.
The thread of what he says leolaohoo, It´s more probably that you have a lot of interferences or noise from the others 802.11devices (aps from another shops or coffee shops) or no 802.11 device ( for example a microwave oven could you break your conections).
If you can make a survey using a Spectrum expert you will more information about the issues you can be affected.
I suggest you configure the following command to allow to the Ap to be able to change to the least congented channel. (at interface level).
"channel least congested 1 6 11" This command allows the ap to change the channel between the 1, 6 or 11 channel searching the least congested at any time.

This is the start of a display filter cross reference between Wireshark and OmniPeek.
The 1st installment is a table of advanced filters. More filters will be added as time allows.

The script should be completely self explanatory.
