One of our clients has got a 1200 cisco AP which is their only way of connection the network (no RJ45 cabling is present in their office). They are complaining about the slowness of their network, so first I thought that it is simply a problem with too many users connecting to the same AP, but when checking the interface outputs, I found that the tx/rx=1/255. At the same time I found that there are plenty of output errors on the Dot11Radio0 interface. There are also a few interface resets. Then I checked the logs and I found that there are plenty of maxretries reached messages.
I read a few forums and they say that this might have something to do with interference. Then I ran a carrier-busy test and that showed a number under 20 for all channels, so I belive it is not the problem.
I attached a file with the outputs in case you would like to see what I am talking about.
Thanks for any comments in advance and please let me know if you need any more information.
