We have 121 extreme APs and our biggest complaint is poor wireless speeds. We use Extreme AP3825i aps for the most part. I have noticed that one of our APs is producing far less throughput than an AP with the same settings much further away. 80 mbps vs 5mbps at 20/40mhz channel width. This is just an example we normally run our APs at 20 mhz on the 5ghz. I wonder if this is a sign that the AP has gone bad? If so is there anyway to tell if other APs have gone bad without connecting to each one and running an iperf? I have shutdown the AP and rebooted it. It has the latest firmware. Another note we have set channels based off a site survey and I am using the Ekahau site survey software.
With a high number of wireless APs in the building should I turn on auto power so that I cant see more than a few APs at a time? Will turning the power down reduce throughput speeds? Would you run your 5 ghz at 20/40/80 mhz? The max number of clients on one ap is in the 20's we total right around 550 guests on our network. How would you start to tackle this problem?
