The IAP-205 is a 2x2:2 access point, which means that you can have up to 2 spatial streams. Following the
mcsindex, you would get a maximum connection speed of 173Mbps for 20MHz channels (used on 2.4GHz), 400Mbps on 40MHz channels (5GHz) or 867Mbps on 80MHz channels (5GHz).
That is with a 2SS client and under optimal conditions, and in that case you would get roughly half of the connection speed if you do a speedtest (due to protocol overhead and half-duplex). This is not because of hardware/Aruba limitations, but just how WiFi works. If you get 200Mbps TCP throughput (Speedtest) on an AP205, I would consider that more or less expected. If your clients are less capable, or RF conditions are suboptimal, speeds will be slower. Also with WiFi your latency is higher than on a wired connection, which slows down tests with a single client that does a single TCP connection.
Unfortunately, WiFi throughput is not an exact science. But because you did not share with what client (specs), on what channel, SNR and channel-width you are testing, it's hard to tell something useful about what you see.

THIS is the EXACT same problem (limitation) I'm having w/my iap205's (AND iap207's)... on wifi w/basically same settings or any other tweaked settings, i get the same limitation you do of <200Mbps... MAYBE 300 max...
I'd have the ap wired so the backhaul is not via wifi... if it's on wifi backhaul, then the speed cuts down to maybe HALF of when on wired or less... i forget the exact number bc it's been awhile since i've tested on wifi backhaul.
@cjoseph @cjoseph is this a limitation of aruba's hardware for the 200 iap models??

Understood - when I was doing the test, I was the only person using it...Is there a document that explain the best practice for all configuration parameters (I have 3 AP-205) or can you do me a big favor and look at my settings? thanks Dov
