Bandwidth Being Limited - But Where?

We have a set of CAPs running off a 3200XM, version 6.4.3.4, that seem to be limiting the bandwidth, but the user role is set with Up and Down to "Not Enforced".   (Security > Access Control > User Roles).   

 

When we have a tech in the field connect directly to the switch in the field, he gets speeds of around 15 Mbps up and down, but when he connects to the WiFi from the CAPs (AP-275s), his speed for down drops to around 7 Mbps while the upload is around 14 Mbps.  

 

Is there any other places in the 3200 that may be throttling the bandwidth other than the User Roles?   I want to cover all the bases in the controller before they tell me all their stuff is good and the problem is in the controller or the AP.

Are you Dropping Broadcasts and Unknown multicast on your Virtual APs?

  Wireless will of course always be slower than wired due to the half-duplex and shared nature of the medium...

But that seems like a lot less, and just on the download side.  

Per the controller, there is high interference on the channel.

Yes.   "Drop Broadcast and Unknown Multicast" is checked under Configuration > AP Group > Edit > Wireless LAN > Virtual AP.

Do you have more than one AP?

Is the client operating on the b/g band?

Yes, there is more than one AP.  We have a mesh config setup and have been testing off the portal and two other points.

In RF Management, the 802.11a radio is setup with a mesh profile and the 802.11g radio is set to default.

You didn't mention mesh.

 

What is the speed that you should be getting?

Should "Channel Quality Aware Arm" be checked for both/either of the radios?   Currently, it is not check for either of them.

It should not really be a factor here.

 

Why are things limited to 15 megs?
