slow wireless speeds on ap 105

[along5664]

I have a 650 controller located in my data center, In a branch office we have a ap 105. Between the branch office and the data center we have a 20 mb/s mpls network. When I am connected to the wired network at the branch office I can get the full pipe of bandwidth via speedtest. When I connect to the wireless, I can only get about 2mb/s down and strangley can get anywhere from 2-15mb/s up. I have checked all speeds and duplex settings on the switches. We are not using any qos in our ssid profile, and we are doing tunneling to get the ap to the controller. We are running 6.1.2.6 code. The ap is sitting about 20 feet in the next room from my computer.Full signal and nothing around. Anyone got any suggestions?

How many wlan clients are in your network?  Are they 2.4ghz or 5 ghz?

[along5664]

Right now I am testing with just one client, and I have tried boht 2.4ghz and 5.0 ghz, does not seem to mater which one, I get the same results. Download is slow and upload is what I expect to be normal. Upload is about 3x faster....

Is the wireless client on the same layer 2 sub net as your wired clients?

[along5664]

Yes ,the ap is on the same vlan as my wired client. Wired client works just fine.

Are you dropping broadcast/multicast?

[along5664]

I am not aware of any dropping of broadcast/multicast.

[zjennings]

I would drop broadcast/multicast on the wireless (and enable convert arp requests to unicast). Then try your speedtests again.

[along5664]

Still running the same results. Uploads are still 2-3x faster...

Check the TX power on the AP. I've seen this before, but I can't remember what caused it.

Also, do a show ap debug radio-stats ap-name someAP radio 0 advanced | include Busy

Run that on radio 1 as well.
