Hello everyone,
I'm having a hard time figuring out why we lost half of our wireless speed over g radios after we went lightweight.
We just upgraded from autonomous to lightweight with a 5508 controller on software version 7.0.116.0.
At our venue, before an event we do speed tests at commonly used wireless areas and would get 15Mbs - 20 Mbs to speakeasy. After the upgrade, speeds are cut in half for the g radios (usually it's 7-10Mbs).
The only clients that can get this speed are the clients that are capable of using the A radio. Also, if we connect to a linksys AP (it's a temporary band-aid for a dead AP) we get the 15-20 speeds.
These are all 1131ag AP's. The controller has the default config on the b/g/n radios, the client shows it's connected at 54Mbs. QoS is also default. All SSID's are WPA2-PSK with default everything else.
I've tested the speeds on an AP with 8 users on it, and on an AP where I am the only one on the AP. The network usually only has 12 active associations at a time during the day over our 8 AP's. The most I've ever seen on 1 AP during the day is 10 users.
Anyone have an idea why we lost this speed using the same AP's but we can get the correct speed via the A-radio or another autonomous AP?
Thank you,
Nick
