WPA or WPA2 a AIR-AP1142N-E-K9 will reduce the speed of Accesspoint down to 54Mbps when associate to PC

[Steve30001]

Why AIR-AP1142N-E-K9  300Mbps to open, but only unsecure.  If I use WPA or WPA2 a AIR-AP1142N-E-K9 will reduce the speed of Accesspoint down to 54Mbps when associate to PC

N Speeds are supported only when we configure "OPEN AUTH with WMM Enabled + All MCS Rates enabled" OR WPA 2 WITH WMM Enabled + All MCS rates enabled"

Just the WPA will not support N speeds.. Use WPA 2..

lemme know if this answered ur question!!

If it was a so.

Please tell me. where I can find document references ? .

and config for AP speed drop when used WPA or WPA2

see config in attached file

PS. I used standalone Accesspoint , not have controller

[Surendra BG]

Either Its Controller based or autonomous, the soulution remains the same.. Wither Open or WPA2 only supports N speeds .. WPA alone will not..

here is the configuration guide that tells the same..

Search for 802.11n (First hit will answer ur concern).

Lemme know if this answered ur question and please dont forget to rate the useful posts!!

Please Google search for "802.11 N + WPA + N speeds + Cisco" you will get more documents..

I'll just add that it's "WPA2 with aes" supporting 11n speed. If you have WPA2/tkip, you will only get 54Mbps, which probably explains what you saw.
