Enabling TKIP in a 2504 controller decreases to half of throughput using AES

[a.azambuja]

Hello Guys,

I´m in an environment where using WPA+WPA2 / AES I reach the same trhoughput without security, Aprox 12Mb. But, when TKIP is enabled, this throughput  decrease to 5Mb. Is it normal or is a controller CPU processor intensive that decrease the throughput? 

I tested web auth also and can reach 12Mb. Just with TKIP enabled this problem occur.

Tks.

Hi

Here are the rules for get high throughput or 802.11n data rates on your WLAN

1. WMM should be enabled (WLAN QoS tab -> WMM should be "allow" or "required")
2. Layer 2 security should be either WPA2/AES or Open (WLAN Security tab -> L2 Security)

Unless you comply with above, you won't get any 802.11n data rates(High Througput). As you said above, if you use TKIP then your throughput degradation is expected.
