effects of enabling wpa
Configuration
We tested the new
NL-5354AP1 with support for 802.11 super A/G or Turbo mode. We used a nl-5354cb plus card in a HP ze4500 AMD Athlon XP-M 2200 on Microsoft Windows XP SP1 on hard power with power profile set to always on (full CPU speed). For super A testing smart select was used and it picked channel 50. We did not have any other 802.11a access points running at the time.Results super a with WPA enabled AES PSK

Conclusion
Enabling WPA places a small throughput loss of around 1mbps. This is a similar number to our previous testing with WEP. However even though AES is mostly done in hardware it does place an additional 10% load on the CPU on the client computer. It is our opinion that the security WPA provides is well worth the small performance degradation.
