Jake: Since AES is a higher level of encryption it makes sense that it will require more processing and result in a performance hit versus TKIP. In my mind a more significant issue here is that 802.11n will only support AES as TKIP was deprecated in the n standard.
Colin Daniel Senior Network Analyst Montana State University From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] On Behalf Of Barros, Jacob Sent: 2013-01-24 10:44 To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: [WIRELESS-LAN] need help to substantiate an SSID recommendation I feel silly asking this question but value your opinions. We recently had some authentication errors that caused me to open a support case. The engineer I was working with eluded to the fact that having a space in my SSID name could be contributing to the problem though not the root. He also inferred that using TKIP instead of AES would cut processing requirements on the controller and therefore grant better performance. I have not been able to confirm his opinions from those I have asked (including other engineers from the same company) nor in print. We are using a single SSID for most of our campus, 'Grace WiFi' WPA2-PSK AES. Theoretically, should I get better performance (or less overhead) from 'Grace-WiFi' WPA2-PSK TKIP? Leaving the vendor/company out of this conversation, will you please comment on whether or not these changes will make a difference? I would love to either substantiate or debunk this theory.
