We've got two SSID's - "Rice Visitor" and "Rice Owls". The 802.1x is,
obviously, "Rice Owls". It allows WPA/TKIP and WPA2/AES. There is a space
in each SSID name, and we've had no reported issues with that, nor have we
been told of any issues, including results from a WLAN survey via advanced
services. The TKIP vs AES makes sense (higher encryption standards would
make for more CPU usage), but TKIP is 'broken', meaning that it is cracked.
It's available only for some of the legacy devices that do not seem to be
able to do WPA2/AES.

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.
