We're looking at the same thing. The only problem, is the native Windows XP supplicant does not support WPA2/AES. XP SP3 adds this compatibility. So, for now, we have added a new SSID which is not broadcast and is WPA2/AES. We are manually setting up clients to connect to that to test N and A/B/G interoperability. So far, things seem to be working well. I expect to leave our configuration in this mode for at least another year, then we'll flip/flop the SSIDs for the WPA2/AES is broadcast and the WPA/TKIP is not. Then after another year, I expect to phase out the WPA/TKIP SSID completely.

So yes, an N client can connect to an N AP with WPA/TKIP or WPA2/AES, but the max data rate will be different (54 vs. 300). Based on this, we plan to migrate to WPA2/AES on our current a/b/g network to prepare for the mixed environment we will have next school year. We plan to deploy 802.11n in a new building that opens next school year and maybe in one or two other buildings, but the majority of our buildings (including all dorms) will be a/b/g.

Hay Network Engineer Computer Services Cedarville University www.cedarville.edu <http://www.cedarville.edu/> >>> Keith Moores <[EMAIL PROTECTED]> 3/16/2008 4:04 PM >>> Just wondering what encryption type those of you that have started moving to (testing with) 802.11n APs are using? I'm trying to confirm that N clients connecting to N APs must use WPA2/ AES to connect with encryption. If an N AP accepts both WPA/TKIP and WPA2/AES can an N client connect set to either albeit only at 802.11n HT rates when using WPA2/AES? -Keith ------------------------------------------------------------------------ Keith Moores <mailto:[EMAIL PROTECTED]> Network S! ystems Senior Engineer ITC-Communications and Systems Division University of Virginia, ITC-2015 Ivy Rd Phone (434) 924-0621 Box 400324, Charlottesville, VA 22904-4324 Fax (434) 982-4715 ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/. <http://www.educause.edu/groups/> ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
