Has anyone made the move from WPA1/TKIP-only to WPA2/AES-only in the WLAN?
Did you find a significant (or insignificant) percentage of client
devices that couldn't make the change? Did you make any attempts to
otherwise accommodate the user devices that couldn't make the jump? Any
other details of the transition worth mentioning?
Hi Lee,
We have nearly completed this (we have a second SSID that is still
WPA/TKIP, but that will be turned off in July. It has very few users.)
* XP SP2 will need SP3 or hotfix KB917021
* Many laptops ship with very old wireless drivers. Many of these proved to
be unstable or not support WPA2, so our helpdesk have local copies or
direct links to all the common drivers.
* We don't sell kit direct to users, but we keep a list of cheap and
cheerful USB wireless adapters if a laptops lack of WPA2 can not be fixed
with a driver update.
* For the smaller mobile devices, we haven't had problems - All that
support 802.1x, tended to support WPA2 as well.
* Ubuntu / Mac OS / Blackberry / iPhone can auto detect the change from
WPA/TKIP to WPA2/AES and just work (with the same SSID name), but Vista and
Win 7 can't. ...I can see the advantages of being able to enforce WPA2/AES
client side though.
Regards,
James
