I have some 871W. Is it possible to make wireless network open (no authentication, available for all) but with encryption ?
I've read somewhere i could do something like this using 802.1x, but could not find any cisco documentation for that.
I want to be sure that everybody can use wireless but the sniffing is not possible (or very difficult).
Is it possible ? If yes could you give me link to documentation ?
Understood... but that is why the minimum protection is up to you to decide. Again... with guest wireless, you can't force any type of encryption or else you will be supporting the users. No matter what vendor you use, the outcome will be the same. Encryption and Authentication is there for one to use if configured. If you had a wired guest, how would you protect him or her?
