Hi,
I,m currently using wep. A lot of my devices have as well as wep, wpa and wpa2 which I think would be more secure.

The linksys doesn't match with those options though, it has wpa professinal and enterpirise, only my ipad has enterprise. Others including tivo just have wpa, and wpa2 without any following words.

Is wpa professinal the same as wpa? Or do I need to upgrade firmware, bit scared doing this as other then encryption format router doing everything I want it to do.
