wireless encryption question

[fivealive]

so i have my wireless turned on so that i can access the internet on my phone and on my laptop. well anyway the modem restarted today (called isp turns out it was a firmware update) with out warning and when it came back online i logged into the modem and noticed my wireless settings looked weird and i was wondering if someone could explain a few things namely:

what does it mean by saying that the encryption length and default key is none when i have a password on the wireless (wireless is also hidden so its not broadcasting so that people can see it. also of note for some reason it says the encryption type is wpa when its wpa2 personal)
