Hi, I wasn't a part of the v7 wireless beta so I am not really sure if this was covered already. I did a quick search but didn't get any relevant posts.
When setting up wireless security, the pass-phrase is checked for minimum length but the error message is really vague and doesn't give any hint of what the problem is. Moreover, I didn't see any mention of minimum password lengths on the initial setup screen. I realize that it probably would be included in the help file but who reads a help file right[;)]
Another thing that may be considered is a separate setting under password complexity that would be relevant to wireless security? Just a thought.
Screenshot: Add a wireless password shorter than 8 characters and you will get the error message shown in screenshot.
