So after looking at all of this and looking at you NAT pieces and ACL's, my question would be to you and Jester that I feel the Wireless security level should be lets say 95. My reasoning is that there is no way(that I know of) to force internet traffic over the lease line easily(the acl's will get really messy). So let the device fall back to allowing higher level traffic flow to lover level. Seeing the wired is a rating of 100 it can flow across the leased but the wireless can not because it is lower.
That's my suggestion to try.
Good Luck,
