Got it working. Here are some things I did. I am sure some of these are unnecessary holes to leave open, but its working. These settings can be removed one at time to narrow down exactly what is required to have set.
Windows 7 64bit Brother MFC-J615W Network Scan to Setup
1. opened UDP ports 137, 54925 & 54926 in windows firewall
2. set write/read permissions for guests and users
4. In CC3 the configuration of the SCAN TO has two tabs; one for device and one for software. You need to pay attention to the directory/s that you want use.
I am now very satisfied with this printer. It is my first Brother and I don't think the last at first impression. I now have this printer working wireless with a Ubuntu Netbook Remix, a MacBook 10.5 OS and Windows 7 64bit.
