The home side continued to dominate and captain Mike Blair's cross-field run set up Webster to touch down Edinburgh's third try under the posts, with Paterson adding the extras.
Nene had 20 points and 11 rebounds, Wall added 15 points and nine assists, and Martell Webster scored 16 points for the Wizards, who rolled off a 22-2 run during the Nets' field goal drought, which finally ended on Brook Lopez's inside basket with 3:36 remaining in the half.
