His side go into the final six games of the campaign, starting at home to promotion-chasing Hull City, eight points above the drop zone.
Town are still seeking a victory over a team currently in the top eight, and are eager to achieve it against the fourth-placed Tigers after successive losses against Sheffield Wednesday, who are fifth, and Middlesbrough, second.
Four of the other five fixtures are against sides in the bottom half of the table - away to Blackburn Rovers, Rotherham United and Bristol City and at home to Brentford - while Town will seek a double when they host Birmingham City, who are ninth.
“When I came here (in November) the chairman gave me two urgent targets - to bring a new identity to the club and keep us in he division,” said Wagner.
“I think we are on the way in both.
“With six games to go, I think an eight-point gap is okay, but of course we want it to get bigger.
“We want more points and we want them sooner rather than later, starting against Hull.
“This is our last chance to get three points against a side at the top end of the table, and we want to use it.
“We know we have to perform to our maximum, or maybe even overperform, to succeed against them.
“There were too many sloppy mistakes against Middlesbrough.
“We must make it much harder for Hull than for Middlesbrough.
“We have looked at what we did wrong, why we did those things wrong and how we change those things.”
Wagner is confident defender Joel Lynch and forward Harry Bunn will overcome minor niggles while midfielders Jonathan Hogg and Kyle Dempsey are both due to step up their returns from knee and calf injuries respectively from Monday onwards.
