Owls fans are desperate for some pre-Christmas cheer, with former Newcastle owner Mike Ashley among those bidding to bring the club out of administration.
Ipswich nearly gifted Wednesday the lead when Dara O’Shea was robbed by Jamal Lowe and his shot was cleared off the line by Kipre.
The home supporters were not happy and their mood nearly worsened when Liam Palmer lobbed the ball just over the bar from Christian Walton’s poor throw-out.
Ipswich rallied and Marcelino Nunez headed just wide after Wednesday goalkeeper Pierce Charles saved Jens Cajuste’s shot and Philogene saw a scissors kick hit the post.
The Tractor Boys made the breakthrough on 33 minutes when Kipre rose to head home Leif Davis’ corner from close range to the relief of the home crowd.
Ivan Azon, who replaced the injured George Hirst early on, glanced a header wide before Philogene made it 2-0 on the hour.
Cajuste drove from deep and found Nunez, who slipped the ball to Philogene at the near post and he scored his eighth goal of the season, all at Portman Road.
To their credit, Wednesday kept going and Cooper rifled home when Ipswich failed to clear Barry Bannan’s free-kick.
But Ipswich bagged their third three minutes from time when Azor Matusiwa intercepted the ball and Clarke applied the finish.
It might have been four, only for Charles and Gabriel Otegbayo combined to deny Azon in the sixth minute of stoppage time.
