Wanderers made it four points from two games with a second successive clean sheet in a stalemate with Bristol Rovers at the Memorial Stadium.
Fred Onyedinma and Jack Grimmer went closest to breaking the deadlock for the Chairboys in the second period, while Victor Adeboyejo was Rovers' most likely goalscorer, striking the inside of the post before the break, and Liam Sercombe also went close with two free-kicks.
Gareth Ainsworth made one change to the side that defeated Bolton last weekend, with Onyedinma taking the place of Alex Samuel in the front three, while the hosts lined up in a diamond formation with key striker Jonson Clarke-Harris back on the bench following an injury absence.
The Gas lost Mark Little to injury early on, with Josh Hare taking his place, and the game then entered a lull before Adeboyejo and Tom Nichols both forced smart saves from Ryan Allsop with efforts from the edge of the box.
Rovers upped the pressure ahead of the interval, with Sercombe bending a free-kick just wide, seeing another tipped over by Allsop, and Adeboyejo saw a shot bounce off the inside of the post and land wide of the far post with a smartly-taken shot from outside the box.
With the wind now in their advantage in the second period, Wanderers grew stronger as the game went on, with Smyth seeing a near-post shot tipped behind for a corner before Adebayo Akinfenwa fed Onyedinma from the resulting corner, only for home keeper Anssi Jaakkola to spread himself and block the effort.
Alex Samuel and Nick Freeman both came off the bench to inject new life into the frontline, and Samuel blocked a clearance from the keeper with the ball spinning a few yards wide.
As the game moved towards stoppage time, Alex Pattison created a golden chance after beating his man down the left, but Jack Grimmer's low shot was cleared off the line by Tom Davies and there was no more time for late drama as both sides settled for the point.
