Andrew Shinnie opened the scoring four minutes before the half-time whistle as he bent a lovely strike into the bottom left corner from 20 yards, before Harry Cornick secured the result with a tidy finish after 72 minutes.Town will be ball number 35 in the second-round draw, which takes place at 7pm on BBC2 on Monday evening.
Jones said: "It's never comfortable when you play against Wycombe because they are a full-on side that get after you and make it difficult for you and so on. I thought it was a thoroughly professional performance, I wouldn't say comfortable, but I'd say we were very professional.
"Both sides were missing big players, I think they had one or two out, we had two or three out to be fair, so we knew it was going to be a tough game. we knew that, they always are against Wycombe, but once we go the first goal, I felt the game was in our favour, Wycombe sort of petered out then and then it was our game.
"It's difficult to create a tempo against them sometimes and if they get in front it's even worse. We had to generate all the pace and the tempo. So we knew it was important to get the first goal, we should have been further ahead because we scored a perfectly good goal, James Collins is well onside, so that's a disappointing one. He's onside, it's a great finish, so we should have been 2-0 up at half-time.
"The second half followed the same pattern, we had a couple of chances and then we capitalised on an error. So I am very pleased with the performance and we are obviously going through to the next round."
