Wiggins enjoyed highly successful loan spells at Dean Court before making the switch permanently from Norwich City during the summer.
Boss Eddie Howe sealed a one-month deal for Tottenham Hotspur right-back Smith earlier this week and the 19-year-old is set to make his debut when Cherries host Carlisle today (3pm).
And Wiggins, who helped Cherries avoid relegation and then win promotion during his loan stints in Dorset, believes the welcoming environment at the club will have helped Smith settle in.
The left-back told the Echo: You don't really know how to take people when you first come in.
But fortunately for me, and for Adam as well, we've got a good bunch of lads here and they make you feel welcome straight away, so settling in is not a problem.
All the players are open to new players coming in and it's just going to help the team.
Wiggins admits new players will always be keen to make a big impact but he believes the key this afternoon is to help Cherries remain solid defensively and keep a clean sheet.
Asked what advice he would give to the club's latest acquisition, he said: He's got to play his own game.
He knows the team shape and we do a lot of it in the week, so as long as he sticks to that, I'm sure he'll be fine.
You always want to make an impression but the way to do it in defence is to keep solid and keep a clean sheet.
We're not asking major things we don't expect him to go forward and score a hat-trick so as long as he puts in a shift, I'm sure we'll be happy with him and so will the fans.
He's been on loan twice before with Wycombe and Torquay so he knows what the league is about.
Wiggins scored for the second consecutive game when he netted a fine free-kick in the defeat at Oldham Athletic last weekend, following on from the first league goal of his career in a sparkling individual performance against Dagenham and Redbridge.
He added: It was nice to get the second one so I'll be pushing forward today trying to make it three in three.
