Brian Carey has been appointed Wrexham manager for the rest of the season.
Carey will be assisted by Joey Jones
The ex-Dragons defender and coach took over at the Racecourse after Thursday's shock dismissal of manager Denis Smith.
"Continued speculation about who the club might be appointing is unhelpful to all concerned, especially Brian and the players," said a Wrexham statement.
"Our short-term aim is to ensure the club remains in The Football League. The directors feel Brian Carey is the man to lead us through this period."
Carey, 38, will be assisted by club stalwart Joey Jones until the new boss decides on a permanent candidate for the job.
The former Wrexham captain was given a coaching position by Smith in July 2005 after the Irishman was forced to end his playing career because of injury.
I turned down job offers when we were in administration - maybe I should have taken them
Smith had been Wrexham manager since 2001, winning promotion to League One in 2003 and winning the Football League Trophy in 2005.
He says the club has made a mistake in sacking him and that Wrexham need an experienced hand at the helm.
"The decision was based on the league table and results so I understand it, but I don't think it was a good decision," Smith told BBC Sport Wales.
"I had a player coming to Wrexham to sign on Thursday afternoon and I had to tell him to turn around as I was out of a job, so you could say it was a surprise.
"But that's football. The new people at the club want everything to be rosy and perhaps don't understand that the game isn't always like that.
"I thought things were turning around a few weeks ago, but then Juan Ugarte and Lee McEvilly had injury setbacks and we also lost Mark Jones - those are three important players who get us our goals.
"It's a very good club, it will go on and do well. I wish them all the best and will remember the great time I had in Wales.
"I'll get on with my life, but I do feel that it could have been me turning the club around, I was looking forward to the building work.
With Darren Ferguson touted as a future manager I thought that he would want to be in temporary charge

"It's hard after the difficult times we've been through at the club. I turned down job offers when we were in administration - maybe I should have taken them, but it was my choice and I have no regrets."
Wrexham legend and ex-Dragons manager Dixie McNeil says he was surprised at the timing of the release of Smith and his assistant Kevin Russell, and of the decision for Carey to be caretaker.
"I didn't think they would go after an FA Cup defeat," McNeil told BBC Sport Wales.
"Releasing Kevin as well as Denis means there is no continuity, and with Darren Ferguson touted as a future manager I thought that he would want to be in temporary charge.
"The players will also be surprised, but they can't worry about it.
"It will be interesting to see how they react, but they must get their heads down and work hard."
