Match ends, Wrexham 3, Alfreton Town 1.
Andy Bishop scored twice as Wrexham avenged last season's FA Cup defeat by Alfreton to advance to the second round.
Bishop gave his side the lead with a header from Neil Ashton's cross before adding a second after good play by Brett Ormerod.
Ex-Wrexham striker Jake Speight scored from the spot after Stephen Wright's foul on John Akinde.
Jay Harris settled nerves with a volley after Ross Atkins saved Ormerod's shot.
Kick-off at the Racecourse was delayed for 20 minutes after the Alfreton team bus was held up in traffic.
VIEWS FROM THE DRESSING ROOM
Wrexham player-manager Andy Morrell told BBC Radio Wales:
"I thought we were good today - it's been the best we've been for quite a while and it starts from the start.
"We start the game right, keep the ball right, nullify their threats and when we keep the ball and pass and move we're a half decent team.
"I thought we thoroughly deserved it today."
