THE Linnets failed to find the back of the net for the first time this season as they slumped to their first home defeat since the opening day of the campaign.
Defensive errors cost Lynn dearly as an organised Nantwich outfit stormed to the top of the league standings.
Ashley Carter pounced on some dreadful indecision between Lynn goalkeeper Danny Gay and Lathanial Rowe-Turner to fire Town ahead before the break.
Nantwich target man Matt Read then bagged two goals inside three minutes inside the first 15 minutes of the second period as Lynn caved in almost at will.
Linnets boss Carl Heggs said: "I'm absolutely gutted and so disappointed. We've all worked hard in what has been another difficult week and we've missed a great opportunity to go second in the table.
"We've started quite brightly but then we have given them the worst goal I've been involved in since I've been at the football club.
"You can be the best manager in the world and have all the qualifications and coaching badges possible, but you can't coach that.
"I've brought myself on and in all fairness I probably should have started myself, but we've just crumbled, which disappoints me.
"We allowed their number nine, who was two stone overweight and cumbersome, to bully us and he has caused us all kinds of problems."
Lynn bossed the early stages, but there was little to show in attack apart from Carl Palmer's effort which cannoned back off the bar early in the second half.
For the first 20 minutes Lynn looked set to continue where they left off against Hucknall, with Owen Story a constant thorn in the Nantwich side with his pace, while Kwesi Appiah, Lynn's new on-loan signing from Peterborough, and Antony Robinson went close.
The visitors weathered the early Lynn storm and gradually began to find their feet.
In the 35th minute they took the lead when Gay and Rowe-Turner both left the ball for each other and Carter nipped in to head home.
Nantwich totally dominated matters after the break and Lynn escaped a second goal when Mahmood rounded Gay but Bobby Aisien blocked his shot on the line and cleared.
Linnets boss Heggs introduced himself and for a few minutes gave Lynn a much-needed lift.
Palmer struck the Nantwich woodwork from six yards out and soon after Nantwich increased their lead when Read was allowed a simple tap-in.
Three minutes later, Read struck his second with a header from Mahmood's corner after he was left totally unmarked at the far post.
Andy Boyce was on hand with another goal line clearance to deny Rodney Jack as Lynn ran out of ideas without a fight.
