After a slow start in the red zone, the Green Bay Packers picked up the pace in the second half to overpower their offensively-challenged NFC North rivals.
"A lot of moving parts, a very satisfying victory at home," coach Mike McCarthy said.
The Packers (4-2) moved effectively on short gains most of the night, but couldn't break into the end zone until Adams caught the first of his two touchdown receptions with 9:11 left in the third quarter for a 13-10 lead.
Rodgers and Adams combined again for a 4-yard score on the first play of fourth quarter for a 10-point lead.
An offense that was already 31st in the league in scoring got worse. Barkley was 6 of 15 for 81 yards and two interceptions.
"Well, when you lose your starting quarterback it can be disruptive," Bears coach John Fox said. "It's not an excuse, it's just a reality."
He tried to lean on the rush against the NFL's third-best run defense. It didn't work either.
Adams, Montgomery and Cobb each finished with at least 10 receptions.
