Cribz chief executive Peter Esho says his company crunched the numbers on how many houses were connected or to be connected in any given suburb to get a final ranking.
"What we did was look at the fibre rollout and availability. Different blocks and streets and houses will have different results," he says.
"Brisbane's a really interesting city because it's very patchy in terms of fibre and NBN rollout."
Having the NBN or fibre connection isn't a guarantee of a great internet connection, but as ADSL and cable connections age, the next-generation infrastructure will become vital to new homeowners.
"It's become one of the most important utilities. Not only does it give you the ability to work from home, but entertainment like Netflix or Spotify, the amount of time that you spend using it ... The home is changing," Mr Esho says. "If you don't have strong internet it can affect your quality of life."
The best areas for next-generation connectivity were North Lakes, Narangba, Kallangur and Strathpine, Mr Esho says.
Some of the worst were Herston, Salisbury, and Waterford.
"The city fringe is quite patchy," he says.

"We built entirely in the Messenger app," Mr Esho says. "We said, what's the point of building our own app, because people won't download an app unless they're great utility, like Uber."
Well-connected suburbs were prioritised because Mr Esho's team found their target demographic was interested in tech-readiness, as well as suburbs with the most fitness facilities, and walkable suburbs.
"We actually sat back and said, 'For millennials, what are the things that matter?' We put out some content and found out what performed best. We saw a huge reaction. We're saying, 'Here's a bunch of things, what's interesting to you?' "
@Realty agent Gary Hassett is based in the fringe suburb of Wakerley, and says the metric is useful but won't affect the habits of the bulk of buyers at this point.
"I can see how it does put people off. Very rarely do we have people asking us about the quality of the internet; going forward it would potentially become an issue," he says.
Mr Hassett says first home buyers are the most concerned about internet speed and reliability, and the current property market is made up mostly of families with young children, or downsizers.
"I would say they're more the driving force," he says. "I honestly think the most important factors are the quality schools."
