How we review internet in Illinois
When reviewing internet providers in Illinois, we didn’t just focus on the fastest speeds in major cities like Chicago. We considered Illinois’ diversity, from rural agricultural areas to the shores of Lake Michigan, to methodically evaluate ISPs across the state. So, no matter where you live, you’re getting a fair, expert-backed and well-rounded view of the best internet providers available near you.
Our methodology
We evaluate broadband providers in four categories: affordability, performance, value and customer satisfaction. Each category contains multiple sub-factors, all of which are weighted differently to impact the provider’s overall score.
For each sub-factor, we score all providers on a continuous scale of one to five, relative to the industry as a whole. Because the average download speed in America is currently 290 Mbps, for example, we assigned all plans with download speeds between 100 and 299 Mbps a score between three and four. Xfinity’s 200 Mbps plan received a 3.50 score for download speed, while Spectrum’s 500 Mbps plan got a 3.71.
We only considered standardized data points in our scoring system. More abstract data like consistency of service and brand reputation is still part of our analysis, but we opted to let our writers address them in the context of each review.
