- Data caps and throttling — Some providers in Buffalo Grove impose monthly data limits. If your household regularly exceeds 1 TB per month, look for plans with unlimited data or generous caps.

- Equipment fees — Router and modem rental fees can add $10-15 per month. Purchasing your own compatible equipment often pays for itself within a year.
- Customer service reputation — Read local reviews from other Buffalo Grove residents. A provider with excellent speeds but poor customer support may not be worth the savings.
