Consolidated Communications Illinois FAQ
Is Fidium Fiber available at my Illinois address?
Fidium Fiber availability in Illinois depends on whether Consolidated Communications has completed fiber construction in your specific neighborhood. The company serves Mattoon, Charleston, and central Illinois communities, but availability varies block by block. Check the company's online availability tool with your street address to confirm whether fiber or DSL service is currently offered at your location.
What is the difference between Fidium Fiber and Consolidated Communications DSL?
Fidium Fiber is Consolidated Communications' modern fiber-optic internet service, delivering symmetrical speeds up to 2 Gbps. DSL uses older copper telephone lines and is limited to 25-50 Mbps download with much lower upload speeds (3-5 Mbps). As Consolidated builds fiber across Illinois, Fidium Fiber is progressively replacing DSL service, offering dramatically better performance at competitive prices.
Does Consolidated Communications require a contract in Illinois?
No, Consolidated Communications does not require long-term contracts for either Fidium Fiber or DSL internet service in Illinois. You can subscribe on a month-to-month basis and cancel at any time without early termination fees. Pricing is straightforward with no promotional rates that increase after an introductory period.
When will Fidium Fiber be available in more Illinois areas?
Consolidated Communications is actively expanding Fidium Fiber across its Illinois service territory, but specific timelines vary by community. The company prioritizes fiber construction based on engineering feasibility, existing infrastructure, and community demand. As Consolidated's headquarters state, Illinois typically sees new Fidium Fiber expansion and service improvements rolled out early compared to other markets. Residents in DSL-only areas should check back periodically, as the company regularly announces new Fidium Fiber expansion areas.
Does Fidium Fiber have data caps in Illinois?
No, Fidium Fiber plans from Consolidated Communications do not have data caps in Illinois. Subscribers can use their internet connection without worrying about monthly usage limits, overage charges, or speed throttling based on consumption. This unlimited data policy applies to all Fidium Fiber tiers from the 50 Mbps plan through the 2 Gig plan.
Consolidated Communications Fiber Upgrade Program
Consolidated Communications has committed to a major fiber optic expansion across its service territory, converting legacy copper DSL infrastructure to fiber-to-the-home technology. The company's fiber network delivers symmetrical speeds up to 1 Gbps with no data caps, and premium tiers up to 2 Gbps are available in select markets. This upgrade program represents one of the largest rural and suburban fiber deployments in the northeastern and central United States.
For customers in areas not yet upgraded to fiber, Consolidated offers DSL service with speeds up to 25-100 Mbps depending on distance from the central office. The company publishes community-level upgrade schedules on its website, allowing current DSL customers to track when fiber will become available at their address. All fiber plans include professional installation with an indoor WiFi 6 router, managed WiFi coverage throughout the home, and 24/7 technical support.
Tips for Getting the Best Internet Experience
Optimizing your home network starts with proper router placement. Position your WiFi router in a central, elevated location away from walls, metal objects, and electronic devices that create interference. A router placed in an open area on a shelf or mounted on a wall can improve WiFi coverage by 30-50% compared to one hidden in a closet or behind furniture. For homes larger than 2,000 square feet or with multiple floors, consider a mesh WiFi system with satellite nodes placed in each area where you need strong coverage.
Regular maintenance keeps your connection performing at its best. Restart your modem and router monthly to clear cached data and refresh your connection. Check for and install firmware updates quarterly, as these often include performance improvements and security patches. Monitor your actual speeds using periodic speed tests, and contact your provider if wired connection speeds consistently fall below 70% of your plan speed during off-peak hours. Most providers will troubleshoot remotely first and schedule a technician visit if the issue requires on-site diagnosis.
