WOW!'s Illinois coverage is centered on the Chicago suburban market. The provider serves communities west, northwest, and southwest of the city, offering a contract-free cable internet alternative in an area dominated by Comcast Xfinity and AT&T. For suburban households looking to avoid data caps and long-term commitments, WOW! fills an important gap in the Illinois broadband landscape.
WOW! Internet Plans Available in Illinois
Illinois residents in WOW!'s footprint have access to the provider's standard plan lineup. Every plan includes unlimited data, no annual contracts, and an included modem.
| Plan | Download Speed | Upload Speed | Monthly Price | Contract | Data Cap |
|---|---|---|---|---|---|
| Internet 200 | 200 Mbps | 10 Mbps | $40/mo | None | Unlimited |
| Internet 500 | 500 Mbps | 50 Mbps | $60/mo | None | Unlimited |
| Internet 1G | 1,000 Mbps | 50 Mbps | $80/mo | None | Unlimited |
The 200 Mbps plan is well-suited for small households. Families with multiple devices streaming simultaneously will benefit from the 500 Mbps or 1 Gbps tiers. All plans use WOW!'s cable (DOCSIS 3.1) network in Illinois, with fiber availability still limited in the state.
WOW! Coverage in Illinois
WOW!'s Illinois service area is concentrated in the western and northwestern suburbs of Chicago. The provider does not serve the city of Chicago itself, nor does it cover downstate Illinois. This suburban focus means that WOW! competes primarily in communities where Comcast Xfinity has traditionally been the default cable option.
The coverage footprint extends through parts of DuPage County, Kane County, and Will County. Some communities at the edges of the footprint may have partial coverage, meaning that service is available on some streets but not others. Address-level verification is essential.
Illinois Cities Served by WOW!
WOW! provides internet service in the following Illinois communities. Coverage depth varies:
- Naperville — One of WOW!'s strongest Illinois markets with extensive coverage
- Aurora — Kane County's largest city with WOW! availability
- Schaumburg — Northwest suburb with WOW! service
- Bolingbrook — Will County suburb served by WOW!
- Downers Grove — DuPage County community with coverage
- Wheaton — DuPage County seat with WOW! presence
- Carol Stream — Suburban community with availability
- Glen Ellyn — DuPage County village served by WOW!
- Lisle — Near Naperville with WOW! coverage
- Woodridge — Suburban community with service
- Plainfield — Growing suburb with partial WOW! coverage
- Lombard — DuPage County village with availability
Many of these communities are among the most populated suburbs in the Chicago metropolitan area, giving WOW! access to a large potential subscriber base despite its relatively concentrated geographic footprint.
How WOW! Compares to Other Illinois Providers
The Chicago suburban broadband market is competitive, with several providers vying for customers:
- Comcast Xfinity — The incumbent cable provider across Chicagoland. Xfinity offers higher maximum speeds and broader coverage but imposes a 1.2 TB data cap and typically requires promotional commitments. WOW!'s unlimited data and contract-free approach are strong differentiators for data-heavy households.
- AT&T Fiber — Expanding aggressively in the Chicago suburbs. Where AT&T Fiber is available, it offers symmetric speeds that outperform WOW!'s cable upload performance. AT&T Fiber pricing is competitive, but availability is not yet universal in the suburbs.
- T-Mobile 5G Home Internet — Available as a fixed wireless alternative at $50/mo. Performance varies by tower distance and network congestion. WOW!'s wired connection generally provides more reliable speeds, particularly during peak usage hours.
In the Chicago suburbs, WOW! stands out for households that want predictable pricing, no data caps, and the freedom to cancel at any time. The trade-off is a narrower service area compared to Xfinity or AT&T.
WOW! Performance and Reliability in Illinois
WOW! delivers its Illinois service over a DOCSIS 3.1 cable network, which provides strong download speeds but asymmetric upload performance. In real-world testing across Chicago suburban markets, WOW! consistently delivers 85-95% of advertised download speeds during non-peak hours and 75-85% during peak evening hours (7-11 PM).
Upload speeds are the biggest limitation. The 10 Mbps upload on the base 200 Mbps plan is adequate for basic video calls and cloud backups but may bottleneck for households with multiple people in simultaneous video conferences. The 50 Mbps upload on the 500 Mbps and 1 Gbps plans provides more breathing room for remote work and content creation.
Latency typically ranges from 10-25ms, which is sufficient for online gaming, video conferencing, and real-time applications. WOW! reports 99.9% network uptime across its Illinois markets, though localized outages can occur during severe weather or construction activity near network infrastructure.
WOW!'s DOCSIS 3.1 infrastructure supports Low Latency DOCSIS (LLD) in some Illinois markets, which can reduce latency further for compatible devices. This technology is particularly beneficial for competitive gaming and VoIP applications.
Installation and Equipment
WOW! offers both professional installation and self-install options for Illinois customers. Professional installation costs $50-$75 depending on the complexity of the setup, though WOW! frequently waives this fee during promotional periods.
Self-installation kits include a DOCSIS 3.1 modem and coaxial cable. The process typically takes 20-30 minutes: connect the modem to the coaxial outlet, power it on, and activate through WOW!'s online portal or by calling customer service. Self-install works best in homes with existing coaxial wiring in good condition.
WOW! includes a standard modem at no additional cost with all Illinois plans. However, the included device does not include Wi-Fi routing capability on all plan tiers. Customers who need Wi-Fi can either rent a WOW!-provided router for $5/mo or use their own router. Using your own router saves $60/year and often provides better performance.
For larger Illinois homes, WOW! offers a whole-home mesh Wi-Fi add-on for $10/mo that includes 2-3 mesh nodes. This is competitive with purchasing your own mesh system, especially for customers who prefer the simplicity of a single support contact for all networking equipment.
Customer Service and Support
WOW! differentiates itself from larger Illinois providers through its customer service approach. The company has earned consistently higher customer satisfaction scores than Comcast Xfinity in regional surveys, with a 2025 ACSI score of 66/100 compared to Xfinity's 59/100 in the Midwest region.
Illinois customers can reach WOW! support through:
- Phone support: Available 7 AM - midnight ET, 7 days a week
- Online chat: Available during the same hours with typical wait times of 2-5 minutes
- WOW! app: Self-service tools for bill pay, speed tests, and troubleshooting
- Local offices: WOW! maintains retail locations in select Illinois markets for in-person support and equipment exchanges
Common complaints in Illinois center on price increases after promotional periods and occasional service interruptions during network upgrades. WOW!'s no-contract policy means customers can switch providers without penalty if service quality declines.
Is WOW! Worth It in Illinois?
WOW! occupies an important niche in the Illinois broadband market. For Chicago-area suburban residents who have access to WOW!, the provider offers several tangible advantages over the dominant competitor (Comcast Xfinity):
- No data caps: Unlike Xfinity's 1.2 TB monthly cap, WOW! offers truly unlimited data on every plan
- No contracts: Month-to-month service with no early termination penalties
- Lower entry price: $40/mo for 200 Mbps undercuts Xfinity's comparable offering by $15-20/mo in most Illinois markets
- Better customer service: Consistently higher satisfaction scores than Xfinity
The main drawbacks are limited coverage (Chicago suburbs only), asymmetric speeds typical of cable, and the lack of fiber service in Illinois. Households needing symmetric upload speeds for heavy remote work should consider AT&T Fiber in Illinois where available.
Frequently Asked Questions About WOW! in Illinois
Is WOW! available in Chicago?
No. WOW! does not serve the city of Chicago. Its Illinois coverage is limited to suburban communities west and northwest of the city, including Naperville, Aurora, Schaumburg, and Bolingbrook. Residents within Chicago city limits should consider Xfinity, AT&T, or RCN as alternatives.

Does WOW! offer fiber in Illinois?
WOW!'s Illinois network primarily relies on cable (DOCSIS 3.1) technology. Fiber-to-the-home availability in Illinois is limited compared to WOW!'s Ohio and Michigan markets. The company may expand fiber in Illinois in the future, but current subscribers should expect cable-delivered service.

Is WOW! better than Xfinity in the Chicago suburbs?
WOW! offers several advantages over Xfinity: no data caps, no contracts, and generally lower prices for comparable speeds. Xfinity has broader coverage and faster top-tier speeds.

How WOW! Technology Works in Illinois
WOW! uses cable (docsis 3.1), fiber technology to deliver internet service in select Illinois communities. Fiber-to-the-home is the fastest and most reliable broadband technology available, using thin glass strands to transmit data as pulses of light.
Fiber Internet Technology Explained
Fiber internet delivers data through fiber-optic cables that run directly to your home. Unlike cable or DSL, which use copper wires, fiber optics transmit data as light pulses, enabling symmetrical upload and download speeds. For Illinois residents in WOW!-served areas, this means upload speeds match download speeds, which is ideal for video conferencing, cloud backups, and content creation.
WOW! builds its fiber networks from the ground up in partner communities. In Illinois, this community-first approach means that where WOW! is available, every connected home receives a dedicated fiber line with no shared bandwidth. The result is consistent performance regardless of how many neighbors are online simultaneously.
Performance Expectations in Illinois
WOW! delivers symmetrical speeds up to 1 Gbps. Because fiber networks do not share bandwidth at the neighborhood level, Illinois customers can expect consistent speeds throughout the day, including during peak evening hours. Fiber connections also have very low latency (typically 1-5 milliseconds), making them excellent for gaming, video calls, and any latency-sensitive application.

Internet 500 Plan — Best for Growing Households
The Internet 500 plan at $60/mo offers a balanced combination of speed (500 Mbps) and value. This mid-tier option works well for Illinois households with 3-5 people who stream regularly, work from home occasionally, and use multiple connected devices.
