Internet Availability by Denver Neighborhood
Why Denver Has Excellent Internet Options
Denver is one of the fastest-growing tech hubs outside Silicon Valley, with over $23 billion in startup funding. The Colorado Technology Association reports focus on cybersecurity, AI, and sustainable tech sectors. This tech hub status has attracted multiple fiber and 5G providers competing for customers, driving prices down and service quality up.
Colorado Broadband Investment
Colorado received $420.6 million in federal BEAD funding in December 2025, connecting over 96,000 locations. The state goal is 99% broadband coverage by the end of 2027. Google Fiber is also expanding in Denver suburbs, further increasing competition and options for residents.
Neighborhood Coverage Guide
LoDo (Lower Downtown)
Excellent coverage - Downtown's historic district has multiple fiber and cable options. Some small Xfinity gaps near Stout St/15th.
Capitol Hill
Densest neighborhood - Good coverage overall, but older Victorian buildings may have limited internal wiring options. Check address carefully.
Highlands / LoHi
Strong fiber penetration - Trendy area with Quantum Fiber widely available. Newer construction typically fiber-ready.
RiNo (River North Art District)
Tech worker favorite - Creative district popular with startups. Multiple coworking spaces with high-speed options. Strong fiber availability.
Cherry Creek
Upscale area - Excellent fiber and cable coverage from all major providers.
East Denver
Mixed coverage - Check specific address as availability varies significantly by block.
Southwest Denver
Good Xfinity coverage - Quantum Fiber expanding. Some areas still DSL-only.
Why Availability Varies in Denver
Denver's rapid growth means internet infrastructure is constantly expanding. Newer developments in RiNo and Highland are typically wired for fiber from the start, while older Capitol Hill buildings may still rely on cable or have limited internal wiring. Denver's altitude and weather can also affect wireless signals - fiber connections are generally more reliable during severe weather and extreme temperature variations.
Apartment Residents: Check Before You Sign
Many Denver high-rise apartments have exclusive provider agreements. Capitol Hill has the highest concentration of rentals - always verify internet options before signing a lease. Coworking spaces throughout Denver offer backup with high-speed connections if your building has limited options.
Mountain Community Options
Mountain communities near Denver (Evergreen, Conifer, Idaho Springs) have limited wired options. Starlink satellite provides 50-250 Mbps with 25-60ms latency and is the best option for remote mountain homes. Fixed wireless from local providers may also be available in some foothills areas.

How much does internet cost in Denver?
Internet prices in Denver range from $25/month for Xfinity's basic 200 Mbps plan to $165/month for Quantum Fiber's 8 Gbps service. Most Denver households pay between $50-80/month for speeds from 300 Mbps to 1 Gbps.

What internet speed do I need in Denver?
For most Denver households, 300-500 Mbps is sufficient for streaming, remote work, and multiple devices. Work-from-home professionals in Denver's thriving tech sector may prefer 500 Mbps to 1 Gbps for video conferencing and large file uploads. Competitive gamers and content creators benefit from fiber's symmetrical speeds and low latency.
Is T-Mobile Home Internet good in Denver?
T-Mobile 5G Home Internet performs well in Denver, offering 133-500 Mbps speeds with the highest customer satisfaction ratings of any provider nationwide. It's particularly good for renters who move frequently and those avoiding contracts. However, speeds vary by proximity to 5G towers, and it's not ideal for competitive gaming due to higher latency (25-50ms).
What is the cheapest internet in Denver?
The cheapest wired option is Xfinity's Connect More plan at $25/month for 200 Mbps, though prices may increase after the promotional period. Verizon 5G Home starts at $35/month with Verizon mobile discounts. EarthLink offers fiber starting at $39.95/month for 100 Mbps symmetrical. Spectrum has plans from $30/month where available.
Is Xfinity or Quantum Fiber better in Denver?
Quantum Fiber is better for those who can get it, offering faster symmetrical speeds (up to 8 Gbps), no data caps, and a Price for Life guarantee. However, Xfinity covers approximately 99% of Denver versus Quantum's 75-80%, making it the only wired option in many areas. Xfinity's upload speeds are significantly slower (10-35 Mbps vs symmetrical fiber), which matters for video calls and cloud backup.
Does Denver have 5G home internet?
Yes, Denver has excellent 5G home internet coverage from both T-Mobile (approximately 60-70% coverage) and Verizon (roughly 75-85% coverage). Both offer speeds up to 1 Gbps, no contracts, and plug-and-play setup. T-Mobile has the highest customer satisfaction ratings nationwide and offers a 5 Year Price Guarantee. Verizon offers competitive pricing starting at $35/month with mobile discounts.
What internet do Denver tech workers use?
Most Denver tech workers prefer Quantum Fiber for its symmetrical multi-gigabit speeds essential for video conferencing, cloud work, and large file transfers. The low latency (3-15ms) is important for real-time collaboration tools and VPN connections. In areas without Quantum Fiber, EarthLink fiber or Verizon 5G are popular alternatives. RiNo and LoDo coworking spaces also offer high-speed backup options.
Can I get internet in Denver mountain communities?
Mountain communities near Denver (Evergreen, Conifer, Idaho Springs) have limited wired options due to terrain challenges. Starlink satellite provides 50-250 Mbps with 25-60ms latency and is the best option for remote mountain homes - it's available everywhere. Fixed wireless from local providers may also be available in some foothills areas. Colorado's $420M BEAD funding aims to improve rural connectivity by 2027.
Why is my Denver internet slow?
Slow internet in Denver often results from network congestion during peak hours (typically 7-10 PM), using older DSL infrastructure instead of fiber/cable, distance from provider equipment, or outdated home networking gear. Denver's altitude and weather can also affect wireless signals. Upgrading to fiber or 5G home internet typically resolves speed issues. Try running speed tests at different times to identify patterns.
