My Cox Business Internet review
Sep 15, 2025 | Share
Cox Business Internet delivers reliable cable and shared fiber plans for small to mid-sized businesses, with speeds up to 2,000Mbps (2Gbps) and features like unlimited data and optional LTE backup.
For larger enterprises, Cox also offers dedicated fiber, customized high-speed plans with guaranteed bandwidth and service-level agreements (SLAs). While shared plans are more budget-friendly and widely available, they don’t offer the same performance guarantees as dedicated fiber. If consistent, high-capacity performance is critical to your operations, Cox’s dedicated enterprise solutions may be worth the investment.
Fiber access is limited in many service areas, and Cox plans are often more expensive with lower speed tiers compared to other business internet providers, especially once promotional rates expire.
Pros
Fast, reliable cable and fiber internet
Unlimited data with all plans
LTE internet backup option
24/7 premium technical support
Bundling discounts available
Cons
Expensive compared to the competition
Limited fiber availability
Standard plans are better suited for SMB or retail locations
Higher promotional rates after the first term

Equipment
With a Cox Small Business Internet plan, you’ll have the option of renting the Panoramic Wifi Gateway, or providing your own certified equipment. Professional, tailored installation or self-installation options are also available.

Cox Business contracts vary by plan. Customers can choose promotional pricing with a 12- or 24-month term agreement or pay higher rates on a month-to-month option.

Cox Business Internet: My final take
Cox Business Internet covers the basics with reliable speeds, unlimited data, and plans designed for everything from small shops to large enterprises. LTE backup on select plans provides dependable failover protection to maintain business continuity during outages, which is especially valuable for businesses that rely on point-of-sale systems, video calls, or cloud tools.
Many Cox plans require contracts, which can feel limiting as other providers move towards flexible, no-contract options. Pricing is a little higher than average once equipment and setup fees are added, so it really comes down to whether the extra features make sense for your business. Cox Business Internet is a reliable option with useful benefits that can be worth it if they match what your team needs most.
Cox Business reps can walk you through the choices to find the best fit for your needs.
