What Speeds to Expect in North Carolina

Typical speeds for North Carolina residents: 200 Mbps – 1 Gbps on cable or fiber plans. Testing on Ethernet gives you a true baseline—Wi-Fi performance varies by distance from the router and interference from neighboring networks.

Best speeds: Fiber connections in metro areas—consistent performance with symmetric upload and download
Cable speeds: Fast download but lower upload; can slow during evening peak hours on shared networks
Rural speeds: DSL or fixed wireless typically deliver 25–100 Mbps; satellite (Starlink) is an option where wired service is unavailable

ISPs at a glance

Provider	Typical offering	Measured speed range
Spectrum	Fixed broadband (fiber / cable / DSL depending on address)	200 Mbps – 1 Gbps
AT&T Fiber	Fixed broadband (fiber / cable / DSL depending on address)	200 Mbps – 1 Gbps
Brightspeed	Fixed broadband (fiber / cable / DSL depending on address)	200 Mbps – 1 Gbps

Measured speeds are wired-test ranges observed across consumer plans; actual figures depend on plan tier, address, and time of day. Always check each ISP's address-level availability tool for accurate plan and pricing information.

Speed Test Tips for North Carolina Residents

Test on Ethernet to measure your true connection speed, not Wi-Fi overhead
Run tests at both off-peak (morning) and peak (evening 7–10 PM) times—cable networks often show 20–40% lower speeds at peak hours
Check upload speed separately—upload is the bottleneck for video calls and cloud uploads, not just download
If your measured speed is consistently below 80% of your plan speed, contact your ISP or check for modem/router firmware updates
