Enter a zip code, city, address, or provider name below to see what speeds you can expect in your location for Cox and other ISPs.
Based on the same per-activity budgets as our how much speed do you need quiz.
Now compare your speed to the providers available at your address.
See providers at your address →How we measure: a real-world test to a neutral point on the open internet, not a server inside your provider network, so it reflects everyday speed and can read slightly below best-case on-network tests.
We record anonymized results (speed, latency, your provider and coarse location) to publish honest, real-world speed data by provider. No personal information is stored.

Cox’s fastest available plans reach 2,000 Mbps down / 2,000 Mbps up, and across its footprint typical available speeds are about 1,980 Mbps down / 128 Mbps up. These are advertised “up to” figures from FCC availability data, so no connection reaches them exactly. Run the test above to see what your own Cox line actually delivers.
In real-world tests, Cox typically delivers around a median 293 Mbps down and 102 Mbps up across the plans its customers actually subscribe to.

Providers available in your area come from our coverage data. "Available up to" is the fastest advertised plan; measured speeds appear once a provider has enough independent tests, otherwise we say "collecting" rather than guess.

Cox is available in 1,145 cities throughout the country. Here is a list of top cities with Cox internet service:
Advertised speeds are “up to” peaks measured on an ideal connection. Real-world speed to a neutral point on the open internet runs a few percent lower, and Wi-Fi, older equipment, or peak-hour congestion lower it further. For the truest read of your Cox line, test over a wired connection.
Tests run against the nearest of Cloudflare’s edge locations, so the result reflects your access network rather than a server inside Cox’s own network. We verify each result by network operator, aggregate it as a median (not an average, which a few fast tests would skew), and only publish a provider’s measured speeds once enough independent tests exist. We do not accept provider-submitted numbers.
Run the test above. The connection-quality grade reads latency under load and packet loss, which determine whether calls and games stay smooth, beyond the raw download number.
