Use our speed test to determine the performance of your broadband service whether you use RCN or another provider. The modules above will return statistics for download and upload speed. These metrics are the most important signs of broadband internet connection robustness. As of February 2021, RCN’s national average download speed is 137.57 Mbps. Throughout their coverage footprint, the average latency on RCN Internet speed tests is -1ms. In context, wired terrestrial connections generally output latency results in the 5–70ms range. Satellite broadband connections, in contrast, are often in the range of 500–800ms.
