Comcast Xfinity speed test
We think it is unfair when ISP offers own hosted tests of speed. It's very important to use third-party judgment. When ISP's speed test shows your speed it can be overstated.
Our speed test checks all providers on the same measures, so your internet speed would be shown as is.
