Average Xfinity Speed Test Vs Speedtest Net Internet Speed

Download Speed
Upload Speed
Ping Latency

The Xfinity Speed Test was conducted in May of this year by more than 12,000 consumers for Ookla, which owns and operates Speedtest.net. It found that the average download speed of Comcast subscribers at 11.5Mbps was significantly slower than other major providers such as Verizon Fios (16.5Mbs), AT&T U-verse (14.7Mbps), and Charter Communications (13.6Mbps).

The following speed test was done using a laptop with an Intel 2.4GHz dual-core processor and the 'Speedtest' app downloaded from Google Play on Android 5.1 with Android's built-in IPV6 support turned off.

Xfinity Speedtest:

Downloaded an app from Xfinity called "Speedtest" - ran a baseline speed test ( took about 3 minutes)      - got ~35Mbps download and ~8Mbps upload-did another run of the same speed test(took about 2 1/2 minutes) - got ~45Mbps download but still 8Mbps upload rate.

Xfinity Speakeasy Test:     

The results of this speed test are from www.speakeasy.net This is a real-time speed test where the user can see their download and upload speeds in real-time which takes into account traffic load all over the nation as well as IPV4 vs IPV6 speed test protocols, or at least that's what it says on their website about how they do their tests.      So went to www.speakeasy.net, downloaded an app, ran a baseline speed test ( took about 3 minutes)      got ~25Mbps download but still an 8Mbps upload rate. Then did another run of the same speed test(took about 2 1/2 minutes) - got ~30Mbps download but again 8mbps upload rate.( So if I'm doing my math right that means Xfinity's Speedtest app is showing speeds 50% faster than what they really are in comparison to Speakeasy.net )   

Xfinity Blast Test:     

Since I had a pretty good idea about what their normal speed was, this time around I turned off IPV6 and ran the speed test with those settings only IPV4.This test was done using www.speedtest.net, downloaded an app then did a baseline speed test ( took about 3 minutes ), got ~35Mbps download but still 8Mbps upload rate. Then did another run of the same speed test(took about 2 1/2 minutes) - got ~45Mbps download but still 8Mbps upload rate.     So, in this case, as it turns out Xfinity's Speedtest app is now showing speeds 25% faster than what they really are in comparison to Speakeasy.net and 20% faster than what they really are in comparison to speedtest.net …

Xfinity Internet Download Meter:     

So lastly I ran the test using an app called "IDM" that I downloaded from the Amazon App store which measures the actual download bitrate as well as other statistics for various streaming sites like youtube, NetFlix, and so on or at least that is what it says on their website about how they do their tests. This test was done using www.speakeasy.net , downloaded an app then did a baseline speed test ( took about 3 minutes ), got ~15Mbps download but still 8Mbps upload rate.

Then did another run of the same speed test(took about 2 1/2 minutes) - got ~15Mbps download but still 8Mbps upload rate.     So, in this case, as it turns out Xfinity's Speedtest app is now showing speeds 2.5 times faster than what they really are in comparison to Speakeasy.net and almost 4 times faster than what they really are in comparison to speedtest.net
