Speedtest.net vs Cox's Speed check - Why is there such a huge difference?

Hi everyone!  When I do a Cox Speed Check, I get about 120m, but on speedtest.net it is about 40m.  Why is there such a huge difference?

Results can vary a bit based on location, distance, and a variety of other factors.  For best results we suggest testing with wired connection.  You may also want to try several tests to see if you get a more consistent patter of results.

It is a wired connection.   The other sites are all about the same with a 50% loss of the paid speed, while Cox speed check is usually about 95% of the paid speed.  Very interesting of the Cox displayed speed.

Hi RansZ28, can you run a traceroute? It may help determine what it happening. Also, is your wired connection directly to the modem or are you going through a router. Please let us know what brand/model of modem and router or combo unit you are using.

I have a direct wired connection to Netgear CG4500BD.  

These speed test were done consecutively (Mbps):

Cox SpeedCheck (PHX Market) = 117.03 down, 11.98 up.  Latency 7 ms

Speedtest.net = 33.25 down, 11.94 up. Latency 14ms

Thank you for the traceroute. Please try another traceroute to a site you normally would go to or stream from and post the results.

Hi @MichaelJ - I posted the trace route, now what?  Is there any solution?

The trace route to our server does show a small spike but nothing that would be picked up as a issue 40 ms is still normal, 50 ms is likely a spike in traffic over those servers but still would not be noticed. The other tests appear normal for leaving the network with no noticeable spikes.

With the Speedtest.net result did it reference the location of the server it tested to get the 30 Mbps download result?
