Not all speedtest.net servers have the same data rate capability. If you're looking to run a test with the CGNM-3552 installed, use the Toronto Telus server. It will give you a better result. I believe that speedtest.net chooses your server based on ping time, which may result in using a server that isn't the fastest one around.
dang must have missed that one only one i could see was this

Those results are a little strange. The best that I've seen from the Toronto Telus server is 940 Mb/s with a direct connection to the modem as it was running in Gateway mode. Trying to remember the Rogers Speedtest results, I don't believe that it was anywhere above 900 Mb/s. Somewhere in the 870/880 range.
With the CGNM-3552 in Bridge mode, my Asus RT-AC68U in full router mode, the best I can do is about 810 Mb/s from the Toronto Telus server.
Are you running the test with the modem in Gateway mode or Bridge mode with a follow-on router?
Here's the same tests to Kingston and Rogers, thru my RT-AC68U;

Server Cloud Canada 21 183 34
WTC Communications 45 90 25
Rogers Speedtest 31 703.5 36.8
Just to note, the WTC Communications test takes a while to start, maybe its a single test server. When it does start, its actually pretty fast, but, the test times out just as the server is picking up steam, so to speak. I think that if the test actually ran longer, you would see higher results.
