Internet Connect Speed SLOW!

[choreo]

My Set-up...

2012 MacPro 3.33 GHz 6-Core Intel Xeon running Mavericks 10.9.5
Airport Extreme Base Station - Card Type: AirPort Extreme (0x14E4, 0x8E) - Supported PHY Modes: 802.11 a/b/g/n - Firmware Version: Broadcom BCM43xx 1.0 (5.106.98.100.22)
Modem - NEW Arris DOCSIS 3 CM820
Suddenlink High-Spped Cable (up to 50Mbps advertised in my area)
MackBook Pro 17" 2011 Model running Yosemite 10.10.2

Here is my problem. Last week Suddenlink increased the minimum bandwidth in my area to 50Mbps from 15Mmbps. They said I would need to upgrade to a DOCSIS 3 Modem to be able to take advantage of that speed increase however, so they sold me a new modem (Arris CM820) which I hooked up today.

I ran a Speed-Test at http://www.speakeasy.net/speedtest/ both with my old Motorola Modem just before I disconnected it, then ran the test again after I upgraded the modem. I am connected to BOTH my PowerMac 2012 and my MacBook Pro 2011 via the SAME WiFi Network Base Station (Airport Extreme). My older MacBook Pro immediately showed a HUGH Speed Gain when running the speed-test, but the MacPro "download speed" actually went DOWN??? What could cause this?

Mac Pro:
Before: 17.48 Mbps Download | 1.59 Mbps Upload
After: 3.32 Mbps Download | 5.37 Mpbs Upload

MacBook Pro:
Before: 17.32 Mbps Download | 1.52 Mbps Upload
After: 49.36 Mbps Download | 5.58 Mbps Upload

via the SAME WiFi Network Base Station

What do you see with a copper GbE connection?

(Sometimes WiFi really sucks for single user bandwidth, and usually sucks for multi-user bandwidth.)

Do some tests to see if the problem is the WiFi or the modem.

(When I upgraded my Comcast cable modem, I had to upgrade my firewall/router as well. The cable will burst to 200 Mbps, and the older 100 Mbps firewall/router was slower than the ISP link.)

I did find something that may have fixed the bulk of my problem? I ran Cocktail Utility which launched the Network Diagnostics and I could see that "Ethernet" was checked instead of WiFi. I changed over to WiFi and now I am getting the same speed results as on my laptop (which are near the maximum of 50Mbps).

wi fi speed

Make sure all of the wireless devices are running the same connection speeds ie 2.4 or 5ghz if you have one device running in the 2.4ghz range it will pull the others down that can connect at the 5ghz bandwidth also make sure your wireless device can run in the 5ghz range if not you will surely run slower

Your Wifi is better than the Ethernet cable??? Did you use the wrong cable?

I would not think so, but maybe since I did not have the modem connected DIRECTLY to the computer via Ethernet, but had Ethernet selected, it was probably having to go from the Router to my printer hub and back to the Computer?
