jelwell Posted July 23, 2008 CID Report Share Posted July 23, 2008 Cox recently increased upload and download speeds for my Internet service. Uploading changed from about 400 kbps (not sure what it was but 550 kbps was typically measured) to 768 kbps, and downloading changed from 7 Mbps to 9 Mbps. With my computer directly connected, I get more than the advertised speeds. Even Cox states my measured downloading speed to be 10 Mbps. Now, here comes the interesting part or one of them. When I connect my VoIP Analog Terminal Adaptor (aka Gizmo) into the system, my downloading speed remains the same as it was before Cox increased the speed, which runs around 7 to 7.5 Mbps. However, my uploading speed increased to 1 Mbps and much higher, depending on the measuring software. Although I didn't tell Cox I have a VoIP Gizmo in the system, they told me any router would keep me from getting the advertised downloading speed. Why I'm getting more than the advertised uploading speed wasn't explained to me. So experts, why would a router (which is also a part of the Gizmo) attenuate my downloading speed but not my uploading speed? Also, would a cable modem with two ethernet ports solve the speed problem? That is, one ethernet cable would connect from the modem to the computer, and the other would connect to the Gizmo. There's also a curve in the situation. Cox also has a thing they call PowerBoost, which adds additional bandwidth when needed. How is PowerBoost affected by Gizmos and just plain routers?
