Adapter slows down cable speed

by Jerome Leon / January 24, 2008 3:03 AM PST

The things you accidentally find out. My computer has seemed quite slow. Every once in a while, I follow the usual advice for speeding things up, but to no avail. I have Comcast cable and use Vonage for my phone service because I pay Vonage only about fifteen dollars a month and Comcast phone has been twice that. Today, I was offered a deal by Comcast that made it competitive with Vonage so I am switching over. I also asked the Comcast tech about my computer speed. He said I should be getting 8.0 Mbps. He asked me if I was using an adapter and when I told him I had the Vonage adapter, he said that would slow my speed down to about 4.0 Mbps. I thought there might be others who would profit from this information.

I don't know why Vonage tells people to put their adapter between the modem and the router. All you had to do was plug your Vonage adapter into your router and your internet will fly, your Vonage adapter will connect to the internet and work fine. Some people set their QOS setting for the port that you plug your adapter into. I don't see a difference either way.....FYI, comcast is twice the price of Vonage's $15 dollar plan, without all the features that Vonage offers.

QoS settings on adapter can fix router speed problems
by gsiebengartner / November 30, 2009 8:28 PM PST

I keep getting connection errors from my Vonage adapter, so decided to put it between my modem and my wireless router. Result was it dropped my wireless network speed from 9.x Mb/s to less than 3 Mb/s - not acceptable. I then logged in to the adapter and ramped up all the QoS settings to their max. Seems to have fixed the problem - I'm back to my original speeds.

This was not a scientific fix - I just thought I'd give it a shot, and it appears to have worked.
