Vonage Hello all. I found this in a Comcast customer forum and was wondering what some
Hello all. I found this in a Comcast customer forum and was wondering what some of the experts here think? I tested the IP on my own connection and indeed, it started with a 24.xx.xx.xx. According to this post, Comcast has been routing these IPs to another network. Any thoughts??
COMCAST QOS'ing Vonage-LinkSys MAC addys? Jan 28, 2006 2:49 PM
Is Comcast working to control Vonage usage on their lines in TX?
I've been using Vonage in DFW Texas since May (WRT54GP device) and I had 6 months of GREAT service until recently when Comcast started having outages for my house.
I know that Comcast fixed some valid issues with their upstream/downstream power (as well as EMI in my area) so I know they've been very honest with me on that front; however, I still seem to have a perfectly-sync'ed modem that experiences latency and packet loss. Further, I noticed something odd that makes it appear that Comcast is corraling Vonage users into a special nework branch??
Here's what I see:
When I use a regular NON-Vonage router (with a differing MAC address) my cable modem pulls down a 67.187.x.x IP address. If I use my Vonage router I get a 24.1.x.x address EVERY TIME!
This is completely reproduceable, and very odd. I did some traceroutes to see where these two different IP networks are, and the 67.x.x.x ip goes to a "TEXAS-16" network in Cherry Hill, NJ and the 24.x.x.x goes to Mt Laurel, NJ "TEXAS-8" network (I'm in TX but I guess NJ is where my Comcast has its peer-point from TX? Weird.)
When I do Speakeasy.net tests with the non-Vonage router I get great speeds of about 3000kbps downstream, and when I do speakeasy.net tests using my Vonage router (with my phone NOT in use) I see about 1700-1800kbps downstream with a lot of packet drops.
My non-Vonage Router is a LinkSys RV042, my Vonage router is a Linksys WRT54GP.
If I do a MAC-Clone and point my Vonage router's MAC -> to the NON-Vonage router, it too gets DHCP'ed to this 24.x.x.x network. No Vonage MAC involved and I get the other 67.x.x.x network EVERY TIME.
Anyone have any thoughts or is anyone else experiencing this with Comcast or any other ISP? Is this just QOS or is it something else??
I may have drop Vonage to make my COMCAST problems would go away entirely?? Right now, my Vonage is completely offline and my service is great.
Help!

Hi Anon1553143,
I did not pay attention to the IP address that I got when I placed the Vonage router downstream of my modem and upstream of my US Robotics 8054 wireless router. What I did notice is that I got better speed when I placed the US Robotics router immediately downstream of the modem and upstream of the Vonage router. So thats what I do now..... modem to wan port of my US robotics router to Vonage router (just run the ethernet cable from one of the 4 ports on the USR wireless router to Wan port of the Vonage router). I give the Vonage router a static IP address off of the US Robotics Router. Vonage claims the placing the its router downstream of the main router could compromise voice quality but I have had no problems with that (of course I pay $10 more per month for the 768K upload speed since upload speed is supposed to be the crucial factor in VOIP). Also another trick....run the male-male phone cord from the Vonage adapter/router directly into the nearest phone jack (instead of into the nearest phone). By doing that, I have dial tone on all the jacks (4) from the 2nd floor, 1st floor and basement (powering 4 base stations 2 more corded phones and a fax machine with VOIP..... using splitters of course. I'm sure this works with any Voip adapter/router. I just happen to have Vonage.

Bottom line from (my long-winded) post above: Connect the ethernet cable from your cable modem to the Wan port of your LinkSys RV042 (non-Vonage router) then run an ethernet cable from your LinkSys RV042 in to the Wan port of your Linksys WRT54GP (Vonage router). Give your Vonage router a static IP address that does not conflict with your DHCP range but consistent with your router (for linksys usually 192.168.1.XXX). If you have multiple jacks in your apartment or house, run the phone cable to the wall jack and power the place. Man I can't escape being long-winded! Good luck with your Voip!
