Comcast + WRTP54G = data problem

Posts: 2 · New Forum Member Joined: Oct 10, 2008 Posts: 2

I have a WRTP54G behind an RCA cable modem, provided by the fine blokes at Comcast. I used to have a Scientific Atlanta modem, provided by Comcast. Behind this modem, I have a WRT54gP2 router provided by Vonage. I'm getting massive, random packet loss and comcast blames Vonage, and vice versa. Comcast will be out here on Saturday, but this has been going on a month or so. Calls on the Vonage line often cut out, my IM sessions don't stay logged in, gmail times out constantly. The kicker is that a neighbour of mine has an open wireless lan, which I've been using to get online. They also have Comcast and things seem to be working fine. This is in San Francisco. Any assistance appreciated and thanks in advance.-- H

Try connecting the pc directly to the RCA and check to see if you are still experiencing packet loss. Try using www.voipreview.org and find the link in the middle of the page that says "voip speed test" Good testing program, will give you much information. Do this with the vonage connected and without the vonage connected. This should allow you to see if the vonage device is the culprit or the ISP. Also make sure you have good quality cat5 cables and that all devices are separated from each other about 2ft at least and not close to the monitor,TV....etc to avoid possible interference issues. If you are using the wireless network make sure its secured and also away from 2.4 GHz phones if applicable. There can be many avenues to check in internet service disruptions>ping tests, nic tests, tcpip stack corrupted?........etc. You can use the power of the speed test if there is something going on to approach the ISP with. After all, you need to get the speeds dwnld and upld that you are paying for! Call in to vonage for further help. Good luck

Ok, I get packet loss with or without Vonage connected. Indeed, I ran a traceroute-like program that showed that the packets were being dropped at a level-2 router in the Comcast network.
