LOCATION:Detroit, MI, Comcast, cable

SPEED:dslreports.com speed test result on 2006-06-27 19:40:54 EST:
4910 / 298
Your download speed : 4910 kbps or 613.7 KB/sec.
That is 16.4% worse than an average user on comcast.net

That is 28.7% worse than an average user on comcast.net

MODEM:TOSHIBA PCX1100U

ROUTER: TRENDNET TEW-611BRP

Vonage ADAPTER:LINKSYS RTP300

SETUP:CABLE MODEM -> ROUTER -> Vonage ADAPTER

PROBLEM: CAN'T LOGIN TO Vonage ADAPTER (LINKSYS RTP300) USING THEIR DEFAULT IP 192.168.15.1.
TRIED CONNECTING Vonage DIRECTLY TO CABLE MODEM AND STILL CANNOT LOG IN.
WOULD LIKE TO SETUP "PORT FORWARDING" BUT CAN'T FIGURE OUT IP ASSIGNED TO Vonage RTP300.
WHY AM I DOING THIS? BECAUSE THE PHONE CONNECTION CONSTANTLY DROPPING CALLS AND/OR CHOPPY, PLUS INTERFERES WITH INTERNET CONNECTION.
HAD A LINKSYS ROUTER, THEN REPLACED WITH TRENDNET ROUTER. NO DIFFERENCE.
SHOULD I GIVE UP ON VOIP/VONAGE?

give up on the pcx1100 and I bet your problems will go away. here are a few examples I have on hand.

port forwarding isn't needed and won't make a difference. make sure you have a computer connected directly to the rtp300 to log into it.

Thanks for the input John. If I need to buy a new cable modem, is there any highly recommended by this forum?

A Motorola Surfboard is always a good choice.

Its seems some users have had problems with the SB5120, and its DOCSIS 2.0, so be cautious. A lot of users have reported having success with "downgrading" to a SB5100 and its DOCSIS 1.1, but it seems the main thing is to have a DOCSIS 1.1 compatible modem.

Put the weapon/Vbox down and stand away from the edge. Wink

Toshiba or not you have a connectivity issue with the rtp300; which is a separate issue. You may need to factory reset the rtp300 to get access. You could try just setting the rtp300 on the desk with only power and the computer into the lan port access the setup 192.168.15.1 .
You should have a routing/client table somewhere in the Trendnet setup pages to get the IP assigned to the rtp300. Or you can get the IP from the rtp300 if your computer is connected directly to one of its lan ports(whether it's wan is connected to the modem or the tew611). Personally, If you get calls to go through at all then you probably don't need the port forwarding.

BTW the superdan Voip test http://www.vonage-forum.com/voip-speed-test.html looks pretty much on par with mine, marginal Jitter. The modem may be your issue with sound quality like reebok said. Run the test when your sure you're having voice quality issues. AND run it again with only the computer hooked to the modem at least once. This may eliminate everything behind the modem as being the cause of the problem.

That's a bit of a misconception. All the SB5xxx models are both DOCSIS 1.1 and 2.0 compliant. The 5100, 5101, and 5120 are 1.1 and 2.0. I think that guy's problem was something completely unrelated.

Thanks EzCo! I was just going off something I saw earlier about the modems, wasn't 100% sure. The Comcast thread had a lot about that stuff.

Thanks for the input. I see you are using the Surfboard modem 5100, I've read pretty good reviews about the Surfboard - Do you experience any internet connection flutters/hesitations?
I will run the test again during "problem areas" and I think I might take a shot at Comcast replacing with a better modem. I could get lucky =) If they give me a Surfboard and things work for the better is it wiser to buy or lease the modem?

I personally think buying is the better option. Comcast charges $5 per month for rental, so after a year of rental charges, you've basically spent enough to buy the thing. It's also nice to have the choice of what you get. I know Comcast generally gives you whatever junk is in the truck. When I signed up they gave me an RCA modem and I had sub-par performance. But, you can't say anything about that to them because they don't "guarantee" speeds. After I bought the Moto and ditched the rental, my download, and especially upload speeds, were right where they should be, if not a little better than advertised.

Two downsides to owning are if it goes bad, you have to buy another one. But, at their current price point, that's not much of a bruden for most. The other is your cable provider could try to blame your cable modem if you call for an issue. However, that's pretty easy disprove by asking them to send a tech with a modem for testing purposes. If you have a problem and they put a new CM on your line and it clears up, you know you'll probably have to go get a new one.

Those were two issues I thought of when I switched from rent to buy five years ago. So far, I haven't run across either issue.
