Bandwidth problems

Ok here is my problem I wanted to see the difference in my Bandwidth before I installed the RT31P2. Comcast gives me a 4000 down and 386 up. So i tested it before i installed the phone adapter and got roughly the same as 4000 down and 386 up. Now here comes the problem I installed the new adapter in many ways. I did the default way of cable modem > adapter > router > computer and with that setup I got roughlly 3800 down and 30 up?!?! So i tried the bandwidth option and lowered it down all the way to 30k instead of 90. Let it there for a couple of days and still got the same bandwidth. So i decided to use the phone adapter as my router as well. so it was cable modem > adapter > computer and still got the same bandwidth. So i said forget it and put it back to my other router and got it back up to 4000 down and 386 up. Even with the Vonage speed test it told me that i could use up to 4 high quality phones on it and now its not hardly using one with out killing my net connection. And this is with the phone idling. NOT even in use. Please help?!?! Sad

try modem>router>1 line to adapter, and 1 line to computer. Try that and see if that helps any.

Whenever you have more than one thing using the modem, then you go from modem>router first. The routers job is to route signals to and from different computers/phones/etc. to aleviate any interleaving action. Which I think is what was causing your issue. So everything plugs into a router, then router to modem. This is a standard set-up for lan/wan connections.

doesn't make sense. should't the rt31p2 take only what it needs and lets the rest go to the router/LAN/computer(s) ????

I just got my product about a week ago. I'm with cable one consistently getting 2.2mbs/190kbs.
Original Setup:
Cable modem>linksys befsr41 v.2 4 port>lan to laptop
>lan to tivo
worked great!

Vonage Setup:
Cable modem>linksys rt31p2>lan to laptop
>lan to tivo
Results: For about 2-3 minutes I get close to the same speed, even while phone is idle. THEN it starts eating my bandwidth until there is nothing left. Example> drops to 1mbs/67kbs. Then finally, 200kbs/7kbs Evil or Very Mad

. I've tried many different configs as far as QoS, prioritizing ports, flow control, bandwidth saver. Nothing helps. So just to get it working I did the following connection:

Cable modem>wan befsr41>lan laptop>uplink to wan rt31p2>rj-11
>lan to tivo
>lan to rt31p2
network setup:
befsr41 v.2>192.168.1.1 DHCP/NAT enabled
RT31p2>192.168.1.2 DHCP, QoS, Port priority disabled
NAT enabled.

End Result: Got my speed back, QoS is usually in upper 90's, RTT>40-50ms, MAX idle time 19-21ms. Very happy with the setup. I can open both routers to make adjustments if necessary. Still had white noise until I tried the "short middle pins on rj-11 and insert into port 2" trick. No static, pretty clear, echo almost completely gone. it is only intermittent, now and far and few between. Cool

Here's the clicher, though. Called Vonage tech support Sat night. This guy tried to tell me that it was a QoS issue stopping something from communicating on my computer. He said there was probably a java enbedded trojan called "openstream t". He said he had to restore his computer. His symptoms did not match mine completely, but he did not want to listen. Anyway has anyone gotten this from support before. I do port scans, virus updates, virus scan weekly. I have antivirus enabled on ingoing and outgoing email. I did a search on this virus. Found a few articles on it but it did not mention anything about slowing internet connection. If anyone can find out, that would be great. It just sounds like tech support blaming the customer.

There will always be a bit of loss due to TCP overhead when you're running a program on the internet at the same time you're trying to test it. Your RT31P2 is constantly sending and receiving data while it is hooked up and running. This eats bandwidth. There is a very nice bandwidth test at http://www.2wire.com

how do i stop the bandwidth eatin if i just have the voice terminal and my modem my download speeds have dropped from 300-400 to 100-150 if this persist i think imma just have to get regular phone service.

Perhaps investing in a low cost router would be to your advantage.
