Title: Cablevision: Voip - internet speed issue
Post by: Bruceee on October 13, 2008, 11:29:33 AM

Hello,

I am on Cablevision North New Jersey.  Cablevision recently forced the triple play package on me even though there offering is inferior to Broadvoice's offering.  I never use cablevision's voip product, but in order to keep the bill down, I need it activated and on my account.   

When I connect directly from my desktop to Motorola SB5120 I get speeds of 6000 to 8000 kb/s.  When I put the dlink router in I get good speeds, but over time, about a half hour, it comes to a creeping halt.  The speeds deminishes to roughly, 350 kb/s.   

I've just swapped out my DIR655 for the DIR825.  Same result. 

Here is what is hanging on the network: 
Mot SB5120 with internal Voip active ->Dlink DIR825-> Broadvoice Linksys spa2102
                                                                         /      \
                                           Infrant ReadyNAS NV<         >gigabit network adapter in desktop (GbE LAN-                                                                               Onboard 10/100/1000M PCIE controller)
The router is 1st after the sba5120, and the broadvoice dangles off the router. 

There are 3 laptops connecting via wpa2 and draft N, and a  Wii which rarely gets turned on.

What's happening and what can I do to solve my speed issues.

Does the issue with the speed happen on all computers or just 1?


Also update your firmware. Most likely that won't make a difference but it's good to get it up to date.

It happens across all machines.

When I disconnect the linksys spa2102 the speeds through the router are as fast as they were when directly connected to the sb5102.  I put the spa2102 in the dmz and opened the SIP in the firewall.  What else do I need to do?

The Voip I'm using is Broadvoice, and they allow for bring your own device.  Are there better devices out there?  I realize I'm on the d-link forum, but unbiased opinions would be appreciated.

Issue Solved:

Moved the linksys into the DMZ
open sip in the DIR-825 firewall

Speedtest.net results after these moves:
19444kb/s down
4580kb/s up
