Vonage I'm a recent Vonage customer, having gotten in on the free-after-372-rebates
I'm a recent Vonage customer, having gotten in on the free-after-372-rebates Linksys WRTP54G router. My SBC number was transferred two days ago so I've finally started to use the service. I have Comcast Cable Modem service and so theoretically have 4 Mbps down / 384 kbps up. And I haven't had much problem getting close to 384 kbps via bittorrents or eMule or uploading a file via HTTP.
Today I decided to do a check that the router would properly give the voice traffic priority. I started eMule and set it to use 320 Kbps upload speed. I then placed a call from my Vonage phone to my cell phone, and left a lengthy voicemail, all the while watching both eMule's upload bandwidth report as well as Windows XP's Task Manager network adapter usage (specifying that it show sent and received bandwidth separately). The Vonage call didn't seem to make a bit of difference to the upload bandwidth, although after ending it the router seemed to kill most active connections-eMule dropped down to 0 Kbps, IM connections were reset, etc. Not surprisingly the voicemail I left sounded horrible... very choppy, coming in and out.
This lead to some web searching and an hour-long call to Vonage, the first 30 minutes being taken up by a support person who couldn't seem to understand that I was telling him I indeed had sufficient upload bandwidth to use Voip but that the problem was that the router wasn't properly giving voice traffic priority. Eventually he transferred me to a Tier 2 guy, who told me I needed the 1.00.29 firmware upgrade (which I had read about on the linksysinfo.org thread). He proceeded to email it to me and gave me the instructions that I had already read. The upgrade worked (though the level 2 guy didn't seem ready for the "Upgrade are failed!" error message, or the double-progress cycle).
After ending the call and reconfiguring the router to my prior settings, I tested it again. This time I started a 1GB file upload on http://yousendit.com, and then placed a call. Before the call the file transfer was using right around 380Kbps, so it was doing a good job of maxing my upload bandwidth. During the call it dropped to between 230 and 330 kbps at the extremes, but probably consistently averaging somewhere between 270 and 280 kbps. Which suggests that the router was giving Vonage an average of about 100-110 Kbps.
So this would appear to be better behavior with 1.00.29 than with 1.00.18, but the result still is that my outgoing call audio sucked. Once again the other end of my call heard constant clipping from the continual gaps in what I was saying. I could hear fine as I was barely using my 4.0 Mbps download bandwidth.
The Vonage website speed test reported my bandwidth (after turning off any uploading programs) at 4.07 Mbps down / 363 Kbps up. This should be more than enough to have a high quality call and still have bandwidth over for TCP connections. But that's clearly not happening for me. Among the things I'm wondering are:
1. Has anyone else had this same faulty QoS experience with their WRTP54G (particularly if you're running 1.00.29)
2. Is there any router configuration setting I can change to reserve more bandwidth for the voice traffic (my general understanding is that the answer is "no", because the voice traffic is hard coded to "high" priority and so theoretically should all get through).
3. How much upload bandwidth does a highest-quality call use? Vonage's website (and their bandwidth saver) seem to suggest 90 Kbps (and I have my bandwidth saver configuration at the 90 Kbps max), but I seem to recall reading that it would use a fair bit more than that. [marq=right]
And if anyone has any other suggestions or solutions (aside from manually restricting my computers from using upstream bandwidth during phone calls) those would be much appreciated too. Thanks.
Edited to add: In case it's useful, here's a typical result of the Vonage Voip Speed Test, with nothing else running:
Download 4,020,336 bps
Upload 362,872 bps
QOS 93%
RTT 64 ms
MaxPause 47 ms
