Linksys WRTP54G Config / Problems

I recently purchased the Linksys WRTP54G to replace my Motorola VT1000 which was having hardware issues. I am now having issues such as lag on the line, dropped calls, etc. I have gone all around wit Vonage TS and they finally told me that it was a problem with my ISP and latency on the line. However, using DSLReports.com I have the following stats consistently:

~1400Kbps Downstream
~580Kbps Upstream

With that much said, I am curious if I need to better configure QoS for this new device. It is enabled by default and is set to 40% for Low Priority and 60% for Medium priority by default with no rules. This in theory would mean that these are the defaults for all traffic on the device and Vonage related traffic would receive no higher priority than any other traffic. This would explain why I get horrible delay/lag if I am using the connection and also attempting to place a call.

I have already lowered my adapter bandwidth to use 50K instead of 90K, but the results are the same regardless.

Does anyone have any ideas on how to best configure QoS on the WRTP54G, or if it is even necessary? I have explored the manuals and it is not clear on the configuration related to QoS.

I have had Vonage for over 1 year now with no issues until now. At this point I am going on 4 days with terrible phone service and reliability. Any thoughts or suggestions are greatly appreciated. I am open to about anything at this point.

I have already had my adapter updated to the latest firmware by Vonage a few days ago to correct the issue with the router rebooting all the time and such, but the problem listed above is still resident even after the firmware update..

I've read a few posts in this forum and many on the web that this router is shady. As you can tell from my past post, the customer service rep admitted that there are problems out of the box. Fortunately, so many--if not all--of the problems I was having were immediately solved by installing the 1.00.29 firmware. Did the customer service rep send you the *.img file? If so, try installing the upgrade again. Futhermore, disconnect the cable modem from the router before doing the upgrade. This prevents any in-/outbound traffic attempts through the router during the upgrade. It took me at least three times to get an install without errors. I've got the file with some instructions if you need it. Just a thought.

I was able to successfully install the firmware and I have verified that it is in place on the adapter. While the firmware did resolve some of the initial issues I had, there are still several that remain. I am finding that I have to reboot my phone adapter at least once per day, and if I am using the phone I cannot even browse the web without lag occuring with the phone service.

I am still curious if making any changes to the QoS settings would help this issue so the phone traffic has a higher priority, but I am unsure how I would go about doing this. It is possible that Linksys has already set it up that way out of the box, but it is difficult to determine from the config screens.

This is a complete wild ass guess on my part, but my experience with Voip and QoS leads me to believe that since there's not a setting for the High Priority queue that all of the RTP traffic is automatically put in the High Priority queue for us.

Furthermore, it would also make sense that they would not give us the ability to put traffic in the High Priority queue in order to keep us from shooting ourselves in the foot.

Again, complete guess, but I suspect that the High Priority queue is a strict priority queue, meaning that the High Priority queue must be empty before any of the other queues (Medium, Low) would be serviced. Imagine if you have a 384K upload and you decide to put Kazaa or Bittorrent traffic in the High Priority queue. What you've effectively done is break QoS, as those P2P apps will love to fill up the High Priority queue. You can see the damage that can be done.

So, unless you have a reason to muck with it (e.g.: you're running some kind of jitter/delay sensitive app like video), I would leave the QoS settings alone.

about rebooting the router averyday, is your router set to connect on demand? try to set it to keep alive with 15sec redial period
