Yesterday was a crazy day to say the least. My 3 day old router started going crazy. My service is 20Meg down, 2 Meg up. The down was anywhere from 4 Meg to 12 Meg and the up was consistantly at 256 kbps. I'm surprised how well ooma sounded, at least that is what my callers told me.

So late last night I replaced the router (both were/are Linksys WRT320N) and my speeds are back to normal. A consistant 2 Meg up.

I was wondering if I could get a tip on what to set my QOS to in the router. Here is what I've got:


VoIP test statistics
--------------------
Jitter: you --> server: 1.0 ms
Jitter: server --> you: 0.6 ms
Packet loss: you --> server: 0.0 %
Packet loss: server --> you: 0.0 %
Packet discards: 0.0 %
Packets out of order: 0.0 %
Estimated MOS score: 4.1

Speed test statistics

Download speed: 6569168 bps
Upload speed: 2130624 bps
Download quality of service: 96 %
Upload quality of service: 98 %
Download test type: socket

Estimated download bandwidth: 17600000bps

Download TCP forced idle: 59 %
Maximum route speed: 7281664bps

Thanks

You had some discussion on placement of the hub relative to the router in this thread: viewtopic.php?t=1951. I assume since the router's QoS is the question here that you elected to keep the hub behind the router. I'll also assume that the router's firmware is the standard Linksys WRT320N version. There are several folks here who can recommend how to set it up, but unless someone here is already familiar with that router's QoS interface, it may be helpful if you could post a link to the owner's manual so that recommendations can be made that are consistent with the router's capabilities.

The ability to specify ports for QoS seems limited to three entries per device if done manually, but in Chapter 3, Page 24 there appears to be a pre-configured entry for “Voice Device” that only requires you enter the MAC Address for the hub, and then give it the highest priority. If you later set up QoS for other device/applications, you should give them a lower priority.

Thanks for pointing that out.

So if using the pre-configured entry for VOIP, would I leave the upstream bandwith at Auto or put in some value?

Thanks

Everything I've read says that consumer class routers do not do a very good job determining bandwidth. Consequently, it is usually better to enter a number. First go to a speed test site such as http://www.speedtest.net/ and do a few tests. Note your average upload speed and take 80% of this value and enter it into your upload QOS field (didn't see if your router/firmware does download Qos).

Based on the test results posted you have no need to change anything

Thanks to all who have responded. It seems I get the best performance not enabling QoS in the router

Thanks

Did I see correctly on an earlier post in a different thread that you are hosting a website? Depending on the site traffic, you might have issues with your outbound call quality during busy times.

Hello,

Yes I host a website, BUT the volume is very low as it is a niche market.
