OK, I had things all groovy with Qwest DSL. The phone line came in, direct to the DSL modem. I took ethernet from there, into the Oooma AND into a router for all my computers; the DSLmodem has a four-banger router, so I used two of those out. (and then from there into a wireless roter). The phone line OUT of ooma went to my house. All worked fine.

OK, so I got Cable Modem in now, and it only has ONE ethernet out. So I took that out into the Ooma, and then the out of that into my house router. My problem there is I am wondering if the Oooma makes things too slow.... it is only a 10/100 ethernet, and my internet is supposed to be 6mbps. Or is that ok?

I ran a report, and my cable internet does not seem so good. It uis only showing about 1.5 down, 3 up- supposed to be 6 down, 1.5 up. Weird. Again, is this weird because it all is through the Oooma?

Here is the report. Look how BAD my QoS show, but all the numbers look good. Why?

Last time that I checked 6 was less than 10 and way less than 100. That is not your problem.

Thanks Murph! With all the acronym's and this and that, I was not sure what I was comparing. If what the Comcast was rated was the same quantity and the same magnitude as what the router was rated; that is, whether I was comparing apples to oranges or apples.

So I tested my stuff again this morning, and VoIP gave me approx the same thing again:


VoIP test statistics
--------------------
Jitter: you --> server: 0.9 ms
Jitter: server --> you: 4.8 ms
Packet loss: you --> server: 0.0 %
Packet loss: server --> you: 0.0 %

Estimated MOS score: 4.0

Download speed: 1937688 bps
Upload speed: 3595368 bps
Download quality of service: 81 %
Upload quality of service: 97 %
Download test type: socket
Upload test type: socket
Maximum TCP delay: 198 ms
Average download pause: 9 ms
Minimum round trip time to server: 67 ms
Average round trip time to server: 68 ms
Estimated download bandwidth: 32000000bps
Route concurrency: 16.514526
Download TCP forced idle: 76 %
Maximum route speed: 7825072bps

So I have a good MOS score (4)- better than at Qwest. Little jitter at .9ms, and 2meg down, 3.5 meg up (qwest was 1.5 down, 786 up) So that all looks good. But the overall score for QoS is like 75% and yellow. What is that? Is that something to worry about? Qwest had 95% QoS....

Also, I did a DSL Speed Test, and that showed SUBSTANTIALLY different speeds than this test. Instead of 2meg down, 3.5 meg up, I got 5.3 meg down, 2.05 up (which is about what Comcast says I should have). And the VoIP test has BACKWARDS results- I should have less up than down... I ran both tests within minutes of each other, from the same computer- why such a discrepancy?

Thanks!

I am on Comcast north of Philadelphia. My plan was upgraded to 12/2 sometime ago for free.
I get 15 down and 5 up using their speed test.

The fact that your download speed is lower than your upload speed is suspicious.

What kind of modem do you have?

Connect to 192.168.100.1 and get the downstream signal strength and the upstream power level. Also the SNR if it is there.

The Ooma has QoS abilities and it may be reserving some bandwidth for itself. I would go from modem to router and then just treat the Ooma as just another computer (plug it into the router). You should get your speed back and as long as you don't max out your connection downloading something you should not see any call quality issues.

(10/100/1000 means the router will make a 10mb, 100mb or 1000mb connection with the computer, depending on the network card in the computer. 1000mb is a giga bit connection.)

We go up to 12/2 in December, too. OK, I kinda thought using Comcast to test them might be a bit, uh, suspect, but I did it. Here are the results. Wow, would you look at that- I TOTALLY find 22.5 down 7 up totally outrageous! Should be 6 down 2 up.

Here is DSLTest.com results- about what I would suspect. Again, this test was within a minute of the Comcast test, from the same computer.

I thought so, too, but that is only one test. As we have seen, can't always trust those online tests! :D

The SNR (Signal to Noise Ratio) is 37 db which is good.
The upstream power level is 38 db which is good.

The downstream power level is listed as 0 dBmV
Rerun and get the real number. Anywhere higher than -7 dBmV is good.
(In case you are not a math whiz, -6 is higher than -7.)

I saw very high download speeds while they were installing in my area. Once the installation was complete they sent a new config file to my modem that put the caps in place.

Thanks!

I reran numerous times- looks like "0" IS the number, which is higher than -7, I guess.

So, I am guessing that I do not need to worry about the VoIP test showing me with borderline QoS- everything looks good?

Things SOUND good, so far at least!

You're right. I guess I'm still asleep. I've never seen the reading hit exactly zero.
You're signal levels look good and you don't have the modem that I have that has overheating problems.
Is there anything running in the background on that computer or another computer or a network connected DVR that could be skewing the results?

I was listening to a streaming radio show- very low bandwidth- for one test. I realized that AFTER I tested. But nothing else- no Tivo or anything.
