Your signals are on the low side but still within the limits.
A two way splitter will bring them up a little.
A 3 db drop cuts the signal power in half going from a 5.5 drop to a 3.5 drop should bring the incoming value up to -6.4 dBmV.

I have and always have had my modem on its side. One thing I did not know is the feed could be moved and place on the side. I do not think my modem is overeheating, but next time I notice a slowness with my connection I will check the modem and see if its getting overheated.

Tomorrow I will go out and buy a splitter, I thought I had an extra one at home but cant find it and see how that works. I also have pixelation on my cable channels on a fairly normal basis with certain channels so I am wondering if a booster would help me. Is there any downside to a bi-directional booster? I have read a lot of great reviews on a few boosters, and think that may be worth a try.

My current download speed is 15.23 and upload speed is 2.83 and ping is 73ms

I just disconnected my cable at the splitter, hooked the modem directly into the feed coming into the house and ran a voip test and pretty good improvement, went from a QoS of the 40% range to a QoS in the 80% range.

I will be picking up a splitter tomorrow and possibly a amplifier, I have also noticed pixelation on my cable and even if I dont use the amplifier on the cable modem end, I think I will get an improvement in TV.

I went out today and bought a amp and it looked like it was helping some but then when I got on the phone still bad, so I went and bought a two way splitter, I could not find a three way splitter that had a 3.5, it was 7.5. So I have two two way splitters, the first one has my modem connected to it, and the second one has the additional splitter for TV. I have not noticed so far any adverse affects on the TV, if I do, I may buy a amp to bump that up I am going to return the one I got today.

I will have to wait till tomorrow to make some phone calls to see if its any better. Since I am having QoS issues, I am thinking about calling my cable provider, not sure how much they will be willing to help me with QoS issues, but if I tell them I have pixelation on watching TV too, they may send a tech out and hopefully can get them to boost my signal. Would having them boost my signal possibly improve my QoS.

Right now I am getting about 80% QoS, which is a big improvement over the 45-60% I was getting before.

I hope this makes a difference.

Would the new PureVoice that Ooma will be pushing out possibly improve my phone conversations ?

I've been following this thread. Two observations:

1. The URL mentioned for link quality analysis, 192.168.100.1, isn't responding to me at this time. My browser gives up after a minute, waiting for the distant one to respond.

2. The speedtest.net site is performing @ just 1.14mbps DN and 0.62mbps UP. This is me, in Atlanta, talking to the speed site, Ookla, also in Atlanta. These speeds are disappointing. I use a Clear WiMax connection that's supposed to hustle along @ around 3.0mbps DN. I guess the 'net's busy tonight.

Maybe 15% of the time I experience the unsatisfactory jitter (dropped syllables) being reported in this thread.

I am about to throw in the towel. I have a week before 30 days to return my Ooma handset and longer for my Telo since I got it at Costco. My port went through smoothly and thats the only thing that is smooth. Sound quality is t r i ble ? Oh you did not understand me, its because I am bre k ng up. I am having serious issues with people understanding when I talk to them. I am have a lot of static on their end or I am breaking up. The past few days I have called my home a few times and each time I hear the horrible quality others are complaining about.

I have modified my QOS a few times and no luck. When I do a VOIP test, I have 40% QOS with the tests.

I really dont understand why I can have so many problems, My download speed ranges from 8mb/s to 21 mb/s and my upload speed is usually 2.5 mb/s or higher, there are times it can get down to 1mb/s .

I have set my QOS to my full reports on my speed test.


Plug your Ooma in to your router...end of problem!
Right now I have my setup as cable modem -> Ooma -> wireless router.

I may tonight try to put the ooma behind my wireless router to see if that makes it any better. I think I have read people having better luck that way, even though the recommended setup is the way I currently have it.

Anyone have any ideas of what I can try before I box up the handset and call Cox and yell Uncle and start porting my number back to them?

192.168.100.1 is only valid if you have a cable modem. It's a web server inside of the cable modem.

Call cable company. You have issue with ingress.Let them fix that. Signal booster will not help. It may make service worse.
Signal on your modem should be -10 up to 10 so your signal is ok. Even with signal -10 your internet should be fine.

I have been in contact with someone with Cox and they are looking at the issue, they have run tests on my modem and..

" modem reporting intermittent bursts of data uncorrectable errors"

The person I am in contact with is very helpful. He found me after I made a comment on Oomas twitter account that I am about to give up, the cox tech guy twitted me.

I have noticed improvement since I have changed my splitter, but still experiencing some issues, hopefully they will be able to fix it since they acknowledged problems with my modem.
