Is there a way of checking the modem before just buying a new one. It is one that the cable company installed.

If the cable company installed it and you are paying monthly rent on it, take it to the cable company service center and ask for a new one.

The modem checked out fine. We are still having problems with stutter. It is driving me crazy!

Maybe "stutter" is the wrong way to describe it. My husband thinks more like a flutter, or quick buzz. It happens with every call multiple times. The other person doesn't seem to hear it, but it does cut out what they say, so I miss a second or two.

dray1:

Some Ideas:

From your description and test results, it sounds like you are not getting a consistent or a steady signal from your Internet provider.

Your Internet signal still has to go through your modem. So even though it was tested, it still might be defective or not setup correctly.

Is your modem’s firmware up to date?

Is there a way to reset your modem to factory defaults and start over?

What is you modem manufacture and model number?

Can you borrow someone else’s modem just for testing?

Call your Internet provider and tell them that your Internet signal seems to be surging.
Tell them that you intermittently have high jitter and loss packet rates.

You are not supposed to have packet loss. Something is not right with your network setup. Just because you have Internet and surfing works doesn't mean ur modem is fine. What do u mean by the modem checks out?

The modem was installed by the cable company. i can not remove it and try a different one. The modem is an ARRIS. There is no model# on it. when I was on the phone with my ISP tech, he did some sort of test and found nothing wrong with the modem. He also reset for me on his end (I have no control over it). When I do the speed checks through the local speedcheck site, my speed results are fairly consistant. He saw consistent speeds on his end too: close to 8 Megabits/s for download and close to 1Megabits for upload. When i do the tests through the national sites they are more inconsistant (he stated it was due to the disntance of the test sites. True, my jitter and packet loss results are inconsistent, he didn't have an answer for that since everything looked right from his end. I wonder if the jitter and packet loss results also are affected by the distance too? Is there anyway of checking to see if there is something wrong with the ooma device itself? I am at my wits end. Everyone here says it is my isp or modem, and they say it must be something else. I was ready to go out and buy a new router, but it happen even when set up directly to modem. Also happened with corded phone.
