Yes, I use a corded phone connected directly to my Ooma, because as you point out when I first encountered problems I wanted to eliminate all other possible sources of noise/problems. With my internet connection and router testing well, I'm pretty sure that my set up needs new settings, but I'm out of ideas.

I'm afraid to switch from Modem-Router-Telo because while the quality is poor, I struggled for months without success to have an operative system with the Telo in the middle.

This way will helps you to tell if the phone is the problem or not. It's known that pre Dect. 6.0 cordless phone interferes with the 2.4Mhz bandwidth many wireless router using.

richard7: When doing the test above, you must remove power from your cordless phone base(s). Again, even if the cordless phone cord is disconnected, you must remove power from all of the cordless phone base(s) in the home. Often a cordless phone base will cause noise problems as long as it is powered.

richard7 wrote:I have this problem even when my computers are off, unfortunately. In addition, there is constant noise on the line, a grainy, distant sound that pulses slightly, as though searching for a signal on a ham radio. It's annoying as hell. Plus my internet connection tests well, so while I've had problems with my provider in the past, the connection is has been upgraded and is fast with plenty of room to spare.

I that by going Modem-Router-Telo I would avoid interference with computers, but I am at a loss to explain why my connection is so poor no matter what I try.

You may have missed the point that I was trying to get to for this part of your problem. You are testing to see if there is a problem with your computers when browsing the web. If the computers have stalls, stops, or slow downs, then that tells you that there is an Internet problem, not a Ooma problem, even if the Internet has been working fine in the recent past.

I understand now the point you were making with respect to signs of problems, noticeable slowdowns etc., with computers. My internet connection is performing well and I see no signs of a problem. I just tested it again using my macbook pro (wirelessly connected) and will attach the results.

I have a Panasonic Dect. 6.0 system but haven't used it in months b/c I don't want to risk introducing any problems over and those stemming from my Ooma system. I have two brand new corded phones (not AC powered) connected directly to the back of my Telo. And I have separated the Telo from my other electrical components and kept its wires separate too.

The pulsating aspect of the constant dirty noise I described is almost eliminated when I hold the Telo between my hands, leading me to believe the problem is related to grounding. Is there a known issue here? The adapter looks cheap and there is no third wire. Is there a way to address this problem?

First:
The Ooma Telo Power adapters have caused problems in the past. The Ooma Telo requires a power adapter that puts out 5 VDC 2 A, voltage and amperage requirements as viewed on the label on the bottom of the Ooma Telo. Try to find another power adapter with the correct output values and test.

Also:
Run http://speedtest.phonepower.com/ to see how your modem and Internet connection is doing. Then click on the Advance tab on the lower left side of the Phonepower page, and post the following values here in this thread, by clicking on "Quote" in the upper right hand corner of this Ooma Forum post. Then fill in the blanks.

If you do the Java fix in your computer, instructions located at viewtopic.php?f=9&t=12085. Then you can click on the Speedtest Phonepower Advanced tab, then "view test" at the bottom. Instead of filling in the blanks above, you can select CTRL+A to highlight, CTRL+C to copy; CTRL+V for paste into the Ooma Forum.


If the Power adapter test is okay, try the following:
Ooma Telo Factory Reset (which sets all Ooma Telo setting back to factory new settings):
Dial *#*#099 on the phone attached to Telo to issue a factory reset.
A recording will come on the line and ask if you really want to do a factory reset. Press 1 for yes, and press 2 or hang up for no. After pressing 1, you will hear a busy signal. After hanging up, the number 1 light stays lit yellow on the face of the Ooma Telo. After a short period of time, only the number 1 & 2 lights remain lit blue. Then after more time, the Ooma Telo goes into the boot sequence, and comes back on line.

You will have to reset MAC address to Use Built In. At this time don't reset your Quality of Service Upstream/Downstream Internet Speed settings, leave them at the factory reset default settings.

Sometimes the *#*#099 command has to be issued three or four times, before the factory reset sequence starts and is completed.

After the factory reset, do the following:
Power off the Ooma device for 20 minutes. This allows time for the Ooma servers to reload/reset your Ooma profile. Then repower the Ooma device and test.
