My phone was working until this morning. I thought I had all the settings correct.

Ooma Telo is set to Statis IP Address: 192.168.1.105 (DMZ Enabled)
QoS settings: Ooma (High) and in Ethernet Port 4 (High)

Someone set this up for me.

On my Linksys Router WRT54GS there is Network Address Server Settings
Static DNS 1 & 2 have numbers. I don't new what they're for, but 192.168.1.105 isn't listed. Should it be listed here?

On the Ooma Tele there isn't anything listed for DNS Server 1 or 2.
Under DmZ there isn't anything listed. Should 192.168.1.105 be listed there?

I'm not a techy person so forgive me for not knowing what I'm talking about. If DMZ is Enabled in on my Linksys router, what settings need to be changed on the Ooma Telo.

Rita: You didn't say what wasn't working.

Gain access to Ooma Setup. When the Ooma Setup pages open, click on Internet.

Go to Internet Settings, than Connection Type. Click on the down arrow and select Static IP address.

Go down to Static IP Address Options:
Behind IP Address: put 192.168.1.105 in the boxes.
In netmask: put 255.255.255.0
In DNS Server 1: put 192.168.1.1
In DNS Server 2: put nothing
In Router Address: put 192.168.1.1

Click on Update device.

Unpower the Modem, the Router, and the Ooma Device.

Repower the Modem. When the Modem is repowered, repower the Router. When the router is repowered, repower the Ooma device.

Next time you have a problem first reboot (unpower and repower) everthing, to see if that helps.

If you are still having problems let me know exactly what is happening, or what isn't working. Ooma lights flashing? No Ooma dial tone? Bad Quality of Service?

Thanks so much! There wasn't anything next to DNS Server 1: so I entered 192.168.1.1.

I can hear the person I'm calling just fine. The other person complains of my voice getting cut off. It's better than what it was (before they said I was coming in and out--not able to hear me at all at times). Now it just seems it's cutting in and out, but they can still hear me.

The QoS (in Ooma) is set to 0 for upstream and downstream speed. Someone earlier said to set it to 5,000. Would this help.

Rita: The out of limits indications above show that probably your Modem is failing or your Internet connection is defective.

I believe there are reset buttons on the back of your Dlink/comcast 202 Modem.
Maybe you could call your Internet provider and see if they can help you with a Modem Reset, than retest.

Or better yet, if you are renting your Modem have the Internet provider give you a replacement Modem.

If I unplug Ooma, it seems that my speed is in the green with my Linksys Router, but when Ooma is plugged it it really slows everything down? I bought new phones last week. I'd hate to go buy a new router to discover it's now a router issue.
