Toots:
While you are researching uVerse, find out if you can get just a Modem from ATT, not the Integrated Modem/Router for the uVerse. There seems to be much more trouble with the integrated Modem/Router.
Notice: If your Ooma is working okay, don't change any Quality of Service settings. I just posted the information so that you would know how setting QoS is done.
If your Ooma device is connected Modem-Ooma-Router, access your Ooma Setup pages by typing
http://172.27.35.1 in your computer browser window. The Ooma Setup pages open.
If your connection is Modem-Router-Ooma, temporarily connect a network cable from your Ooma device home port, to the wired LAN port of a computer. Temporarily turn off Wi-Fi in the computer, if turned on. Reboot the computer. Access your Ooma Setup pages by typing
http://172.27.35.1 in your computer browser window. The Ooma Setup pages open.
Setting Quality of Service:
Since your Ooma setup is Modem-Ooma-Router, this is what has working other people with this setup:
Access the Ooma Setup Advanced page. Under Quality of Service set both the Upstream Internet speed and Down Stream Internet speed to 90% (before the last firmware update it used to be 80%) of the measured speeds as measured by
http://www.speedtest.net/. Click on Update. Then test making and receiving calls.
Others, especially with higher Internet speeds, have reported that this has helped them:
Access the Ooma Setup Advanced page. Under Quality of Service set both the Upstream Internet speed and Down Stream Internet speed to Zero. Click on Update. Then test making and receiving calls.
Still others have reported that this works for them:
Access the Ooma Setup Advanced page. Under Quality of Service set both the Upstream Internet speed and Down Stream Internet speed to a higher value, about 1000 Kbps higher, than the maximum measured speeds as measured by
http://www.speedtest.net/. Click on Update. Then test making and receiving calls.
