My internet speed drops significantly with ooma useage. I have tried connecting ooma in front of and behind my router and the same problem persists. Initially my internet speed test is about 25 mbps. After about 4 calls my speed drops to about 10 mbps. After 6 to 10 calls my speed test indicates a speed of about 1.5 mbps. I then unplug my router for 20 seconds, then power it back on, and I'm up to 25 mbps again. Until I use ooma and the cycle starts anew. I have updated the firmware for my Belkin N600HD dual band router but it didn't make any difference. This has to be an ooma issue and any advice would be appreciated before I toss the unit. Thanks

To help stabilize your Ooma Internet connection turn off MAC address Spoofing, which can cause dropped calls, garbled voice, and other problems, by doing the following:
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. Click on Internet, go down to INTERNET Port MAC Address: and change setting from Automatic to Use Built In. Click on Update device. Remove power from your Modem and the Ooma Device. Repower the Modem. When the Modem is done booting repower your Ooma device.

If your connection is Modem-Router-Ooma or 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. Click on Internet, go down to INTERNET Port MAC Address: and change setting from Automatic to Use Built In. Click on Update device. Remove power from your Modem (or Modem/Router), your Router (skip to Ooma Device if have Modem/Router) and Ooma Device. Repower the Modem (or Modem/Router). When the Modem is done booting repower your Router (skip to Ooma Device if have Modem/Router). When the Router is done booting, repower your Ooma device.

For Modem-Ooma-Router connection:
Access the Ooma Setup by typing http://172.27.35.1 in your computer browser window. Click on the Advanced tab. Under Quality of Service set both the Upstream Internet speed and Down Stream Internet speed to 80% of the measured Upload and Down load speeds as measured by http://www.phonepower.com/speedtest. After running Phonepower Speedtest, click on the Advanced tab at lower left side of Phonepower test results window. Take the Download Speed and the Upload speed, and multiply .8 times for each number. The resulting numbers are the numbers that you enter into Ooma Setup, Advanced page under Quality of Service Upstream Internet Speed (kbps): and Downstream Internet Speed (kbps): boxes. Click on Update. Then test making and receiving calls.
