I installed Ooma Telo and it seems to work fine but right afterwards our Roku player stated rebuffering the Netflix stream to the point where it can't be watched.

Our bandwidth speed is testing at 14-15 Mbps down and 1.50 Mbps up. We have the Uverse 2-Wire modem/router, model 3800HGV-B so I had to use the modem/router to Ooma to PC setup. We have four wireless devices and three wired (Ooma, Home Theater PC and Roku). The HTPC and Roku are on a splitter off an ethernet cable but the HTPC isn't on when Roku is running. It just seems to be too much of a coincidence that the problem started right after Ooma was installed.

I put the Ooma in the router/modem DMZ and rebooted everything but am still getting a slow Roku. Roku and Netflix say there's nothing wrong on their end. I read here about changing the Ooma QoS and the Ooma IP address but don't see how to change just Ooma in the 2-Wire modem/router. It looks like it only changes all devices.

Not sure what I should do next. Any suggestions?

Thanks much

You need to adjust the Quality of Service settings in Ooma Setup to allow more bandwidth for your LAN.

With the Ooma device in the router's DMZ Plus, it electronically places the Ooma Device directly behind the Modem. Normally the QoS settings for this configuration are 80% of the measured upload and download speeds as measured by http://www.speedtest.net/. (Some people have had to set these settings to Zero. Others have had to set them to about 1000 Kbps higher than the Speedtest.Net readings, to get everything to function together properly).

Temporarily connect a network cable from the Ooma device's Home port, to the Wired LAN port of a computer. Temporarily turn off Wi-Fi in your computer. Reboot the computer. Access Ooma Setup by typing http://172.27.35.1. The Ooma Setup page should open. At the left click on Advanced. Set the Upstream Internet Speed and Downstream Internet Speed to 80% of the measured upload and download speeds as measured by http://www.speedtest.net/. Reboot the Ooma device.

Note: For your home's LAN setup, you may have to adjust the QoS setting a little higher or lower to allow everything to function properly together.

Thanks Thunderbird.

So my PC is already connected to the Ooma Home port and I can get to Ooma Setup via http://172.27.35.1. The Ooma set up instructions said to hook the modem/router to the Ooma Internet port and the Ooma Home port to my PC. Can I just make the adjustments and reboot Ooma or do I need to:

unplug the modem/router
reboot the PC
make the QoS adjustment
power up the modem/router
reboot Ooma

When you say "behind" the modem is that the way I'm set up now? My set up is:
Internet --> 2-Wire modem/router --> Ooma Internet port in --> ooma Home Port out -->PC LAN port

Sorry for the newbie questions

Thanks for your help.

You are right; all you have to do is type http://172.27.35.1 in your computer browser window, make the adjustments, and reboot the Ooma Telo.

If you were looking at your home's LAN connections drawn on a piece of paper, it would start at the left side of the paper, with the Internet coming into your home, connected to the Modem/Router. To the right (behind or downstream) of the Modem/Router, you have your Ooma Telo connected. To the right (behind or downstream) of the Ooma Telo you have your computer connected.
Above are your physical connections. But since you have your Ooma Telo placed in the Router's DMZ Plus, electronically your connections are Modem-Ooma-Router, when considering Quality of Service settings in the Ooma Telo.

Note: most people don't connect anything to the Ooma Telo's Home port during normal use when the Ooma device is connected physically behind the router. Instead they connect everything to the Router's ports because of file sharing and network printer problems that would occur if part of your equipment is connected to the router and part of your equipment connected to the Ooma Home port. If there isn't enough router ports, people purchase and install a Switch connected to one of the Router's LAN ports. A Switch acts as a router port multiplier. I have two eight port switches installed in my home's LAN.
If you only have one computer or don't use file sharing, and don't have a networked printer, it doesn't matter where you connect your computer.
