I installed my Ooma by directly connecting it to my cable modem and then from Ooma to my router and on to my PC as was the preferred method in the materials I'd read.

I recently had my Internet speed increased but I failed to notice an increase in speed. When troubleshooting it with the Tech staff from my ISP they had me disconnect Ooma and connect my computer directly to the cable modem. I did and the speed increased by a factor of 10. I next connected my router to the cable modem and my PC to the router. No drop off in speed. Next I reconnected everything as it had been and I lost 90% of my Internet speed.

Apparently, Ooma is reducing the speed of my Internet connection but I am at a loss to understand why. I now have Ooma wired from my router instead of directly connected to my modem.

Can you explain why the slow down in Internet speed when I connected Ooma in the preferred manner?

You didn't connect to Ooma's configuration page and set the QOS values to match your internet speed. The default is for slow speed DSL.

jrb451:
Setting Quality of Service:
Use this step ONLY if your Ooma setup is Modem-Ooma-Router:
Access the Ooma Setup Advanced page. Under Quality of Service set both the Upstream Internet speed and Down Stream Internet speed to 80% of the measured speeds as measured by http://www.speedtest.net/. Click on Update. Reboot your Ooma Device. Then test making and receiving calls. You may have to adjust these speed slightly up or down to obain the best conditons.

The other thing that you could do is just connect your setup Modem-Router-Ooma. I have mine setup that way and it works fine. Just a few people have Quality of Service problems connected this way, that can be taken care of with small adjustments of the router or Ooma.

Try temporarily connecting Modem-Ooma-Computer.
Try using a network cable connected from the Ooma Telo Home port to the wired LAN port of a computer. Temporarily turn off Wi-Fi in the computer, if Wi-Fi is turned on in the computer. reboot the computer. Type http://172.27.25.1 in the computer browser window.

If that doesn't work:

Try using Firefox or Internet Explorer to access Ooma Setup.

Temporarily turn off Internet security and virus protection and try.


Adjusting the Quality of service may help the "metallic" sound, but most people have had better success contacting Ooma Customer Service and having a second level person make adjustments on their side.

I am having the same problem as you. I recently went to 50mb internet speed and my Ooma kills most of that bandwidth. So I moved it to the router instead of the 'in between' setup and it's now back to 52mb down.

Problem is now I can't make outgoing calls. I am trying to get that figured out now. Recv is fine, outgoing is not happening.

Did you compeletely shut down and reboot everything in sequence (modem-router-ooma) after you changed your setup? Did you change OOMA setup to use built in MAC address? I'm just starting with the basics that may solve your issues if you've not done this already.

SOLVED: I had the same issue when I picked up the phone our Internet would completely freeze. I contacted Ooma support who suggested I change from their preferred configuration from modem-Ooma-router to modem-router-Ooma, instead, I did some more research and found that (http://lifehacker.com/326543/ensure-a-f ... ou-need-it) setting the QOS in the Ooma Telo (http://setup.ooma.com/home.lp (go to advanced)) to 85% of our speedtest.net results for both upload and download speeds solved the issue completely, in fact when I'm on the phone now, speedtest.net results are identical to when I'm not on the phone!! I am now very very happy with my Ooma Telo :D
