Hopefully someone can help me with this unique problem I'm having. After activating, I hooked up the ooma (hub) to my dsl modem, them the pc into the hub, then phone into the hub. All was working fine until a couple days ago when I moved the hub to my wiring closet (to put it out of reach of little hands) keeping the pc connected to the hub but now wiring the landline to the ooma too.

The trouble seemed to start when I tried to call the landline from my cellphone to see if the phone connected to the ooma would ring. It didn't. Then my pc connection seemed really slow. I could still get ooma dial-tone but the hub didn't seem to recognize the landline at all.

In an attempt to 'fix' things I returned the hub to its original location next to the pc, only now the pc wouldn't connect to the internet at all!? After rebooting the pc, dsl modem, and hub I still could not get an IP from the hub.

After troubleshooting possible problems with the pc I decided to just remove the hub and reconnect to the dsl modem directly. Now I have an IP address and can connect to the internet, but pages seem to take way too long to load ( about 30 seconds ). I even reinstalled the OS thinking that would fix any changes made to the pc but pages still load soo slow.

Any suggestions on what to try next?

Can you describe in more detail what you did in this step?

To where on the Hub?

Sounds like in the beginning it was a simple case of your DSL signal getting squashed by connecting your landline (that carries it) to your hub (that basically disrupts it). If you are going to use a landline that carries DSL with any device other than a DSL modem, you must either use a DSL splitter (like the Wilcom PS15 - not the typical phone splitters you can buy at Radio Shack) or a microfilter. Otherwise the signal is attenuated and your Internet connection will be lost. Also, if you want to use landline integration (which I do not recommend) you need to have ooma provision your hub to allow it.

The question that I have now is why things are not back to normal with the PC connected directly to the modem. Did you leave anything connected to the phone line without a microfilter? Maybe one got lost in the shuffle when you moved things? There should NOT be one on the modem buy any phone must have one. After verifying the connections like I just noted, I would try turning off both the PC and the modem then turn the modem on and let it boot. Then turn on the PC. After things have connected, see how the speed is. You might want to run a speed test like and report back the results along with what your DSL speed is supposed to be.

To the wall port.

I do have a dsl splitter installed at the demarc. POTS on blue/wht DSL on orange/wht.

Your stats look good, and the speed reported by those stats are close to your subscribed rates - whichvoip's test typically under reports speed IMO. So I'm puzzled by the otherwise reduced speeds you are observing.

The reason I asked about how you had the landline connected is twofold. One was described in southsound's post about needing Ooma to provision landline integration via the wall port - and I agree that unless you have a very compelling need for this it will likely cause additional problems. The other reason I asked is if you were connecting it to the phone port by mistake and there was still telco voltage on the line, it could cause problems or in some cases even damage. From the article located here:, this quote:

First possible and most common set up: landline disconnected
You must make sure that your landline has been disconnected. Call your former phone company to confirm.
If the landline is still connected, the Ooma Telo may get damaged and it may void your warranty.
