I tried to connect the Ooma Hub to the internet via a Netgear WNCE2001 Wifi Internet Adapter (connects via an ethernet cable to the Ooma hub), but the Ooma can't call out it could only receive calls. The Ooma works fine with a DSL internet connection, but when I connect it using the Netgear Wifi adapter (using a wireless hotspot signal to provide internet via ethernet cable) at speeds faster than my DSL, the Ooma just pauses indefinitely and won't dial out. The internet from the wifi adapter works great when passed thru the Hub to the router, so I know the internet connection is working. I am just wondering if there are generally any issues when using Ooma from a wireless internet sources. Should I have to change any settings?

Looked into this some more. Here is what I'd do.

Look at the manual: ... 4Sep10.pdf

Go into Device Status Screen and make sure the DHCP server is Off.

Under the LAN Port, see if MAC address is your Ooma's MAC address (modem port MAC is one higher than what's printed on bottom of Ooma) and Ooma's IP address is what your router says your Ooma's IP should be (router usually can list out connected devices along with MAC addresses).

In the below link, I talk about some of the devices you can use to provide ethernet devices internet. If this Netgear adapter doesn't work out for you, I'd recommend D-Link DHP-303 (powerline ethernet) or the D-Link DAP-1522 (wireless bridge just like the Netgear device you have).

I had a Netgear Universal Wifi Range Extender WN2000RPT before but finally got rid of it because no matter what I tried (upgraded firmware, reset, reconfigured etc), the WN2000RPT would turn its own DHCP server on (after a few days; just chnaged the "DHCP off" to "DHCP on" all by itself) assigning connected devices different IP than what my router would assign (I have all my devices with router DHCP reserved IP addresses).

Thanks. I will try the suggstions provided. I do find it odd that I can receive calls, but cannot call out using Ooma. The wifi connection between the Netgear adapter and the internet hotspot is fairly solid. However, I have noticed that the internet hotpspot connection >2 Mbps, but choppy.

I was able to confirm that Netgear wifi adapter LAN Settings for the DHCP was off and the wifi adapter works well with Ooma for outgoing and incoming calls when used with with a strong Wifi and wired internet connection. However, one thing that I noticed is when Ooma is connected to the wifi adapter using a wireless wifi internet hotspot, the upload speed is very slow ~ .03 mbps, despite good download speeds. Could the slow upload speed and decent download speed result in Ooma being unable to make outgoing calls, but accept incoming calls? I can't seem to find any other causes.

jw530, what is the source of your wifi? DSL modem router combo?
That .03 is about 1/4 of what Ooma needs (.13).
Is your router configurable? Try turning to non default wifi channel (1, 3, or 11) and turning channel bonding off (use only 20 MHz) to see if your wifi performance improves.

Just to clarify the netgear wirless wifi adapter worked with Ooma when the adapter was being fed a wifi signal from my wireless router, which was given internet from DSL with a speed of .63 mbps down/.38 mbps up. The netgear wirless wifi adapter couldn't make calls with Ooma when the adapter was being fed a wifi signal from my wireless hotpsot, which receives internet from Wimax towers with a speed 1-2 mbps down/.03-.11 mbps up. I have heard that Vonage and Skype can work with speeds as low as 30 kbps, but I suppose that Ooma uses a higher bandwidth Codec. So it appears that the hotspot doesn't clear the minimum necessary for Ooma, and that might just be limitation of Wimax.
