[Speed Problem] Speed problem with Netgear DGND3300

Hi, please please respond is someone is familiar with this DSL modem speed issue:
Just installed a new modem router DGND3300 and internet access speed got decreased dramatically. (previously had Actiontec modem/routers that became unreliable and started dropping connections too often after years of work).

DGND3300 is connected with all light lite-up correctly and not warning of any kind showing. Internet is connected, just way too slow!!!
I was able consistently get a 2.5mb down speed with old Actiontec, and when switched to Netgear, downspeed is barely .5mb as measured with speedtest.net. Also speedtest.net shows a 24ms latency on Netgear, as opposed to 16ms latency for Actiontec. Upgraded Netgear to latest firmware and restarted numerously with no benefits. Netgear Tech suggested trying different MTU size to 1492, 1400, 1358 or 1300. -That made no real difference. However, when I disconnect Netgear and connect back my old Actiontec, I get consistent 2.5mb down,.5mb up speed and latency of only 16ms.

I know it is unlikely to be ATT or wiring issue, still, perhaps someone knows the secret.

4) Is your PPPoE login info (username & password) entered in the modem, in your router or do you use PPPoE software? -ppoe built in

5) Describe the lights on the modem when the trouble occurs. All light lite-up normally –no problem warnings

6) Confirm that you’ve checked to ensure that ALL devices plugged into the wall jacks serviced by your DSL phone number (except the DSL modem) have filters fitted. – Everyhting is plugged in and working

7) Confirm that you’ve powered off the modem and started it again and whether or not that made any changes with your problem. –Restarted numorously

What does the Actiontec show for attenuation, noise margin and sync rate? The Netgear is barely hanging on at 6.0dB so it must be dropping back from the 3.0Mbps sync rate. It sure seems like the problem is with the Netgear -- maybe it's time to get it warrantied.

Thank you so much for reply. I've enclosed actiontec data below.

Meanwhile I've found the device that causes Netgear (but not Actiontec) to drop internet speed - it is OOMA network telephone hub.
With ooma turned off, restarted Netgear picks up the speed.
So, now I am puzzled twice -should I replace both ooma hub and netgear router?, or just get another newer version of Actiontec to do the modem job.

Actiontec Status Data:
Speed (down/up): 3008/512

ATM QoS class: ubr

Near End CRC Errors (I/F): 0/2

Far End CRC Errors (I/F): 0/4

Near End RS FEC (I/F):0/34

Far End RS FEC (I/F): 0/0

SNR Margin (Downstream/Upstream): 11/20

Transmit Power (Downstream/Upstream):12/11

Attenuation (Downstream/Upstream): 47/55

OAM Statistics
Near End F4 Loop Back Count: 0

Near End F5 Loop Back Count: 0

Far End F4 Loop Back Count: 0

Far End F5 Loop Back Count: 1

Interesting that the Noise Margin picked up so much from before.

As far as the speed, I don't know much about ooma but I do recall seeing quite a few people having issues with how it's hooked up to their equipment. You might want to check out their forums, maybe someone there has this unit or has had a similar problem and solved it with a different hookup or some other workaround.
