Why is my speed slow with an Ooma?

Some users have mentioned that their internet is slow using an Ooma. We performed a speed test and found the following using an Ooma Telo.

Ooma Telo allows 2 different connection topology –

• Topology 1:  modem – Portal – Ooma. This the default topology described in Ooma quick-start-guide. In this topology, the traffic goes through Portal, and Portal controls the overall traffic flow
• Topology 2: modem – Ooma – Portal. This is the alternative topology, in which all the traffic goes through Ooma, and Ooma controls the traffic flow and prioritization of traffic. The advantage of this topology is Ooma can reserve/prioritize bandwidth for their HD voice quality. However, during the test, we found the Ooma is way too aggressive in reservation for voice traffic, and caused significant bandwidth decrease for other traffic.

The following lists the Ookla speed test result on an iPhone 6s (2x2ac) with Portal on a 30/5 (down/up) connection - 

As you can see, in topology 2 (Ooma is sitting between modem and Portal), Ooma is aggressively control and tune down the other traffic, to reserve abundant headroom for his HD voice quality. 

Our suggestion is to put Ooma behind the Portal (topology 1), and let Portal to control the traffic flow. If you continue to put Ooma before the Portal, please be aware of the bandwidth limitation issues described above.
