Large reduction in bandwidth when ObiHai 202 is connected.

1. I find it difficult to come up with any explanation of how a device with a 100 Mbit/s ethernet port could itself be generating enough traffic to cause changes of more than 600 Mbit/s in download speed and more than 100 Mbit/s in upload speed. I would suggest a complete look at your network topology and IP address settings of all devices on your network.
2. Regrettably the response from Obihai support is just another demonstration of its unworthiness of the name. Opening ports is a different thing from forwarding them. While virtually every home router can do the latter, none of the dozens I have examined have controls for the former. And anyway whether those Obi-specific ports are open or not would have no impact on your speed tests using a computer.

My home network setup is pretty common. GF fiber with a Netgear Nighthawk X10 R9000 router (about 5 weeks old with latest firmware applied. Likely one of the best performing routers for home use). Cat 6 cable from router to Office which has one drop. The cable from drop plugs into a Netgear G5605V4 unmanaged (dumb) switch. My PC plugs into that dumb switch and also the Obi. I have had no network or bandwidth issues until I purchased the Obi last week and plugged it into the dumb switch. Bandwidth returns to normal if Obi is unplugged?
I tried several things but here are ones I recall:
1. Using different patch cords
2. Moving to other switch ports
3. By passing dumb switch (using Obi LAN) which would not have worked anyway because of 30Mbps limit.
4. Toying with the ports per Obi Support
5. Disabling SIP ALG on Router
I will experiment with it later as time permits.
Yes, Obi support was very disappointing. Maybe, I did not get a good support person? It appears the members on this forum are more knowledgable than their support.
Time_Lord:
Just because you have a gig interface available to you doesn't mean that the device is capable of forwarding packets at a 1Gb/s rate.
I suspect that the Obi 202 is simply not capable of forwarding packets at line rate and would suggest you simply put the Obi behind your existing router. Will you loose the prioritization that the Obi provides yes but....
1) a voice call only uses about 85Kb/s
2) unless you are running your internet connection at 100% capacity you won't have a problem
3) ISP's typically ignore prioritization (QoS) on anything that they do not assign the value to
4) even if your ISP honors your QoS markings, the next ISP will ignore them anyway
The time that the Obi 202's router capability is worth while is if you have an unusually slow connection (eg DSL), otherwise it won't keep up with the data throughput.

eaglemaster:
i am also concern about the bandwidth/usage as i am on early stage of moving to Obi from Vonage as currently with vonage i had assign it a static IP and also used port forwarding and also activated DMZ in my router the port numbers were given by customer service , can anyone include what port numbers should i use when activating port forwarding for the static obi device?

Stop being concerned. Whatever the cause behind the original post in this thread, it is not experienced by the vast majority of OBi users.
Port forwarding is rarely needed with OBi devices on home networks*. And whether a device (any device not just an OBi or Vonage) needs ports forwarded to it is completely independent of static or dynamic IP address.
(* Corporate networks may be a different kettle of fish, as they frequently have firewalls to block everything except what is officially sanctioned and needed for business purposes.)
