Large reduction in bandwidth when ObiHai 202 is connected.
GWRider:
I recently installed ObiHai 202 and configured it for GV use per Obi's instructions. Everything appears to be working except I noticed that my internet performance became extremely slow. I went to different sites to check my bandwidth and noticed a whopping 80 to 90 percent reduction. I understood a decrease was to be expected but not anything like this?
When I unplug the Obi device or disconnect the network drop the bandwidth returns to normal.
For example, my normal fiber bandwidth is fairly symmetrical at approx. 800 to 900 Mbps. When Obi is connected my download consistently drops to approx. 115 Mbps and upload reduced to approx. 670 Mbps?
I have one CAT 6 drop into my home office, so I am using an umanaged Netgear GS605V4 (dumb) switch to plugin the Obi and my PC. I tried eliminating this switch and plugging the drop directly into the Obi then going to the PC. This resulted in even lower bandwidth to around 20 to 30 Mbps (the Obi device is on the latest firmware).
The one thing that stands out is that the above switch shows green for 1gb connections and orange for 10 to 100mb connections. The Obi connection shows orange. It is my understanding the network will only be as fast as the slowest aspect which in this case appears to be the Obi device? Any ideas or if there is something I am missing?

I believe I figured out what is going on. I am not sure if anyone noticed this before but if you log on the ObiTalk.com site it will drastically reduce the available bandwidth. I did several cycles of logging on and off. Each time I would log on and performed a speed test it would result in an 80-90% drop (approx. 60-100Mbs). As soon as I logged off and repeat the speed test it would return to normal (approx. 800-900Mbps).

The OBi202 contains a router between its two ethernet jacks. Although that can be switched off (putting it into "bridge mode") the default is router mode and it is known that the maximum throughput is around 30 Mbit/s. That should be of no consequence if you are not using the LAN socket on the 202. However, if you do use the LAN socket, any device or devices fed from that will be impacted as you already noticed - ".

I have no explanation for your other observations but do wonder if the reductions are real or due to some "defect" in the measurement method which is invoked or exacerbated under certain conditions.

No difference in up or download speed when running a speed test before or after visting the OBiTalk web site. Any problems are likely attributed to user equipment or PEBCAK issue.

Thanks for the info. as that explains the 30 Mbps max when I tried using the LAN port. As for the ObiTalk site in my earlier post, it appears coincidental as the problem returned today without being logged into their site.
Also, I heard back from Obi support and they said to open up the following on my router which I already tried. :(
