I had my setup like this to take advantage of QOS and ensure VOIP had precedence.
CableModem --> Obi202 --> NetgearRouter --> PC and other stuff
The cable company has been increasing speeds and I went from 12mbs to 24mbs, but a local guy told me I should be getting much better. The modem I had should be fine up to 50mbs but I upgraded it anyway. No change.
Then I checked the OBI config for speed of the internet side and it was already set for 100mbs.
On a hunch, I hooked my PC directly to the cable modem and ran a quick speed test. 94mbs!!!
I inserted the router as the first device, then hooked the OBI to the router and still saw 94mbs on the PC.
For some reason, the Obi was not allowing me full throughput. It may be some config I missed, but since the router is seeing the massive increase in speed, I see no reason to have to put the Obi first anymore to ensure voice bandwidth.
I may just leave well-enough alone.
