Obi202 Throughput speed issue

[Lavarock7]

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.

The OBi202 throughput in Router Mode is 30Mbps max.  This could/would be your bottleneck if the OBi is in line of your WAN link.

I'd make sure it is in Bridge Mode:

LAN Settings - LAN Settings::OperationMode = Bridge ;disable the router.

And keep it connected to your router LAN switch to protect it from the Internet.

You should not see any QoS issues unless you have excessive streaming LAN traffic... doubtful.

A SIP session requires ~85Kbs more or less depending on encoding.  Multiply that a few times for simultaneous sessions to know your required VoIP capacity... still less than a minimal 1Mbps upload speed.

I wouldn't use the Obi 202 in router mode.  I'd hook the Obi to the Netgear, and let the Netgear hand out DHCP addresses.
