OBi202 - Any advantage to hooking router to OBi?
PNS8:
Hi...
I have a similar requirement and tried connecting as above, but it does not work.
My setup is as follows:
* Motorola cable modem connecting to Comcast
* Obi202 device
* Wireless ADSL router with 4-port switch
I would like to connect the Internet port of the Obi202 to the single Ethernet port of the cable modem, so that the Obi202 acquires an IP address from there via DHCP, and then connect the LAN port of the Obi202 to the wireless ADSL router, so that whichever device connects to the router, either via a wired or wireless connection, gets an IP address via DHCP (from the Obi202) and is able to connect to the Internet.
I have tried numerous combinations as mentioned in this post, but the setup does not work.
For starters, the WAN status of the Obi202 never shows an IP address, subnet mask or other setting, which one would expect to be supplied by the cable modem's DHCP server.
Secondly, the setup does not work even if I connect a computer directly to the LAN port of the Obi202, let alone attaching the ADSL router to that port and then connecting a computer to the router.
Does anyone have a working setup like the above?
Thanks!

I tried to do this and it never did work for me.
Either the OBI could not route internet traffic (router), or you couldn't get to the OBI202 (bridge).

Thought maybe I could help some people out as I managed to set my obi QOS up
My set up is cable modem/router supplied by ISP, OBI202 with USB. and 4 port switch.
The Idea being that I can hook a couple computers up through the switch and do wireless on the usb. I haven't used the wireless yet, but did manage to get the QOS working with 3 computers I don't hook the computers into the router as that would defeat the QOS as all traffic needs to pass through it. Also running the obi in bridged mode did not seem to use the qos, I think because it did not direct the traffic as bridge mode does not use DHCP
First.. the qos on the obi is not enabled by defaults so that has to be checked in the setup and outbound bandwidth needed to be set.
The obi did not actually conflict with the router as it assigns a different subnet to its DHCP.
The router was 192.168.1.25 and the obi is 192.168.10.71
The online settings were not sufficient to set up my obi, to access the advanced options type 192.168.10.71 into the browser.
my conflicts were 2 fold as I had conflicts on IP addresses of my computer for reasons I'm not sure about but it seems that the switch and one of my computers were somehow occupying the same IP address, to get past this first thing, I reserved a DHCP address for each computer 192.168.10.102, 192.168.10.103 , etc.
The second issue was that I needed to forward ports as having two devices with DHCP creates 2 firewalls. So to forward from the router, in the router config, I forwarded to the obi at 192.168.1.71 then on the obi.. forward port# to computer at 192.168.10.102
Now if you are running a router after the obi, it would likely be easier to put it into bridged mode or buy a switch instead as it would be the same thing, however you can do a similar setup by changing the IP for the subnet of the router, say for example 192.168.20.1 or whatever you choose.. note that to log into your router afterwards, you will need to use this new IP address. Also, you will need to forward any needed ports in a similar fashion from the obi to the router and router to Computer or other device.
Not simple, but it is allot easier than some setups that I have done and works very well.
Also, for the posters original question about QOS on the obi vs ddwrt of the router. Both can work fine, but the obi is a lot simpler to set up. QOS can be a very touchy thing. Tomato is a little nicer to set up as it is easier to see what is going on with the graphs. The QOS on a router is allot more customizable
After having done both ways, this is a lot less hassle for me

Your ISP issues one IP address to your router. The router is then responsible for using NAT and it's own internal DHCP server to issue out local IP Addresses. That is where you get the different networks from. The router routes between the ISP and the local network.
To follow up, what I was trying to say is that when I connected a switch/hub to the modem, the cable company supplied a different IP address to each of the Obi and the router that connected to the switch. The router got its old IP address and the Obi got a number in a different IP segment. That appears to be a temporary IP address issued until the MAC address is assigned to the account at the cable company. As I remember, some ports worked but port 80 did not, on that temporary IP address. I did not do any other testing, but my next step would have been to see if any other ports worked and what speed I got to them.
