|  Question: DSL Modem Modes/Access to GUI
Hi, all. I'm new to DSL and am hoping to get help in understanding the operating modes for my DSL modem (D-Link 2320-B).
1. Am I correct in assuming the modem came from DSL Extreme pre-configured in "bridge mode"? I assume this is true because (a) I did not have to switch it to bridge mode (b) I had to set my router up to perform the PPP negotiation and (c) the modem appears to be operating as a Layer 1/2 device, i.e. it does not respond to attempts to access it at a 192.168.xxx.yyy IP address and therefore I conclude that it has no IP address and is invisible to the network layer (i.e., it's a bridge). Unless this is an address mask issue.
2. Since there's no IP address, I apparently have no access to the modem's config interface, i.e. its GUI. Is there in fact no way for me to talk to the modem to monitor signal power levels, s/n ratios, etc.?
3. Is the only way to gain access to the GUI a push of the reset button, to take the modem out of bridge mode (but break the network connection)?
4. Am I constrained to always operate the modem in bridge mode? Or if I instead set the modem up to perform the PPP negotiation, presumably it could use PPP to obtain a WAN IP address, and it would then also have a LAN IP address and would serve a different LAN IP address to my router via DHCP. Then would I have access the the modem's GUI during normal operation? (This analagous to what my cable modem used to do.) Is this mode even feasible with the "dynamic IP/PPPoE" connection provided by DSL Extreme? Is there any disadvantage to operating in this mode?
Thanks for any enlightenment. | |

Welcome to DSL & DSL Extreme!
You are correct, the modem that we send out comes in bridge mode. We find this is the easiest way to setup a client as a majority of our clients are on DHCP based connections and or have a router that can do the PPPoE authentication if needed. The D-Link 2320B does have a GUI interface that you can access. In order to access it, you must set your computer to an IP address on the same subnet as the modem. Though we have a custom / slightly firmware on the modem I believe there are setup instructions on the D-Link website that you can reference if you would like to login. »www.dlink.com/products/?pid=554
Assuming you are on a PPPoE based connection, you can use the D-Link to do your authentication in what is sometimes referred to as "half-bridge" mode. It will pass through the WAN IP address to your computer.

Thanks for the reply, George. So to further clarify this for me...
You say:
"The D-Link 2320B does have a GUI interface that you can access. In order to access it, you must set your computer to an IP address on the same subnet as the modem."
Right, I knew that, and so actually before I ever even connected the 2320B to a DSL line or my router, I connected it via Ethernet to my laptop in an attempt to see the modem's GUI. The D-Link user guide says that the 2320B's default IP is 192.168.1.1, so I took my laptop's Ethernet connection out of the "get IP address automatically" mode and instead specified "use IP address 192.168.1.2," thus I think satisfying the same-subnet requirement. Alas, I could not access the modem's GUI login this way. Is this because the modem arrived in bridge mode and thus had no LAN IP address? If I had forced the modem out of bridge mode, would I have succeeded in reaching the GUI? BTW, at that point I didn't want to screw up anything so I just hooked the laptop, router, modem, and DSL line "normally," restored the laptop's Ethernet connection to DHCP mode, and proceeded with normal setup, which went fine. A subsequent attempt to force my laptop back to 192.168.1.2 while connected behind the router (whose DHCP range is 192.168.0.40 to 192.168.0.99) also failed to reach the modem's GUI.
I guess my bottom line question is, is it possible to set the router and modem up such that while the DSL connection is up and operating normally, I can also have access to the modem's GUI? If so, how do I do it?
Sorry if you answered this already and I just am too thick to recognize the answer. | |

| Hi mhguy -
That should be the correct IP address. Did you set the gateway address to 192.168.1.1 as well. My assumption is that you may have missed that which is why you couldn't get to the interface. After you set that in your browser go to 192.168.1.1 and you should be able to get to the interface.
Let me know if that works for you.
Thanks
