Cannot get my IP address and DNS servers

    Can anyone tell me why I cannot get my WAN information even when everything is set to DHCP, auto, Etc? I try releasing the settings(which aren't there) and renewing them with no luck. I hook-up my laptop directly to the cable modem and it works fine. What could be wrong with the router?

    Knowing some information about your setup would be useful i.e. cable/ADSL, ISP, router make/model, firmware version, etc.

    Did you power off and on the cable modem when switching from the PC to the router?

    Oh yeah that would be helpful : :shock: It is a WRV54G Router. I will try and power off the modem again, but I think I already tried that. Thanks for the help so far.

    Just came here looking for help with nearly the same problem: RV082 and Westell 6100 on Verizon Business DSL. DSL connection works fine when I connect the PC directly to the modem; RV082 doesn't see it (no WAN ip address; no access to Internet) when I add it to the mix. I have told the router that it is a PPPoE connection and supplied the credentials; have told both router and modem that the connection is "always on". Have soft and hard reset both devices (and rebooted the computer) to no avail. Router successfully passes traffic through to another LAN; it just won't work across the WAN port. Oh yeah... I have set it up as a dual-WAN because I do not need the DMZ for now. Anyone know how to fix this?

    If the Westell is doing the logging in then you should have the RV set to Obtain an IP automatically rather than PPPoE.

    I tried it that way first, but switched it when it wouldn't work. I'll try again, though...

    Nope; still no joy. I switched the router config to "acquire an IP address automatically" on the WAN1 link, but it's still dead. When I go to Log -> Statistics, the WAN1 link shows "Disconnected" with an address of "0.0.0.0", while the WAN2 link (not used at this time) shows "Down". This is the 1.1.6.14 firmware, if that makes any difference.

    Wrong or faulty cable between the two :unsure:

    Don't think so; I already swapped it out to be sure. The Status screen shows a green "icon" on the WAN1 port when everything is in place; it goes black (and the Statistics screen shows both WAN ports as "Down") when I remove the cable. I have been removing it often in order to connect the modem to a dedicated computer so I can go on-line (and post these questions, for example), then putting it back to test yet another setting or configuration option in the intended environment. The router is correctly handling traffic between our LAN and another WAN (on the other side of a Cisco router), seems to know that the modem is there (but not its status), and the modem itself works. I'll be at the office in an hour; I'll swap the Ethernet cable again, try the WAN2 port, and whatever else comes to mind until I run out of ideas and come back here...

    I was thinking more of it requiring a crossover cable and a straight through being used, although it sounds like this isn't the case.

    this is because router uses NAT/Firewall etc, the cablemodem wont be.
