DW7000 does not like router

Posted on 2006-05-06
Last Modified: 2013-11-29
Until yesterday I had my D-Link DI-634 Wireless Router connected to a DW7000 DirecWay connection. All running fine. Now I have a DW7000 and I just can't get it working. It looks as if the main difference between the configurations of the two modems is, that my DW7000 hat NAT enabled. Is there a way for the user to change this, or do I have to call the experts who installed it? What else could cause the problem? When I try to run the installation procedure for the router, I get the information that both, the DW7000 and the D-link act like routers and I should change the address ( of the DW7000. How can I do that?

    The default subnet of the D-Link DI-634 is 192.168.0.x
    If the Modem has NAT enabled and using a LAN subnet of 192.168.0.x you will have to change one or the other. The LAN and WAN of a router, the DI-634, need to be on different subnets. Try using 192.168.2.x for the DI-634's LAN configuration.
    On the other hand if on the modem NAT is turned off, and it is in bridge mode, you can use any subnet but the WAN page of the DI-634 must be configured with the ISP's connection information. Bridge mode effectively disables the modems router capabilities. (the latter configuration would be my preference)

    I have changed the router's address to but still without result. It does not recogize the DW7000. How do I turn off the NAT mode on the DW7000?

    I am little bit confused here.
    Is the dw7000 a router? from what i know, it is not?
    One quick way is to run the dw 7000 directly to a PC.
    Make sure that the PC can get out to the @ and then introduce the wirless LAN....for troubleshooting sake.
    the dw7000 config should be like the other ones...

    Is the WAN page of the DI-634 configured for DHCP connection?
    Does the connection work properly with a cable if you connect directly from a PC to the DW7000?

    As for switching it off I found a manual and it doesn't seem to be an option, at least not user configurable. I did find this; "network address translation (NAT), the firewall, and dynamic host configuration protocol (DHCP) are enabled or disabled depending on the service offering purchased by the customer."

    what level of service are u running on DW7000, you cannot change settings on DW modems, unless you change our service or pay for a segment to be setup with Public IP, If you have a basic domestic connection your modem is doing NAT and DHCP. scenarios:

    1.- level1 service: your modem is probably on and set manually to router and test

    2.- Are you on a 67.45.189.**/252 network wich means that static IP could only be assign to 1 device. if you're on static IP then check the netmask to see how many devices could connect.

    using 1 NATovet another NAT wouldn't hurt unless you'r using special software that requires special connections.

    The MAIN thing here is knowing the Setup you need to have to connect to service. Info you must have!!

    Any extra comments would help on helping you..

    CKWT: It looks as if I have accidentally changed from static to NAT together with the modem.
    Here some of the DW7000 info:

    Site ID: 37897301
    Serial Number:
    Software Date: Dec 13 2005, 13:57:57
    Software Release:
    LAN1 IP Address:
    LAN1 Subnet Mask:
    NAT IP Address:
    NAT Subnet Mask:
    Transmit Radio Name: OSIRIS
    Transmit Radio Part Number: 1035817-0001
    Transmit Radio Wattage: 2 Watt
    Wideband Support: Yes
    Extended Band Support: Yes
    Frequency Band: Ku
    Transmit Path: Satellite
    Outroute: Primary
    Longitude: 89 West
    Receive Frequency: 1390 MHz
    Receive Symbol Rate: 30 Msps
    Receive Polarization: Horizontal
    Transmit Polarization: Horizontal
    22KHz Tone: Off
    Router Address:
    NAT: Enabled
    DHCP: Enabled
    Firewall: Disabled (from NOC)
    Turbo Page: Enabled

    For the router I can give you the following:

    MAC Address : 00:15:E9:5D:6F:6C  
    IP Address :  
    Subnet Mask :  
    DHCP Server : Enabled  


    MAC Address : 00:15:E9:5D:6F:6D  
    Connection : DHCP Client Connected  
    Connection Up Time : 0 day(s), 0:05:51  
    IP Address :  
    Subnet Mask :  
    Default Gateway :  
    Primary DNS Server :  
    Secondary DNS Server :  
    If I change the LAN address to, I get the message "Lan subnet conflicts with WAN subnet". Thats it.

    My old static address was

    Will I have to go back to static address (which costs me 10 US$ more) or is there a solution with NAT?

    Accepted Solution

    there is a solution with NAT, I said WAN to to match from DW...

    Another thing is what do u mean by the router is not reading the DW, the DW is NAT so it's DHCP itself, u only need to keep everything as is...

    your DHCP does not assign an IP to router assign a static to WAN.

    DW>   WAN                    LAN           ------> Laptop

    Hope it helps, and if you have everything the way you posted and looks alike with design.. tell us again what your problem is?

    CKWT: Thanks for the diagram. Thats what I had guessed too but apparently I had messed-up the routers configuration and it just did not want to do its job. So I used the paper clip solution: A push on the reset button and a moment later nearly everything was connected (BroadBand phone needed additional intervention) and the router has configured more or less what you proposed, automatically. Next time I will RESET before I start re-configurating...
