ubuntu - Configuring Wireless ADSL 2+ router for static IP

    I have the following

    1. Binatone DT845W wirless ADSL2+ router
    2. An ethernet port with static ip which provides access to the internet

    Problem: I want to configure internet access via the router, so that I can connect multiple devices to the internet via the router. I can connect directly using my laptop to the ethernet port (2). The laptop runs Ubuntu 10.04. The ISP has provided a static ip, subnet, gateway and dns server addresses.

    I am unable to configure the ADSL router. Earlier I was using it seamlessly with a incoming DSL connection. I have no idea how to configure it using the incoming ethernet port.

    EDIT

    The router has one pot for DSL, four ethernet ports and a wireless antenna (Nothing specifically like a WAN port). It has indicator lights for the DSL, WAN, Ethernet port, Power and Internet. When I used to connect via the DSL line, the DSL, WAN and Internet lights would flicker. However, now only the WAN light does so, no DSL and no Internet lights!! :(

    I tried connecting the input ethernet to one of the lan ports of the router, put in the configurations for static ip in the router. Still the status displays as 'Not Connected. ADSL Link Failure'.

    Can this device even do what I want it to do? Or does it need a DSL input to work?? If this device is not capable of doing such a thing, can somebody please point out a device which can do this (both is even better!!).

    Can somebody please please help me out??

    I will be eternally grateful!!!

    networking - Connecting a ADSL router to a wireless router. What am I doing wrong?
  • Eduardo Molteni

    What is the correct way to do it? This are the steps I have taken:

    1. Disable DHCP in Wireless router
    2. Setup a fixed IP (192.168.1.2) and telling that the default Gateway is 192.168.1.1 (the ADSL router)
    3. Plugged the Ethernet cable from the ADSL router to the "Internet" port in the wireless router.

    It does not work.

    Got a little complicated whilst writing this - 1 refers to your modem, 2 refers to your wireless router.

    This is one thing I hate doing as it can change based on device manufacturer and features. Personally, if you can upgrade 1 and 2 and just have one device, you will be better off.

    For a start, if your 2 actually supports this e.g. has an Ethernet WAN port instead of a smaller telephone line adapter, you may not even have to disable DHCP anywhere - simply make sure the 1 works (connect it up to one pc) and if it does, plug it in to to the 2, and then it should "just work" - if it doesn't, your 1 is more likely to be an actual router (just with one port).

    so, if 1 is actually a router instead of a modem, I would recommend that you see if you can change the mode of 2 and basically disable all routing and change it to an access point, this will then do all the DHCP and everything else at 1 whilst just providing an access point to wired and wireless devices - by far the best way. (After changing this, you may have to first manually set the ip of 2, this will mean that all devices are pingable and accessible on your network and the easiest to manage.

    step by step - you seem to have done some of this already, but this certainly works

    1. go to the wireless router setup and turn off its dhcp server and set up a fixed ip address to it.
    2. connect the wired router and the wireless router - lan connection to lan connection (as odd as it sounds)
    3. check if you can access the wireless router from a box connected to the wired router 4) if so test the wired connection, then the wireless.

    This worked in a similar setup for me and others

    here is a good article, 4 ways to do that. It is very easy:

    It depends how your provider initially set this up and how you want to set it up.

    The setup you allude to is where the ADSL modem is connecting to your provider as well as routing and taking care of DHCP, etc.

    A preferred setup is where the ADSL modem simply handles connecting to your provider. Often this means the router has to be configured to do PPPoE, authenticating to the provider via the modem. The router can then handle DHCP, NAT, filtering, port forwarding, etc. Sometimes this setup requires setting the modem to some sort of pass through mode.

    Post your exact device information for better help.

  • Arjan

    Your instructions are correct, but you'll also want to disable NAT on the modem.

    You may be having an IP conflict. Did you release your DHCP IPs from your client machines before installing your wireless router? Maybe you assigned your wireless router a 192.168.x.x IP that was in use by another device.

  • Eduardo Molteni

    Tried again from zero and works right away (The magic of PCs :)

    Things I did:

    1. Leave the IP of the Wireless router in automatic
    2. Change the internal IP to 192.168.5.1 (I think here was my mistake last time)
    3. Leave DHCP ON and starting with IPs 192.168.5.100
    4. Presto! All works like a charm in 5 minutes.

    Thanks all for answers!
