    I was wondering if anyone could help me with a home networking issue...

    I've connected my Dlink DSL 604+ router to my NTL broadband cable modem.
    Most of the settings are on default.

    I have two computers a desktop and a laptop. want to be able to connect them both, wireless for the laptop.

    At the moment I am trying to get the wireless to work, as a direct wired connection works. I can connect wirelessly to the router but can't connect to the internet.
    When I have the wired and wireless connections both on the laptop heres what I get :-

    Wireless LAN adapter Wireless Network Connection:

    I'm no networking expert but many things hit me as strange. Is far as I know the router subnet should be 192.168.0.x (mask 255.255.255.0) The wireless settings therefore look more correct but don't work. The wired settings look a bit weird but they work...

    thanks

    like you, im no expert, but im wondering why the wired ethernet adapter does not have a private IP address (192.168 or other).

    Is NAT swithched on , on the router? If not then you wouldnt be able to connect with the laptop because of its private IP.

    Also, the default gateway for the wired ethernet should be the local IP of the router. (I think).

    My first thought is that this is not the right router for you.

    You say you are NTL broadband *cable*. Is this really cable, and not ADSL?

    I *assume* that you are connecting one of the 4 ethernet ports to the cable modem. If that is the case then you are just connecting to the hub part, not the router! So you can only use 1 machine at a time with an ethernet connection.

    You need to buy a *cable* router, which will have a RJ45 socket instead of the RJ11 to connect to the cable modem.

    Yes I had that suspicion because I don't have a WAN port.

    I used to have ADSL in my last place, hence the ADSL wireless router, wanted to figure if there was any way I could make it work for wireless.
    Now I have moved back to my parents temporarily and they have cable so just plugged it in for kicks.

    Is there anything you'd reccomend ? I've heard people talking about building CCNA labs, should I maybe buy a couple bits of kit in case I want to do CCNA in future or just buy a cheap belkin or linksys cable router ?

    thanks

    There are plenty of cable router plus wifi units around for about £35. For casual use I see no point in paying over the odds for a well-known brand. These days they are all using one of the limited number of chipsets!

    Whats the current thinking on these ? Is the spec stable now ? Are they worth the extra cost? My laptops got a new intel wireless n card in it...

    It is a bit early for 'n' devices IMHO. And the speed you get will depend hugely on the signal path and any obstructions.

    What is 192.168.4.100? You are using this for DNS just now however your default gateway is 192.168.0.1 which is on a different subnet. That may be the issue.

    I assume you can configure a LAN subnet in the D-Link? If so configure a scope for the 192.168.0.x subnet and make 192.168.0.1 the DNS. (I assume this is the IP of the D-Link). make sure NAT is enabled in the D-link or the NTL modem.

    That IP is for one of NTL's DNS servers. A DNS server does not *have* to be on the local network. It is just that many ADSL routers cache the DNS to make life easier.

    <Cough> The point here is that dave wasn't actualy using the router part, as it is bound up with the ADSL modem and can't be separated! So this unit can't be used as a router.

    I wouldn't say that! :p

    It seems to be a fairly common mistake judging from the questions I get asked at computer fairs.

    Agreed, most routers I configure generally have the DNS pointing at the ISPs DNS servers and the clients point at the router for DNS. I guess it acts as a 'forwarder'.

    Having read over this thread again, buy a all in one cable router with wireless :biggrin
