Strong wireless signal but no internet

    Hi guys,

    I've read through the sticky on wireless but I am still lost!

    I have just signed up with NTL 3mb broadband. So I have the NTL modem and the whole thing works fine when I plug the cable directly into my laptop.

    I have a Netgear router which I previously used with Irish Broadband at another address. I want to use this router with NTL now. So I plug the cable from the modem into the router and turn on my laptop. On my laptop I can see that I am connected to the wireless network and the signal strenght is excellent.

    But when I try to connect to the internet (firefox) I cannot connect. Do I need to do something with IP addresses? Is it the router or the NTL modem that has an IP address? I'm not very techy but surely I'm almost there with this- is there just something simple I'm not doing?

    Thanks in advance.

    Is the router set to collect an address by DHCP from the UPC modem, or is it set for static addresses as some IBB products use?

    sounds like an ip address problem alright. Either your laptop is set to use a dynamic address and dhcp is turned off on the router, or the laptop has a static ip address and the router is using dhcp and has already asigned the address to another computer

    IBB usually set the IP address of the (Netgear) router manually . The address they set won't work on anyone elses network


    Try this

    Get a command box open :

    Click on "Start" ---> "Run" type in cmd

    type in ipconfig

    take note of the number after " Default Gateway " ........

    ( it will be something like 192.168. something )


    type that number into the addressbar of your browser

    It might look for a password.

    If you look on the bottom of the router itself , the password is written on the little sticker.

    Look around for " WAN settings " or something similar


    It will probably be set to " Manual" and be something like " 87.192. something"

    Set it to " DHCP" ( Automatic ) and apply/save it.

    Before you log out of the router , have a look around there for

    " MAC Spoofing "

    and note where it is , you might need it if this doesn't work

    If it doesn't work , reboot the NTL modem and reboot the Netgear


    If it still doesn't work ,

    Click on "Start" ---> "Run" type in cmd

    type in ipconfig /all

    Look around for

    " Physical Address " under " Ethernet"

    and make a note of it

    (It will be something like 00-06-7e-4f-8e-9f )


    Log into the router again , find the

    " MAC spoofing " box , and put in the "Physical Address" number you made a note of

    Save/apply it , give it a few minutes , if it doesn't work , reboot the whole lot again
