NTL + Linksys wrt54gs v6
 

Hello there,

First off i would like to start by saying i am a pretty low end user. AKA complete noob pls remember that if u post :d

Ok my isp is NTL i have the 2mb package with the ambit 51000 cable modem, currently using it with my Linksys wrt54gs v6 router.

Before i started using my router i used to be able to change my public ip address (i think this is my WAN IP?) simply by doing an ipconfig /release ipconfig /renew.

That still works for me, but not when i am using my linksys router, i continually get assigned the same ip. If you guys know how i can get a new ip for my router i would be very grateful!

2 hours of google searching and the only answer i could find which was relevant was to turn off my router and modem, then turn on the modem letting it fully boot, then turn on the router. Which was supposed to give me a new public IP address, but it didnt work. I tried tinkering with my router's settings but i didnt have a clue what i was doing and ended up having to restore factory defaults.

Your router provides the IP address to all of the devices connected to it - unless you have specifically set up static addressing. So if you ipconfig release/renew etc all that you are doing is releasing and renewing from the router and since the IP address you have just released is available for reuse, you'll likely get the same one again.

My Linksys, out of the box, is set to allocate addresses in the range 192.168.1.100 to 192.168.1.149 (a 50 address range). Yours may well be the same and so the address you see for the PC after the ipconfig should be in that range.

VM provides an IP address for the cable connection - and if you plug your PC into the cable modem then that is the IP address that your PC will get. Once you plug in your router, it takes that IP address and hides the IP addresses that it gives to your connected kit from the outside world.

How to change your public IP address? All that I have seen are suggestions to power off the modem for some period of time in the hope that during that time your original IP address gets re-allocated - so when you power up you get a new one. That's on the old Telewest side - it may be on the NTL side you can request one via the ipconfig route - if so the router has a facility to DHCP release and DHCP renew in the "Status" "Router" screen.

Hope this helps.

You want to be cloning a MAC address in the router, change that and power off the modem, and the router, then power them both on in order. The modem will think it's connected to something different, and as such you'll get given a different IP address.
