Ok, so you know how to change the mac address on the router? If you use a linksys, there should be a tab called mac addr clone, or something along those lines. This is where you enter the mac address that you want to appear on the wan. And once it's changed, leave it for as long as you want the ip. When you want to change your ip again, change the mac by 1 character, as many new ips as you want Just a side note, you can only enter valid hex characters in that field, so 0-9, and A-f ie, 00:A7:09:FF:3D:11 Also, from your connection details, it shows that the lease time is 4 days. So theoretically, after 4 days of using a different mac address, you should be able to revert back to your original one, and get a different ip altogether. cheers
