Problem is, it changes my IP address but only slightly.
That's right. There's no way around that, other than to
change the internet provider.
Your external IP is assigned by the ISP. If you somehow managed to change it on your router to whatever IP you wanted then your Internet connection would stop working. Your IP must remain within the subnet assigned to your area by your ISP, and it must not be an IP assigned to someone else (duplicates aren't allowed).
Anyway, cloning the MAC address fools the ISP's DHCP server into believing that you got a new router or a new computer so you get a new IP, but always in the same subnet. You can accomplish the same by turning off the router for a while and then turning it back on. New IP, but again nearby in the same subnet.
Loooong story as to why that is the way it is. Routers and routing tables and BGP....
Why are you doing this anyway? If you are worried about being tracked online.... that's mostly done with cookies. Clear your browser cookies regularly.
