If you use DHCP on your laptop, it gets the IP-address from the modem. You can't change the algorithm that the modem uses.
You can assign a fixed IP-address if you wish. But why should you?
Hi all,
We have 2 computers at home. The main laptop and printer is connected via DSL or wireless to our modem and has a static IP address from our ISP and can't be changed to a rotating IP.
My question is that my laptop connects wireless to the modem but can I can my IP address every so often with affecting the static IP??
