Take speed before you posted? What's with all the agitation?

Why do you need to change the IP Address?

Also much more importantly here the Modem should not take 10 minutes to reboot so what is it and have you tried rebooting it without the computer connected if the computer is the only thing directly connected tot he modem?

What's wrong with using a Static IP Address anyway? The IP Address that the Modem gets is distributed by the ISP and that is what gives you a connection to the ISP then the Modem is issuing a Internal IP Address to any connected computers or it may issue a DHCP Address again to the Internal LAN. Have you tried turning off the DHCP Addressing int he Modem and you should enable the Firewall in it which will be a Nix Firewall.

Also the Windows Firewall is next to useless so while it doesn't hurt to be on it's not all that useful either.

Here if this is a one computer modem combination I would reset the Modem to it's defaults and start again. They are not that complicated to set up and it really sounds as if you have messed something up when you configured it so that is causing your problem whatever that happens to be.

You cannot use ipconfig/renew on your public IP when it is a) on the WAN side of the router/modem, and b) controlled by your ISP!.

But yeah, depending on your router, you may actually be able to assign the public IP to a device on the LAN side of the router. But you still can't use ipconfig on it.

Why do you require changing your public IP so frequently?

Sounds liek a configuration issue with your adapater or in router config.

What i would first do is uninstall your network apater and reinstall.
right clien my computer, prop[erties, hardware tab and clicm device manager, drop down network adpaters and uninstall, from there click on scan for hardware changes at tope of device manager screen (computer with magnifying glass icon).
