Re: Can i get a New IP?
Ip addresses are based on the mac address of the NIC card in your computer or WAN mac of your router. Lease times on these are supposed to be 4 days. If you disconnect the device from the modem for 4 days, your lease will not be able to renew itself and essentially, it could be taken by someone else.
Unplugging the modem will not change your IP address.\
If you leave the modem unplugged over 7 days, then the modem's IP lease may be lost, and new modem ip will be given, but because the mac address of your network card is the same, it will still pull up the same IP address. |

| I assume that once the IP goes back into the IP pool, it could be assigned to anybody. By default, being placed back in the pool means that the ARP table no longer is matching your MAC address to that IP so you wont get it again unless by chance.
Changing your MAC or NIC, which is easy to do with a Linksys, will get you a new IP maybe. HOwever, they'll then begin to charge you for 2 IP addresses based on you using two computers(MAC addresses) on their service.
Check the lease time and leave the device that's reflecting its MAC address to ATTBI off for just over that period of time, and see if that works. |

Wouldn't releasing the IP via winipcfg (Win9x) or a ipconfig /release (NT), before switching off the modem make it possible to pull a new IP in less than 4 days; Or is it the WAN side IP address that causes the problem

I have changed my IP the way I describe pretty often for various reasons... worked within an hour every time just about. A couple times I've had to let it go overnight befor eit would grab a new IP. I have had other members here do it this way, and it worked just fine for them. Don't know what else to say except works for me!
