You can't. The MAC address is a permanant part of the device.
If you are connected via broadband, your provider would need to change the address. If you are connecting via modem, your IP address changes each time you sign on. So you can disconnect and reconnect and this will change it automatically.
The cable modem MAC address is a twelve-character alphanumeric identifier. It is usually found on the back of the modem.
If your talking about a dial-up modem, it uses a public IP just like a ethernet card. It depends on your ISP, what range of IP addresses you are assigned when you connect (DHCP: automatically assigned IP address; IP address can change) or you could also have a static address( IP address is always the same).
yes i need change my password modem cant you fint it
Mac address
Your computers I.P. address is assigned by your ISP (Comcast, Charter, Cox, etc.) and is bound by your MAC address and/or cable modem. There are tricks of resetting your I.P., but the best way to do it is either request it via your ISP or leave your cable modem unplugged for 24 hours. You get about a 75% chance of it resetting that method.
It is unlikely that you can, as there is no logical reason for an IP address to change every 24 hours, it isn't likely that any modem supports this feature. In addition, most DSL connections would not change the IP address simply because of a power cycle. Because DHCP assigns the IP address to a specific MAC address, you are likely to get the same IP address back after a short power outage.
What describes the external IP address that is obtained by a router through a cable or DSL modem?
If you have a modem, simply unplug and replug your modem. You should be given a new IP address. If not, I honestly don't know. Best of luck though
No, the Hardware address in your network card will with high probability never change, unless you manually change this yourself.. A IP address change will not affect your mac address, but if you change your MAC address it is likely you will get a new IP address
It all depends on your router/modem manufacturer. Usually, you type in your IP address (ex: 192.168.1.1) into your URL. From there you would goto your security and change it from there. Look under wireless security
A modem purchased from your Internet Service Provider is generally required for them to provide you service. The MAC address assigned to your modem is registered in their system.
