I just changed internet service and now I can't obtain an IP address for my X-BOX 360 online service

Changing TCP/IP settings Win 7 TCP/IP defines how your computer communicates with other computers.
To make it easier to manage TCP/IP settings, we recommend using automated Dynamic Host Configuration Protocol (DHCP). DHCP automatically assigns Internet Protocol (IP) addresses to the computers on your network, if your network supports it. If you use DHCP, then you don't have to change your TCP/IP settings if you move your computer to another location, and DHCP doesn't require you to manually configure TCP/IP settings, such as Domain Name System (DNS) and Windows Internet Name Service (WINS). To enable DHCP or change other TCP/IP settings, follow these steps:

1. Open Network Connections by clicking the Start button , and then clicking Control Panel. In the search box, typeadapter, and then, under Network and Sharing Center, click View network connections.
2. Right-click the connection that you want to change, and then click Properties. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
3. Click the Networking tab. Under This connection uses the following items, click either Internet Protocol Version 4 (TCP/IPv4) or Internet Protocol Version 6 (TCP/IPv6), and then click Properties. The Network Connection Properties dialog box
4. To specify IPv4 IP address settings, do one of the following:
   • To get IP settings automatically using DHCP, click Obtain an IP address automatically, and then click OK.
   • To specify an IP address, click Use the following IP address, and then, in the IP address, Subnet mask, and Default gateway boxes, type the IP address settings.
5. To specify IPv6 IP address settings, do one of the following:
   • To get IP settings automatically using DHCP, click Obtain an IPv6 address automatically, and then click OK.
   • To specify an IP address, click Use the following IPv6 address, and then, in the IPv6 address, Subnet prefix length, and Default gateway boxes, type the IP address settings.
6. To specify DNS server address settings, do one of the following:
   • To get a DNS server address automatically using DHCP, click Obtain DNS server address automatically, and then click OK.
   • To specify a DNS server address, click Use the following DNS server addresses, and then, in the Preferred DNS server and Alternate DNS server boxes, type the addresses of the primary and secondary DNS servers.
   The Internet Protocol Version 4 (TCP/IPv4)Properties dialog box
7. To change advanced DNS, WINS, and IP settings, click Advanced.

Using a router is a great way to create a home or office network without having to spend a lot of money.
As long as you have a broadband Internet connection through an Internet service provider, you can use a router to get all of the computers in your home or office connected.
If you have chosen Netopia as your router brand of choice, you will have to configure it to make your network operable.

Power on your Netopia router, broadband modem and computer.
Open your Internet browser.
Type the router IP address, 192.168.1.254, into the address bar. Hit "Enter" on your keyboard. Log into your Netopia router with the username and password assigned to you by your Internet service provider.
Select "Expert Mode."
After entering expert mode, you will see a menu bar at the top of the configuration window.
Click on the "Home" tab. Many Internet service providers will ship your Netopia router to you preconfigured.
If it is preconfigured all of the fields, such as IP address, subnet mask and default gateway will already be populated. If the fields are not populated, proceed to the next step.


Click on the "Configure" tab. Select "WAN." Select "ATM." Enter the "VPI" and "VCI" numbers provided by your Internet service provider.
Choose your encapsulation option.
For example, "Routed IP," "PPPOE," etc... Click "Submit."

Select "WAN" on the left side of your configuration window.
Choose the "VCC1" option. Select the option to "Enable Interface."
If you do not have your own IP address, choose the option to "Obtain an IP Address Automatically."
If you do have your own IP address, uncheck the automatic IP address box.

Type in your IP address if you have your own.
Enter your subnet mask.
This information can be obtained from your Internet service provider.
Select the "NAT" option if you are using your own private IP address for your network connection. Click on "Submit."

Select "WAN" on the left side of your configuration window.
Ensure that there is a check in the "Gateway Option" box and "IP Address" is selected as the "Interface Type."
Type in your "Default Gateway" address.
This can be obtained from your Internet service provider.
Click "Submit."

Select the "Configure" tab at the top of your window. Select "LAN."
Select "Enable Interface."
Type in the IP address for your router and subnet mask. Click "Submit."

Click on the yellow caution symbol on the top right hand side of your window to save all configuration changes.
Click on "Save."
Restart your computer for the changes to become effective.

There are two kinds of IP addresses. Internal and External.

Every system has its unique IP address. That is internal ip address. It can be obtained by the following steps:

1.Go to start menu
2. choose run
3.Just type cmd into the search box
4.Command prompt will appear
5.type ipconfig

Then it will show your IP address of your system.

And every website has its own IP address that is External IP address. It can be obtained from Ip-details.com .I use this site to get my IP address. This site can provides Internet service provider, location of an IP address,latitude,longitude etc

every user created on the OS will have to have different settings.....

before making changes...get the foll info from your internet service provider
IP Address, Subnet mask, Default Gateway, DNS server address both primary and secondary

once that's available.....

you can use different settings in in WinXP as below....

Control panel / Network Connection /Local Area Conn /Right click / properties/ Internet Protocol TCP IP / Check Box / Propertis / in IP address use the IP address that's been assigned by your internet service provider

log in to first user accunt and make the settings....for....
IP Address, Subnet mask, Default Gateway, DNS server address both primary and secondary
use the info obtained from the service provider.....
....then
in the IP address filed use some thing similar like this..(check your internet service provider for that info).....the foll is only an example from my PC
say....192.168.1.2 for user ONE

log out....
shut down and restart PC
log in to second user accunt and make the settings....for all the above fileds....then
in the IP address filed use 192.168.1.4 for user TWO....(note the difference of the last filed of the IP address....2 vs 4)...every new user a/c the last field of IP address keeps changing

1st user ....say 192.168.1.2
2nd user .........192.168.1.4
3rd user ..........192.168.1.6
etc...

Set your netgear router to DHCP or obtain an IP address automatically on the WAN, or public (internet) side

Are you trying to get an IP for your computer, or for your modem? Assuming your using a high-speed connection, possibly a router?

You can't get an IP address on the Xbox that way. You need to get an IP address from a device that works as a DHCP server such as a residential router. Connecting the Xbox to the PC will do nothing for you.
