Using the hub I can connect to the internet from my computer but my 360 is telling me it can not obtain an IP adress

Change the fixed IP address of your machine to DHCP.

If you are running Windows then

- Click Start, Control Panels
- Depending on which version of Windows you are using, look for Network and Internet
- Right click the connection you wat to change (in your case, choose the ethernet)
- Click the Networking tab. Under This connection uses the following items, click either Internet Protocol Version 4 (TCP/IPv4)
- To obtain IP settings automatically, click Obtain an IP address automatically, and then click OK.

That should resolve your problem

A "hub" just "splits" the Internet connection.
Each computer connected to the hub gets an IP-address from your ISP (Internet Service Provider).
However, some ISPs only allow each customer to use _one_ IP-address.
Ask your ISP for the capability to obtain a second IP-address.

Every device connected to the public internet is assigned a unique number known as an internet protocol (IP) address. IP addresses consist of four numbers separated by periods(also called a 'dotted-quad') and look something like 127.0.0.1 

since these numbers are usually assigned to internet service providers with region based blocks, an IP address can often be used to identify the region or country from which a computer is connecting to the internet. an IP adress can sometimes be used to show the users general location because the numbers may be tedious to deal with, an IP adress may also be assigned to a host name, which is sometimes easier to remember hostnames may be looked up to find IP adresses,and vice-versa. at one time ISPs issued one IP adress to each user. These are called static IP addresses. beacuse there is a limited number of IP adresses and with increased usage of the internet ISPs now issue IP adresses in a dynamic fashion out of a pool of IP addresses (using DHCP). these are referred to as dynamic IP addresses. This also limits the ability of the user to host websites mail servers, ftp servers, etc. in addition to users connecting to the internet with virtual hosting,a single machine can act like multiple machines (with multiple domain names and IP addresses).

Here is a link to their Support site: http://support.xbox.com/support/en/us/nxe/default.aspx Select "Troubleshooting/Connection" errors page. On the LEFT, select "Network Help". That should put you in the area you need.

every computer has an ip adress you might have to go to your internet setting and find some thing that says some thing like... internet adress hook up hopefully you keep files on your computer becuase with out your ip adress you might not be able to hook up its sorta like a combination hope it helpes:)

I would suggest that first you stop using the first modem. Then plug your computer into the modem and install using the comcast cd that came with your welcome package. If that doesn't work please tell me.

sounds to me like you have the security turned on . Just type in your security key on PS3 and it should connect. Best of luck!

Most of DSL modems are connected to PC with USB cable...
n if ur server is connected with other pc on lan .. you can use internet sharing option available in winxp.

Following are the steps to enable Internetsharing for other pcs.


How to use Internet Connection Sharing loadTOCNode(2, 'summary'); To use Internet Connection Sharing to share your Internet connection, the host computer must have one network adapter that is configured to connect to the internal network, and one network adapter or modem that is configured to connect to the Internet.

On the host computer loadTOCNode(3, 'summary'); On the host computer, follow these steps to share the Internet connection:

1. Log on to the host computer as Administrator or as Owner.
2. Click Start, and then click Control Panel.
3. Click Network and Internet Connections.
4. Click Network Connections.
5. Right-click the connection that you use to connect to the Internet. For example, if you connect to the Internet by using a modem, right-click the connection that you want under Dial-up.
6. Click Properties.
7. Click the Advanced tab.
8. Under Internet Connection Sharing, select the Allow other network users to connect through this computer's Internet connection check box.
9. If you are sharing a dial-up Internet connection, select the Establish a dial-up connection whenever a computer on my network attempts to access the Internet check box if you want to permit your computer to automatically connect to the Internet.
10. Click OK. You receive the following message: When Internet Connection Sharing is enabled, your LAN adapter will be set to use IP
    address 192.168.0.1. Your computer may lose connectivity with other computers on
    your network. If these other computers have static IP addresses, it is a good idea to set them
    to obtain their IP addresses automatically. Are you sure you want to enable Internet
    Connection Sharing?
11. Click Yes.

The connection to the Internet is shared to other computers on the local area network (LAN). The network adapter that is connected to the LAN is configured with a static IP address of 192.168.0.1 and a subnet mask of 255.255.255.0

let me know if it helps.

best regards,

wired conection , connection test fails obtain ip adress connect but connection internet failed.

Connect it to your router with an ethernet cable.
Make sure the router is setup correctly to your modem, if you can connect all your devices by ethernet cable to the internet then it's set.
If you are using a wireless connection and if it asks for the WEP or WPA key, make sure that you are entering the correct encryption key. You may want to call your router manufacturer to know the correct key for the wireless connection. FYI, it will say that the wireless network is connected but it will still fail the IP Address.

If you have a wired connection and the IP Address or DNS failed, I suggest you to call your Internet Service Provider to check for the Internet connection and obtain these (static IP address, subnet mask, default gateway, primary DNS server and secondary DNS server). If your Internet is okay, enter the IP settings manually on the console (System > Network Settings > Edit Settings > IP settings).

That should work.
