Xbox 360 elite

Check out this link and look at the part about setting up a dedicated i.p. address on your router: http://routerdisconnects.blogspot.com/

This is just one of MANY solutions to your problem. It could be also that your router is AutoRenewing which is not easily identified as an issue on your computer but can be a big issue on your Xbox Live as it will disconnect you every time it attempts to AutoRenew.

Also ready this link on how to setup a router for Xbox Live. It is Linksys Wireless-G but has the basic principles down for your setup of most any router.

And lastily here is the always helpful Xbox Support link that can guide you through some issues with your connection: http://support.xbox.com/en-us/pages/xbox-live/troubleshoot/connection-issues/default.aspx

Maximum transmission unit is 1500, but for the Xbox 360 it "must" be set within the range 1364 - 1492
Since there's no MTU settings for the TG782T. your only choice is to replace it with routers like Linksys, Belkin, Netgear.

To connect your Xbox 360 gaming console to a NETGEAR router's wireless network:

1. Turn off your Xbox 360 and disconnect anything from the I/O port on the back of the console.
2. Insert your Xbox 360 wireless adapter to the I/O port as instructed by the wireless adapter manual.
3. Connect the wireless adapter cable to your Xbox 360 I/O port.
4. Flip up the network adapter's antenna.
5. Turn on your Xbox 360.
6. • If you are using an unencrypted wireless network, your Xbox should connect to it automatically and you do not need to proceed to Step 6.
   • If you are using an encrypted wireless network click the System tab, and then click Network Settings and continue with Step 6.
7. On the Network Settings page, select Edit Settings.
8. On the Edit Settings page, select your wireless settings on the Basic Settings tab.
9. On the Select Wireless Network page, select your wireless network.
10. On the WEP Network page, type your wireless network key, and then click Done.
11. • The wireless network key is simply the password for your wireless network. If you do not remember your wireless network password, please see the following article:
      Forgotten or Lost Password for Wireless Networks and Devices
12. On the Apply Settings page, click Test Xbox Live.
13. If this is the first time you have connected your Xbox 360 to Xbox Live, you will probably be prompted to apply an update. If there are no updates, the Xbox Live Connection page shows that you're connected to Xbox Live. Press the Y button on your controller to continue.

If testing the Xbox it says DNS failed, then update your NETGEAR router firmware:

1. From your computer, open an Internet Browser and navigate to http://kb.netgear.com to download the firmware for your router.
2. Log in to your NETGEAR router by browsing to http://www.routerlogin.net or http://www.routerlogin.com. Enter the username (admin) and password. By default, the password is password or 1234 unless it has already been changed.
3. Click Router Upgrade on the top left pane under Maintenance, browse for the firmware downloaded and click Upload.
4. Wait for the router to reboot.

let me know if further help needed

use this method instead...

that happens alot when one or more device (for instance, the xbox 360 and a cpu) are trying to use the same ip address make sure you have the xbox 360 and all other devices (cpu's/printers) that are connected to the router set to aquire ip address automatically

Hi,

problems usually happen, when the signal strength drops.
I,d suggest hard-wiring the 360 to the PC or router, for optimal performance.

Thankyou for using fixya.

You need to enter the router configuration. How you do this varies by model, but usually involves typing your gateway address into a web browser. Then, you need to assign your xbox an internal IP address and activate port triggering or forwarding (depending on the sophistication of your device) to send information on the designated ports to the Xbox.Was this solution helpful?
