getting an error where my xbox cannot resolve DNS - happens with wireless and wired...

Hello! Thanks for reaching out on the forums. Here are some steps that might help resolve your issue.

Like many other network devices, the Xbox 360 uses the domain name system (DNS) to translate Internet addresses into numerical Internet protocol (IP) addresses. If the console is unable to retrieve the values for the DNS, the Xbox 360 will not be able to
connect to the Xbox Live network properly. The following demonstrates how to resolve most issues surrounding DNS errors, which can be caused by faulty networking equipment or incorrectly set DNS values.

1. Turn off the Xbox 360 console by pressing the power button on the front of the console. If you have a wireless networking adapter installed, unplug it from the USB port. Turn off all wired or wireless hardware capable of supplying an Internet connection
   to the Xbox 360 console; this includes wired and wireless routers and modems.
   
2. Turn on the modem and allow it to fully restart. Then, turn on the wired or wireless router connected to the Xbox 360 console and allow it to fully restart. Repeat this process for every other piece of hardware connected to the console.
   
3. Turn on the Xbox 360 console and scroll to “My Xbox”. Select “System Settings” and then select “Network Settings”. Choose between “Wired Network” or “Wireless Network” and then select Test Xbox Live Connection. Allow the test to fully complete. If any DNS
   errors persist, move on to the next step.
   
4. Enter a manual DNS value for use with the Xbox 360 console. This value can be retrieved from your computer by checking its network settings, or by contacting your ISP. Make sure to copy the values down on a piece of paper. After acquiring the correct DNS
   values, select the wired or wireless network you’re using on your console and select “Configure Network." Choose “DNS Settings” on the “Basic Settings” tab and select Manual. Select “Primary DNS Server” and enter the first DNS value. Select “Secondary DNS
   Server” and enter the second DNS value. Afterwards, test the Xbox Live connection once more.
   
5. Use a direct connection to your modem if you still have DNS errors. Directly plug your Xbox 360’s Ethernet cable into the modem. If the DNS error is resolved, you may be having problems with your router. Consult the router’s instruction manual for how to
   resolve this problem.

Hi
forzainformer2,

Thank you for coming to the forums. We'd be happy to help but we are going to need some more information about the issue because that error code isn't going to bring up any results in the database and there a many factors as to why the console cannot connect
to the internet or Xbox Live.

What manual DNS settings did you input and what was the reasoning for that? Were you getting an error that the "DNS is not resolving"?

Do you connect wireless or hard-wired? Are you able to sign in to the profile?

Give us some more information on the error and what steps you took that lead you to manually inputting a different DNS settings.

DNS won't have a effect on your download speeds, but could speed up you web browsing speeds. DNS translates names into IP addresses, so when you type google.com into a web browser, that request goes to the DNS and it resolves google.com to 64.233.183.139(or
what IP your DNS may resolve to) and then your computer connects to that IP address.

but wired or wireless will not make a difference, assuming the wireless signal is good.
