Cannot conect to WiFi after changing a router

Hi

Have you tried the troubleshooting steps located here; Xbox 360: I get an error message when I test my Xbox Live connection , Help
with my Xbox 360 network connection

Yes. The guides lead to the same connection issue. So I've tried to restore factory defaults without any effect, and to define a network manually as well. And I'm sure I use the correct password.

Hi there Batman,

Thanks for reaching out here in Xbox Forums. I understand there is a problem with connecting to Xbox Live on the Xbox 360. I recommend to try the following article:

Restore Xbox 360 network settings to factory defaults

Try this:

Note Before you reset the Xbox 360 console's network settings, make sure that you write down the current settings in case you have to restore them later. If you are using a secured wireless network, you will also need your wireless network
password.

1. Press the Guide button on your controller, select Settings, and select
   System Settings.
2. Select Network Settings.
3. Select Wired Network or the name of your wireless network when the network list is displayed.
   

Select Configure Network.

1. On the Additional Settings tab, select Restore to Factory Defaults. When prompted, select
   Yes, Restore to Factory Defaults.
   

Note This resets the console's network settings only, and not other settings.

1. Turn off your console.
2. Turn on your console.
   
   Wireless only: You will receive a message to configure wireless settings. Follow the on-screen instructions to connect to your wireless network.

Now test your Xbox Live connection:

1. Press the Guide button on your controller, then select
   Settings, select System Settings, and select Network Settings.
2. Select the name of your Wireless Network, or select
   Wired Network for a wired connection.
3. Select Test Xbox Live Connection.

Give this a try and let us know the results.

Hi!

Probably the router's encryption mode (with tkip&aes) creates connection problems. Can you try setting AES only with WPA2? It would also be possible to set WPA+AES.

You may need to configure the settings manually, if you don't know the information you will need to contact your ISP.

Select Configure Network. Now you can manually configure your IP settings, your DNS settings, your PPPoE settings, or your
MAC address.

See the steps below for the settings you want to configure.

Manually configure your IP settings

1. On the Basic Settings tab, select IP Settings.
2. Under Edit IP Settings, select Manual.
   • To manually set your IP address, select IP Address, enter the IP address, select Done, and then select Done.
   • To manually set your subnet mask, select Subnet Mask, enter the subnet mask, select Done, and then select Done.
   • To manually set your gateway, select Gateway, enter the gateway address, select Done, and then select Done.

Manually configure your DNS settings

1. On the Basic Settings tab, select DNS Settings.
   
2. Under Edit DNS Settings, select Manual.
   
3. Select Primary DNS Server, enter the primary DNS server address, then select Done.
   
4. Select Secondary DNS Server, enter the secondary DNS server address, select Done, and then select Done.

Manually configure your PPPoE settings

1. Under Configure Network, select the Additional Settings tab.
   
2. Select PPPoE settings.
   
3. Select User Name, enter the PPPoE user name, then select Done.
   
4. Select Password, enter the PPPoE password, then select Done.
   
5. Select Service Name, enter the PPPoE service name, select Done, and then select Done.

Manually configure your MAC address

1. Under Configure Network, select the Additional Settings tab.
   
2. Select Advanced settings.
   
3. Select Alternate Mac Address, enter the MAC address, select Done, and then select Done.

Manually configure your host name

1. Under Configure Network, select the Additional Settings tab.
   
2. Select Advanced settings.
   
3. Select Host Name, enter the host name, select Done, and then select Done.

I'm not able to connect to the network. So all I have is a failed test status on network.

I've tried to switch from 802.11b/g/n to 802.11g (which is exatcly the 2.4 GHz mode) restarting the router, but there is still no effect.

Is there anything i could try? In the worst case I have to use the ethernet cable which is not too convenient. Anyway, thank you for all of the pieces of advice.
