how can i connect to the wireless in my xbox 360 ? i tried everything and didnt work

Go to the settings of your Xbox 360. There under the network settings go to the additional network settings and reset it to factory defaults.

Then have the console search for WiFi networks in the area. Does the SSID of your new modem show up?

If so, then provide the correct Passkey for the WiFi and connect.

If the WiFi doesn't show up, check your WiFi router if you have 2.4GHz WiFi enabled. Also make sure that you don't use "exotic" characters in your SSID like Umlauts (ÄÖÜ) or accented characters (áèû) or stuff like that.

Also could you please describe in more detail at what stage your console fails to connect when you do a connection test to Xbox Live?

Does it see your WiFi SSID?

Does it connect to the WiFi but not the Internet?

Does it connect to the Internet but not Xbox Live?

HI,

Reset your old wifi connection on the Xbox 360.

Hey ArthurBastos2

Have you been able too connect too wireless before? Not all xbox 360 models have wireless the early models do not.

Are you getting any kind of error when you try too connect too your wifi or is it not picking up any hotspots at all.

This page also has a lot of infomation too help
