I have gone through the troubleshooting assistant, for this issue, going through all the trouble even to check my router settings online, only to see that my DHCP (spelling?) was fine. I have recently gotten a new router, and all my other devices can connect without any trouble; My phone, my brothers phone, etc. My Xbox 360 on the other hand, could not connect to the network. I have tried everything, from resetting to default settings (in advanced settings under configurations I believe), to personally inputting the name and password, to the precise letter. Whilst in my router's settings, I noticed it was set to, WPA2 - Mixed, and so in turn set it to WPA2 - Personal/AES. Even after the change, my Xbox 360 could not connect to the network. This is strange, because I have never had such a problem before. I have gone through every suggestion in the Xbox website's network troubleshooting assistant, and still no change. My Xbox 360 is a slim, and when I would go in to configure the network on the Xbox, the DNS, and IP settings would not show up other than 0's. As I said previously, I checked my DHCP settings, and they were all on. I have no idea what could be wrong, if anyone could help me, and needs information about anything in specific, please ask, otherwise thank you ahead of time for any help :).
