My xbox 360 isn't finding my wifi

I'be got all the settings correct and my problem is my pc isn't finding my xboxs ip address, my thought is it isn't finding it because one is on ethernet (wired) and the other is on wifi, therefore it thinks they are on seperate networks and can't find
the ip address

Flashing green usually means that it's attempting to find a WiFi signal. Are you sure this isn't an issue with the wireless adapter if the Xbox 360 doesn't even give you an option to select WiFi in the selection?

Do I need to be able to connect to Xboxlive from my 360 to play them? ..Cause I have an Xbox Live account but I don't have a network adapter for my 360 to connect to my wifi so my 360 isn't connected to the internet yet.

I usually connect my PC and my XBOX with the companion app while my PC is on ethernet and the XBOX is on wifi, the opposite of your setup, but that should not be any problem as long as both are connected to the same net. When the setup is correct the PC
finds automatically the XBOX without any imput.

I would check also your router settings just in case and if possible try a wired-wired connection.

I don't know why it got not find you WiFi network but even when your Wifi is hidden you got find it normaly. But you need to do it manually like DrBogBrush said. I have a problem for myself at the moment that my Xbox 360 Slim will not connect with my WiFi
if my MAC address is enabled on the router. If i put this off the Xbox will connect right away. Maybe this helps you a bit.
