Xbox 360 cant find any network connections

The Xbox 360 Slim works with wireless. It has for me in the past even on this specific xbox

Xbox 360 is not designed for wireless so use Ethernet which the console is designed for.

Start with running the Xbox network connection test. Ensure that Wireless is selected under Configure Network, Basic Settings. Then, using a computer, log into your router and check the device list to see if there is an IP conflict or if your Xbox shows at all.

If it wasn't resolved, shut down the Xbox 360 and unplug it for 1 minute. Unplug the wireless network adapter from the USB port. Start the Xbox. Press the Guide button on your controller, go to Settings, and then select System Settings. Select Network Settings. Select your wireless network name if it shows. Select Configure Network. On the Additional Settings tab, select Restore to Factory Defaults*. When you are prompted, select Yes, restore factory defaults. *This does not affect ANY other settings on your Xbox, it only resets the wireless data. Try to reconnect to your network.

I assume your WiFi adapter is a USB type. It could be the adaper is done. In the past, I had a computer motherboard style wifi card *and* a wireless usb adapter die. I've also has a router dropping signal, and it turned out that model was known to go that way at it's age.

In the meanwhile, you can use a LAN cable. Almost guarantee you'll have a faster connection by cable.
