XBOX 360 Not connecting to wifi

What specifically would allow the Xbox 360 Wireless Networking Adapter to connect while the built-in wifi would not?

My Xbox 360 S detects a wireless signal with 4 bars, and I am testing it while sitting it right next to the modem, so there is no issue with signal strength.

My Xbox 360 S's built-in wifi is able to connect to a hotspot, and it is even able to connect to my neighbor's wifi from my house.

I have the same problem and i resolve using wifi connection and no Ethernet cable.

I think that all of you have a cable connection.

With wifi connection Xbox download 360 information, then you are able to download your 360 profile. Try more time if don't start immediatly.

But if you return to use Ethernet cable the problem come back and is not possible connect your profile to internet.

This have no sense, the Xbox one is connect, my Xbox 360 use an Ethernet connection and go online with no problem.

But my 360 profile on Xbox one need only a wifi connection??

I already explane this thing in this forum, but no one of ms support give me a response.

I still have my white original 360 and I use wifi so if you're using wifi too, then try disconnecting from your modem from your xbox 360 wifi and re-connect both of them.

I'm having the same problem. It works fine on my Xbox one but not my 360. Can't log in, can't connect to wifi, and it keeps saying it's my wifi, but it's connected and fine. They need to fix this

Same problem here. My new xbox 360s connects to my network via internal wifi but it will not connect to xbox live. Everything else in the house connects fine. My xbox even connects when I plug in the old Adapter( from my last xbox) meaning the issue is with
the internal wifi. This is one reason I bought a new xbox slim(internal wifi) this is BS!
