My Wii will connect to the internet, but my Xbox 360 won't. Help?

Try an new cable ?
Have you checked your routers setting/updated the firmaware….
A bit more tech info might be usefull also..

Is it a wired or wireless connection?
Do you have an Xbox Live subscription?
Is your network slow or does the internet work fine?
Can you browse the web and play games on the Wii?

Press wifi association on your modem/ router while you set up the internet connection on the Xbox , then tell it to connect and it should connect .

mybe your wireless adapter at the back of ur xbox isnt plugged in rite or not switched on.
mybe you have a really old router.
mybe your xbox is too far away from your router
Thats all i can think of soz

open the ports on your wireless router. also, you’re router or modem (whatever you use to get online for the wireless xbox) should be compatible with the adapter. i believe the frequency should be set to 802.11a.

your modem or router might not be compatible so check that first.

these are the ports they had me open recently (i’m still having issues with terrible lag, but that’s my providers problem.)

xbox1 tcp 80
xbox2 tcp 3074
xbox3 tcp 53
xbox4 udp 80
xbox5 udp 3074
xbox6 udp 53

not sure how you would enter them on yours. i’m assuming of course that you’ve got a dynamic ip (meaning your ip address isn’t fixed) ALSO call your router/modem people to help you open the ports if you don’t know how to do it yourself. AND make sure your modem/router is configured for wireless.

OOOH! make sure there’s nothing in the way that could interfere with the signal! it makes a big difference. other electronic devices (like your telephone) will interfere with the signal and cause you to disconnect or lag out.

good luck and i hope i was able to help a little.
