Xbox 360 Internet Issues

[Falgorn]

I have a slight problem with the internet at my house. All three of the computers (including a laptop) can connect to the internet. My Xbox, however, cannot.
I'm using the wireless adapter and trying to connect to a Linksys router, for general information.
Any ideas?

Have you tried hooking it up using an ethernet cable?
Could be that it just needs to update drivers and/or firmware...

1. Are you sure you entered the WiFi password correctly?

2. If the answer to 1 was "I don't have a password" go set one up. I probably won't fix your issue, but it's just good practice. I know whenever I have a neighbor w/ unencrypted wireless I do nefarious things whenever possible.
