you need a memory stick or a hard drive for your gamer tag to sign up for xbox live.
Xbox Wireless Network Adapter MN740
OK, well you were half right in your question. In order to play on XBox live you will need either the wireless network adapter or run an Ethernet cable from your 360 to your home router. Simply having the hard drive will not allow you to play on XBox live.
The adapter connects you to Xbox Live but only if you have a wireless network and if you have a Xbox Live subscription.
The newer models (with the internal hard drive and whatnot) do, but for older ones you'll have to buy an adapter separately.
You can use the xbox 360 still but the adapter or an Ethernet cable enables you to get xbox live and play online
It allows you to connect to xbox live on a wireless network
At your local game store.
Google the Xbox 360 Wireless Network Adapter.
As long as your network adapter is for the Xbox 360, It will work fine.It just won't be the same colour.
I am not going to say it is impossible for a different adapter to work, just unlikely . The Xbox 360 Wireless Network Adapter was made specifically for that purpose, so it is unlikely that a normal adapter will work if attached to the Xbox as they most likely will not be compatible.
