As long as your network adapter is for the Xbox 360, It will work fine.
It just won't be the same colour.

Xbox Wireless Network Adapter MN740
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.
Yes
Of course, yes you only need to order the Network Adapter for the XBOX 360.
The adapter connects you to Xbox Live but only if you have a wireless network and if you have a Xbox Live subscription.
It will if you buy the 100 dollar wireless adapter.
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
Google the Xbox 360 Wireless Network Adapter.
