DI-624+ Wireless Networking.

[Seigal12]

I have a quick question with wireless networking, as this is my first one I have setup.

Basically, I have a DI-624+ router connected to a cable modem which currently connects via wires. I want to fit all the computers in the house with 802.11g cards.

My question is, do I have to connect one computer to the router with a cable OR will it be okay to have the cable modem connected to the router and then wirelessly to all the computers in the house? ...If you see what I mean.

I would prefer to connect all via wireless cards though, so will that still be possible, only connecting the modem to the router then everything else wireless?

The only reason I need to know is because I need to buy the cards and don't want to waste more money then I need to...
