I don't know what kind network you have currently.
1. If you use DSL or Cable modem, buy the Access Point with Cable/DSL Router($~200) and one 802.11b PC card($50 from justdeals.com).
2. If you already have the router or switch for the network, buy one access point($180~$160) and one 802.11b PC card.
3. If you plan only to conncent desktop and CF-01, buy Wireless USB Network Adapter(~$99) and one 802.11b PC card
4. Or buy one Instant Wireless PCI Adapter(~$40) and two 802.11b PC cards.
Previously I have Acer Warplink(paid $28) which doesn't have W2k driver. I have to use my old PPro and Win98 to make it work. Last week I bought 2 802.11b PC cards from uBid for $35 each(they were dumping them last week) and SMC access point from buy.com for $190 - $20 rebate - $20 coupon. The access point will plug in to my cable modem router, so my CF-01 can surf on the net without turn on other computer.
