its actually pretty easy, tons of info on the forum for netfront connectivity via wifi through your desktop or laptop.
1. check your wireless router and check if WEP is on or off.
(if on, make sure you know the key)
2. under Preference>Network, select wireless.
(hit the SCAN button and scan to see if there are any wireless network available)
3. once you can access the wireless network you should be able to hop online.
