Wireless networking is not an option for the Amiga as the network PCI cards i have been looking at don't have a supported controller card.
For an Amiga with an Ethernet card I think it should be possible to use one of the wireless Ethernet bridges that have come on to the market recently like
this one from DLink.
These allow any Ethernet device (such as a network printer) to be attached to a wireless network without any specific software so I can't see any reason why they wouldn't work on an Amiga.
