Netbooting Wirelessly
Unless a user has a wireless card with a PXE-ROM chip built into it, it is not easy to directly netboot over a wireless connection. BIOS-based PXE algorithms usually only search for a wired NIC to be used in a PXE netboot.
It is possible to connect a "wireless bridge" (i.e. a wireless router or access point set to the "bridge" mode) to the wired NIC of a PC. The PC then netboots through the wired Ethernet NIC as usual, but the data is then transmitted from the NIC to the wireless AP/router connected to it and then wirelessly "across the bridge" to a central wireless access point/router.
This requires two wireless devices (one wireless access point and one client device), making it a more expensive solution. It is sometimes, however, easier or less expensive than running extra Ethernet cables between the two points.
