Wi-Fi Equipment Issues

This chapter describes limitations in the criteria set by 802.11b to establish
the reasonable use of low-level encryption to overcome present WEP
limitations; however, 802.11b equipment purchased before the improved
equipment is available will almost certainly have to be retired rather
than upgraded. It seems probable that the upper-layer solution will
require the services of a technician skilled in this area. Currently, the
physical-layer issues making 802.11b vulnerable to a variety of denial of
service attacks probably cannot be removed without substantial renovation
of the existing DS PHY portion of the standard.
