Reduce the radio frequency interference around the wap.-802.11g uses the 2.4 ghz range which is also used by appliances such as microwaves. the connectivity problem occurs at around lunch time, which seems to indicate that the increased use of microwaves at around this time is causing rfi (radio frequency interference). we should thus attempt to eliminate this rfi. incorrect answers:a: 802.11a uses the 5.0 ghz range and will not be affected by other devices that use the 2.4 mhz range. however, we would need to change the wireless adapters on the workstations to 802.11a as well.c: in ad-hoc mode, two wireless devices can communicate directly, without the need for a wap. however, these devices would not have access to the wired network.d: by design, the wap is directly connected to the network but this will not overcome the rfi (radio frequency interference) that is affecting the wireless signal.references:david groth and toby skandier, network+ study guide (4th edition), sybex, alameda ca, 2005, pp. 251, 252, 255.
