Microwave ovens and some cordless phones operate at the same radio frequency as the
Integrated 54g ™ enabled notebook. When the microwave oven or cordless phone is in use,
it interferes with the operation of the wireless network. Therefore, keep the Integrated 54g
enabled notebook at least 20 feet away from microwave ovens and any cordless telephone
that operates at a frequency of 2.4 GHz.
Some homes and most offices are steel-framed structures. The steel in such buildings may
interfere with the network's radio signals, thus causing a slowdown in the data transmission
rate. Try moving the Integrated 54g
to see if performance improves.
If the network has an access point (AP), check all of the cables and make sure the power
LED on the front of the AP is green. Verify that all of the wireless network properties values
are correct (see "Viewing or Modifying the Wireless Network Properties" on page
make sure the computer is receiving a good signal from the access point.
