A network administrator is troubleshooting an industrial sensor deployment on the 2.4 GHz spectrum experiencing heavy packet loss and poor signal quality. An RF audit reveals that surrounding access points are configured on channels 2, 4, and 9 using 40 MHz channel widths. Which of the following actions should the administrator take to resolve the wireless interference issues? (Select TWO.)
- Reassign access point radio frequencies to non-overlapping channels 1, 6, and 11Answer
- Reduce the channel width configuration on the 2.4 GHz radios from 40 MHz to 20 MHzAnswer
- CIncrease radio transmit power to maximum levels on all access points
- DMigrate authentication from pre-shared key (PSK) to 802.1X enterprise authentication
Answer
The administrator should reassign access point radio frequencies to non-overlapping channels 1, 6, and 11, and reduce the 2.4 GHz channel width configuration from 40 MHz to 20 MHz.
Reassigning 2.4 GHz radios to channels 1, 6, and 11 removes adjacent channel overlap, while lowering the channel width from 40 MHz to 20 MHz limits spectral footprint so channels do not bleed into neighboring frequencies.
