Decrease power in AP 3 and AP 4
Answers
D.
Decrease power in AP 3 and AP 4
Suggested answer: A

Explanation:

The issue of WIFI users being unable to connect while WLAN users on the guest network canaccess all resources indicates a problem with channel overlap or interference. By reconfiguringthe channels, interference can be minimized, improving connectivity for WIFI users. Accordingto the table, AP 1 and AP 2 are using adjacent channels (2 and 1), which can cause interference.AP 3 and AP 4 are using non-overlapping channels (5 and 11), but they have very high RSSIvalues (-44dBm and -41dBm), which can also cause interference. A possible solution is to useonly non-overlapping channels (such as 1, 6, and 11) and adjust the power levels to avoidexcessive signal strength.Reference:Wireless Troubleshooting -- N10-008 CompTIA Network+ :5.4,Network Troubleshooting Methodology - N10-008 CompTIA Network+ : 5.1
