Which of the following should a wireless technician do NEXT to troubleshoot this issue?

Several WIFI users are reporting the inability to connect to the network. WLAN users on the guest network are able to access all network resources without any performance issues.

The following table summarizes the findings after a site survey of the area in question:

Which of the following should a wireless technician do NEXT to troubleshoot this issue?

Answer: A

Explanation:

The issue of WIFI users being unable to connect while WLAN users on the guest network can access all resources indicates a problem with channel overlap or interference. By reconfiguring the channels, interference can be minimized, improving connectivity for WIFI users. According to 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 RSSI values (-44dBm and -41dBm), which can also cause interference. A possible solution is to use only non-overlapping channels (such as 1, 6, and 11) and adjust the power levels to avoid excessive signal strength.
