Your wireless network consists of multiple $802\mathrm{.}11$n access points that are configured as follows:

SSID $($hidden$)$: CorpNet

Security: WPA$2-$PSK using AES

Frequency: $5\mathrm{.}75$ GHz

Bandwidth per channel: $40$ MHz

Because of the unique construction of your organization's facility, there are many locations that do not have a clear line of sight between network clients and access points. As a result, radio signals are reflected along multiple paths before finally being received. The result is distorted signals that interfere with each other.

What should you do$?$

answer

Switch to RADIUS authentication for wireless clients.

Implement antenna diversity.

Reduce the power of the access point radio signals.

Install directional access points.
