During lunch time in the break room of a company, Wi-Fi connectivity on the 2.4 GHz band is intermittent.
Every other time of the day, it works fine.
What's the likely cause of this issue?

Who should be in the final meeting from the customer-side after successfully implementing a WLAN infrastructure?

What is the best method of gathering attenuation measurements from any building materials or objects?

A signal passes through a 10-meter cable, an amplifier, and then a filter. The amplifier has an output that is eight times higher in power than its input. Each meter of cable reduces the signal level by a factor of 4. The filter has a loss of 5 dB.
What is the total loss/gain of the three elements in series?
Response:

You are tasked with designing the WLAN to accommodate certain high density areas on your university campus where users frequently come and go. With a limited DHCP pool size (subnet mask = 255.255.252.0) for this WLAN subnet, you want to ensure that your DHCP addresses are used efficiently and are not exhausted, which would prevent new client Layer 3 connections. The DHCP server is a Windows Server 2012 R2 machine.
Your design task is to determine the best configuration to allow as many users as possible while avoiding WLAN service interruptions and also to use the available addresses as efficiently as possible.
What setting would be most effective at achieving this design task?
