Wireless Access Points

Correct Answer: Upgrade to a dual-band WAP supporting 5 GHz

Upgrading to a dual-band Wireless Access Point (WAP) supporting 5 GHz is the best solution, as the 2.4 GHz band is limited in bandwidth and prone to interference from other devices. This is likely causing the slow Wi-Fi connections. The 5GHz band provides faster speeds and is less susceptible to interference. Decreasing the MTU (Maximum Transmission Unit) size won't necessarily solve speed issues and it could create more network overhead, this is because smaller packets means more packets in total to transmit the same amount of data, thus not an efficient method in this case. Disabling SSID broadcasting would not improve speed, but rather make the network invisible to users which is more of a security measure than a speed improving tactic. Increasing the DHCP lease time would only increase the duration for which a device is assigned an IP address, but does not have a direct impact on the speed of the Wi-Fi connection.

Correct Answer: Set up a separate guest network with password protection

The best way to secure a Wireless Access Point (WAP) for guest users is to set up a separate guest network with password protection. This allows guest users to access the internet without gaining access to sensitive company resources. It also prevents unauthorized users from accessing the network as they would need the password. The other options are not recommended. Disabling wireless encryption for guest users would make the network vulnerable to unauthorized access and potential attacks. Allowing guest users access to the company file servers pose a security risk as they could potentially access and manipulate sensitive data. Turning off SSID broadcasting would not necessarily secure the network for guest users as it only hides the network name from being publicly displayed but does not prevent unauthorized access.

Correct Answer: Relocate the WAP to a central location.

The best solution to improve a user's weak signal and connection drops in their office is to 'Relocate the WAP to a central location'. The brick wall between the user's office and the WAP is likely causing the signal to degrade, lowering the quality of the connection. By moving the WAP to a more centralized location, the signal can be distributed more evenly across the environment, potentially diminishing the impact of physical barriers like walls. This solution will likely give the most significant improvementThe other answers are not as effective in this scenario. 'Increasing the WAP's transmit power' may only marginally improve the signal strength if the issue is physical barriers blocking signal propagation. 'Changing the channel on the WAP' will only be helpful if the issue is signal interference from nearby devices operating on the same channel, which isn't the issue stated in the question. Similarly, 'Decreasing the WAP's transmit power' would reduce the signal strength, further exacerbating the problem rather than solving it.
