1. What are the factory default username and password of a TP-Link router? Why is it important to change the
default username and password of a SOHO router?
Answer: admin & admin. It’s important to change these because it’s extremely easy for a bad actor to
simply guess this and gain admin level access to the router and thus the network.
2. To protect a SOHO wireless network with a small number of devices, which address management method
provides more control, configuring the device IP addresses manually (static IP) or using a DHCP server (dynamic
IP)? Why?
Answer: For protecting a network and its devices, DHCP will always be the answer regardless of the size.
This is because with DHCP the devices are automatically configured with fresh IP address as needed, and
as these IPs are updated even if a bad actor was able to get the IP of one device, that IP won’t always be
accurate. If the device has a static IP, then once it’s compromised it’s compromised until someone
manually changes it.
3. What does MAC filtering do? If needed, when would you use deny filtering rules and when would you use
allow filtering rules? What happens to devices that want to connect, if the “Allow the stations specified by any
enabled entries in the list to access” function is enabled but there are no entries in the list?
Answer: MAC filtering allows you to control the wireless stations that can access the AP based on their
MACs. If an unknown and potentially malicious device was discovered on the network, and it’s MAC is
visible, then you can use MAC filtering to deny that device access to the network’s AP. If no entries are on
the list, then no wireless stations can access the AP.
