Project Scope:

A wireless network with remote access from the office needs to be built at home. A desktop is available for 3 users at home and the third user has a laptop. At home, a high-speed Internet cable connection is available. For printing, there is a serial port printer available.

Network Requirement:

1. All the users should share the internet connection.
2. The laptop should have secure wireless access to the internet.
3. The desktop users should be able to access internet through the LAN.
4. The users should be transparent to the IP addressing system and should not be required to configure the same manually.
5. One of the desktop at home needs to be accessed from office.
6. All the users should be able to use the printer.

Here, I need a circuit diagram with explanation of every single network requirement

Thank you
