This article understands how to setup a home network without internet. Assuming that there is a combination of wired and wireless users, a wireless router can be used. Troubleshooting tips are also provided at the end of the section.
Step 1
Purchase a wireless router in case you do not have one.

Step 2
Wireless routers comes typically with 4 port inbuilt switch. Connect the wired users to the inbuilt ports on the switches.
Manually configure the DHCP server on the router. The screenshot is shown below.
The LAN IP address of the router is 192.168.0.1. Configure the IP address range of the DHCP server (IP Pool range) as shown above. This is required for providing IP address to users on the network for internal communication. Since there is no internet, DNS configuration is not required, although it can be set as 192.168.0.1.

Step 4
Check if the wired user / computer has received an IP address belonging to the above pool. This can be verified using ipconfig command on the command prompt of the system.
Step 5
Configure a SSID name for wireless access , along with associated security protocols like WEP or WPA. Connect the wireless device (Laptop / Smartphone) to the SSID by configuring appropriate security parameters for WEP / WPA. Check if the laptop has received an IP address belonging to the above pool. This can be verified using ipconfig command on the command prompt of the system.

Step 6
Ping the systems to check if basic connectivity is working between them. For example if the IP address of the wired system is 192.168.0.2 , type the command ping 192.168.0.2 from the command prompt on the wireless device to test basic connectivity.
Troubleshooting Tips
1. Unable to receive IP address.
If any system on the network is unable to receive an IP address, check if the system is configured as a DHCP client. Also check if the DHCP server on the router is configured appropriately.
2. Unable to ping devices on the network
Check if both systems have received an IP address from the DHCP server. Check if a desktop firewall on any of the systems are not blocking any ping packets. Ensure that the systems have not been configured accidentally with a static IP address in a different range.
