Different operating systems will have different ways to set the different SOHO network settings. But the names of settings should be similar across operating systems. For example, all operating systems should have an option for automatic configuration for speed and duplex as well as DHCP addressing.
The end user device configures based on your SOHO router. By default the device will automatically configure the IP information. The IP address, subnet mask, default gateway, and DNS servers pull from the SOHO router information. But you can also configure the end device to have a static IP Address. For example on a Windows machine, this would be set via: Congtrol Panel > Network and Internet > Network Connections > Right click on a network card and select Properties > Internet Protocol Version 4 (TCP/IPv4) Properties. It’s best to assign a static IP that is outside the DHCP range so that you don’t end up with conflicts if the DHCP also assigns that same address.
Connect your end device to the wireless SSID that you set up and enter in the SSID password if set.
For wired devices, you should be able to simply plug into the router or switch and be connected to the network.
