+# Wiznet W5100S-EVB-Pico
+
+## Network Example
+
+To use network / socket based code, connect ethernet port to network with DHCP running:
+
+```
+>>> import network
+>>> nic = network.WIZNET5K()
+>>> nic.ifconfig()
+('192.168.0.18', '255.255.255.0', '192.168.0.1', '8.8.8.8')
+>>> nic.dhcp(True)
+('192.168.0.10', '255.255.255.0', '192.168.0.1', '192.168.0.1')
+```
+At this point standard network communications libraries should work.
