the device cool, sufficient space should
be left around the switch for heat dissi-

face or be close to the air outlet of other
devices.
ACCESS & CONFIGURE
Note: If no DHCP server is available, the GWN7831 default IP address is 192.168.0.254.
Method 1: Login using the Web UI
1. A PC uses a network cable to correctly connect any RJ45 port of the switch.
2. Set the Ethernet (or local connection) IP address of the PC to 192.168.0.x ("x" is any value between 1-253), and
the subnet mask to 255.255.255.0, so that it is in the same network segment with switch IP address. If DHCP is
used, this step could be skipped.
3. Type the switch's management IP address http://<GWN7831_IP> in the browser, and enter username and
password to login. (The default administrator username is "admin" and the default random password can be found
at the sticker on the GWN7831 switch).
