2   Safety Precautions 
Before operating the wireless router, read the following precaution information 
carefully: 
  Use the type of power that user manual marks. 
  Use the power adapter that is packed within the device package. 
  Pay attention to the power load of the outlet or the prolonged lines. An 
overburden power outlet or damaged lines and plugs may cause electric 
shock or fire accident. Check the power cords regularly. If you find any 
damage, replace it at once. 
  Proper space left for heat dissipation is necessary to avoid any damage 
caused by overheating to the device. 
  Do not put this device close to a place where a heat source exits or high 
temperature occurs. Avoid the device from direct sunshine. 
  Do not put this device close to a place where is over damp or watery. Do not 
spill any liquid on this device. 
  Do not connect this device to any PC or electronic product, unless our 
customer engineer or your broadband provider instructs you to do this, 
because any wrong connection may cause any power or fire risk. 
  Do not place this device on an unstable surface or support.

4.4   Hardware Installation 
4.4.1   System Requirements 
Before installing the device, please ensure that the following items are ready: 
  At least one Ethernet RJ45 cable (10/100/1000Base-T) 
 One wireless router 
  A PC is already installed with the TCP/IP protocol and the PC can access the 
Internet. 
              SMART/RG SR400ac 802.11ac Gigabit Router User Manual 
20
4.4.2   Before You Begin 
Before you install the device, please pay attention to the following items: 
  When the device is connected to a computer, hub, router or switch, the 
Ethernet cable should be less than 100 meters. 
  Do not place this device on an unstable surface or support. Do not put this 
device on the ground. 
  Keep the device clean. Avoid the device from direct sunshine. Avoid any 
metal in the device. 
  Place the device in the center of the area, and try to optimize the wireless 
coverage. 
4.4.3   Connecting the Device 
To connect the device, do as follows: 
Step 1  Connect one end of the RJ45 cable to the LAN interface of the wireless 
router. 
Step 2  Connect the other end of the RJ45 cable to your PC. 
Step 3  Connect the power adapter to the power socket of the wireless router. 
4.5   Operation Range 
The operation range of the wireless router depends on the actual environment. The 
path and effect of signal transmission vary according to the deployment in a house 
or an office. 
4.6   Roaming 
Suppose that several wireless routers run in the same network. Each wireless 
router serves as a BSS that has its coverage range. One wireless client (for 
example, a notebook PC or PDA) can realize roaming from one AP to another AP 
accurately. In that case, the wireless client can communicate with the other devices 
within the coverage range of the wireless router. 
We suggest indoor use.
              SMART/RG SR400ac 802.11ac Gigabit Router User Manual 
21 
To realize roaming in the coverage range of the wireless router by a wireless client, 
you need to set the APs properly as follows: 
  Set the same SSID for different APs. 
  The SSIDs of all the computers and PDAs should be consistent with that of 
APs.  
  All the BSSs must use the same wireless channel. 
  If the encryption function is enabled, all wireless routers must be configured 
with the same encryption mode and encryption key for establishing connection. 
  Wireless routers must keep coverage of uninterrupted wireless signals in the 
whole operation environment. Hence, please put wireless routers to the 
appropriate places.

5   TCP/IP Settings and Wireless Connection 
Introduction 
5.1   TCP/IP Settings 
By default, the LAN IP address of the wireless router is 192.168.1.1, the subnet 
mask is 255.255.255.0, and the DHCP server is enabled. 
It is recommended to set the network adapter to Obtain an IP address 
automatically. Then, your PC obtains the TCP/IP settings, including the IP 
address, subnet mask, gateway, and DNS address automatically through the 
wireless router. If you know the settings of the current LAN interface, you can 
manually set the TCP/IP properties of the network adapter, so that your PC can 
communicate with the wireless router. 
To manually set the network adapter, do as follows: 
Step 1  Right-click the icon of My Network Places and choose Properties from 
the menu. The Network Connections window appears. 

              SMART/RG SR400ac 802.11ac Gigabit Router User Manual 
23 
Step 2  Right-click the network adapter icon and choose Properties from the 
menu. The Local Area Connections Properties window appears. 
  Note:  
If multiple network cards are installed on your PC, a window other than the 
Local Area Connections Properties window may appears. 
Step 3  Double-click Internet Protocol (TCP/IP) and the Internet Protocol 
(TCP/IP) Properties window appears. 

              SMART/RG SR400ac 802.11ac Gigabit Router User Manual 
24 
Step 4  Select Use the following IP address and enter the IP address of the 
network adapter. The IP address must be 192.168. 1.X (X is a number in 
the range of 2 to 254). If you want to access the Internet through a 
wireless router, you need to enter the default gateway and IP address of 
the DNS server correctly. 

              SMART/RG SR400ac 802.11ac Gigabit Router User Manual 
25 
Step 5  Set the subnet mask and click OK. 
Step 6  After setting, you can ping the default IP address of the wireless router, 
to check whether the current connection between the PC and the 
wireless router is normal. Choose Start > Run from the desktop and 
enter ping 192.168.1.1. See the following figure: 

              SMART/RG SR400ac 802.11ac Gigabit Router User Manual 
26 
  Note:  
192.168.1.1 in the ping command is the default IP address of the LAN interface. 
If the IP address changes, enter the current IP address instead. 
Step 7  If the PC can ping through the default IP address of the wireless router, 
the following page appears, indicating that the connection between your 
PC and the wireless router is normal. 
5.2   Wireless Connection Introduction 
By default, the AP function of the wireless router is enabled. If you use a wireless 
network adapter, do as follows to establish the connection: 

              SMART/RG SR400ac 802.11ac Gigabit Router User Manual 
27 
Step 1  Enable the wireless network adapter on your PC and ensure that the 
Wireless Zero Configuration tool is available. Right-click the Wireless 
Network Connection icon and choose View Available Wireless 
Networks from the menu. 
Step 2  In the Wireless Network Connection page, click Refresh network list 
and the network list is refreshed. The default SSID of the wireless router 
is Broadcom24 (2.4G) or Broadcom58 (5.8G). Select the wireless 
router that you want to connect and click Connect. The default wireless 
security mode is None, and you can connect the wireless router directly 
without the encryption key in this mode. If the wireless router is 
encrypted, you need to enter the correct key to connect to the wireless 
router. 
Step 3  If you are not sure of the available SSID, please log in to the Web page 
of the wireless router, and view the SSID in the SSID page of the 
wireless settings. 

              SMART/RG SR400ac 802.11ac Gigabit Router User Manual 
28 
  Note: 
After your wireless network card connects to the wireless router successfully, 
usually, you should set the network adapter to Obtain an IP address 
automatically. The configuration of wireless connection is now complete.

29 
6   Logging In to the Web Page 
Run the Internet Explorer (IE), enter http://192.168.1.1/ (the default IP address of 
the wireless router) in the address bar, and press Enter. 
In the pop-up window, enter the user name and password, and click Login. 
  Note: 
The default user name is void and the default password is admin. 
After logging in to the Web page, you can view, configure and modify the router 
settings. To make the settings and changes take effect, you need to reboot the 
wireless router sometimes. 
  Caution: 
If you are managing the wireless router through the Web page, do not cut 
off the power supply. Otherwise, the device may be damaged.
