Connect the Hardware

This chapter contains the following sections:
• Position Your Router
• Connect Your Router

 

Position Your Router

With the router, you can access your network from anywhere within the wireless network coverage. However, the wireless signal strength and coverage vary depending on the actual environment of your router. Many obstacles may limit the range of the wireless signal, for example, concrete structures or thick walls.

For your security and best Wi-Fi performance, please:

• The product should not be located in a place where it will be exposed to moisture or excessive heat.
• Place the router in a location where it can be connected to multiple devices as well as to a power source.
• Make sure the cables and power cord are safely placed out of the way so they do not create a tripping hazard.
• The router can be placed on a shelf or desktop.
• Keep the router away from devices with strong electromagnetic interference, such as Bluetooth devices, cordless phones and microwaves.

 

Connect Your Router

The Router provides four working modes: Wireless Router, WISP, Range Extender andAccess Point. You can choose the mode to better suit your network needs and follow the guide to complete the configuration.

Wireless Router Mode

1.  Follow the steps below to connect your router.

If your internet connection is through an Ethernet cable from the wall instead of through a DSL / Cable / Satellite modem, connect the Ethernet cable directly to the router’s WAN port, and then follow Step 4 and 5 to complete the hardware connection.

hardware connection of Wireless Router Mode

1 ) Turn off the modem, and remove the backup battery if it has one.
2 ) Connect the modem to the router’s WAN port with an Ethernet cable.
3 ) Turn on the modem, and then wait about 2 minutes for it to restart.
4 ) Connect the power adapter to the router.

2. Connect your computer or wireless devices to the router.

• Method 1: Wired

• Your computer might not recognize any DNS server addresses. Please manually configure the DNS server.

1) Go to Advanced > Network > DHCP Server.
2) Enter 8.8.8.8 as Primary DNS, click SAVE.
 Tips: 8.8.8.8 is a safe and public DNS server operated by Google.

Enter 8.8.8.8 as Primary DNS

• Restart the modem and the router.
1) Power off your modem and router, and leave them off for 1 minute.
2) Power on your modem first, and wait about 2 minutes until it gets a solid cable or Internet light.
3) Power on the router.
4) Wait another 1 or 2 minutes and check the internet access.

• Reset the router to factory default settings and reconfigure the router.

• Upgrade the firmware of the router.

• Check the TCP/IP settings on the particular device if all other devices can get internet from the router.

As the picture below shows, if the IP Address is 0.0.0.0, please try the methods below and try again:

the IP Address is 0.0.0.0

• Make sure the physical connection between the router and the modem is proper.

• Clone the MAC address of your computer.
1) Visit http://tplinkwifi.net, and log in with the password you set for the router.
2) Go to Internet or Advanced > Network > Internet and focus on the MAC Clone section.
3) Choose an option as needed (enter the MAC address if Use Custom MAC Address is selected), and click SAVE.

Use Custom MAC Address is selected

Tips:
Some ISP will register the MAC address of your computer when you access the internet for the first time through their Cable modem, if you add a router into your network to share your internet connection, the ISP will not accept it as the MAC address is changed, so we need to clone your computer’s MAC address to the router.
The MAC addresses of a computer in wired connection and wireless connection are different.

• Modify the LAN IP address of the router.
Note: 
Most TP-Link routers use 192.168.0.1/192.168.1.1 as their default LAN IP address, which may conflict with the IP range of your existing ADSL modem/router. If so, the router is not able to communicate with your modem and you can’t access the internet. To resolve this problem, we need to change the LAN IP address of the router to avoid such conflict, for example, 192.168.2.1. 
1) Visit http://tplinkwifi.net, and log in with the password you set for the router.
2) Go to Advanced > Network > LAN.
3) Modify the LAN IP address as the follow picture shows. Here we take 192.168.2.1 as an example.
4) Click SAVE.

Modify the LAN IP address

• Restart the modem and the router.
1) Power off your modem and router, and leave them off for 1 minute.
2) Power on your modem first, and wait about 2 minutes until it get a solid cable or Internet light.
3) Power on the router.
4) Wait another 1 or 2 minutes and check the internet access.

Double check the internet connection type.
1) Confirm your internet connection type, which can be learned from the ISP.
2) Visit http://tplinkwifi.net, and log in with the password you set for the router.
3) Go to Advanced > Network > Internet.
4) Select your Internet Connection Type and fill in other parameters.
5) Click SAVE.

Select your Internet Connection Type and fill in other parameters

6) Restart the modem and the router again.

• Please upgrade the firmware of the router.
If you’ve tried every method above but still cannot access the internet, please contact the technical support.

 

Q5. What should I do if I can’t find my wireless network or I cannot connect the wireless network?

If you fail to find any wireless network, please follow the steps below:
• Make sure the wireless function of your device is enabled if you’re using a laptop with built-in wireless adapter. You can refer to the relevant document or contact the laptop manufacturer.
• Make sure the wireless adapter driver is installed successfully and the wireless adapter is enabled.

  • On Windows 7
  1. If you see the message No connections are available, it is usually because the wireless function is disabled or blocked somehow.
  2. Click Troubleshoot and windows might be able to fix the problem by itself.
  • On Windows XP
  1. If you see the message Windows cannot configure this wireless connection, this is usually because windows configuration utility is disabled or you are running another wireless configuration tool to connect the wireless.
  2. Exit the wireless configuration tool (the TP-Link Utility, for example).
  3. Select and right click on My Computer on desktop, select Manage to open Computer Management window.

If you can find other wireless network except your own, please follow the steps below:

• Check the WLAN LED indicator on your wireless router/modem.
• Make sure your computer/device is still in the range of your router/modem. Move it  closer if it is currently too far away.
• Go to Wireless or Advanced > Wireless > Wireless Settings, and check the wireless settings. Double check your wireless Network Name and SSID is not hided.

If you can find your wireless network but fail to connect, please follow the steps below:

• Authenticating problem/password mismatch:

1) Sometimes you will be asked to type in a PIN number when you connect to the wireless network for the first time. This PIN number is different from the Wireless Password/Network Security Key, usually you can only find it on the label of your router.

Sometimes you will be asked to type in a PIN number

2) If you cannot find the PIN or PIN failed, you may choose Connecting using a security key instead, and then type in the Wireless Password/Network Security Key.

3) If it continues to show note of Network Security Key Mismatch, it is suggested to confirm the wireless password of your wireless router.
Note: Wireless Password/Network Security Key is case sensitive.

• Windows unable to connect to XXXX / Can not join this network / Taking longer than usual to connect to this network:

  • Check the wireless signal strength of your network. If it is weak (1~3 bars), please move the router closer and try again.
  • Change the wireless Channel of the router to 1, 6 or 11 to reduce interference from other networks.
