Archer A20 V1 User Guide

1. Change the LAN Settings

The router is preset with a default LAN IP, which you can use to log in to its web management page. The LAN IP address together with the Subnet Mask also defines the subnet that the connected devices are on. If the IP address conflicts with another device on your local network or your network requires a specific IP subnet, you can change it.

1.Visit, and log in with your TP-Link ID or the password you set for the router.

2.Go to Advanced > Network > LAN.

3.Type in a new IP Address appropriate to your needs. And leave the Subnet Mask as the default settings.

4.Click Save.

Note: If you have set the Virtual Server, DMZ or DHCP address reservation, and the new LAN IP address is not in the same subnet with the old one, then you should reconfigure these features.

2. Set Up Link Aggregation

The Link Aggregation feature combines two ports together to make a single highbandwidth data path, thus sustaining a higher-speed and more stable wired network.

1.Visit, and log in with your TP-Link ID or the password you set for the router.

2.Go to Advanced > Network > LAN.

3.Tick the Enable checkbox to enable Link Aggregation.

4.Specify two ports for Link Aggregation.

Note: LAN ports used for IPTV or WAN aggregation cannot be selected.

5.Click Save.

3. Configure to Support IPTV Service

I want to:

Configure IPTV setup to enable Internet/IPTV/Phone service provided by my internet service provider (ISP).

How can I do that?

1.Visit, and log in with your TP-Link ID or the password you set for the router.

2.Go to Advanced > Network > IPTV.

3.If your ISP provides the networking service based on IGMP technology, e.g., British Telecom(BT) and Talk Talk in UK:

1 )Tick the IGMP Proxy checkbox and select the IGMP Version, either V2 or V3, as required by your ISP.

2 )Click Save.

3 )After configuring IGMP proxy, IPTV can work behind your router now. You can connect your set-top box to any of the router’s Ethernet port.

If IGMP is not the technology your ISP applies to provide IPTV service:

1 )Tick Enable IPTV.

2 )Select the appropriate Mode according to your ISP.

Select Bridge if your ISP is not listed and no other parameters are required.

Select Custom if your ISP is not listed but provides necessary parameters.

3 )After you have selected a mode, the necessary parameters, including the LAN port for IPTV connection, are predetermined. If not, select the LAN type to determine which port is used to support IPTV service.

4 )Click Save.

5 )Connect the set-top box to the corresponding LAN port which is predetermined or you have specified in Step 3.


Your IPTV setup is done now! You may need to configure your set-top box before enjoying your TV.

Tips: Qos and IPTV cannot be enabled at the same time.

4. Specify DHCP Server Settings

By default, the DHCP (Dynamic Host Configuration Protocol) Server is enabled and the router acts as a DHCP server; it dynamically assigns TCP/IP parameters to client devices from the IP Address Pool. You can change the settings of the DHCP Server if necessary, and you can reserve LAN IP addresses for specified client devices.

1.Visit, and log in with your TP-Link ID or the password you set for the router.

2.Go to Advanced > Network > DHCP Server.

To specify the IP address that the router assigns:

1.Tick the Enable DHCP Server checkbox.

2.Enter the starting and ending IP addresses in the IP Address Pool.

3.Enter other parameters if the ISP offers. The Default Gateway is automatically filled in and is the same as the LAN IP address of the router.

4.Click Save.

To reserve an IP address for a specified client device:

1.Click Add in the Address Reservation section.

2.Click View Exsiting Devices or enter the MAC address of the client device.

3.Enter the IP address to reserve for the client device.

4.Enter the Description for this entry.

5.Tick the Enable This Entry checkbox and click OK.

5. Set Up a Dynamic DNS Service Account

Most ISPs assign a dynamic IP address to the router and you can use this IP address to access your router remotely. However, the IP address can change from time to time and you don’t know when it changes. In this case, you might apply the DDNS (Dynamic Domain Name Server) feature on the router to allow you and your friends to access your router and local servers (FTP, HTTP, etc.) using a domain name without checking and remembering the IP address.

Note: DDNS does not work if the ISP assigns a private WAN IP address (such as 192.168.1.x) to the router.

1.Visit, and log in with your TP-Link ID or the password you set for the router.

2.Go to Advanced > Network > Dynamic DNS.

3.Select the DDNS Service Provider: TP-Link, NO-IP or DynDNS. It is recommended to select TP-Link so that you can enjoy TP-Link’s superior DDNS service. Otherwise, please select NO-IP or DynDNS. If you don’t have a DDNS account, you have to register first by clicking Go to register.

Note: To enjoy TP-Link’s DDNS service, you have to log in with a TP-Link ID. If you have not logged in with one, click Log in.

4.Click Register in the Domain Name List if you have selected TP-Link, and enter the Domain Name as needed.

If you have selected NO-IP or DynDNS, enter the username, password and domain name of your account.

5.Click Login and Save.

Tips: If you want to use a new DDNS account, please click Logout first, and then log in with a new account.

6. Create Static Routes

Static routing is a form of routing that is configured manually by a network administrator or a user by adding entries into a routing table. The manually-configured routing information guides the router in forwarding data packets to the specific destination.

I want to:

Visit multiple networks and servers at the same time.

For example, in a small office, my PC can surf the internet through Router A, but I also want to visit my company’s network. Now I have a switch and Router B. I connect the devices as shown in the following figure so that the physical connection between my PC and my company’s server is established. To surf the internet and visit my company’s network at the same time, I need to configure the static routing.

How can I do that?

1.Change the routers’ LAN IP addresses to two different IP addresses on the same subnet. Disable Router B’s DHCP function.

2.Visit, and log in with your TP-Link ID or the password you set for Router A.

3.Go to Advanced > Network > Static Routing.

4.Click Add and finish the settings according to the following explanations:

Network Destination: The destination IP address that you want to assign to a static route. This IP address cannot be on the same subnet with the WAN IP or LAN IP of Router A. In the example, the IP address of the company network is the destination IP address, so here enter

Subnet Mask: Determines the destination network with the destination IP address. If the destination is a single IP address, enter; otherwise, enter the subnet mask of the corresponding network IP. In the example, the destination network is a single IP, so here enter

Default Gateway: The IP address of the gateway device to which the data packets will be sent. This IP address must be on the same subnet with the router’s IP which sends out data. In the example, the data packets will be sent to the LAN port of Router B and then to the Server, so the default gateway should be

Interface: Determined by the port (WAN/LAN) that sends out data packets. In the example, the data are sent to the gateway through the LAN port of Router A, so LAN should be selected.

Description: Enter a description for this static routing entry.

5.Click OK.

6.Check the System Routing Table below. If you can find the entry you’ve set, the static routing is set successfully.


Open a web browser on your PC. Enter the company server’s IP address to visit the company network.
