人们将继续在家工作，并大量在家上课。这意味着在您家中的更多地方有更多的连接设备。这也意味着更多的人正在共享互联网连接。
此外，这可能意味着您需要在家中的某些部分使用以前不需要的有线或无线网络。我们将向您展示连接两个路由器的几种方法，以使您的家庭网络更加健壮(make your home network more robust)。
为什么要设置第二个路由器(Router)？
有几种方法可以将第二个无线路由器添加到您的家庭网络。您可以将其用作接入点或中继器来扩展无线覆盖范围。您可以设置一个单独的网络供客人使用。或者，您可以将第二个路由器用作交换机，为您的网络添加更多以太网端口。
在家(Home)设置第二个路由器(Router)的要求
并非每个 Wi-Fi 路由器都可以设置为第二个路由器以扩展无线范围或作为接入点 (AP)。这是您需要的：
- 管理员(Administrator)访问您的主路由器和辅助路由器
- 要设置为 AP 或交换机，请使用以太网(Ethernet)电缆连接两个路由器
如果您的第二个路由器因为较旧而无法在这些不同模式下使用，请寻找固件更新。此更新可能会扩展其功能。
在本教程中，我们使用华硕 RT-N300(Asus RT-N300)作为我们的第二个 Wi-Fi 路由器。您的路由器可能不同。但是，无论是D-Link、tp-Link、Linksys、Netgear还是许多可用的优秀路由器型号(good router models)中的任何一种，都适用相同的概念。
如何将第二个 Wi-Fi路由器(Router)设置为无线接入点(Wireless Access Point)
如果您的家中有以太网线，(home is wired for Ethernet)并且您希望家庭网络中的任何地方都具有出色的无线覆盖和互联网接入，请考虑使用第二个路由器作为接入点 (AP)。通过辅助路由器和主路由器之间的快速、稳定的以太网(Ethernet)连接，
您将获得出色的 Wi-Fi 覆盖。
- 在第二台路由器上，登录并转至Administration > Operation Mode并选择Access Point Mode，然后选择Save。
- 此时，让路由器设置局域网IP(LAN IP)并自动连接到域名服务器(Domain Name Server)（DNS）。然后选择下一步(Next)继续。
- 在Wireless Setting中，为 Do you want to use previous wireless security settings?保留默认选择Yes 这使您可以使用与主路由器相同的SSID(SSID)和密码连接到 AP ，从而在移动时实现两者之间的无缝转换。
如果要使用不同的SSID和密码创建访客网络，请选择否，然后根据需要更改值。访客网络不会与您的个人网络完全分离。这只是意味着您不必共享您的个人密码。选择应用(Select Apply)以继续。
路由器应用设置。
- 将路由器 2的WAN端口直接或通过有线家庭网络连接到路由器 1 上的LAN端口。(LAN)现在你有一个AP。

如何设置第二个 Wi-Fi路由器(Router)以扩展范围(Range)
无线路由器通常设置在房子的一端，服务进入家庭。然后家里的远端 Wi-Fi 信号很差或没有。在您家中部附近的某处设置第二个 Wi-Fi 路由器作为 Wi-Fi 范围扩展器将为您在家中的任何地方提供无线连接，而无需与第一个路由器建立有线以太网(Ethernet)连接。
幸运的是，许多新路由器都有一个向导过程来将其设置为无线范围扩展器。例如，华硕 RT-N300(Asus RT-N300)在初始设置时提供了一个简单的中继器模式选项。要估计第二个无线路由器的放置位置，请使用应用程序测量无线信号强度并找到它开始下降的位置。退回几英尺以获得更好的信号强度，这是放置它的好地方。
- 选择中继器模式，然后选择下一步。
请注意指向设备发现实用程序(Device Discovery Utility)的链接。该链接已失效，但我们发现了一个指向 Device Discovery Utility 的新链接(link to the Device Discovery Utility)。iPhone 和 iPad也有适用于 iOS 的 ASUS Device Discovery 应用程序。(ASUS Device Discovery app for iOS)在将路由器设置为无线中继器后，
设备发现实用程序可以更简单、更轻松地找到路由器的 IP 地址。(Device Discovery Utility)
- 该向导扫描附近的无线信号并显示其网络。从列表中选择您的。输入用于连接到 Wi-Fi 网络的密码，然后选择连接(Connect)。
- 该向导设置静态 IP 地址(static IP address)并收集本地网络的子网掩码和默认网关。这些设置很好，保持原样并选择Next。
- 无线设置(Wireless Setting)默认值也适用于大多数人。保持原样并选择Apply。这样一来，您的无线密码将通过任一路由器将您连接到家庭网络。
路由器现在连接到主 Wi-Fi 路由器。完成后不会返回路由器管理页面，因为第二台路由器的IP地址已经改变。这就是您需要Device Discovery Utility的地方。
- 打开在步骤 1(Step 1)中下载的设备发现实用程序(Device Discovery Utility)以获取第二个路由器的新 IP 地址。在您的网络浏览器中输入该 IP 地址以访问路由器管理站点并登录。
- 转到Advanced Settings > Wireless并将漫游助手从禁用(Disable)切换到启用(Enable)。-70 dBm的默认RSSI设置适用于大多数情况。这意味着，当第二个路由器看到信号强度低于 -70 dBm 的设备时，它将与其断开连接。该设备现在可以尝试连接到您的主路由器，从而在两者之间实现无缝转换。这类似于您在开车时手机通话从一个塔传递到另一个塔的方式。选择应用(Apply)。
可能需要几分钟才能完成。现在，您的第二个路由器周围有了无线覆盖。
如何设置第二个路由器(Router)作为(Act)交换机
大多数家庭网络都有一个组合调制解调器/路由器，背面有 4 个或 5 个以太网端口，用于有线连接。(Ethernet)一旦这些端口已满，而您仍需要有线连接，您会怎么做？将路由器用作交换机。您也可以为此使用以太网(Ethernet)路由器。
- (Connect)使用以太网(Ethernet)电缆将路由器 1连接到路由器 2 。一端插入LAN端口或第一个路由器，另一端插入路由器上的LAN端口。忽略WAN端口。使用另一条以太网(Ethernet)电缆将第二个路由器连接到您的计算机。
- 登录(Log)到第一个路由器并记下它所覆盖的 IP 范围。在本例中，子网为 192.168.2.0/24，可提供的 IP 地址范围为 192.168.2.10 到 192.168.2.254。以 1 到 9 结尾的 IP 地址对DHCP(DHCP)服务器不可用，因此它们可以作为静态 IP 地址提供，而不会导致网络中的 IP 冲突。
- 连接到第二个路由器的管理页面并导航到Advanced Settings > LAN > LAN IP为了更容易找到并再次连接到路由器，请给路由器一个与第一个路由器不同但在同一子网中的静态 IP。我们使用的是 192.168.2.2。确保子网掩码与第一个路由器的子网掩码匹配。选择应用(Select Apply)。您需要在浏览器的地址栏中输入 192.168.2.2 才能重新连接。
- 移动到DHCP 服务器(DHCP Server)选项卡并禁用DHCP。只有路由器 1 应充当DHCP服务器并分配 IP 地址。
- 如果可能，请关闭无线访问。转到Wireless > Professional并将启用无线电设置为否。如果您的路由器没有该选项，请通过(Enable Radio)隐藏服务集标识符 (SSID) （(hiding the Service Set Identifier (SSID))也称为您的Wi-Fi的名称）来尽可能地保护无线访问，并设置可笑的强访问密码。这可以防止任何人意外或故意将其作为无线设备连接到它。现在，您可以通过以太网(Ethernet)将更多设备连接到您的家庭网络，只需将它们插入剩余的LAN端口即可。
连接起来
现在，您至少可以在电子设备堆中使用一件东西，并且您的家庭网络会更好。您对使用第二个路由器还有其他想法吗？让我们知道。
How to Setup a Second Router on Your Home Network
Pеople will continue to work from home and attend classes from home in great numbers. That meаns more connected devices in more places in your home. It also means more peoplе are sharing the internet connection.
Also, it may mean you need a wired or wireless network in parts of your home that you previously didn’t. We’ll show you a few ways to connect two routers to make your home network more robust.
Why Would I Set Up a Second Router?
There are several ways to add a second wireless router to your home network. You could use it as an access point or repeater to extend wireless coverage. You could set up a separate network for guests to use. Or you could use the second router as a switch to add more Ethernet ports to your network.
Requirements for Setting Up a Second Router at Home
Not every Wi-Fi router can be set up as a second router for extending wireless range or as an access point (AP). Here’s what you need:
- Administrator access to your primary and secondary router
- To set up as an AP or switch, an Ethernet cable to connect the two routers
If your second router isn’t capable of being used in these different modes because it’s older, look for a firmware update. The update may expand its capabilities.
For this tutorial, we’re using an Asus RT-N300 as our second Wi-Fi router. Your routers are likely different. However, the same concepts apply whether it’s a D-Link, tp-Link, Linksys, Netgear, or any of the many good router models available.
How to Setup a Second Wi-Fi Router as a Wireless Access Point
If your home is wired for Ethernet and you want excellent wireless coverage and internet access everywhere in your home network, consider using the second router as an access point (AP). You’ll get great Wi-Fi coverage with a fast, stable Ethernet connection between your secondary router to your primary router.
- On the second router, log in and go to Administration > Operation Mode and select Access Point Mode, then Save.
- At this point, let the router set the LAN IP and connect to the Domain Name Server (DNS) automatically. Then select Next to continue.
- In Wireless Setting, leave the default of Yes selected for Do you want to use the previous wireless security settings? This lets you connect to the AP with the same SSID and password as the main router, making for a seamless transition between the two when moving around.
If you want to make a guest network with a different SSID and password, select No and then change the values as needed. The guest network wouldn’t be completely separate from your personal network; it would just mean you don’t have to share your personal password. Select Apply to continue.
The router applies the settings.
- Connect the WAN port of router 2 to a LAN port on router 1, either directly or through the wired home network. Now you have an AP.

How to Setup a Second Wi-Fi Router to Extend the Range
Often the wireless router is set up on one end of the house, where services come into the home. Then the far end of the home has poor or no Wi-Fi signal. Setting up a second Wi-Fi router as a Wi-Fi range extender somewhere near the middle of your house will give you wireless connection anywhere in your home, without a wired Ethernet connection to the first router.
Fortunately, many new routers have a wizard process to set it up as a wireless range extender. For example, the Asus RT-N300 provides a simple repeater mode option on initial setup. To estimate where to place the second wireless router, use an app to measure the wireless signal strength and find where it starts to drop. Go back a few feet into better signal strength and that’s a good spot to put it.
- Select Repeater mode, then Next.
Note the link to a Device Discovery Utility. That link is dead, however we found a new link to the Device Discovery Utility. There is also an ASUS Device Discovery app for iOS for iPhones and iPads. The Device Discovery Utility makes it simpler and easier to find the router’s IP address after it’s set up as a wireless repeater.
- The wizard scans nearby wireless signals and shows their networks. Select yours from the list. Enter the password used to connect to your Wi-Fi network, then select Connect.
- The wizard sets a static IP address and collects the local network’s subnet mask and default gateway. These settings are fine, leave them as they are and select Next.
- The Wireless Setting defaults are fine for most people as well. Leave them as they are and select Apply. This makes it so that your wireless password will connect you to your home network through either router.
The router now connects to the main Wi-Fi router. When this is complete, it doesn’t return to the router management page, because the second router’s IP address has changed. This is where you need the Device Discovery Utility.
- Open the Device Discovery Utility downloaded in Step 1 to get the new IP address of your second router. Enter that IP address into your web browser to get to the router management site and log in.
- Go to Advanced Settings > Wireless and switch Roaming assistant from Disable to Enable. The default RSSI setting of -70 dBm is good for most situations. That means that when the second router sees a device with a signal strength less than -70 dBm it will disconnect from it. The device can now try to connect to your primary router, giving a seamless transition between the two. It’s similar to how your cellphone call gets passed from tower to tower as you’re driving.Select Apply.
It can take a few minutes to finish. You now have wireless coverage around your second router.
How to Setup a Second Router to Act as a Switch
Most home networks have a combination modem/router with 4 or 5 Ethernet ports on the back for wired connections. Once those ports are full, and you still want wired connections, what do you do? Use your router as a switch. You can also use an Ethernet router for this.
- Connect router 1 to router 2 with an Ethernet cable. One end is plugged into a LAN port or the first router and the other to a LAN port on the router. Ignore the WAN port. Use another Ethernet cable to connect the second router to your computer.
- Log in to the first router and take note of the IP range it covers. In this example, the subnet is 192.168.2.0/24 and the range of IP addresses that can be given is from 192.168.2.10 to 192.168.2.254. IP addresses ending in 1 to 9 aren’t available to the DHCP server so they can be given as static IP addresses and not cause an IP conflict in the network.
- Connect to the second router’s management page and navigate to Advanced Settings > LAN > LAN IP To make it easier to find and connect to the router again, give the router a static IP that’s different from your first router, but in the same subnet. We’re using 192.168.2.2. Make sure the subnet mask matches the first router’s subnet mask. Select Apply. You’ll need to enter 192.168.2.2 in the browser’s location bar to reconnect.
- Move to the DHCP Server tab and disable DHCP. Only router 1 should act as a DHCP server and assign IP addresses.
- If possible, turn off wireless access. Go to Wireless > Professional and set Enable Radio to No. If your router doesn’t have that option, secure the wireless access as much as possible by hiding the Service Set Identifier (SSID) also known as the name of your Wi-Fi, and setting ridiculously strong access passwords. This prevents anyone from connecting to it as a wireless device, accidentally or on purpose. Now you can connect more devices via Ethernet to your home network by plugging them into the remaining LAN ports.
