如何使用简单的接入点扩展您的Wi-Fi网络
Last week we showed you how to extend your network without wires, this week we’re looking at how you can use use an existing hardwire network to easily and quickly extend your wireless network using simple access points.
上周，我们向您展示了如何在不使用电线的情况下扩展网络，本周，我们在研究如何使用现有的硬线网络通过简单的接入点轻松快速地扩展无线网络。
After we published our guide How To Extend Your Wireless network with Tomato-Powered Routers, we received a variety of reader questions regarding other tips and tricks one could use to extend a wireless network. Bill wrote in with the following question which echoes quite a few similar emails:
在我们发布了指南《如何用番茄供电的路由器扩展无线网络》之后，我们收到了许多读者对其他可以用来扩展无线网络的提示和技巧的问题。 比尔写了以下问题，回响了很多类似的电子邮件：
I read and followed your guide last Tuesday. Everything worked as promised, but I’ve noticed the secondary router seems a little flaky. Is there a more bare-bones way to go about this technique than setting up the Tomato routers via WDS as you have us do in the tutorial? My house is wired with Ethernet but, alas, very few of my devices actually use hard wire anymore. What can I do? All my routers are running current releases of TomatoUSB.
上周二，我阅读并遵循了您的指南。 一切都按承诺进行，但我注意到辅助路由器似乎有些松动。 除了本教程中介绍的通过WDS设置Tomato路由器之外，还有没有比这更简单的方法了？ 我的房子用以太网连接，但可惜的是，我的设备实际上很少使用硬线了。 我能做什么？ 我所有的路由器都在运行当前版本的TomatoUSB。
If Bill didn’t have the existing LAN in place, we’d have to tell him to try a different firmware (like DD-WRT) that allows for true Wi-Fi repeating. Since he has an existing hardwired Ethernet LAN, however, he’s in luck.
如果Bill没有现成的LAN，我们必须告诉他尝试使用其他固件(例如DD-WRT)来实现真正的Wi-Fi中继。 但是，由于他拥有现有的有线以太网LAN，因此很幸运。
In a situation with no Ethernet network, you have to rely completely on wireless technology to link the access points together (as we did when we used WDS to link the two Tomato routers together last week). When you have a hardwired network, however, things get radically easier as you can use the Ethernet as a backbone for the network and convert the secondary routers to simple access points that require little effort to configure and deploy.
在没有以太网的情况下，您必须完全依靠无线技术将访问点链接在一起(就像我们上周使用WDS将两个Tomato路由器链接在一起时所做的那样)。 但是，当您拥有有线网络时，事情就变得非常简单，因为您可以将以太网用作网络的骨干网，并将辅助路由器转换为简单的访问点，而无需进行任何配置和部署。
What specifically do you gain by using this technique over the previous technique? In our prior tutorial we showed you how to make a mesh of Wi-Fi routers. While that’s a great solution if you don’t have any hard wire to connect them, it does have its short comings as it requires a lot of configuration and a Wi-Fi mesh protocol that can introduce latency and reduced bandwidth. The technique we’re about to outline simply adds Wi-Fi access points to any open Ethernet connection on your hard-wired LAN—no fancy configuration or Wi-Fi Voodoo required.
通过使用该技术，您将比以前的技术有什么特别的收获？ 在之前的教程中，我们向您展示了如何制作Wi-Fi路由器网格。 如果您没有任何硬线连接它们是一个很好的解决方案，但它确实有其不足之处，因为它需要大量的配置和Wi-Fi网状协议，可以引入延迟并减少带宽。 我们将要概述的技术只是将Wi-Fi接入点添加到硬线LAN上的任何开放式以太网连接中，而无需花哨的配置或Wi-Fi Voodoo。
你需要什么 (What You’ll Need)
For this tutorial you need the following things:
对于本教程，您需要以下内容：
- One primary router 一台主路由器
- One or more secondary routers一台或多台辅助路由器
- One physical port on the primary router and one direct Ethernet cable link for each secondary router主路由器上有一个物理端口，每个辅助路由器有一个直接的以太网电缆链路
That’s all you need! You don’t even, technically, need any fancy after market firmware like Tomato or DD-WRT. That merits repeating. Although we’re going to be using Tomato-powered routers, you can use just about any stock Wi-Fi router around without flashing the firmware. Unlike other Wi-Fi tutorials we’ve shared that involve deep mucking around in the guts of a customized router, this tutorial simply requires that you are able to change the basic Wi-Fi access point settings on your secondary routers.
这就是您所需要的！ 从技术上讲，您甚至不需要市场固件如Tomato或DD-WRT。 值得重复。 尽管我们将使用番茄供电的路由器，但您几乎可以使用任何库存的Wi-Fi路由器，而无需刷新固件。 与我们共享的其他Wi-Fi教程不同，后者涉及对自定义路由器的深入了解，本教程仅要求您能够更改辅助路由器上的基本Wi-Fi接入点设置。
入门：重置辅助路由器 (Getting Started: Resetting The Secondary Router)
For the purposes of clarity, we’re going to refer to the primary router as the “Primary Router” and the secondary router as the “Secondary Router”. Simple, yes, but it ensures we’re all on the same page and not applying the settings to the wrong device.
为了清楚起见，我们将主要路由器称为“主要路由器”，将辅助路由器称为“辅助路由器”。 可以，很简单，但是可以确保我们都在同一页面上，并且不会将设置应用到错误的设备上。
Again, although we’re using TomatoUSB these instructions can be applied to nearly every router on the market. Read over the whole guide and then apply the steps, slightly adapted for different menu structures, to your router.
同样，尽管我们正在使用TomatoUSB，但这些指令几乎可以应用于市场上的每个路由器。 阅读整个指南，然后将略微适合不同菜单结构的步骤应用于路由器。
The first thing you want to do is reset your Secondary Router (not your Primary Router) so you can work with a clean slate. Plug your Secondary Router directly into a desktop or laptop machine via the Ethernet port. Navigate to Administration –> Configuration –> Restore Default Configuration and select “Erase all data in NVRAM memory (thorough)”. Click OK.
您要做的第一件事是重置辅助路由器(而不是主路由器)，这样您就可以处理干净了。 通过以太网端口将辅助路由器直接插入台式机或便携式计算机。 导航到管理–>配置–>恢复默认配置，然后选择“(彻底)擦除NVRAM内存中的所有数据”。 单击确定。
The default login/password after a clean wipe in Tomato is admin/admin. You should change the password immediately by navigating to Administration -> Admin Access. While we’re in the Admin Access menu we can change two things. First, change the color scheme of Tomato to easily distinguish between default Tomato installation and secondary access points.
彻底清除Tomato中的默认登录名/密码是admin / admin。 您应该通过导航到管理->管理员访问来立即更改密码。 在“管理员访问权”菜单中时，我们可以更改两件事。 首先，更改Tomato的配色方案，以轻松地区分默认的Tomato安装和辅助访问点。
The color setting is found near the top of the Admin Access page under Web Admin -> Color Scheme. We selected blue. To change the password scroll down to the bottom and plug in a new password in the Password section. Makes sure to click Save at the bottom or your changes will not be applied. Tomato will, immediately after you click Save, prompt you to login again. Use login: admin and password: whatever new password you just created.
颜色设置位于Web管理员->配色方案下的“管理员访问”页面顶部附近。 我们选择了蓝色。 要更改密码，请向下滚动至底部，然后在“密码”部分插入新密码。 确保单击底部的“保存”，否则您的更改将不会应用。 单击“保存”后，Tomato将立即提示您再次登录。 使用登录名：admin和密码：您刚刚创建的新密码。
配置辅助路由器 (Configuring The Secondary Router)
Once you’ve reset the Secondary Router and assigned a new password it’s time to configure it. We only need to make a handful of changes to the Secondary Router, and (in TomatoUSB at least) they can all be made on a single page.
重置辅助路由器并分配了新密码后，就可以对其进行配置了。 我们只需要对辅助路由器进行一些更改，并且(至少在TomatoUSB中)它们都可以在单个页面上进行。
Navigate to Basic –> Network within the GUI of the Secondary Router. We need to make a few minor changes here. First you need to toggle WAN / Internet to Static. There’s no need to change anything else in this sub-section.
导航到辅助路由器的GUI中的“基本”->“网络”。 我们需要在此处进行一些小的更改。 首先，您需要将WAN / Internet切换为静态。 在此小节中无需更改任何其他内容。
Next you need to change the Router IP Address. This can be any number that isn’t 1) the same as your Primary Router or 2) in the slate of assignable addresses used by your Primary Router’s DHCP server, such as 198.168.1.100-149. We simply switched ours to 192.168.1.2 to indicate it was the first of the secondary routers attached to our network.
接下来，您需要更改路由器IP地址。 它可以是与1)与您的主路由器相同或2)在主路由器的DHCP服务器使用的可分配地址列表中的任何数字，例如198.168.1.100-149。 我们只是简单地将其切换为192.168.1.2，以表明它是连接到我们网络的第一个辅助路由器。
Plug in the address of your Primary Router for the first Static DNS slot. Toggle off DHCP Server. The Secondary Router (and another other routers you may add in as future access points) need to refer to the Primary Router for their DNS settings and DHCP assignments in order to keep the setup simple and allow all network changes to be made easily from the Primary Router.
为第一个静态DNS插槽插入主路由器的地址。 切换DHCP服务器。 辅助路由器(以及您可能会添加为将来的接入点的其他其他路由器)需要参考主要路由器的DNS设置和DHCP分配，以保持设置简单并允许从主要路由器轻松进行所有网络更改路由器。
Next, you have the Wireless section. Within the Wireless section you need to make a few changes. First, ensure “Enable Wireless” is checked. Second, set Wireless Mode to “Access Point”. You can leave the Wireless Network Mode on Auto or enforce a specific mode (like G Only).
接下来，您有无线部分。 在“无线”部分中，您需要进行一些更改。 首先，确保选中“启用无线”。 其次，将无线模式设置为“接入点”。 您可以将“无线网络模式”保留为“自动”或强制执行特定模式(如“仅G”)。
The SSID should be the same as your other Wi-Fi access points (like the Primary Router). The security type, encryption type, and shared key should also be the same. Note: If you’re having trouble with the setup, it’s often useful to change the Secondary Router’s SSID to something like “wireless2” to distinguish it from “wireless” (the name of the Primary Router) and make signal testing and troubleshooting easier.
SSID应该与其他Wi-Fi接入点(例如主路由器)相同。 安全类型，加密类型和共享**也应该相同。 注意：如果您在设置时遇到麻烦，通常将辅助路由器的SSID更改为“ wireless2”，以将其与“无线”(主要路由器的名称)区分开来，使信号测试和故障排除更加容易，这通常很有用。
That said, the only place where the Wireless setup should differ from the Primary Router is the Channel selection. You want to select a channel for your access points that does not conflict with channels used by the Primary Router. Refer to this chart to select an appropriate channel:
也就是说，无线设置应与主路由器不同的唯一地方是信道选择。 您要为接入点选择一个与主路由器使用的信道不冲突的信道。 请参考此图表选择适当的渠道：
Let’s say that your Primary Router is using Channel 1. For your Secondary Router you can select Channel 6 or Channel 11 as a clear channel to minimize interference. For quick reference here are are some combinations you can use to keep the communication channels clear and leave space for a future access point:
假设您的主路由器正在使用信道1。对于次路由器，您可以选择信道6或信道11作为空闲信道，以最大程度地减少干扰。 为了快速参考，以下是一些组合，您可以使用它们来保持通信通道畅通并为将来的接入点留出空间：
- 1, 6, 11 1 6 1
- 2, 7, 12 2、7、12
- 3, 8, 13 3、8、13
Once you’ve finished selecting an open channel, click Save to commit all your changes to the Secondary Router. Once the changes are saved, unplug the Secondary Router from the computer you’ve been using to configure it and take it to the Ethernet jack you intend to plug it into. Run an Ethernet cable from the wall jack to one of the LAN ports on the Secondary Router (not the WAN port). Plug in the power cord to boot it up. Your secondary access point should now be online and accessible to the Wi-Fi devices nearby. As an added bonus you can also use the Secondary Router as a basic network switch—any nearby Ethernet dependent devices, such as a game console or desktop computer, can be plugged right into the remaining LAN ports on the Secondary Router.
完成选择开放频道后，单击“保存”将所有更改提交到“辅助路由器”。 保存更改后，从用于配置的辅助计算机上拔出辅助路由器，然后将其插入要插入的以太网插Kong。 将以太网电缆从墙壁插Kong连接到辅助路由器上的LAN端口之一(而不是WAN端口)。 插入电源线以启动它。 现在，您的辅助访问点应该在线并且可以被附近的Wi-Fi设备访问。 另外，您还可以将辅助路由器用作基本网络交换机，可以将附近的任何与以太网相关的设备(例如游戏机或台式计算机)直接插入辅助路由器上的其余LAN端口。
You can repeat this entire process with additional routers—just pay attention to the channel you select for each router to try and keep the interference to a minimum.
您可以使用其他路由器重复整个过程，只需注意为每个路由器选择的信道，以尽量减少干扰。
