TP-Link Deco M9 Plus 提供的包装和开箱体验都令人愉悦。在包装内，您可以找到入门所需的一切。^{(Both the packaging and the unboxing experience offered by TP-Link Deco M9 Plus are pleasant. Inside the packaging, you find everything you need to get started.)}

硬件规格和设计

TP-Link Deco M9 Plus是一个三频网状WiFi 系统^{(WiFi system)}，总的理论最大带宽划分如下：每个 5 GHz 无线频率为 867 ^{(GHz wireless)}Mbps（总共有两个），2.4 GHz为 400 ^{(GHz frequency)}Mbps频率。根据TP-Link^{(TP-Link one)}，两个 5 GHz频段之一用作WiFi 回程^{(WiFi backhaul)}，仅用于通过Deco M9 Plus站传输数据，以提高无线速度和覆盖范围^{(wireless speed and coverage)}。这种回程也是动态的，从某种意义上说，它可以使用剩余的两个无线频率的一部分，如果数据传输负载^{(data transfer load)}高。TP-Link Deco M9 Plus支持 802.11ac Wave 2无线标准 (Wi-Fi 5)、2x2 MU-MIMO 传输以及较旧的WiFi标准，如 802.11b/g/n。

每个TP-Link Deco M9 Plus 站^{(TP-Link Deco M9 Plus station)}都有一个四核Qualcomm IPQ4019 处理器^{(Qualcomm IPQ4019 processor)}，运行频率为 717 MHz，512 MB RAM和 4 GB用于固件的闪存存储空间。^{(storage space)}在每个Deco M9 Plus内部，有六个无线天线，一个用于蓝牙 4.2^{(Bluetooth 4.2)}，一个用于ZigBee HA1.2 - 一些智能物^(Things)联网^(IoT)（物联网^(Internet)）设备用于通信和传输数据的协议。说到智能设备， TP-Link Deco M9 Plus^{(TP-Link Deco M9 Plus)}的一项独特功能是它能够与智能灯泡等智能家居设备配合使用^{(smart bulbs)}、智能插头、传感器、门锁和恒温器。当您将此类设备连接到网络时，Deco M9 Plus允许您从Deco 应用^{(Deco app)}程序控制智能家居设备，无需额外的集线器。您可以在此处查看兼容设备列表：Deco M9 Plus 智能家居设备兼容列表^{(Deco M9 Plus Smart Home Device Compatible List)}。

在每个TP-Link Deco M9 Plus上，有两个1 Gbps的^(Gbps)以太网^(Ethernet)端口、电源插孔^{(Power jack)}和一个USB 2.0端口，遗憾的是，在^{(USB 2.0)}TP-Link通过固件更新解锁端口之前无法使用。

在每个Deco M9 Plus的底部，有一个重置^(Reset)插孔，用于将其放置在平面上的四个脚，以及通风网格。不幸的是，没有用于墙壁安装^{(wall mounting)}的孔。

TP-Link Deco M9 Plus看起来低调而优雅^{(discreet and elegant)}。您可以将电台放置在现代化的客厅^{(living room)}中，而不会让它变得丑陋。此外，它们的大小使您可以在需要时轻松将它们隐藏起来。每个Deco M9 Plus的直径为 5.6 英寸或 144 毫米，高度为 1.81 英寸或 46 毫米。

如果您想阅读该产品的所有官方规格，请访问此页面：TP-Link Deco M9 Plus 规格^{(TP-Link Deco M9 Plus Specifications)}。

设置和使用TP-Link Deco M9 Plus

使用适用于Android^(Android)和iOS的^(iOS)TP-Link Deco移动应用程序完成Deco M9 Plus网状系统的设置。您还需要一个TP-Link Cloud 帐户^{(Cloud account)}，您可以从应用程序或计算机上创建该帐户。一个缺点是缺乏双重身份验证^{(two-factor authentication)}，以提高您帐户的安全性。我们希望TP-Link将来会添加此安全功能^{(security feature)}。使用您的TP-Link Cloud^{(TP-Link Cloud)}帐户登录后，您可以开始设置过程^{(setup process)}。Deco 设置^{(Deco setup)}向导易于使用，它从选择您拥有的模型开始。

然后，您将完成必要的配置步骤，并要求您设置以下元素：您正在设置的Deco M9 Plus的位置、您的^{(Deco M9 Plus)}互联网连接的详细信息以及^{(internet connection)}无线网络^{(wireless network)}的名称和密码。它将被广播。设置第一台Deco M9 Plus后，您可以添加其余设备。您所要做的就是选择它们的放置位置。该应用程序可帮助他们复制您为第一个Deco^(Deco)所做的设置。要记住的一件事是，发现Deco M9 Plus电台是使用蓝牙^(Bluetooth)进行的。因此，您需要保持蓝牙^(Bluetooth)在您的智能手机或平板电脑^{(smartphone or tablet)}上打开。否则，设置过程^{(setup process)}将不起作用。

当您完成TP-Link Deco M9 Plus 网状系统^{(mesh system)}设置后，该应用程序会自动检查固件更新，如果找到，它会要求您下载并安装最新版本。您应该执行更新，因为较新版本的固件可以提高性能、修复稳定性问题和安全漏洞。固件更新需要几分钟时间，并且需要重新启动所有Deco M9 Plus站。

然后，您可以使用TP-Link Deco移动应用程序查看和配置^{(view and configure)}所有设置。在应用程序的主屏幕上，您会看到连接到网络的设备列表。您还有几个快捷方式和菜单。使用该应用程序，您可以设置大部分基本内容，例如 WiFi 的名称和^(WiFi)密码^{(name and password)}、测试互联网速度^{(internet speed)}、设置设备黑名单、更新固件、启用或禁用WPS，以及设置一些高级功能。

可用的高级设置不多，一切都可以轻松设置。您可以设置端口转发^{(port forwarding)}、启用IPv6 支持^{(IPv6 support)}、DDNS、LED 控制^{(LED control)}和您收到的通知等功能。可以从家庭护理部分配置与^(Homecare)TP-Link Deco M9 Plus捆绑的安全工具。有关它们的更多详细信息，请参阅本评论的第二页。

所有设置都得到了很好的解释，因此您在设置TP-Link Deco M9 Plus时应该没有问题。每个月初，TP-Link Deco移动应用程序都会提供一份报告。它包括有用的统计数据，例如您网络中在线时间最长的设备、您网络中实现的最高互联网速度^{(internet speed)}、连接到网络的新设备数量、阻止的恶意攻击以及您孩子的互联网历史记录（如果家长控制^{(Parental Controls)}已设置。

高级用户不会欣赏的一个缺点是TP-Link不提供对 Web管理用户界面^{(administration user interface)}的访问，就像其他品牌的网状系统一样。这意味着您无法使用移动应用程序提供的基本设置。

我们将大约 20 台设备连接到网络：台式电脑、笔记本电脑、平板电脑、几部智能手机、两个智能插头、一个智能灯泡^{(smart bulb)}、一台Xbox One控制台和一台无线打印机。他们都连接到网络没有问题。我们还能够通过网络共享内容^{(share content)}。

通过网络传输数据时，我们研究了网络传输的可变性。在大多数情况下，在5 GHz 无线^{(GHz wireless)}频段上，传输快速且稳定。在几个房间里有一些变化，但在我们的舒适区^{(comfort zone)}之外没有任何变化。

但是，在 2.4 GHz 无线频段上，当^{(GHz wireless)}Deco M9 Plus必须处理墙壁和门时，可变性会增加很多。看看下面的无线网络传输，它是在与^{(wireless network transfer)}Deco M9 Plus^{(Deco M9 Plus station)}主站被两堵墙隔开的房间里制作的。如您所见，有一些速度下降值得研究和改进。无论如何，这种变化并不明显，但在 2.4 GHz 频段^{(GHz band)}上仍然很明显，未来的固件更新^{(future firmware update)}可能会改善这方面的用户体验^{(user experience)}。

我们对 TP-Link Deco M9 Plus 及其提供的功能感到满意。我们喜欢它的设置简单、运行良好、外观如何以及它提供的功能。有一些问题可能会引起一些人的注意，例如您还不能使用 Deco M9 Plus 上的 USB 端口，并且您需要在使用三年后为防病毒服务付费。此外，目前尚不清楚这项服务在到期后将花费多少^{(We are pleased with TP-Link Deco M9 Plus and what it has to offer. We enjoyed how easy it was to set up, how well it worked, how it looks and the features that it offers. There are a few issues that may raise some eyebrows, like the fact that you cannot yet use the USB port on the Deco M9 Plus, and that you need to pay for the antivirus service after three years of use. Also, it is not clear how much this service is going to cost after its expiration dat)}。

Unboxing the TP-Link Deco M9 Plus mesh WiFi system

The packaging used for Deco M9 Plus is beautiful. It uses calming white and cyan colors. On the top cover you see a picture with the devices that make up the system you just bought, and a list of its essential characteristics.

TP-Link Deco M9 Plus is sold in three variants: with three stations, two stations or just one. We received for testing the variant with three stations. The unboxing is pleasant and worthy of a premium product. Everything is packaged nicely so that it looks good and it is also easy to unbox. In the packaging you find the Deco M9 Plus stations, their power adapters, one Ethernet cable, the Quick Installation Guide, licensing and warranty information.

Both the packaging and the unboxing experience offered by TP-Link Deco M9 Plus are pleasant. Inside the packaging, you find everything you need to get started.

Hardware specifications and design

TP-Link Deco M9 Plus is a three-band mesh WiFi system, with a total theoretical maximum bandwidth split as follows: 867 Mbps for each 5 GHz wireless frequency (there are two of them in total), and 400 Mbps for the 2.4 GHz frequency. According to TP-Link one of the two 5 GHz bands is used as a WiFi backhaul, is reserved for transferring data only through the Deco M9 Plus stations, for improved wireless speed and coverage. This backhaul is also dynamic, in the sense that it can use a portion of the two remaining wireless frequencies if the data transfer load is high. TP-Link Deco M9 Plus offers support for the 802.11ac Wave 2 wireless standard (Wi-Fi 5), 2x2 MU-MIMO transfers, as well as older WiFi standards like 802.11b/g/n.

Each TP-Link Deco M9 Plus station has a quad-core Qualcomm IPQ4019 processor, running at 717 MHz, 512 MB of RAM, and 4 GB of flash storage space for the firmware. Inside each Deco M9 Plus, there are six wireless antennas, one for Bluetooth 4.2, and one for ZigBee HA1.2 - a protocol that is used by some smart IoT (Internet of Things) devices to communicate and transmit data. Speaking of smart devices, one unique feature of TP-Link Deco M9 Plus is its ability to work with smart-home devices like smart bulbs, smart plugs, sensors, door locks, and thermostats. When you connect such devices to the network, Deco M9 Plus allows you to control smart home devices from the Deco app, with no additional hub required. You can see the list of compatible devices, here: Deco M9 Plus Smart Home Device Compatible List.

On each TP-Link Deco M9 Plus, there are two Ethernet ports at 1 Gbps, the Power jack, and a USB 2.0 port which, unfortunately, cannot be used until TP-Link unlocks the port through firmware updates.

On the bottom of each Deco M9 Plus, there is a Reset jack, four feet for placing it on flat surfaces, and the ventilation grids. Unfortunately, there are no holes for wall mounting.

TP-Link Deco M9 Plus looks discreet and elegant. You can place your stations in a modern living room without making it ugly. Also, their size makes it easy to hide them out of sight, when you need to. Each Deco M9 Plus has a diameter of 5.6 inches or 144 mm, and a height of 1.81 inches or 46 mm.

Setting up and using the TP-Link Deco M9 Plus

The setup of the Deco M9 Plus mesh system is done using the TP-Link Deco mobile app for Android and iOS. You also need a TP-Link Cloud account, which you can create from the app or on your computer. One downside is the lack of two-factor authentication, to increase the security of your account. We hope that TP-Link is going to add this security feature in the future. After you log in with your TP-Link Cloud account, you can start the setup process. The Deco setup wizard is easy to use, and it starts with choosing the model that you own.

You then go through the necessary configuration steps, and you are asked to set the following elements: the location of the Deco M9 Plus that you are setting up, the details of your internet connection, and the name and the password for the wireless network that it is going to be broadcast. Once the first Deco M9 Plus is set up, you can add the remaining devices. All you have to do is choose where they are placed. The app helps them copy the settings you have made for the first Deco. One thing to keep in mind is that the discovery of Deco M9 Plus stations is made using Bluetooth. Therefore, you need to keep Bluetooth turned on on your smartphone or tablet. Otherwise, the setup process does not work.

When you are done setting up the TP-Link Deco M9 Plus mesh system, the app automatically checks for firmware updates and, if any are found, it asks you to download and install the latest version. You should perform the update, as newer versions of firmware improve performance, fix stability problems and security vulnerabilities. The firmware updates take a few minutes and involve a restart of all the Deco M9 Plus stations.

Then, you can use the TP-Link Deco mobile app to view and configure all settings. On the main screen of the app, you see the list of devices that are connected to the network. You also have a couple of shortcuts and menus. With the app, you can set mostly basic stuff, like the name and password for the WiFi, test the internet speed, set up a blacklist of devices, update the firmware, enable or disable the WPS, and set a few advanced features.

There are not many advanced settings available, and everything can be set up with ease. You can set features like port forwarding, enabling the IPv6 support, DDNS, the LED control, and the notifications you receive. The security tools that are bundled with TP-Link Deco M9 Plus can be configured from the Homecare section. More details about them can be found on the second page of this review.

All the settings are nicely explained so you should have no issues in setting up the TP-Link Deco M9 Plus. At the beginning of each month, the TP-Link Deco mobile app offers a report. It includes useful statistics like the devices from your network with the most time spent online, the top internet speed achieved in your network, the number of new devices connected to the network, the malicious attacks blocked, and the internet history of your child if the Parental Controls are set up.

One downside that is not going to be appreciated by advanced users is the fact that TP-Link does not offer access to a web administration user interface, as is the case with mesh systems from other brands. This means that you are stuck with the basic settings offered by the mobile app.

We connected about twenty devices to the network: desktop PCs, laptops, tablets, several smartphones, two smart plugs, one smart bulb, an Xbox One console, and a wireless printer. All of them connected to the network without problems. We were also able to share content through the network.

When transferring data through the network, we looked at the variability of network transfers. On the 5 GHz wireless band, transfers were fast and stable, in most cases. There was some variability, in a few rooms, but nothing outside of our comfort zone.

However, on the 2.4 GHz wireless band, the variability can increase by quite a lot, when the Deco M9 Plus has to deal with walls and doors. Look at the wireless network transfer below, made in a room separated by two walls from the main Deco M9 Plus station. As you can see, there are a few speed drops that are worth investigating and improving. The variability is not dramatic by any means, but it is still noticeable on the 2.4 GHz band, and a future firmware update could improve the user experience in this regard.

We are pleased with TP-Link Deco M9 Plus and what it has to offer. We enjoyed how easy it was to set up, how well it worked, how it looks and the features that it offers. There are a few issues that may raise some eyebrows, like the fact that you cannot yet use the USB port on the Deco M9 Plus, and that you need to pay for the antivirus service after three years of use. Also, it is not clear how much this service is going to cost after its expiration date.
