设置和使用TP-LINK RE450 AC1750 Wi-Fi 范围扩展器(TP-LINK RE450 AC1750 Wi-Fi Range Extender)
设置TP-LINK RE450 AC1750 范围(TP-LINK RE450 AC1750 range)扩展器非常简单。您可以使用范围扩展器(range extender)和无线路由器上的(wireless router)WPS 按钮(WPS button)在几秒钟内连接两个设备。或者，您可以使用包装中捆绑的网络电缆将(network cable)范围扩展器(range extender)连接到网络中的计算机。
然后，启动您最喜欢的网络浏览器并导航(web browser and navigate)到 http://tplinkrepeater.net 或范围扩展器(range extender)的IP 地址（如果您使用(IP address)WPS将其连接到网络）。使用“admin/admin”作为用户名和密码(username and password)并开始配置范围扩展器(range extender)。用户界面简单，易于使用，看起来不错。
为了设置范围扩展器(range extender)如何广播其两个无线网络，您必须首先设置您所在的区域。您会注意到用户界面在配置选项方面没有提供太多。您只获得完成工作所需的基础知识，仅此而已。此外，它不提供任何多语言支持。如您在我们的屏幕截图中所见，用户界面仅提供英文版本。(English)
我们非常欣赏的一个方面是帮助文档(help documentation)制作精良且易于访问。在所有设置列表中，您会在右上角看到一个问号。(question mark sign)如果单击它，它将显示当前屏幕上显示的所有设置的说明。初学者和临时用户会喜欢这个功能。
设置好TP-LINK RE450的工作方式后，我们建议您执行以下操作：
- 更改用于连接管理范围扩展器的(range extender)默认用户名和密码(default username and password)，以提高网络的安全性。
- 将固件更新到最新版本，以受益于错误修复和性能改进。在我们的测试中，我们将其更新为1.0.0 (version 1.0.0) Build 20151203版本，与捆绑在此范围扩展器上的初始(range extender)固件版本(firmware version)相比，它引入了一些有用的修复。
设置完成后，您应该将范围扩展器(range extender)移动到您想要放置它的房间，这样您就可以扩展无线网络(wireless network)的覆盖范围。范围扩展器(range extender)前面的大圆圈表示它是否与路由器连接良好或距离路由器太远。当圆圈为蓝色时，表示连接良好，当圆圈变为红色时，您应该考虑将范围扩展器移近(range extender closer)路由器。
如上图所示，TP-LINK RE450 范围(TP-LINK RE450 range)扩展器又大又笨重。它需要相当大的空间，这对某些用户来说可能是个问题。我们欣赏的一个方面是它有一个用于关闭LED(LEDs)的按钮。在初始设置之后，它们可能会变得更令人讨厌而不是有用的功能。
在我们完成TP-LINK RE450 范围(TP-LINK RE450 range)扩展器的设置并升级其固件后，我们开始将几个设备连接到它：智能手机、笔记本电脑、控制台和无线打印机。我们的网络连接没有连接性或稳定性问题(connectivity or stability issues)。我们要提到的最后一件事是TP-LINK宣传存在一个千兆以太网端口(Gigabit Ethernet port)，该端口充当无线适配器(wireless adapter)，以千兆速度(gigabit speed)将有线设备连接到您的网络。虽然此端口以千兆速度(gigabit speed)工作，但这并不意味着您将获得 1 Gbps 的网络(Gbps network)连接。请记住，TP-LINK RE450 系列(TP-LINK RE450 range)扩展器以无线方式接收网络访问，其无线网络连接(wireless network connection)在速度方面远未提供 1 Gbps。因此，您可以使用以太网端口(Ethernet port)进行连接，但其最大速度将是您的范围扩展器(range extender)连接到无线路由器(wireless router)的速度。
设置和使用 TP-LINK RE450 快速而轻松。有几个步骤要完成，但它们并不是很复杂，即使是初学者也不行。管理界面看起来很棒并且易于使用，但在配置选项方面也很轻巧。更高级的用户将需要更多的控制选项。(Setting up and using the TP-LINK RE450 is quick and painless. There are a few steps to go through but they are not very complicated, not even for beginners. The administration interface looks great and it is easy to use but it's also light in terms of configuration options. More advanced users will want more control options.)

Reviewing TP-LINK RE450 AC1750 Wi-Fi Range Extender
The TP-LINK RE450 AC1750 range extender is the tоp-of-the line range extender from TP-LINK. It's a device that seems great : it's big, with an unusual look, promising specifications and a rathеr high рrice tag. We tested it for about a week, in which we analyzed the user experience offered by this range extender and its wіrеless networking performance. Read this review to see whethеr this range extender is a goоd choice when you need to extend the coverage of your wireleѕs network:
Unboxing the TP-LINK RE450 AC1750 Wi-Fi Range Extender
The packaging of the TP-LINK RE450 AC1750 is worthy of a device with a more premium price tag . On the front, you can see a picture of this device, the model name and its theoretical maximum bandwidth.
Inside the package you will find the range extender, an RJ-45 Ethernet cable, the Quick Installation Guide, the warranty and other leaflets.
The packaging used for the TP-LINK RE450 AC1750 range extender looks good and the unboxing experience is quick and painless.
Hardware specifications
Unfortunately there is no information about the processor and the chipset used by the TP-LINK RE450 range extender. What we know is that this dual-band range extender offers support for the following networking standards: IEEE802.11ac, 802.11n, 802.11g and 802.11b. The maximum theoretical bandwidth is of 450 Mbps for the 2.4 GHz wireless network and of 1300Mbps for the 5 GHz wireless network, leading to a total of 1750 Mbps.
The TP-LINK RE450 range extender is quite large and heavy: it has a size of 6.4 x 3.0 x 2.6 inches or 163 x 76.4 x 66.5mm and a weight of 16.63 ounces or 463 grams.
All it's 3 external antennas are adjustable. On the front of the device you will find several LEDs which indicate the status of its operation. On the right side you have a Reset button, a button for turning On/Off the LEDs on the front of the device and the Power button. On the left side you can find the Ethernet port for connecting other devices to the range extender.
You can find all the official specifications of this range extender, here: TP-LINK RE450 AC1750 Specifications.
Setting up and using the TP-LINK RE450 AC1750 Wi-Fi Range Extender
Setting up the TP-LINK RE450 AC1750 range extender is very easy. You can use the WPS button on the range extender and on the wireless router to connect the two devices in just a couple of seconds. Alternatively, you can use the network cable that's bundled in the packaging to connect the range extender to a computer in your network.
Then, launch your favorite web browser and navigate to http://tplinkrepeater.net or the IP address of the range extender (if you connected it to the network using WPS). Use "admin/admin" for the username and password and start configuring the range extender. The user interface is simple, easy to use and it looks good.
In order to set how the range extender broadcasts its two wireless networks, you must first set the region that you are in. You will notice that the user interface doesn't offer much in terms of configuration options. You get only the basics that are required in order to get the job done and that's it. Also, it doesn't offer any multi-lingual support. The user interface is available only in English, as you can see in our screenshots.
One aspect that we appreciate a lot is the fact that the help documentation is well made and easily accessible. In all the lists of settings, you see a question mark sign in the top-right corner. If you click on it, it shows an explanation for all the settings that are shown currently on the screen. Beginners and casual users will appreciate this feature.
After you set up the way TP-LINK RE450 works, we recommend that you do the following:
- Change the default username and password that is used to connect to administer the range extender, to increase the security of your network.
- Update the firmware to the latest version, to benefit from bug fixes and performance improvements. In our testing, we updated it to version 1.0.0 Build 20151203, which introduced some useful fixes when compared to the initial firmware version that was bundled on this range extender.
Once the setup is done, you should move the range extender to the room where you want it placed, so that you can extend the coverage of your wireless network. The big circle on the front of the range extender signals whether it has a good connection with the router or whether it is too far away from it. When the circle is colored in blue, it's connection is good, when it turns red, you should consider moving the range extender closer to the router.
As you can see in the picture above, the TP-LINK RE450 range extender is large and bulky. It needs quite a bit of room and this may be an issue for some users. One aspect that we appreciated is the fact that it has a button for turning off the LEDs. After the initial setup, they might become more of a nuisance than a useful feature.
After we were done setting up the TP-LINK RE450 range extender and upgrading its firmware, we started connecting several devices to it: smartphones, laptops, consoles and wireless printers. We had no connectivity or stability issues with our network connections. One last thing that we would like to mention is the fact that TP-LINK advertises the presence of a Gigabit Ethernet port that acts as a wireless adapter to connect a wired device to your network at gigabit speed. While this port works at gigabit speed, that doesn't mean you will get a 1 Gbps network connection. Remember that the TP-LINK RE450 range extender received access to the network wirelessly and its wireless network connection is far from offering 1 Gbps in terms of speed. Therefore, you can connect using the Ethernet port but its maximum speed will be the speed at which your range extender connects to the wireless router.
Setting up and using the TP-LINK RE450 is quick and painless. There are a few steps to go through but they are not very complicated, not even for beginners. The administration interface looks great and it is easy to use but it's also light in terms of configuration options. More advanced users will want more control options.
