推出了许多承诺与最新无线网络标准 - 802.11ac 兼容的无线路由器。虽然这很好，但这并不意味着它们都能在较大的公寓和住宅中提供广泛的覆盖范围和强大的信号。当您没有所需的WiFi 覆盖范围(WiFi coverage)时，最好考虑购买范围扩展器(range extender)。虽然您可能会在市场上找到许多范围扩展器(range extender)，但其中很少能提供与 802.11ac 无线网络标准的兼容性。幸运的是，华硕(Luckily ASUS)推出了 RP-AC52双频 Wireless-AC750 范围(Dual-band Wireless-AC750 range)扩展器，能够扩展以 2.4 GHz 频率运行的旧无线网络(GHz frequency)以及使用 5 GHz 频率(GHz frequency)和 802.11ac 标准的现代网络。从这篇详细的评论中了解它的工作情况以及是否值得购买。
华硕 RP-AC52 范围扩展器(ASUS RP-AC52 Range Extender)拆箱
华硕 RP-AC52 范围(ASUS RP-AC52 range)扩展器的包装与华硕(ASUS)制造的其他类似设备相同。在包装盒上，您将看到该设备以及有关其特性的一些信息。
如果您查看盒子的背面，您会注意到华硕 RP-AC52(ASUS RP-AC52)目前是华硕的顶级范围(ASUS)扩展器(range extender)，也是唯一支持 802.11ac 网络标准的扩展器。今年早些时候，我们回顾了他们最实惠的型号——华硕 RP-N14(ASUS RP-N14)。你可以在这里找到它的评论。
打开盒子后，您将立即看到该设备。
在它下面，您还可以找到几种不同语言的保修和手册。
现在让我们看看这个范围扩展器(range extender)在规格方面必须提供什么。
硬件规格
如果您仔细查看设备的正面，您会发现它具有 2.4 Ghz 无线(Ghz wireless)网络和 5 GHz 网络(GHz network)的可视信号指示灯。这是因为它支持所有现代网络标准，包括仅适用于 5 GHz 频谱的(GHz spectrum)IEEE 802.11ac。此范围扩展器(range extender)提供的最大理论带宽对于 2.4 GHz 无线(GHz wireless)网络为 300 Mbps ，对于 5 GHz 无线(GHz wireless)网络为433 Mbps。显然，该设备有两个天线 - 每个工作频率(operating frequency)一个。
该设备的正面还可以用作触摸面板，用于打开和(On)关闭它(Off)提供的不同功能。但在本次审查的稍后部分会对此进行更多介绍。
在设备的一侧，您会找到一个以太网端口(Ethernet port)，您可以使用该端口将设备连接到路由器，并将其用作接入点或(access point)范围扩展器(range extender)的另一个网络设备(network device)。
在以太网端口(Ethernet port)附近，您会发现一个音频插孔(audio jack)，可用于连接耳机或扬声器，这样您就可以直接从ASUS RP-AC52收听(ASUS RP-AC52)网络广播(Internet radio)。
在另一侧，您会找到用于打开和关闭设备的按钮，以及用于将范围扩展器(range extender)快速连接到路由器的WPS 按钮。(WPS button)

设置和使用ASUS RP-AC52 范围扩展器(ASUS RP-AC52 Range Extender)
下面是我们如何设置测试公寓的图表。(test apartment)这是一个相当大的公寓，如果你没有很好的路由器，无线覆盖(wireless coverage)在远离它的厨房或中等阳台等房间会变得相当弱。(medium balcony)你可以看到我们把路由器放在客厅里(living room)，把增程器(range extender)放在走廊里。我们使用的路由器是ASUS RT-AC56U，我们在这里进行了评测。
设置ASUS RP-AC52 范围(ASUS RP-AC52 range)扩展器的最快方法是使用WPS。确保(Make)在您的路由器上打开此功能，然后按下范围扩展器(range extender)上的WPS 按钮(WPS button)。几秒钟后，它会自动设置自己。如果您不知道WPS是什么，我们建议您阅读这篇文章：简单问题：什么是WPS（Wi-Fi Protected Setup）？。
打开网络浏览器并访问http://repeater.asus.com或分配给中继器的IP 地址。(IP address)
由于要配置的参数很少，而且它提供的默认值很好，因此设置中继器花费的时间很少。但是，请不要犹豫，浏览所有配置菜单(configuration menus)并了解有关此设备所提供功能的更多信息。
我们发现的一个有趣的设置是漫游助手(Roaming assistant)。启用后，中继器将断开无线信号较弱的设备，并允许它们连接到在这些位置应提供更好信号强度的路由器。如果您使用的是ASUS RT-AC56U等华硕路由器(ASUS router)，该路由器将具有相同的功能，并且在中继器和路由器上使用它可以获得更好的体验。例如，当您带着平板电脑在房子里走动时，当它的无线信号较弱时它会断开连接，以便它可以连接到在该区域提供最佳无线信号的设备。
在语言支持(language support)方面，华硕 RP-AC52(ASUS RP-AC52)的用户界面只有 11 种语言，比华硕(ASUS)路由器提供的要少。
总而言之，我们对设置过程感到满意。它快速且无痛，它使我们能够在几分钟内使用增程器。(range extender)
在我们对华硕 RP-AC52 范围(ASUS RP-AC52 range)扩展器进行为期 1 周的测试期间，我们使用了可用的最新固件版本 - 1.0.1.0p。
使用此设备时我们没有遇到任何问题。我们能够将我们所有的设备连接到它，从笔记本电脑到我们的Surface Pro 2和我们的智能手机（包括Windows Phone 和 Android(Windows Phone and Android)）。Windows中的网络共享功能运行良好，我们能够与连接到范围扩展器的设备(range extender)共享和传输文件(share and transfer files)和文件夹。使用家庭组(Homegroup)功能也很容易。
Reviewing ASUS RP-AC52 - A Range Extender for 802.11ac WiFi Networks
Manу wireless routers were launched whiсh promisеd compatibilіty with the latest wireless networking standard - 802.11ac. While this is good, it doesn't mean that all of them offer a wide coverage and a strong signаl in larger apartments and homes. Whеn yoυ don't haνe the WiFi covеrage you wаnt, it is a good idea to consider buying a range extender. Whilе you may find many range extenders on the market, verу few of them offer compatіbility with the 802.11ac wireless networking standard. Luckily ASUS has launched the RP-AC52 Dual-band Wireless-AC750 range extender which is capable of extending both older wirelesѕ networks running at the 2.4 GHz frequency as well as modern networks using the 5 GHz frequency and the 802.11ac standard. Learn how well it works and whether it is worth buying, from this detailеd review.
Unboxing the ASUS RP-AC52 Range Extender
The packaging for the ASUS RP-AC52 range extender is the same as for other similar devices made by ASUS. On the box you will see the device and a bit of information about its characteristics.
If you look on the back side of the box, you will notice that ASUS RP-AC52 is currently the top range extender from ASUS and the only one that offers support for the 802.11ac networking standard. Earlier this year we have reviewed their most affordable model - ASUS RP-N14. You can find its review here.
As soon as you open the box, you will immediately see the device.
Beneath it, you will also find the warranty and the manual in several different languages.
Now let's take a look at what this range extender has to offer in terms of specifications.
Hardware Specifications
If you look carefully on the front of the device, you will see that it has visual signal indicators for both the 2.4 Ghz wireless network and the 5 GHz network. That's because it offers support for all modern networking standards, including IEEE 802.11ac, which works only in the 5 GHz spectrum. The maximum theoretical bandwidth offered by this range extender is 300 Mbps for the 2.4 GHz wireless network and 433Mbps for the 5 GHz wireless network. Obviously, this device has two antennas - one for each operating frequency.
The front side of the device works also as a touch panel for turning On and Off the different features that it offers. But more on that later in this review.
On one side of the device you will find an Ethernet port that you can use to connect the device to the router and use it as an access point or another network device to the range extender.
Near the Ethernet port you will find an audio jack which can be used to connect headphones or speakers, so that you can listen to Internet radio, directly from ASUS RP-AC52.
On the other side you will find the button for turning the device on and off, as well as the WPS button for quickly connecting the range extender to the router.
You can find the full list of hardware specifications here: ASUS RP-AC52 specifications.

Setting Up & Using the ASUS RP-AC52 Range Extender
Below you have a diagram of how our test apartment is set up. It is a reasonably large apartment and, if you don't have very good router, the wireless coverage can get rather weak in rooms like the kitchen or the medium balcony which are far away from it. You can see that we have placed the router in the living room and the range extender in the hallway. The router that we used is ASUS RT-AC56U, which we have reviewed here.
The quickest way for setting up the ASUS RP-AC52 range extender is to use WPS. Make sure that this feature is turned on on your router and then press the WPS button on the range extender. In a couple of seconds it will automatically set itself up. If you don't know what WPS is, we recommend that you read this article: Simple Questions: What is WPS (Wi-Fi Protected Setup)?.
Open a web browser and go to http://repeater.asus.com or to the IP address that was assigned to the repeater.
Setting up the repeater takes little time due to the fact that there are few parameters to configure and the defaults it provides are good. However, don't hesitate to go through all the configuration menus and learn more about what this device has to offer.
One interesting setting that we discovered is the Roaming assistant. When enabled, the repeater will disconnect devices that have weak wireless signal and allow them to connect to the router which should provide better signal strength in those locations. If you are using an ASUS router like the ASUS RT-AC56U, the router will have the same feature available and using it on both the repeater and the router makes for a better experience. For example, as you walk around the house with your tablet, it will get disconnected when it wireless signal is weak so that it can connect to the device offering the best wireless signal in that area.
In terms of language support, ASUS RP-AC52 has its user interface available in only 11 languages, which is fewer than ASUS routers provide.
All-in-all we were pleased by the set up process. It was quick and painless and it allowed us to use the range extender in a matter of minutes.
During our 1 week-long testing of the ASUS RP-AC52 range extender, we have used the latest firmware version that was available - 1.0.1.0p.
We had no issues when using this device. We were able to connect all our devices to it, from laptops to our Surface Pro 2 and our smartphones (both with Windows Phone and Android). The network sharing features in Windows worked well and we were able to share and transfer files and folders with the devices that were connected to the range extender. Using the Homegroup feature was also a breeze.
