设置和使用D-Link DIR-822 AC1200 无线(D-Link DIR-822 AC1200 wireless)路由器
您可以使用计算机和网络浏览器或智能手机和移动应用程序设置D-Link DIR-822 无线路由器。(D-Link DIR-822 wireless)最快的方法是使用当您在网络浏览器(web browser)中键入路由器的IP 地址时打开的(IP address)简易设置(Easy Setup)页面。此页面要求提供Internet 连接(internet connection)详细信息，以及将由路由器广播的两个无线网络中的每一个的名称和密码。
虽然这种方法非常快速和简单，但它不会为路由器设置管理员密码(administrator password)，并且您无法设置WiFi使用的安全类型，从而使您的路由器易于被他人破解和远程控制。
最好的方法是加载标准的Internet 连接设置向导(Internet Connection Setup Wizard)，首先为路由器设置密码，然后配置您的 Internet 连接。完成后，加载管理用户界面(administration user interface)，配置您的无线网络(wireless network)，更改路由器的工作方式，并将固件更新到最新版本。
另一种简单的方法是使用适用于iOS和Android的(Android)QRS Mobile应用程序。该应用程序允许您选择路由器的操作模式(operating mode)、配置其与互联网的连接、WiFi的名称和密码、设置固件通知并保存您的设置。
完成初始设置后，您应该加载管理界面(administration interface)。不幸的是，它看起来过时了，而且使用起来很麻烦。有太多的数据、太多的行话和太多的手动设置需要执行。如果你不是技术人员，很难不感到不知所措。
即使是像QoS 服务(QoS service)这样标榜为简单和“智能”的功能，如果您是临时用户，配置起来也是一项艰巨的任务。您需要选择队列类型(queue type)，设置ID和每个ID的权重，然后添加分类规则。
由于这种复杂性，如果您想在路由器上更改任何更高级的内容，您必须查阅用户文档。(user documentation)虽然文档做得很好，但它不像其他品牌的路由器那样容易导航。
用户界面(user interface)有更多语言版本，但尚不清楚支持哪些语言。D-Link的方法与其他制造商不同，并且不提供更改语言的简单方法。使用的语言因您购买路由器的国家和安装的语言包而异。

Reviewing D-Link DIR-822: The affordable WiFi router!
When you read the produсt page of the D-Link DIR-822 AC1200 wireless router, yоu find terms like "extreme сoverаge," "dual-band with a kick" or "intelligent QoЅ." It is funny and pompous when you cоnsider that these words describе a very cheap router that costѕ a bit less than 50 US dollars. Thе market of AC1200 wireless routers is filled with many affordаble devіces, and many people buy them because of their price, and sometimeѕ, because of their features. We took the D-Link DIR-822 wireless router for tеsting, to see whеther D-Link's description mаtches the real-life performance of this product. To see what we found, read this review:
D-Link DIR-822 AC1200: Who is it good for?
D-Link DIR-822 is a suitable choice for:
- Small-sized apartments and networks with a small number of devices
- People with a very low budget
- Users who do not need a USB port on their router and advanced networking features
NOTE: We received the D-Link DIR-822 AC1200 wireless router for testing, from Gearbest.com. It is an online shop that offers excellent prices and international free shipping. You can buy this router at a discount price, from here.
Pros and cons
D-Link DIR-822 has the following positives:
- It is very affordable
- It can be mounted on walls
- It offers support for the modern 802.11ac standard and 2x2 MU-MIMO transfers
- Its performance is good on the 2.4 GHz band
There are also downsides to consider:

- The WiFi has sudden drops in performance that lower the quality of your networking experience
- WiFi performance on the 5 GHz band is much lower than that of its competitors
- It is incapable of using internet connections which are faster than 100 Mbps
- The Ethernet ports work at a maximum of 100 Mbps
- It is difficult to configure when compared to routers from other brands
- D-Link uses poor security practices in its Easy Setup page
Verdict
D-Link DIR-822 AC1200 is a very affordable dual-band wireless router. Because of that, it does not have powerful hardware or advanced features to brag about. We were pleasantly surprised to see that the WiFi on the 2.4 GHz band is quite fast for an AC1200 wireless router. However, the WiFi signal suffers from sudden performance drops, and the WiFi on the 5 GHz band tends to be a lot slower than that of other wireless routers. Also, the user interface for administering this router is old-school and challenging to use. At a similar price, you get better options from the competition, and we recommend that you choose another wireless router.
Unboxing the D-Link DIR-822 AC1200 wireless router
The D-Link DIR-822 AC1200 wireless router comes in a relatively thin blue box with a picture of the devices on its front. On the sides, you can see printed some of its essential features and basic information about this product.
When you open the package, you find inside the following: the router itself, the power adapter, a short network cable, the quick setup guide, the warranty and information about the licensing terms for the D-Link firmware. We found the cable of the power adapter to be rather short, so you need to keep the router close to a plug.
The unboxing experience is quick and easy, just as you would expect from an affordable device of this type. Inside the package, you get the basics you need to make the router work.
Hardware specifications and design
D-Link DIR-822 has a single core Realtek RTL8197DL processor running at 660 MHz, 64 MB of RAM, and just 8 MB of storage space for the firmware. This processor offers support for the latest 802.11ac wireless standard and 2x2 MU-MIMO transfers.
This router is dual-band, with a maximum theoretical bandwidth of 300Mbps for the 2.4GHz band, and 867Mbps for the 5GHz wireless band. It has four external antennas that cannot be detached, only moved to the position you desire. On the top side, you also have LEDs signaling the status of the internet connection, the two wireless networks that are broadcast and the Ethernet ports on the back of the router.
On the bottom, there are a few mounting holes, so that you can place this router on walls. On the back, there are four LAN ports that work at a maximum speed of 100 Mbps, and the port for connecting the router to the internet. There you have the power connector, the Power button, and the WPS button.
Regarding size, D-Link DIR-822 is rather small, at 7.48 x 5.23 x 1.49 inches or 190 x 133 x 38 mm in length x width x height. It also weighs just 9.2 ounces or 263 grams.

Setting up and using the D-Link DIR-822 AC1200 wireless router
You can set up the D-Link DIR-822 wireless router using a computer and a web browser or your smartphone and a mobile app. The fastest method involves using the Easy Setup page that opens when you type the IP address of the router, in a web browser. This page asks for the internet connection details, as well as the name and the password for each of the two wireless networks that are going to be broadcast by the router.
While this method is incredibly fast and easy, it does not set an administrator password for the router and you cannot set the type of security used for the WiFi, making your router easy to hack and remote control by others.
The best method is to load the standard Internet Connection Setup Wizard, which starts by setting up a password for the router, and then configures your internet connection. Once you are done with that, load the administration user interface, configure your wireless network, change the way the router works, and update the firmware to the latest version.
Another easy method is to use the QRS Mobile app for iOS and Android. The app allows you to select the operating mode for the router, configure its connection to the internet, the name and the password for the WiFi, set up firmware notifications, and save your settings.
Once the initial set up is done, you should load the administration interface. Unfortunately, it looks dated, and it is cumbersome to use. There's too much data, too much jargon, and too many manual settings to perform. If you are not a technical person, it is difficult not to feel overwhelmed.
Even features which are marketed as simple and "intelligent" like the QoS service, are a gargantuan task to configure if you are a casual user. You need to choose the queue type, set ID's and the weight of each ID, and then add classification rules.
Because of this complexity, you have to consult the user documentation, if you want to change anything more advanced on your router. While the documentation is well done, it is not as easy to navigate as it is on routers from other brands.
The user interface is available in more languages, but it is not clear which languages are supported. D-Link has a different approach than other manufacturers and does not offer an easy way to change the language. The language used differs based on the country where you purchased the router and the language packs that are installed.
After configuring the D-Link DIR-822 wireless router, we connected all our devices to it: desktop PCs, laptops, tablets, smartphones, smart plugs, a smart bulb, a wireless printer, and an Xbox One console. We had no issues in connecting our devices, and we were able to perform network transfers with ease. The speed we enjoyed was good for an AC1200 wireless router, especially on the 2.4 GHz frequency. However, we did notice sudden drops in performance that plagued some of our network transfers. You can see below a graphical representation of a WiFi network transfer that we performed in the same room with the router. While the average speed was good, it had sudden drops in the middle of the transfer. We encountered this issue daily, for the whole week we tested the D-Link DIR-822 wireless router.
Configuring the D-Link DIR-822 wireless router is easy. However, the administration user interface is dated and hard to use for a home user with limited technical knowledge. D-Link should make its firmware and apps friendlier to use.
