重要提示：(IMPORTANT:)如果您拥有华硕 Lyra 网状 WiFi 系统(ASUS Lyra mesh WiFi system)，但没有看到本指南中共享的配置选项，则表示您拥有旧固件。要解决此问题，请前往华硕支持，下载并安装适用于您的(ASUS Support)华硕 Lyra(ASUS Lyra)的最新固件。
步骤 1(Step 1)。分析您所在地区的无线频谱(wireless spectrum)，查看哪些信道不那么繁忙
从分析您所在地区的无线网络开始是个好主意。如果您有笔记本电脑或 Macbook(laptop or Macbook)，您可以使用NetSpot 应用程序(NetSpot app)（也提供免费版本）查看哪些频道很忙，哪些频道没有被其他网络使用，或者至少不太忙。
如果您使用的是Android智能手机，您可以使用免费的NetSpot - WiFi Analyzer并查看您所在地区的无线网络(wireless network)。例如，在下面的屏幕截图中，您可以看到在 2.4 GHz 频段(GHz band)上，在我们所在的地区，1 到 7 的频道很忙，被许多WiFi网络使用，而 8 到 13 的频道则不那么拥挤。因此，为我们的无线网络(wireless network)使用 8 到 13 之间的信道是一个好主意，以获得最佳的速度，并且与该地区的其他无线网络(wireless network)的拥塞最少。
步骤 2(Step 2)。访问华硕路由器或华硕 Lyra 网状 WiFi 系统的设置(ASUS router or ASUS Lyra mesh WiFi system)
虽然华硕(ASUS)提供移动应用程序来管理您的路由器或网状(router or mesh) WiFi 系统(WiFi system)，但最详细的配置是通过您的网络浏览器中的(web browser)用户界面(user interface)完成的，网址为 router.asus.com。在笔记本电脑或 PC(laptop or PC)上打开您最喜欢的网络浏览器(web browser)，然后访问router.asus.com。然后，使用您的用户帐户和密码登录(user account and password)。
注意：(NOTE:)如果您在登录华硕路由器(ASUS router)的其他方式方面需要帮助，请阅读：如何登录华硕路由器(ASUS router)：四种工作方式。
步骤 3(Step 3)。为您的华硕路由器或华硕 Lyra 网状 WiFi 系统(ASUS router or ASUS Lyra mesh WiFi system)设置无线模式(wireless mode)
您的大部分改进都是在左侧菜单中的无线类别中进行的。(Wireless)单击无线(Wireless)，然后转到右侧的常规。(General)查找无线模式(Wireless Mode)字段并选择适当的模式。您可以在以下值之间进行选择，具体取决于您配置的频段（2.4 GHz或 5 GHz）：
- 自动(Auto)- 对于大多数ASUS路由器/网状系统，这是最佳选择，因为它往往会为您的(ASUS)WiFi提供最佳速度。
- N Only - 它使用旧的 802.11n ( Wi-Fi 4 )无线标准(wireless standard)。仅适用于 2.4 GHz 频段(GHz band)，并且仅当您拥有无法使用较新无线标准(wireless standard)的旧网络设备时，它才是一个不错的选择。
- Legacy - 它使用更旧的标准，如 802.11 b/g/a，大多数用户不应使用此模式。但是，如果您有 10 年以上的网络设备，它们可能无法连接到您的WiFi，除非您使用此模式。我们强烈建议您仅将Legacy用于 2.4 GHz 频段(GHz band)，而不是 5 GHz 频段(GHz band)。
- N/AC Mixed - 此设置仅适用于 5 GHz 频段(GHz band)，且仅适用于ASUS的(ASUS)双频或三频无线路由器(dual-band or tri-band wireless routers)，不适用于ASUS Lyra网状WiFi系统。此模式使用 802.11n ( Wi-Fi 4 ) 和 802.11ac ( Wi-Fi 5 ) 标准提供无线网络。(wireless network)同样(Again)，仅当您遇到网络设备的兼容性问题时才应使用此模式。
请记住(Remember)为两个频段设置无线模式(wireless mode)：2.4 GHz和 5 GHz。在频段(Band)字段中，从常规(General)选项卡中切换频段，设置无线模式(wireless mode)，然后单击应用(Apply)。
第 4 步(Step 4)。为您的无线网络(wireless network)选择最佳信道带宽(channel bandwidth)
在General选项卡中，选择您要配置的Band ，然后查找(Band)Channel bandwidth字段。单击(Click)它，然后选择要使用的带宽： 20 MHz、 40 MHz、 80 MHz或三者的组合。带宽越宽，您的无线网络(wireless network)使用的通道就越多。如果您所在地区的无线频谱(wireless spectrum)是免费的，最好选择更大的带宽值。例如，在我们所在的地区，5 GHz 频段(GHz band)几乎是完全免费的。只有一个其他 5 GHz 无线网络(wireless network). 因此，在该频段使用 80 MHz 带宽(MHz bandwidth)时，我们获得了最佳速度。
在 2.4 GHz 频段(GHz band)，该地区有许多无线网络。因此，我们在使用较小的 20 MHz 带宽(MHz bandwidth)和空闲的特定信道时获得最佳速度，因为较小的带宽不会与该区域内的其他网络重叠。请记住(Remember)为两个频段（2.4 GHz和 5 GHz ）设置信道带宽(channel bandwidth)，然后单击Apply。
步骤 5(Step 5)。为您的两个无线频段使用(Use)免费频道：2.4 GHz和 5 GHz
在本指南的第 1 步(step 1)，我们要求您分析您所在地区的无线频谱(wireless spectrum)，并查看哪些信道繁忙，哪些信道不繁忙。在General选项卡中，选择要配置的Band ，然后查找(Band)Control Channel字段。然后，选择您所在地区免费的频道，或者至少比其他频道不那么忙。
(Set)为两个频段（2.4 GHz和 5 GHz ）设置信道，然后单击Apply。
步骤 6(Step 6)。为您的无线网络(wireless network)启用多用户 MIMO(Multi-User MIMO)
多用户 MIMO(Multi-User MIMO)允许无线路由器和网状WiFi系统同时为多个网络客户端提供服务，并且应该在可用的 5 GHz 频段(GHz band)启用该技术。因此，在专业(Professional)选项卡中，选择 5 GHz 频段(GHz band)，并确保始终启用多用户 MIMO 。(Multi-User MIMO)
该技术不适用于 2.4 GHz 频段(GHz band)和 802.11n ( Wi-Fi 4 ) 等旧无线标准，仅适用于 802.11ac ( Wi-Fi 5 ) 或 802.11ax ( Wi-Fi 6 ) 等新标准。
步骤 7(Step 7)。为您的无线网络(wireless network)启用显式波束成形(Explicit Beamforming)
在Wireless部分的(Wireless)Professional选项卡中，选择 5 GHz 频段(GHz band)，然后查找Explicit Beamforming或802.11ac Beamforming字段。单击(Click)它，并确保它已启用(Enabled)。
该技术允许华硕路由器或网状系统(ASUS router or mesh system)将无线信号的方向引导或聚焦到网络客户端的位置，以改善无线接收(wireless reception)并减少干扰。波束成形(Beamforming)仅适用于 5 GHz 频段(GHz band)。
步骤 8(Step 8)。禁用DoS 保护(DoS protection)以提高性能
对于您可以进行的最后一项改进，请转到左侧列中的防火墙(Firewall)部分，然后单击或点击常规(General)选项卡。在那里，查找显示“启用 DoS 保护”(Enable DoS protection")的设置并将其设置为No。这意味着您禁用了ASUS 防火墙(ASUS firewall)功能，该功能可防止“拒绝服务器”攻击可能会以大量虚假流量(fake traffic)淹没网络。通过禁用此功能，您可以通过释放华硕路由器(ASUS router)或网状WiFi 系统(WiFi system)的硬件资源来提高WiFi的速度。
不幸的是，DoS 保护(DoS protection)会消耗很多硬件资源，每次我们启用它时，我们都会注意到我们测试过的所有华硕路由器的(ASUS)无线性能都较低。(wireless performance)
您对华硕路由器(ASUS router)或网状WiFi 系统(WiFi system)的无线性能有多满意？
在阅读本教程时，您可能会注意到我们推荐的一些设置已在您的ASUS 无线路由器或 ASUS Lyra(ASUS wireless router or ASUS Lyra)网状WiFi系统上启用。其他设置不是，根据我们的建议更改它们将提高您的WiFi 网络(WiFi network)性能。完成所有步骤，然后让我们知道您对所获得的改进有多满意。
8 steps to improve the WiFi speed on an ASUS router or Lyra mesh system
Do you have an ASUS wireless routеr or an ASUЅ Lyra mesh WiFi system? Do you want to get the maximum posѕible speed fоr your WiFi network? Do you plan on buyіng an AЅUS router and yоu want to seе all the optiоns it offers to improve the speed of the WiFi? Then yoυ are in lυck, as thiѕ guide shares eight steps that you can perform to squeeze the maximum possible performance for your WiFi, when using ASUS routers or mеsh WiFi systems:
IMPORTANT: If you own an ASUS Lyra mesh WiFi system and you do not see the configuration options shared in this guide, it means that you have old firmware for it. To fix this problem, go to ASUS Support, download and install the latest firmware available for your ASUS Lyra.
Step 1. Analyze the wireless spectrum in your area, and see which channels are less busy
It is a good idea to start by analyzing the wireless networks in your area. If you have a laptop or Macbook, you can use the NetSpot app (available also in a free version) to see which channels are busy, and which are not used by other networks or at least less busy.
If you use a smartphone with Android, you can use the free NetSpot - WiFi Analyzer and take a look at the wireless networks in your area. For example, in the screenshot below, you can see that on the 2.4 GHz band, in our area, the channels from 1 to 7 are busy and used by many WiFi networks, while channels 8 to 13, as less crowded. Therefore, it is a good idea to use a channel between 8 and 13 for our wireless network, for the best possible speed, and the least congestion with other wireless networks in the area.
Step 2. Access the settings for your ASUS router or ASUS Lyra mesh WiFi system
While ASUS offers mobile apps for managing your router or mesh WiFi system, the most detailed configuration is done from the user interface available in your web browser at router.asus.com. Open your favorite web browser on a laptop or PC, and go to router.asus.com. Then, sign in with your user account and password.
NOTE: If you need help with other ways to log in to your ASUS router, read: How to login to your ASUS router: Four ways that work.
Step 3. Set the wireless mode for your ASUS router or ASUS Lyra mesh WiFi system
Most of your improvements are made in the Wireless category, in the menu on the left. Click Wireless and then go to General on the right side. Look for the Wireless Mode field and choose the appropriate mode. You can choose between the following values, depending on the band that you configure (2.4 GHz or 5 GHz):
- Auto - for most ASUS routers/mesh systems, this is the best choice, as it tends to provide the best possible speed for your WiFi.
- N Only - it uses the old 802.11n (Wi-Fi 4) wireless standard. It is a good choice only for the 2.4 GHz band, and only when you have old network devices that cannot use newer wireless standards.
- Legacy - it uses even older standards like 802.11 b/g/a, and most users should not use this mode. However, if you have network devices that are older than 10 years, they might not connect to your WiFi, unless you use this mode. We strongly recommend that you use Legacy only for the 2.4 GHz band, and not the 5 GHz band.
- N/AC Mixed - this setting is available only for the 5 GHz band, and only on dual-band or tri-band wireless routers from ASUS, not on ASUS Lyra mesh WiFi systems. This mode provides the wireless network using both the 802.11n (Wi-Fi 4) and 802.11ac (Wi-Fi 5) standard. Again, you should use this mode only when you encounter compatibility problems with your network devices.
Remember to set the wireless mode for both bands: 2.4 GHz and 5 GHz. In the Band field, from the General tab, switch between bands, set the wireless mode, and click Apply.
Step 4. Choose the best channel bandwidth for your wireless network
In the General tab, choose the Band that you want to configure and then look for the Channel bandwidth field. Click on it, and select the bandwidth that you want to use: 20 MHz, 40 MHz, 80 MHz, or a combination between the three. The more extensive the bandwidth, the more channels your wireless network uses. If the wireless spectrum is free in your area, it is better to choose a larger bandwidth value. For example, in our area, the 5 GHz band is almost entirely free. There is only one other 5 GHz wireless network. Therefore, we get the best speed when using the 80 MHz bandwidth for this band.
On the 2.4 GHz band, the area is busy with many wireless networks. Therefore, we get the best speed when using a smaller 20 MHz bandwidth, and a specific channel that is free, because the smaller bandwidth does not overlap with other networks in the area. Remember to set the channel bandwidth for both bands (2.4 GHz and 5 GHz), and click Apply.
Step 5. Use free channels for your two wireless bands: 2.4 GHz and 5 GHz
At step 1 in this guide, we asked you to analyze the wireless spectrum in your area and see which channels are busy and which are not. In the General tab, choose the Band that you want to configure and then look for the Control Channel field. Then, pick a channel that is free in your area, or at least less busy than others.
Set the channel for both bands (2.4 GHz and 5 GHz), and click Apply.
Step 6. Enable Multi-User MIMO for your wireless network
Multi-User MIMO allows wireless routers and mesh WiFi systems to serve multiple network clients simultaneously, and this technology should be enabled for the 5 GHz band where it is available. Therefore, in the Professional tab, choose the 5 GHz band, and make sure that Multi-User MIMO is always enabled.
This technology is not available for the 2.4 GHz band and older wireless standards like 802.11n (Wi-Fi 4), only for new standards like 802.11ac (Wi-Fi 5) or 802.11ax (Wi-Fi 6).
Step 7. Enable Explicit Beamforming for your wireless network
In the Professional tab of the Wireless section, select the 5 GHz band, and look for the Explicit Beamforming or 802.11ac Beamforming field. Click on it, and make sure that it is Enabled.
This technology allows the ASUS router or mesh system to steer or focus the direction of the wireless signal to the location of the network clients, to improve the wireless reception and reduce interference. Beamforming is available only for the 5 GHz band.
Step 8. Disable DoS protection for improved performance
For the last improvement that you can make, go to the Firewall section in the column on the left, and then click or tap the General tab. There, look for a setting that says "Enable DoS protection" and set it to No. This means that you disable the ASUS firewall feature that protects against "denial-of-server" attacks that may flood the network with large amounts of fake traffic. By disabling this feature, you improve the speed of your WiFi by freeing the hardware resources of your ASUS router or mesh WiFi system.
Unfortunately, the DoS protection eats up many hardware resources, and each time we enabled it, we noticed lower wireless performance on all ASUS routers that we have tested.
How happy are you with the wireless performance of your ASUS router or mesh WiFi system?
While going through this tutorial, you may notice that some of the settings we recommend are already enabled on your ASUS wireless router or ASUS Lyra mesh WiFi systems. Other settings are not, and changing them according to our recommendations, is going to improve the performance you get for your WiFi network. Go through all the steps, and then let us know how happy you are with the improvements that you have got.
