Browsing slowing to a crawl, 无法流媒体, wi - fi信号下降, wireless dead zones—every one of these problems is maddening in a world where getting online has become, 对于一些, 就像呼吸一样必要. (好吧,也许不是 那 至关重要的...但仍然重要.)
如果你觉得你的Wi-Fi变得缓慢，有很多工具你可以使用 test the speed of your internet. There are also a few tricks you can try to troubleshoot your network issues. 然而, if the only way you can get decent reception is by st和ing next to your wireless router, these simple tips can help optimize your network.
1. Check Your Wired Internet Connection
Before you blame the Wi-Fi, make sure the internet coming into your house is performing as it should. 找一根以太网线，把你的电脑直接插入调制解调器——你可能需要一个 USB到以太网适配器 if your laptop doesn’t have an Ethernet port.
运行一个 速度测试 看看你的网速. 如果它的网速与你的网费不匹配，你可能需要打电话给你的ISP或 代替你的调制解调器. If your 速度测试 does match your internet bill, 但它似乎仍然很慢, it may be time to pony up for a 更好的计划. (My gr和mother was convinced her Wi-Fi was faulty, 结果我告诉她，她订阅的网速只有蜗牛一般的3Mbps.)
If the modem seems okay, try running the test again wirelessly, st和ing right next to the router. If you get similarly good speeds next to the router, but not elsewhere in the house, then your Wi-Fi coverage may be to blame. If your internet is still slow st和ing right next to the router, you may have some outdated gear 那 needs an upgrade.
2. Update Your Router Firmware
在你开始调整之前，更新你的路由器是个好主意. 路由器制造商一直在改进软件，以勉强获得更高的速度. How easy—or how hard—it is to upgrade your firmware depends entirely on your device’s manufacturer 和 model.
最新的 路由器 更新过程是否已构建到管理界面中, so it's just a matter of hitting a firmware upgrade button. 其他模型, particularly if they're older, still require you to visit the manufacturer's website, download a firmware file from your router's support page, 和 upload it to the administration interface. 这很乏味，但仍然是一件好事，因为它将是如此简单的修复.
事实上, even if your wireless network isn't ailing, you should make it a point to update your firmware on a regular basis for performance improvements, 更好的特性, 和安全更新. For help with this, we have a guide on accessing your router’s settings.
If you really want to get the most out of your current router, the adventurous should look at a third-party firmware, 像开源 dd - wrt. 这可以提高性能，并让您访问更高级的网络特性, including the ability to install a 虚拟私人网络 (VPN) 在你的路由器上. 它的设置有点复杂，但对于精通技术的用户来说，它可能是值得的.
3. Achieve Optimal Router Placement
Not all homes will distribute Wi-Fi signal equally. The fact is, where you place the router can 巨大的 affect your wireless coverage. 将路由器放置在一个机柜中并使之远离可能是合乎逻辑的, or right by the window where the cable comes in, but 那's not always the case. Rather than relegating it to a far end of your home, the router should be in the center of your house, 如果可能的话, so its signal can reach to each corner with ease.
此外，无线路由器需要远离墙壁和障碍物的开放空间. So while it's tempting to put 那 ugly black box in a closet or behind a bunch of books, you'll get a better signal if it's surrounded by open air (which should prevent the router from overheating, ). Keep it away from heavy-duty appliances or electronics as well, 因为近距离运行会影响Wi-Fi性能. 如果你能消除工作空间和路由器之间的哪怕一堵墙, you can drastically improve performance.
如果你的路由器有外接天线，可以将它们垂直放置以增加覆盖范围. 如果你能, it even helps to elevate the router—mount it high on the wall or on the top shelf to get a better signal. 有很多工具可以帮助您可视化您的网络覆盖. betway体育希望本周的 的热图 或MetaGeek inSSIDer，它会向你展示Wi-Fi网络的弱项和强项. There are plenty of mobile apps, too, such as 美国网件公司的无线网络分析.

Take a look at your network's administrator interface 和 make sure you have it configured for optimum performance. If you have a dual-b和 router, you'll likely get better throughput by switching to the 5GHz b和 instead of using the more common 2.4 ghz乐队.
Not only does 5GHz offer faster speeds, 但你可能会遇到来自其他无线网络和设备的较少干扰, because the 5GHz frequency is not as commonly used. (It doesn't h和le obstructions 和 distances quite as well, 虽然, so it won't necessarily reach as far as a 2.4 ghz信号并.)
大多数现代双频路由器都可以选择使用相同的网络名称, 或名称, 两个乐队. Check your router's administration interface, look for the 5GHz network option, 和 give it the same SSID 和 password as your 2.4 ghz网络. 这样，你的设备就会自动选择最好的信号.
(If your router doesn't offer you the option to use the same SSID, just give it another name—like SmithHouse-5GHz—和 try to connect to 那 one manually whenever possible.)
干扰是一个大问题，特别是对于那些居住在人口稠密地区的人. Signals from other wireless networks can impact speeds, not to mention some cordless phone systems, 微波, 和 other electronic devices.
Ever play with walkie-talkies as a kid? You may remember how the units needed to be on the same "channel" in order for you to hear each other. And if you happened to be on the same channel as your neighbors, you could listen in on someone else's conversation, even if they were using a completely different set. 以同样的方式, all modern 路由器 can switch across different channels when communicating with your devices.
Most 路由器 will choose the channel for you, 但如果相邻的无线网络也使用相同的信道, you'll encounter signal congestion. 一个好的路由器设置为“自动”会尝试选择拥塞最少的信道, but older or cheaper 路由器 may just choose a predefined channel, even if it isn't the best one. 这可能是个问题.
在windows操作系统的电脑上，你可以看到Wi-Fi网络使用的频道. From the comm和 prompt type Netsh wlan显示全部, 和 you'll see a list of all wireless networks 和 the channels being used in your vicinity. 前面提到的网络分析器也可以显示这些信息, often in an easier-to-read graphical format.
在个人电脑办公室, 例如, betway体育的大多数网络和betway体育的邻居都在使用6频道和11频道. 一般来说，对于2.4GHz you want to stick to channels 1, 6, 和 11 since they're the only ones 那 don't overlap with other channels (which can degrade performance). 5GHz generally uses non-overlapping channels, 然而, which should make selecting the right one much easier.
If you find the Auto setting isn't working well for you, sign into your router's administrator interface, head to the basic wireless category, 和 try selecting one manually (ideally, one 那 isn't in use by many networks in your area). 运行一个nother 速度测试 to see if 那 provides a better signal 和 faster speeds over the Automatic setting in your problem areas.
Keep in mind 那 channel congestion can change over time, so if you choose a channel manually, 你可能想要偶尔检查一下，以确保它仍然是最好的.
这个问题完全有可能与干扰或Wi-Fi范围无关. 如果你的网络是开放的, 或者有弱密码, 你的网络中可能会有一两个不速之客. If the neighbor is downloading multiple 4K movies on your Wi-Fi, your video chats will suffer.
这些工具 can help you find a list of devices on your Wi-Fi, which may help you sniff out uninvited neighbors. Your router’s admin interface may also be a traffic analyzer of some sort 那 will tell you which devices are using lots of data—you may even find one of your own kids is sucking up b和width without you realizing it. (如果是的话，下面是如何做的 踢掉).
Most modern 路由器 come with Quality of Service (QoS) tools to limit the amount of b和width 那 apps use, 就像 美国网件公司菜单 以上. 例如, 你可以使用QoS来优先处理视频通话，而不是文件下载, your call with gr和ma won't drop just because someone else is grabbing a big file from Dropbox. (Sure, their file will take longer, but gr和ma is more important.) Some QoS settings even allow you to prioritize different apps at different times of day.
QoS settings can typically be found under advanced settings in the network's administrator interface. Some 路由器 may even make it easier by offering a one-click multimedia or gaming setting, so you know those applications will be prioritized. 如果你想在共享网络的同时播放游戏，那么就有 你可以采取的步骤 让事情变得更好.
If your router uses an internal antenna, adding an external one would be a good idea, as the latter tends to send a stronger signal. Your router may have come with antennas you can add on yourself, but if not (or if you threw them away long ago), many router manufacturers sell antennas separately.
在许多情况下, you can choose between omnidirectional antennas, which send a signal to all directions, 或定向的, which send a signal in one specific direction. Most built-in antennas tend to be omnidirectional, so if you are buying an external one, it should be marked "high-gain" to actually make a difference.
A directional antenna tends to be a better option, since odds are 那 you aren't experiencing weak spots in your network in every direction. Point your external antenna in the direction of your weak spot, 和 it will broadcast the signal accordingly. 查看路由器制造商的必威betwayapp，了解购买路由器的详细信息.
9. Upgrade Your Obsolete Hardware
It's a good idea to get the most out of your existing equipment, but if you’re running old hardware, you can't expect the best performance. We have a tendency to subscribe to the "if it ain't broke, don't fix it" mentality with back-end devices, 尤其是网络设备. 然而, if you bought your router years ago, you might still be using the older, slower 802.11n st和ard (or God forbid, 802.11g).
较老的路由器可能限制在相当低的带宽，甚至可能有更短的范围. Thus, all the tweaking we've outlined 以上 will only get you so far—the maximum throughput for 802.11g是54Mbps，而802.11n的上限为300Mbps. 最新的802.11ac supports 1Gbps, while next-gen 6 wi - fi路由器 can theoretically hit 10Gbps. betway体育列出的 最好的无线路由器 is a good place to start the search for a faster router.

即使你的路由器是新的, you might have some ancient devices 那 are falling back to older, 慢的标准. 如果你在过去几年里买了一台电脑，你很可能有一台802.11ac wireless adapter, or at least 802.11n. 但你的设备越旧，内置现代科技的可能性就越小. (You might be able to buy a USB无线网络适配器 那 makes things a bit better on those old machines, 虽然.)
还记得, a higher-quality router won't just support those faster st和ards—it'll also do all the things we've outlined 以上 better. It'll have better channel selection, perform better b和 steering for 5GHz devices, 和 include better QoS features.
其他的可能有多用户多输入多输出(MU-MIMO), 比如《必威betwayapp》 阿切尔TP-Link AX11000 频段下游戏路由器. MU-MIMO 路由器 can send 和 receive multiple data streams simultaneously to multiple devices without b和width degradation 和 require specialized testing with multiple clients, but the clients need to be MU-MIMO compatible.
如果你最终买了一个新的路由器，安装过程不会太可怕. betway体育有关于如何做的指南 set up 和 configure the device.
10. Reach Further With a Range Extender or Mesh Wi-Fi
Some newer 路由器 may have better range than your old beater, 但是在很多家庭中, you may still not get the range you need. 如果网络必须覆盖的区域大于路由器的传输能力, or if there are lots of corners to go around 和 walls to penetrate, performance will inevitably take a hit. If all of the 以上 tips fail, it's possible 那 your house is just too big for a single router to send a good signal everywhere. 在这种情况下, 你需要另一个设备 延伸你的信号.
范围延伸部分 从你的路由器接收信号，然后把它转播到你的设备，反之亦然. 然而，虽然它们很便宜，但往往没有 网无线网络系统, which replace your existing router entirely. Instead of merely repeating a router’s signal, 多个单元一起工作，智能地将流量路由回调制解调器, 用一个无线网络覆盖你的房子，覆盖到任何你需要的地方.
Our Top-Rated Wi-Fi Mesh Network Systems全部(5项)
当 setting up these mesh points, you should still use the same rules for figuring out placement: one node will be connected to your modem, 其他每个节点都应该离得足够近，可以接收到固体信号, while still far enough to extend coverage to dead zones.
The traditional downside to Wi-Fi mesh systems has been 那 they're generally more expensive than simply adding a range extender to your existing router. 然而，betway体育预计在不久的将来，在亚马逊的推动下，会看到这一变化 埃罗6 和 埃罗Pro 6, which come in around $100 to $200 less than much of their mesh competition while offering Wi-Fi 6 compatibility 和 even a Zigbee smart home device hub built into the main router.
即使是网状系统, 然而, 请注意，您仍然可能在房子的远端招致一些性能损失, especially if your Wi-Fi has to make multiple “hops”—again, placing the main unit in the center of your house is best, 将节点与以太网连接将产生最好的效果. Trust me: if you truly want problem-free Wi-Fi, 值得让电工在每个网单元上安装几根以太网电缆, 因为根据我的经验, 其他任何事情都是一种妥协，可能符合也可能不符合你的标准.
Mesh Wi-Fi Systems aren't cheap, especially if you have a large home, which will require multiple nodes. 然而, if you're in the market for a new router anyway, they’re absolutely worth considering as an alternative. 如果你精通技术, 你可以通过设置一些更便宜但更复杂的程序来节省一些钱 Ubiquiti UniFi Lite 访问点.
