例如，安装Chrome 操作系统(Chrome OS)更新需要互联网连接。从Play 商店(Play Store)或通过Linux 开发环境(Linux Development Environment)下载应用程序也是如此。此外，某些应用程序（例如视频会议应用程序(video-conferencing apps)）在没有 Internet 连接的情况下将无法运行。
尽管Chromebook(Chromebooks)支持以太网连接，但Wi-Fi更加流行和方便。它也带来了更多的问题。在本指南中，我们将介绍Chromebook(Chromebook)无法连接到Wi-Fi时要尝试的 8 件事。
1.靠近Wi-Fi路由器
如果您的 Chromebook 离路由器太远，它可能会在检测或加入 Wi-Fi 网络时遇到困难。如果您的设备和路由器超出范围，您也可能会遇到连接断开的情况。
如果您使用的是电池供电的移动或便携式路由器，请将其靠近您的Chromebook，然后再次尝试加入网络。您还可以将您的Chromebook移到更靠近路由器的位置，以最适合您的方式。对于插入式路由器，请将其重新放置到离Chromebook或工作区更近的电源插座上。
重新启用 Chromebook 的Wi-Fi也可以解决此问题。关闭设备的Wi-Fi，重新打开，然后尝试加入网络。
2.重启路由器
有时，您的路由器是许多连接问题的根本原因。幸运的是，您不必做太多事情来解决这些问题。重启路由器可以解决阻止 Chromebook 加入 Wi-Fi 网络的临时问题（例如 IP 地址冲突）。
还值得注意的是，路由器可能因过热而发生故障。当您关闭路由器时，我们建议让其冷却几分钟，然后再重新打开。如果您的路由器经常过热，请考虑将其移至通风良好的位置。
3. 重新加入 Wi-Fi 网络
这需要从Chromebook(Chromebook)的内存中删除 Wi-Fi 网络并从头开始重新连接。如果您的Chromebook突然无法加入之前连接的网络，您应该考虑使用此故障排除技术。
- 转到设置(Settings)>网络(Network)，然后选择Wi-Fi。
- 在 Wi-Fi 设置菜单上，展开已知网络(Known networks)部分。
- 在“所有网络”部分中选择有问题的Wi-Fi网络。(Wi-Fi)
- 点击忘记(Forget)按钮。
- 返回Wi-Fi设置菜单并选择Wi-Fi网络。
- 如果网络受到保护，请输入密码并选择连接(Connect)以继续。
如果这不能解决问题，您的Chromebook可能在网络的黑名单上。跳转到下一部分，了解如何将您的 Chromebook 列入 Wi-Fi 网络白名单(whitelist your Chromebook on a Wi-Fi network)。
4. 将您的 Chromebook 列入白名单
设备(Device)黑名单是每个 Wi-Fi 网络的重要安全层。如果您的Chromebook在网络的黑名单中，您将无法连接到 Wi-Fi 连接。如果您有权访问路由器的管理面板，请前往“WLAN”、“安全”或“设备(Device)管理”部分，然后将您的Chromebook从网络的黑名单中删除。
否则，请联系网络管理员将您的Chromebook列入白名单或取消阻止。
5.检查MAC地址限制(MAC Address Restriction)
MAC 地址过滤(MAC Address Filtering)是另一种网络安全机制，可将未经授权或不需要的设备拒之门外。如果您的Chromebook以外的其他设备可以加入Wi-Fi网络，则您的设备可能存在MAC地址限制。前往路由器的管理面板，检查您的Chromebook是否在MAC地址过滤器列表中。从MAC过滤器中删除Chromebook的Wi-Fi地址，然后再次尝试加入Wi-Fi。
但首先，您需要知道 Chromebook 的MAC地址。如何检查：
- 点击屏幕右下角的时间以打开 Chromebook 的通知区域。
- 点击 Wi-Fi 图标下方的下拉按钮。
- 点击网络标题栏中的信息 🛈 图标(info 🛈 icon)。
- Wi-Fi地址是 Chromebook 的MAC地址(MAC)。
6. 重启你的 Chromebook
如果您的路由器配置一切正常，但您仍然无法与Wi-Fi网络建立连接，则这是下一个最佳故障排除步骤。关闭所有打开的应用程序（这样您就不会丢失未保存的数据）并关闭您的Chromebook。
按住电源按钮并在屏幕上选择关机(Power off)，或打开通知区域并点击电源(Power)图标。
等待(Wait)大约 20-30 秒，让Chrome 操作系统(Chrome OS)完全关闭。之后(Afterward)，重新启动Chromebook并尝试连接到Wi-Fi网络。
7. 更新路由器的固件
固件(Firmware)更新通常会提供功能改进，以提高路由器的连接速度并解决技术问题。如果您的Chromebook和其他设备无法与您的 Wi-Fi 网络建立连接，请访问路由器的管理面板或制造商的网站，并检查您的路由器型号是否有固件更新。
8.重置Wi-Fi路由器
如果您在加入或维护无线连接(maintaining a wireless connection)时遇到问题，硬重置路由器总是一个好主意。但是您应该只在用尽所有其他选项后才考虑硬重置。
寻找路由器上的物理重置按钮，或参阅路由器的说明手册以获取准确的分步说明。本关于重置无线路由器的指南(guide on resetting a wireless router)包含您需要了解的所有内容。
请注意，重置路由器也会将连接的密码和其他配置恢复为出厂默认设置。
寻求帮助
请联系您的互联网服务提供商以确认他们是否存在系统故障。此外，请确认您有一个有效的互联网计划。
您还应该考虑联系Chromebook的制造商或访问附近的服务中心。让他们检查您的Chromebook是否可能损坏其网络/Wi-Fi 适配器。如果仍在保修期内，您的Chromebook很可能会免费维修。(Chromebook)如果您的设备受到不可修复的损坏，您可以更换Chromebook 。
Chromebook Won’t Connect to Wi-Fi? 8 Fixes to Try
Inѕtalling Chrome OS updates, for instance, rеquires an internet connection. So does downloading apps from the Play Store or via the Linux Development Environment. Also, certain applications (video-conferencing apps, for example) won’t work without an internet connection.
Although Chromebooks support ethernet connectivity, Wi-Fi is a lot more popular and convenient. It also comes with more problems. In this guide, we’ll cover 8 things to try if your Chromebook won’t connect to Wi-Fi.
1. Move Closer to the Wi-Fi Router
Your Chromebook might encounter difficulties detecting or joining a Wi-Fi network if it’s too far away from the router. You may also encounter dropping connections if your device and the router are out-of-range.
If you’re using a mobile or portable router that’s battery-powered, bring it closer to your Chromebook and try joining the network again. You could also move your Chromebook closer to the router—whichever works best for you. For a plug-in router, relocate it to a power outlet closer to your Chromebook or workspace.
Re-enabling your Chromebook’s Wi-Fi could also fix the problem. Turn off your device’s Wi-Fi, turn it back on, and try joining the network.
2. Restart the Router
Sometimes, your router is the root cause of many connectivity issues. Luckily, you don’t have to do too much to fix these issues. Power-cycling the router can resolve temporary issues (e.g. IP address conflict) preventing your Chromebook from joining a Wi-Fi network.
It’s also worth noting that a router could malfunction due to overheating. When you shut down your router, we recommend allowing it to cool off for a few minutes before turning it back on. If your router overheats too often, consider relocating it to a properly ventilated location.
3. Rejoin the Wi-Fi Network
This entails deleting the Wi-Fi network from your Chromebook’s memory and reconnecting from scratch. You should consider this troubleshooting technique if your Chromebook suddenly won’t join a previously connected network.
- Go to Settings > Network and select Wi-Fi.
- On the Wi-Fi settings menu, expand the Known networks section.
- Select the problematic Wi-Fi network in the “All networks” section.
- Tap the Forget button.
- Return to the Wi-Fi settings menu and select the Wi-Fi network.
- If the network is protected, enter the password and select Connect to proceed.
If this doesn’t fix the problem, your Chromebook is probably on the blacklist for the network. Jump to the next section to learn how to whitelist your Chromebook on a Wi-Fi network.
4. Whitelist Your Chromebook
Device blacklisting is an important layer of security on every Wi-Fi network. If your Chromebook is on a network’s blacklist, you won’t be able to connect to the Wi-Fi connection. If you have access to the router’s admin panel, head to the “WLAN,” “Security,” or “Device Management” section and remove your Chromebook from the network’s blacklist.
Otherwise, contact the network admin to whitelist or unblock your Chromebook.
5. Check for MAC Address Restriction
MAC Address Filtering is another network security mechanism that shuts out unauthorized or unwanted devices. If other devices but your Chromebook can join a Wi-Fi network, there’s probably a MAC address restriction on your device. Head to the router’s admin panel and check if your Chromebook is on the MAC address filter list. Delete your Chromebook’s Wi-Fi address from the MAC filter and try joining the Wi-Fi again.
But first, you’ll need to know your Chromebook’s MAC address. How how to check:
- Tap the time at the bottom-right corner of the screen to open your Chromebook’s notification area.
- Tap the drop-down button below the Wi-Fi icon.
- Tap the info 🛈 icon in the Network title bar.
- The Wi-Fi address is your Chromebook’s MAC address.
6. Restart Your Chromebook
This is the next best troubleshooting step to take if everything looks fine with your router’s configuration but you still can’t establish a connection with the Wi-Fi network. Close all open applications (so you don’t lose unsaved data) and power off your Chromebook.
Hold the power button and select Power off on the screen, or open the notification area and tap the Power icon.
Wait for about 20-30 seconds for Chrome OS to shut down completely. Afterward, restart your Chromebook and try connecting to the Wi-Fi network.
7. Update Your Router’s Firmware
Firmware updates often ship feature improvements that enhance your router’s connection speed and fix technical issues. If your Chromebook and other devices can’t establish a connection with your Wi-Fi network, visit the router’s admin panel or the manufacturer’s website and check if there’s a firmware update for your router model.
8. Reset the Wi-Fi router
If you’re having issues joining or maintaining a wireless connection, hard resetting the router is always a good idea. But you should only consider a hard reset after exhausting all other options.
Look for a physical reset button on the router, or refer to the router’s instruction manual for accurate step-by-step instructions. This guide on resetting a wireless router has everything you need to know.
Note that resetting your router will also revert the connection’s password and other configuration to factory default.
Reach Out for Help
Contact your internet service provider to confirm if there’s a system glitch on their end. Additionally, confirm that you have an active internet plan.
You should also consider contacting your Chromebook’s manufacturer or visiting a nearby service center. Have them examine your Chromebook for possible damage to its network/Wi-Fi adapter. Your Chromebook will most likely be fixed for free if it’s still under warranty. You could get a replacement Chromebook if your unit is irreparably damaged.
