Steam是最大的在线游戏平台，但这并不意味着它是完美的。它是一个和其他任何计算机应用程序一样的计算机应用程序。您一定会遇到意外问题，例如磁盘写入错误(disk write error)或Steam 无法打开(Steam not opening)，这会大大减少您的游戏时间。
在本文中，我们将重点关注似乎在最糟糕的时候出现的“无法连接到Steam网络”错误。(Steam)如果您无法连接到Steam，您将无法与朋友一起玩，您无法登录您最喜欢的MMORPG，您会感到非常沮丧。因此，这里有一些最常见的修复方法可以帮助您重新回到游戏中。
1. 检查您的互联网连接
这似乎很明显，但很容易忽略基本的连接错误(connection errors)。如果您无法访问互联网(Internet)，您将在尝试登录您的Steam帐户时立即收到“无法连接到Steam网络”的错误消息。(Steam)因此，在您尝试本文中的任何其他修复之前，请确保您的计算机可以访问 Internet(Internet access)。也许您需要重新启动路由器，或者您可能没有插上网络电缆。
2. 以管理员身份运行 Steam
这是一个简单的解决方案，值得在做任何其他事情之前尝试。如果它不起作用，至少你不会浪费超过几秒钟。
找到Steam客户端的快捷方式，右键单击它并选择以管理员身份运行(Run as Administrator)选项。如果您没有桌面快捷方式，您可以通过在Windows搜索字段中输入“ Steam ”来定位客户端。(Steam)
3.重启你的电脑
许多奇怪的错误和网络错误可以通过简单的 PC 重启来修复。重新开始将清除可能阻止您连接到Steam的所有冻结的应用程序、进程和驱动程序。
4.使用不同的互联网协议(Internet Protocol)
默认情况下，Steam使用UDP（用户数据报协议(User Datagram Protocol)）。如果此协议变得不稳定，您将无法连接到Steam并弹出网络错误。解决方案是从UDP切换到TCP（传输控制协议(Transmission Control Protocol)）。更改Steam的Internet协议的方法如下：
1. 右键单击 Steam客户端并选择属性(Properties)。
2. 转到快捷方式(Shortcut)选项卡并通过在末尾添加-tcp来编辑目标(Target)文本。
3. 选择确定(OK)按钮确认更改。
现在您可以重新启动Steam，“无法连接到Steam网络”错误应该会得到修复。
5.检查服务器状态
有时，您的连接没有问题。Steam服务器可能由于各种原因而关闭，因此在尝试进行复杂修复之前，请务必查看 Steam 官方统计页面(Steam stats)。
您只需查看Steam用户图表即可轻松发现中断。
6.检查网络适配器
您(Are)的网络适配器工作正常吗？启动您喜欢的浏览器以查看您的 PC 是否正常连接到Internet。如果一切看起来都很好，那么您的网络适配器很可能没有任何问题。尽管如此，您应该按照以下步骤确认一切正常：
1. 右键单击 Windows图标并从列表中选择设备管理器。(Device Manager)
2. 转到网络适配器(Network adapters)并展开菜单以查看整个适配器列表。
3. 双击适配器以自动打开“属性(Properties)”面板。
4. 检查设备状态(Device status)。
如果网络适配器出现问题并且您没有看到“此设备工作正常”消息，您应该尝试释放并更新 IP 地址(release and renew the IP address)。之后(Afterward)，重新启动计算机并启动Steam客户端。
7. 更新您的网络驱动程序
在设备管理器(Device Manager)应用程序中检查网络适配器时，不妨更新网络驱动程序。驱动程序(Drivers)需要是最新的，以确保您的 PC 平稳运行。一个简单的网络驱动程序更新可能会导致令人讨厌的“无法连接到 Steam 网络”错误，从而使您无法玩自己喜欢的游戏。以下是更新驱动程序的方法：
1.再次启动设备管理器。(Device Manager )
2. 转到网络适配器(Network adapters)部分并展开设备列表。
3. 选择要更新的网络适配器，右键单击它，然后从菜单中选择更新驱动程序。(Update driver)
4. 驱动程序更新窗口(Window)将打开并询问您要如何安装驱动程序。选择自动搜索驱动程序(Search for drivers automatically)选项并按照说明进行操作。
8. 更新 Steam
您可以通过更新Steam客户端来解决许多Steam问题。这包括“无法连接到Steam网络”错误。
在大多数情况下，Steam会在您登录后立即自动更新。但是，有时客户端会受到干扰，导致更新被阻止。要手动更新Steam，您只需点击Steam菜单按钮并选择检查 Steam 客户端更新(Check for Steam Client Updates)。
9.重新安装蒸汽
如果到目前为止没有任何效果，那么是时候重新安装Steam了。您可能正在处理一些丢失或损坏的文件，这些文件会阻止客户端正确连接。
请注意，重新安装 Steam 会删除您的游戏文件夹。这可能会导致您丢失保存文件，因此请确保备份您的游戏文件夹。在重新安装 Steam 之前，您可以简单地将游戏文件复制/粘贴到任何您想要的位置。
也就是说，这是重新安装Steam客户端的方法：
1. 右键单击 Windows图标并选择应用程序和功能(Apps and Features)。
2.滚动(Scroll)应用程序列表，直到找到 Steam 并选择它。
3. 选择卸载(Uninstall)按钮。
4.通过点击安装 Steam(Install Steam)按钮从官方页面重新安装 Steam。(Reinstall Steam)按照说明进行操作，一切顺利。
10.检查Windows防火墙
如果到目前为止绝对没有任何效果并且您仍然无法连接到Steam，则Windows防火墙可能会阻止Steam使用的端口之一。
防火墙有时无法区分好流量和坏流量，因此它将Steam视为潜在威胁并阻止其所有流量。您需要执行以下操作才能让Steam通过：
1.在Windows搜索框中输入(Windows)“ windows security”并启动Windows 安全(Windows Security)应用程序。
2. 在左侧面板中，单击防火墙和网络保护(Firewall & network protection)，然后在右侧面板中选择允许应用程序通过防火墙(Allow an app through firewall)选项。
3.滚动(Scroll)应用程序列表，直到找到 Steam 以及与客户端相关的任何其他内容。选中它们旁边的框以允许它们通过防火墙。
4. 选择确定(OK)按钮确认这些更改。
重新启动计算机并启动Steam。哪个(Which)修复对您有用？在下面的评论中让我们知道！
FIX: Can’t Connect to Steam Network Error
Steam is the largest online gaming platform, but that doesn’t mean it’s perfect. It’s a computer application like any other. You’re bound to encounter an unexpected problem like a disk write error or Steam not opening and that can significantly reduce your gaming time.
In this article, we’re going to focus on the “can’t connect to the Steam network” error that seems to pop up at the worst times possible. If you can’t connect to Steam you can’t play with friends, you can’t log into your favorite MMORPG, and you’re going to feel extremely frustrated. So here are the most common fixes to help you get back in the game.
1. Check Your Internet Connection
This might seem obvious, but it’s easy to overlook basic connection errors. If you’ve lost access to the Internet, you’ll get the “can’t connect to Steam network” error as soon as you try to log in to your Steam account. So before you try any of the other fixes in this article, make sure your computer has Internet access. Perhaps you need to reboot your router or maybe you left the network cable unplugged.
2. Run Steam as Administrator
This is a simple solution worth trying before doing anything else. If it doesn’t work, at least you won’t waste more than a few seconds.
Find the Steam client’s shortcut, right-click it and select the Run as Administrator option. If you don’t have a desktop shortcut, you can locate the client by typing “Steam” in the Windows search field.
3. Restart Your Computer
A lot of strange bugs and network errors can be fixed with a simple PC reboot. A fresh start will clear any frozen applications, processes, and drivers that might be preventing you from connecting to Steam.
4. Use a Different Internet Protocol
By default, Steam uses UDP (User Datagram Protocol). If this protocol becomes unstable, you can’t connect to Steam and the network error pops up. The solution is to switch from UDP to TCP (Transmission Control Protocol). Here’s how you can change Steam’s Internet protocol:
1. Right-click the Steam client and select Properties.
2. Go to the Shortcut tab and edit the Target text by adding -tcp at the end.
3. Select the OK button to confirm the change.
Now you can restart Steam and the “can’t connect to Steam network” error should be fixed.
5. Check the Server Status
Sometimes, there’s nothing wrong with your connection. The Steam servers might be down for various reasons, so before trying a complicated fix make sure you check the official Steam stats page.
You can easily spot an outage just by looking at the Steam users graph.
6. Check the Network Adapters
Are your network adapters working correctly? Launch your favorite browser to see if your PC is connecting to the Internet normally. If everything looks fine, chances are there’s nothing wrong with your network adapters. Nonetheless, you should confirm everything is fine by following these steps:
1. Right-click on the Windows icon and select Device Manager from the list.
2. Go to Network adapters and expand the menu to see the whole list of adapters.
3. Double click on an adapter to automatically open the Properties panel.
4. Check the Device status.
If something is wrong with the network adapter and you don’t see the “This device is working properly” message, you should try to release and renew the IP address. Afterward, restart your computer and launch the Steam client.
7. Update Your Network Drivers
While you’re checking your network adapters in the Device Manager app, you might as well update your network drivers. Drivers need to be up-to-date to ensure your PC is running smoothly. A simple network driver update might be causing that pesky “can’t connect to steam network” error that keeps you from playing your favorite games. Here’s how to update your drivers:
1. Launch the Device Manager once more.
2. Go to the Network adapters section and expand the list of devices.
3. Select the network adapter you want to update, right-click it, and choose Update driver from the menu.
4. The driver update Window will open and ask you how you want to install the driver. Choose the Search for drivers automatically option and follow the instructions.
8. Update Steam
You can fix many Steam issues by updating the Steam client. This includes the “can’t connect to Steam network” error.
In most cases, Steam updates itself automatically as soon as you log in. However, there are times when something interferes with the client and the update is prevented. To manually update Steam, all you need to do is click on the Steam menu button and select Check for Steam Client Updates.
9. Reinstall Steam
If nothing worked so far, it’s time to reinstall Steam. You might be dealing with some missing or corrupted files that are preventing the client from properly connecting.
Take note that reinstalling steam will delete your game folders. This can cause you to lose save files, so make sure you backup your game folders. You can simply copy/paste the game files anywhere you want before reinstalling Steam.
That said, here’s how to reinstall the Steam client:
1. Right-click on the Windows icon and select Apps and Features.
2. Scroll through the list of apps until you find Steam and select it.
3. Select the Uninstall button.
4. Reinstall Steam from the official page by clicking on the Install Steam button. Follow the instructions and you’ll be good to go.
10. Check the Windows Firewall
If absolutely nothing worked so far and you still can’t connect to Steam, the Windows firewall might be blocking one of the ports that Steam uses.
The firewall sometimes fails to tell the difference between good and bad traffic, so it sees Steam as a potential threat and blocks all its traffic. Here’s what you need to do to let Steam pass through:
1. Type “windows security” in the Windows search box and launch the Windows Security app.
2. In the left panel, click on Firewall & network protection and then select the Allow an app through firewall option in the right panel.
3. Scroll through the list of apps until you find Steam and anything else related to the client. Check the boxes next to them to allow them to pass through the firewall.
4. Select the OK button to confirm these changes.
Restart your computer and launch Steam. Which fix worked for you? Let us know in the comments below!
