如果您在访问TP-Link WiFi路由器控制面板时看到(Router Control Panel)错误代码 90403(Error code 90403)、错误未知(Error Unknown )消息，那么这篇文章将对您有所帮助。首次设置或更改已配置的路由器时，您可能会在控制面板(Control Panel)中遇到此问题。
整个错误消息说的是这样的 -
Error
Error code: 90403
Error Unknown!
它还显示了一个通常什么都不做的刷新按钮。(Refresh)但是，首先单击此按钮并查看始终是明智的，以防出现轻微的内部问题。
为什么会出现
此问题的根本原因是在设置路由器时无法从路由器源连接互联网。假设您是第一次设置路由器。为此，您将计算机连接到该网络，登录控制面板(Control Panel)，然后输入基本详细信息。在做所有这些事情时，您必须保持与路由器的连接。仅当您在输入详细信息时与路由器断开连接时才会发生此错误。
突然断开与路由器的连接可能有多种原因。
- 路由器不再响应。
- WiFi 驱动程序出现问题。
- 网络适配器有一些冲突。
本文将帮助您找出此问题的根源并加以解决。
(Error)TP-Link WiFi 路由器控制面板中的(TP-Link WiFi Router Control Panel)错误代码 90403
要修复TP-Link WiFi 路由器控制面板(TP-Link WiFi Router Control Panel)中的错误代码 90403 ，请按照以下步骤操作 -
- 检查源互联网连接
- 使用不同的计算机
- 连接到 2.4GHz 网络
- 验证 WiFi 加密狗
- 安装 WiFi 驱动程序
- 运行网络疑难解答
让我们查看这些解决方案的详细版本以了解更多信息。
1]检查源互联网连接
如前所述，您必须检查WiFi路由器的响应能力。无论您的路由器是新的还是旧的，设备中都可能存在制造缺陷，这可能会导致所有问题。
几乎所有的WiFi路由器都有一个“互联网” LED灯，如果它们有互联网来源来广播您的WiFi连接，它就会保持亮起。检查那个LED灯是否打开。或者，重新启动路由器，以便解决常见问题。
2]使用不同的计算机
如果第一个解决方案对您不利，那么是时候检查您的计算机了。最好使用另一台计算机，以便一次解决常见问题。有时，由于某些内部问题，计算机的WiFi组件会停止工作。(WiFi)这就是为什么您可能希望选择其他设备以确保问题源自您的计算机。
3]连接到2.4GHz网络
如果您的路由器同时兼容5GHz 和 2.4GHz 频段(5GHz as well as 2.4GHz bands)，并且您连接到 5GHz 网络，则最好选择 2.4GHz。2.4 GHz和5 GHz数字指的是您的 Wi-Fi 可用于其信号的两个不同“频段(Wi-Fi)”
在一般情况下，这没有任何区别，因为两个网络同时工作。但是，如果您的设备无法通过 5GHz 网络进行更改，请切换到 2.4GHz。
额外提示：(Bonus tip:)如果您收到超过 2.4GHz 的错误消息，请不要犹豫从 2.4GHz 切换到 5GHz。
4]验证WiFi加密狗
如果您使用 Windows 10 笔记本电脑或以太网连接来设置路由器，则此解决方案不适合您。但是，如果您使用第三方WiFi加密狗将您的 PC 连接到WiFi网络，最好验证加密狗是否正常工作。
如果您的WiFi加密狗附带驱动程序 CD，请卸载现有驱动程序，然后重新安装。即使您没有驱动程序 CD，也请查看制造商网站，您可以从该网站下载驱动程序并将其安装到您的系统中。
之后，尝试以下操作 -
- (Insert)将WiFi加密狗插入不同的USB端口(USB)。与其将其插入CPU机箱的端口，不如使用背面的USB端口。
- (Insert)将WiFi加密狗(WiFi)插入另一台 PC 以检查它是否正常工作。
5]安装WiFi驱动程序
如果您使用的是笔记本电脑，这是处理WiFi(WiFi)连接的内置功能，请验证WiFi驱动程序。无论您使用的是Windows 10、8(Windows 10)还是 7，每个操作系统都需要驱动程序才能顺利运行。因此，请确保您已安装最新的 WiFi 驱动程序(installed the latest WiFi driver)。
6]运行网络疑难解答
Windows 10 带有内置的疑难解答程序。运行以下两个网络故障排除程序，看看它是否有帮助 -
尽管Internet 连接(Internet Connections)疑难解答可能不会显示积极的结果，但可以从网络适配器(Network Adapter)疑难解答中获得一些信息。
要运行它们，请按Win+I打开 Windows 设置(open Windows Settings)，然后转到Update & Security > Troubleshoot。现在在您的右侧找到这些疑难解答程序，并一个接一个地运行它们。您还可以阅读在 Windows 10 上运行疑难解答的指南。
我希望这些解决方案对您有用。
Fix Error code 90403 in TP-Link WiFi Router Control Panel
If you see Error code 90403, Error Unknown message while accessing the TP-Link WiFi Router Control Panel, then this post will help you. You may face this issue in the Control Panel while setting up for the very first time or while making a change in an already configured router.
The whole error message says something like this-
Error
Error code: 90403
Error Unknown!
It also shows a Refresh button that does usually nothing. However, it is always wise to click on this button first and see, in case there is a minor internal issue.
Why does it appear
The root cause of this problem is the unavailability of the internet connection from the source of the router while setting it up. Let’s assume that you are setting up the router for the very first time. For that, you connect your computer to that network, log in to the Control Panel, and enter essential details. While doing all these things, you must keep the connection ON with your router. This error occurs only when you get disconnected from the router while entering the details.
There might be several reasons why you get disconnected from the router all of a sudden.
- The router is not responsive anymore.
- WiFi drivers are making issues.
- The network adapter has some conflict.
This article will help you to find out the source of this problem and solve it.
Error code 90403 in TP-Link WiFi Router Control Panel
To fix error code 90403 in TP-Link WiFi Router Control Panel, follow these steps-
- Check source internet connection
- Use a different computer
- Connect to 2.4GHz network
- Verify WiFi dongle
- Install WiFi driver
- Run Network Troubleshooters
Let’s check out the detailed version of these solutions to know more.
1] Check source internet connection
As mentioned earlier, you must check the responsiveness of the WiFi router. Whether your router is new or old, manufacturing flaws can be there in the device, and that can cause all the whole problem.
Almost all the WiFi routers have an “internet” LED light, which stays ON if they get a source of internet to broadcast your WiFi connection. Check if that LED light is turned ON or not. Alternatively, restart your router, so that common issues get resolved.
2] Use a different computer
If the first solution doesn’t work in your favor, it is time to check your computer. It is best if you use a different computer so that you solve the usual problems at once. At times, the computer’s WiFi component stops working due to some internal issues. That is why you may want to opt for a different device to ensure that the problem is being originated from your computer.
3] Connect to 2.4GHz network
If your router has 5GHz as well as 2.4GHz bands compatibility, and you are connected to the 5GHz network, it is better to opt for 2.4GHz. The 2.4 GHz and 5 GHz numbers refer to two different “bands” that your Wi-Fi can use for its signal
In general cases, it doesn’t make any difference since both networks work simultaneously. However, if your device is unable to make changes over the 5GHz network, switch to 2.4GHz.
Bonus tip: Don’t hesitate to switch from 2.4GHz to 5GHz if you get the error message over 2.4GHz.
4] Verify WiFi dongle
If you are using a Windows 10 laptop or an Ethernet connection to set up the router, this solution is not for you. However, if you are using a third-party WiFi dongle to connect your PC to the WiFi network, it is better to verify if the dongle is working without a problem or not.
If your WiFi dongle comes with a driver CD, uninstall the existing driver, and reinstall it. Even if you do not have a driver CD, check out the manufacturer website from where you can download the driver and install it in your system.
After that, try the following-
- Insert the WiFi dongle to a different USB port. Instead of using inserting it to the CPU case’s port, it is better to make use of a rear side USB port.
- Insert the WiFi dongle to a different PC to check if it is working or not.
5] Install WiFi driver
If you are using a laptop, which is the in-built capability to process a WiFi connection, verify the WiFi driver. Whether you are using Windows 10, 8, or 7, every operating system requires a driver so that it runs everything smoothly. Therefore, make sure that you have installed the latest WiFi driver.
6] Run Network Troubleshooters
Windows 10 comes with in-built troubleshooters. Run the following two Network Troubleshooters and see if it helps-
- Network Adapter
- Internet Connections
Although Internet Connections troubleshooter may not show a positive result, it is possible to get something from the Network Adapter troubleshooter.
To run them, open Windows Settings by press Win+I, and go to Update & Security > Troubleshoot. Now find those troubleshooters on your right-hand side, and run them one after one. You can also read out guide to run troubleshooters on Windows 10.
I hope these solutions work for you.
