尝试连接到 Internet 时是否遇到网关身份验证失败错误？如果是，请阅读本指南，了解如何修复 U-verse 调制解调器网关身份验证失败错误。(Do you encounter a Gateway Authentication Failure error when trying to connect to the internet? If yes, then read this guide on how to fix U-verse Modem Gateway Authentication Failure Error.)
什么是网关认证失败错误？(What is the Gateway Authentication Failure Error?)
使用 U-verse 调制解调器连接Internet时经常会出现此错误。如果路由器的初始设置损坏，也可能发生这种情况。路由器(router)捆绑了几个启动设置以加快其设置配置的过程。但是，它可能会损坏，从而阻止您使用互联网。
网关认证失败错误 U-Verse 的原因是什么？
(What is the cause of the Gateway Authentication Failure Error U-Verse?
)
以下是此错误的一些主要原因：
- 路由器堆积了增加其加载时间的启动设置。
- Sudden/abrupt关闭。
- 以太网(Ethernet)线/电缆未连接到正确的ONT端口。
- 路由器(Router)初始设置损坏。
如何修复 U-Verse 调制解调器网关身份验证失败错误
方法一：检查ONT端口(ONT Port)和线缆(Cable)
如果您在光网络终端(Optical Network Terminal)中没有正确的电缆，即ONT端口，您可能会遇到网关认证问题。
1. 检查以太网(Ethernet)线是否连接到正确的ONT端口。
2. 如果您不确定哪一个是ONT端口，请参阅用户手册。
3. 确保电缆连接牢固。即使连接到正确的ONT端口，松散连接的电线也会产生问题。
设置正确的连接后，尝试连接到网关并验证错误是否已解决。如果没有，请使用下一种方法开始故障排除。
方法 2：重启路由器
如果路由器的 Internet 缓存损坏，则可能会发生网关身份验证失败错误。(Gateway Authentication Failure)因此，我们将通过关闭路由器的电源来清除此方法中的缓存，如下所示：
1. 拔下电源线以完全关闭(turn off)调制解调器。
2.从两端拔下(Remove)以太网电缆并(Ethernet)等待(wait )一两分钟。
3.将电源线连接( Connect)到调制解调器并打开(Turn on)路由器。
返回网关并检查是否有任何更改。

方法三：检查网络连接(Network Connection)
一些用户即使在路由器上执行电源循环后也会遇到 U-verse网关身份验证失败。(Gateway)在这种情况下，请按照以下步骤检查您的互联网连接：
1. 检查连接是否松动或电线是否已断开。
2. 如果要创建直接连接，请移除所有电池单元、电涌保护器和其他设备。
3. 与您的ISP（即Internet 服务提供商(Internet Service Provider)）联系，以排除他们的任何问题。
再次尝试连接到网关并验证问题是否已解决。
方法 4：检查中断(Method 4: Check for an Outage)
有时检查和修复中断可以解决此问题。您可以通过访问专门用于此类操作的网站（在本例中为MyATT ）来检查是否存在中断。
1. 进入MyATT页面( page)。
2.使用凭据登录。(Login)
3. 现在选择立即Fix it Now! 如“我的服务帮助(Help with my service )”部分所示。
4. 网关将自动测试(tested automatically)以检查错误。
5. 要应用推荐的修复程序(recommended fixes)，请按照屏幕上提示的步骤进行操作。
6. 退出网站并重新启动(restart)调制解调器。
验证您是否能够修复 U-verse Gateway Authentication Failure Error。如果问题仍然存在，请尝试按照下一个方法中的说明重置调制解调器设置。
方法 5：重置调制解调器设置
注意：(Note:) 请(Please)记住，重置调制解调器也会重置您的所有设备设置。 调制解调器(Modem)重置可以通过以下方式完成：
选项 1：使用重置按钮(Option 1: Using Reset Button)
通过按下调制解调器背面的重置按钮，您可以重置调制解调器设置：
1. 按住重置按钮(Reset button)至少 30 秒。
2. 当灯开始闪烁时，松开(release)按钮。
3. 确保调制解调器已打开(switched on)。
4. 返回网关(gateway)检查是否纠正错误。
选项 2：使用网络浏览器(Option 2: Using a web browser)
1.在浏览器(web browser)地址栏输入192.168.1.1 或(192.168.1.1 or) 192.168.1.2。
注意：(Note:)如果上面的 IP 不起作用，那么您需要在路由器底部或侧面找到您的路由器的 IP 地址）。(find the IP address of your router)
2. 输入您的凭据并按Enter键登录。(log in.)
注意：不同的路由器有不同的默认登录凭据。
3. 选择Settings >> Reset >> 诊断(Diagnostics)。
4. 选择重置为出厂设置(Reset to factory settings )并等待重置过程完成。
5. 重置完成后，调制解调器会自行重启(restart)。

常见问题 (FAQ)(Frequently Asked Questions (FAQs))
Q1。身份验证错误是什么意思？(Q1. What does an authentication error mean?)
此问题通常表明您的网络密码不正确。您必须仔细检查您输入的Wi-Fi密码是否正确。当您重置路由器或更改其设置时，您的路由器密码会自行重置。在这种情况下，您需要输入新密码。
Q2。PDP 身份验证错误是什么意思？(Q2. What does PDP authentication error mean?)
PDP身份验证问题表明您的设备尚未获得自动连接所需的设置。PDP 身份验证(PDP Authentication)错误可能表示网络信息错误、不匹配或丢失。
Q3。路由器和调制解调器有什么区别？(Q3. What is the difference between a router and a modem?)
调制解调器是一种允许您连接到 Internet 或广域网 (WAN)(wide-area network (WAN))的设备。另一方面，路由器将您的设备连接到LAN或Wi-Fi网络，并使它们能够以无线方式相互通信。
调制解调器充当您的互联网网关，而路由器充当您所有设备的中心位置。

Fix U-Verse Modem Gateway Authentication Failure Error
Do you encounter a Gateway Authentication Failure error when trying to connect to the internet? If yes, then read this guide on how to fix U-verse Modem Gateway Authentication Failure Error.
What is the Gateway Authentication Failure Error?
This error is frequently seen when using a U-verse modem to connect to the Internet. It might also occur if the initial settings of the router get corrupted. The router bundles several startup settings to speed up the process of its settings configuration. It can, however, become corrupted and thus, prevent you from using the internet.
What is the cause of the Gateway Authentication Failure Error U-Verse?
Here are some of the primary causes of this error:
- Router piles up launch settings that increase its loading time.
- Sudden/abrupt shutdown of the router.
- Ethernet wire/cable is not attached to the correct ONT port.
- Router initial settings get corrupted.
How to Fix U-Verse Modem Gateway Authentication Failure Error
Method 1: Check the ONT Port & Cable
If you don’t have the correct cable in the Optical Network Terminal, i.e., ONT port, you may encounter a gateway authentication problem.
1. Check that the Ethernet wire is connected to the correct ONT port.
2. If you’re not sure which one is the ONT port, refer to the user manual.
3. Make sure the cable is firmly attached. A loosely connected wire can create issues even when linked to the right ONT port.
Once the proper connections are set up, attempt to connect to the gateway and verify if the error is resolved. If not, begin troubleshooting with the next method.
Method 2: Power Cycle the Router
The Gateway Authentication Failure error can occur if the router’s internet cache is broken. Therefore, we will clear the cache in this method by powering down the router as follows:
1. Remove the power cable to turn off the modem completely.
2. Remove the Ethernet cable from both ends and wait a minute or two.
3. Connect the cords to the modem and Turn on the router.
Return to the gateway and check for any changes.

Method 3: Check the Network Connection
Some users encounter U-verse Gateway authentication failure even after doing the power cycle on the router. In such cases, check your internet connection by following the below steps:
1. Check to see if the connection is loose or if the cords have been disconnected.
2. Remove any battery units, surge protectors, and other equipment if you want to create a direct connection.
3. Check with your ISP, i.e., Internet Service Provider, to rule out any issues from their end.
Try again to connect to the gateway and verify if the problem is fixed.
Method 4: Check for an Outage
Sometimes checking & fixing for an outage can resolve this issue. You can check for an outage by visiting a website dedicated to these kinds of operations, in this case, MyATT.
1. Go to the MyATT page.
2. Login with the credentials.
3. Now choose to Fix it Now! as displayed under Help with my service section.
4. The gateway will be tested automatically to check for errors.
5. To apply the recommended fixes, follow the steps that are prompted on the screen.
6. Exit the website and restart your modem.
Verify if you’re able to fix U-verse Gateway Authentication Failure Error. If the issue persists, try resetting modem settings as explained in the next method.
Method 5: Reset Modem Settings
Note: Please keep in mind that resetting the modem will also reset all of your device settings. Modem resetting can be done in the following ways:
Option 1: Using Reset Button
By pushing the reset button available on the backside of the modem, you can reset the modem settings:
1. Press and hold the Reset button for at least 30 seconds.
2. When the lights begin to flicker, release the button.
3. Make sure the modem is switched on.
4. Return to the gateway to check for rectification of error.
Option 2: Using a web browser
1. Type 192.168.1.1 or 192.168.1.2 into the address bar of the web browser.
Note: If the above IP doesn’t work, then you need to find the IP address of your router which is available either at the bottom or at the side of the router).
2. Type your credentials and hit Enter key to log in.
Note: Different routers have different default login credentials.
3. Select Settings >> Reset >> Diagnostics.
4. Choose Reset to factory settings and wait for the resetting process to be completed.
5. After the reset is finished, the modem will restart itself.

Frequently Asked Questions (FAQs)
Q1. What does an authentication error mean?
This problem usually indicates that your network password is incorrect. You must double-check that you have entered the correct Wi-Fi password. When you reset your router or change its settings, your router password resets itself. In this case, you will need to enter the new password.
Q2. What does PDP authentication error mean?
A PDP authentication issue indicates that your device has not obtained the necessary settings to connect automatically. A PDP Authentication error might indicate faulty, mismatched, or missing networking information.
Q3. What is the difference between a router and a modem?
A modem is a device that allows you to connect to the internet or a wide-area network (WAN). A router, on the other hand, connects your devices to your LAN or Wi-Fi network and enables them to communicate with one another wirelessly.
A modem serves as your internet gateway, whereas a router serves as a central location for all of your devices.
