修复无法连接到 Internet 问题的一些提示(Some Tips to Fix Can’t Connect to the Internet issue)
以下是一些可用于解决此问题的快速提示：
1.很多时候，用户直接深入研究高级解决方案，实际上却错过了可能导致问题的明显原因。电缆线松动(Loose)或损坏、端口功能失调等也会导致此类故障，因此请先查找基本的东西。在开始使用所有其他故障排除方法和解决方案之前，请检查所有物理电缆和端口并确保这些东西工作正常。
2.你的问题真的有问题吗？有时，一个基本的一次性问题被高估为真正的错误。您正在查看的网站可能存在问题，而不是您的整个计算机或路由器存在问题。因此，您必须先查看多个不同的网站，然后再声明您的 Internet 连接存在问题。
3.Internet(Internet)问题的另一个非常明显的原因是您可能超出了无线(Wireless)信号范围。您可能会遇到未找到 Wi-Fi 网络的(No Wi-Fi network found)问题，因为您可能会遇到未找到 Wi-Fi 网络(No Wi-Fi network found)的问题，因为Wi-Fi网络连接性能会随着设备之间的距离而降低。远处的计算机可能会超出路由器的信号范围，从而给您带来麻烦。
4.路由器故障或损坏也会导致此类问题。如果可能，检查显示器或LED(LEDs)以确保路由器工作正常。
5.IP地址冲突也是这个问题的一个普遍原因。这个小问题可能会给您带来很多麻烦，包括互联网连接问题。如果公共网络上的两台设备具有相同的 IP 地址，那么它们都将面临互联网访问问题。因此，请确保您不是这种情况。
6.计算机防火墙主要控制您的网络流量和互联网可访问性。防火墙问题可能是您的问题的原因。防火墙的恶意更新或同时运行的多个防火墙可能会导致此问题。要排除这种可能性，只需暂时禁用您的防火墙。
7.如果您使用加密的无线网络，那么您的计算机必须有一组正确的安全密钥才能成功连接。确保您的无线网络配置未被更改。
8.您的互联网服务提供商(Internet Service Provider)也有可能因为未付费用、终止有效期、下载或上传非法内容等原因阻止了您。在这种情况下，您将再次面临互联网连接和可访问性的中断。
9.您的互联网问题可能是由您的计算机或操作系统本身的一些错误引起的。例如，您的网络适配器可能会损坏，或者您的网络设置可能会受到病毒攻击的影响。
10.如果您没有任何工作，您必须联系您的ISP以验证他们所造成的任何问题，并获得解决问题的提示。
这些是您可以用来解决Internet问题的方法和技巧。

Some Tips to Fix Can’t Connect to the Internet issue
Here are some quick tips that you can use to solve this problem:
1.Many times users dig straight into advanced solutions and in fact, miss the obvious reasons that might actually be causing the issue. Loose or damaged cable wires, dysfunctional ports, etc. can also cause such trouble, so look for the basic things first. Check all physical cables and ports and ensure those things are working fine before starting with all other troubleshooting methods and solutions.
2.Is your problem really a problem? Sometimes, a basic one-time problem is overestimated to be a real error. It is possible that there’s a problem with the website you are looking at and not with your entire computer or router. So, you must check out multiple different websites before declaring a problem in your internet connection.
3.Another very obvious reasons for Internet problem is that you may be out of the Wireless signal range. You may encounter No Wi-Fi network found issue as You may encounter No Wi-Fi network found issue as Wi-Fi network connection performance decreases with the distance between the devices. A far away computer may lie out of the router’s signal range, causing you the trouble.
4.A faulty or damaged router also causes such issues. Check for display or LEDs if possible to ensure that the router is working fine.
5.IP address conflicts is also a popular reason for this problem. This minor issue may cause you a huge number of troubles including the internet connection problem. If two devices on a common network have the same IP address then both of them will face problems with internet access. So, ensure that this is not the case with you.
6.Computer firewalls have major control over your network traffic and internet accessibility. A problem with the firewall may be the reason for your problem. Malicious updates of firewall or multiple firewalls running together may cause this problem. To rule out this possibility, simply, disable your firewall(s) temporarily.
7.If you are using encrypted wireless networks, then your computer must have a correct set of security keys in order to make a successful connection. Ensure that your wireless network configurations have not been changed.
8.It is also possible that your Internet Service Provider has blocked you because of reasons like unpaid charges, termination of validity, downloading or uploading of illegal content, etc. In this case, again, you will face interruption with internet connectivity and accessibility.
9.Your internet problem might have been caused by some error in your computer or OS itself. For example, your network adapter can get corrupted or your network settings might get affected under a virus attack.
10.If nothing is working for you, you must contact your ISP to verify any issue that is being caused on their side and to get tips to troubleshoot the problem.
These were the methods and tips that you can use to solve your Internet issue.
