In this digital world, almost everything we do requires the internet. Its impossible to stay even for ten minutes without checking your social media or even accessing anything on the internet. For availability purposes, we use WIFI routers in our houses so that we can connect efficiently to the internet. If you have been paying close attention, you will realize that every time a friend or a guest comes to your house, you will hear the question, “What’s your WIFI password?” of which you will give it out without a second thought. But that question might turn out to be a deadly risk to everything that is connecting to the internet via the router.
没有访客网络的危险
For instance, it might occur that some of your guests or friends don’t take cybersecurity seriously. And in this case, with access to Wi-Fi, they may download files and accidentally download malware. At times their devices may be already infected with malware. When connected to your WIFI network, a malware can hop through the router and infect all the devices. If your computer is accessible via the network, the malware might even tamper with your files and cause havoc. It’s even worse when you have a party, and by the time you realize your devices are infected, it will be already too late.
要避免这种情况，你只需要一个访客网络。大多数路由器都支持这种模式，因此你不必再为其他套餐付费，也不必为客人专门再找一台路由器。
如何正确设置访客 Wi-Fi
设置访客 Wi-Fi 连接非常简单，只需打开路由器设置并添加访客网络即可。具体步骤如下；
连接路由器后，打开浏览器，在 URL/地址栏中输入路由器的 IP 地址。通常情况下，路由器 IP 地址为 192.168.1.1 或 192.168.0.1 或 192.168.100.1，如需确定，请查看路由器手册。输入 IP 地址后单击 "去"，会出现一个包含管理员用户名和密码字段的对话框。如果您没有更改用户名和密码，请检查路由器上或手册中的凭证。建议更改这些凭据以增强安全性。
登录后，路由器的控制面板/设置页面就会出现，您只需找到访客网络部分并启用即可。
需要考虑的访客网络设置
这些基本设置可确保访客网络和主 WIFI 网络的安全。相关条款可能因路由器而异；
- SSID/网络名称- 这是访客网络名称，将显示在路由器附近任何设备的可用连接列表中。
- 设置 WPA 预共享密钥/或网络密钥- 这是密码的其他（网络）名称。请务必确保您设置了一个强大、安全的密码，您可以把它写下来，以避免每个人都反复问您密码。只要确保它与你在主 WIFI 网络中使用的密码不同即可。
- Authentication – This will tell the router the level of security to be used. The first option is always ‘Open Access,’ and this doesn’t require a password. Avoid this option at all times because not only guest will be able to use your WIFI, but also everyone within your router’s proximity. The other options will require passwords and will also dictate the authentication to be used. They include; WPA2-PSK or WPA2-Personal. in some routers these options will prompt you to select the encryption level, choose AES. Others will implement encryption accordingly.
- 访问时间- 这是访客网络的优点之一。这一设置限制了网络的开启时间。例如，你可以预测客人会逗留多长时间，并相应地将其设置为几个小时。
- 访问内联网/网络资源- 为安全起见，应将其关闭。这意味着任何人都无法访问主网上的资源（已连接的家庭设备）。
Lastly, always use a VPN, some guests might have malicious intents.
