WiFi Security

WiFi signals allow us to connect to the Internet, but many people ignore the security of WiFi signals. Here are 4 key points for network security.

Wi-Fi encryption

1. Use encryption

The best defense method is to enable the encryption function, for example, the device needs to enter a password to connect, and choose a connection method such as WPA2/WPA3/WPA2-PSK AES. If you are still using old Wi-Fi devices, you may want to select WPA2-PSK AES + WPA-PSK TKIP to keep these old devices working.
Remember to never click Open, because an open network makes it easy for unknown people to steal your WiFi, or use your WiFi network for illegal purposes.

Wi-Fi Guest Network

2. Set up "Guest Network"

Most routers will have a "Guest Network" function, set up two separate networks, and then connect the main device to the main network, and other external devices to connect to the guest network. Different device classifications are used to isolate unknown devices from accessing files and devices shared in the network through Wi-Fi signals to achieve the effect of protection.
It is recommended to use a different network name (SSID) and password when setting up the guest network, otherwise it will be confused with the main network.


3. Setup Vlan and use Firewall

The best defense is to enable the encryption function, for example, the device needs to enter the password. If the company has a large number of customers or sensitive data, it is recommended to set up Vlan and install a firewall (Firewall) to manage the company network, separate the Wi-Fi network, and prevent the data from being illegal. steal.

We provide:Network Solutions


4. Use VPN function hides IP

The best defense is to enable encryption. For example, the device needs to enter a password. If your router has VPN function, the security effect will be better, because VPN can hide your IP address.

Wi-Fi related Q & A

Q: Our company does not want visitors to enter the company intranet. Is there a way to separate it?

A: Yes, you can set up a GUEST network for visitors. Visitors are not allowed to enter the company's intranet.

Q: When the company has multiple visitors, too many people go online at the same time, causing the Internet to be slow. Can it be solved?

A: Yes, you can limit the internet speed for visitors to avoid internet traffic.

Q: What can I do if I find a company / visitor while browsing an illegal website?

A: Set to block individual websites. When WEB Filtering is enabled in the WIFI system, some illegal websites will be blocked automatically.

Q: I don’t want any cabling job, and the ground is very large. Is there a way to satisfy me?

A: Yes, there are some Wireless devices that don't need cabling job, but still need a place to supply power to the device.

Q: I found some suspicious devices, can I block them?

A: Yes, you can enable or block the Internet access of the device.

Q: My warehouse / restaurant uses PAD for ordering, so it must not be affected by other users or devices. It can be connected to the system smoothly. Can it be done?

A: Yes, reserve the Internet address for the ordering equipment, and then put it on the dedicated "A" network, and then reserve most of the network resources to the "A" network.

Q: We need to apply for government Wi-Fi. HK funding, is there a suitable plan?

A: Yes, the WiFi service we provide meets the government's Wi-Fi. HK application requirements, including providing WiFi usage reports and maintenance services.

Q: What are Cat5e and Cat6 cables?

A: Cat5e (Category 5 enhanced cabling) is designed to support 1000 Mbps (gigabit) network transmission speed (theoretical value), and it can also reduce the signal interference (crosstalk) inside the network line, so that the transmission speed can be faster Faster and more stable. Cat6 (Category 6 cabling) is the next improved version of Cat5e. The transmission rate can reach 10 Gigabit. With the rapid development of 5G and Wi-Fi 6, Cat6 cabling has become more and more popular.
