8: Weak or no Wi-Fi security settings
Even though many people now know that open Wi-Fi networks are a big security risk, there are still many families or businesses that keep their wireless networks open and insecure. In addition, because of the popularity of WEP encryption, there are still many networks using this encryption au
To remove Tp-link security prompts, you need to set up encryption first
Basic Tp-link All models of wireless routers have increased the anti-RUB Network security prompts page, which is to resist the increasingly rampant behavior of the network, reminding the vast number of Tp-link users pay attention to wireless network security. As shown in the following figure;

In the lower-left corner of the Win7 desktop, click the Start button-> and then click Control Panel-> Open Network and Internet. Then click Network and Share center-> to set up a new connection or network "->" to set up a new network.
There are currently three types of wireless network encryption: WiFi Protected Access (WPA and

Problem:
1. ssh_host_dsa_key and ssh_host_rsa_key are lost.
2. You are not authorized to access these two keys.
The solution is as follows::
1. When two keys are lost:
Enter ssh-keygen-t dsa-F/etc/ssh/ssh_host_dsa_key in the terminal to recreate the ssh_host_dsa_key file.
The following information is returned:
