Resolution of the problem that the Wi-Fi password cannot be accessed after being cracked

I just want to give a brief introduction to the problem that I cannot access the Internet after cracking the wireless route password. For reference.

After Using BT or bottle to crack the wireless route password, you can find that the network adapter is restricted or cannot obtain the IP address.

The most common reason is:

I. The host configures MAC filtering in the routing firewall.

In this case, you need to first set up a local area network IP address (for example, 192.168.1.100), then use the kice Network Analysis System to sniff out the IP addresses and MAC addresses of active hosts in the local area network. Record These MAC values, and then use the software such as KMAC to modify the NIC address to modify the MAC address of the local machine. Through such forgery, the Internet is generally accessible. However, if you are able to access the Internet, those who have stolen your MAC will not be able to access the Internet. Therefore, after forging a MAC address, it is best to avoid peak traffic or intrude into the route as soon as possible to add your real MAC address to the firewall of the route.

Ii. DHCP not enabled

If the host uses a manual IP address, you cannot connect to the route after cracking. At this time, what you need to do is to use the kice Network Analysis System to sniff out the IP addresses and Gateway Addresses of active hosts in the LAN. Then, manually set the IP address of your local machine based on the IP address segment. After the IP address and gateway are set, the most important step is to set up DNS. This is critical. The key to connecting to the internet is here. This DNS goes to Baidu on its own, and each province is different. For example, the DNS in Fujian is 218.85.157.99. After these settings are complete, you can access the Internet normally.

Of course, MAC filtering and DHCP are used in many cases. Therefore, when a wireless password cannot be connected, you need to analyze the result of the multi-disciplinary sniffing. Analyze the problem by capturing packets
