The mobile phone has the Wi Fi password in the store, but it was blocked, how to get it

That's kicked by the shopkeeper, look!

(1) Ask him for a password (2) See if others share the hotspot.

This is the only way to ask for the password of someone else's house.

Defensive measures to prevent others from rubbing the net.

1. WPA WPA2-PSK encryption is adopted.

2. Disable the SSID (network name) broadcast.

The setup method is very simple, go to the web configuration interface of the wireless routing AP, then find the "Basic Settings" menu, modify the SSID name in it, then select "Disable SSID Broadcasting", and finally click OK.

3. Disable the DHCP function.

4. Set MAC address filtering.

MAC address filtering is a very critical step in the overall setup to prevent "surfing". We take advantage of the uniqueness of the MAC address of the network device, by setting the "Allow MAC address connection" list, only the clients in the list are allowed to connect to the wireless network, so that even if the wireless key is cracked, the "rubbing the network" still cannot connect to your wireless network.

MAC address filtering is generally in the "Advanced Settings" menu of the wireless routing AP, we only need to enable the MAC address filtering function, and enter the MAC address of the client device that is allowed to connect into the list, and finally click OK.

So how do you check the MAC address of a client device? It's very simple, we just need to click "Start" "Run" and enter "cmd" Enter, and enter "ipconfig all" in the command prompt interface that appears, and we can get the MAC address of the client.

5. Modify the internal IP settings.

If you don't feel safe enough, then you can go ahead and set it up. First, shut down the DHCP server. DHCP can automatically assign IP to the wireless network, which also makes it easier for the Internet users to access your router after cracking your key.

After turning off DHCP, your computer's wireless network card needs to be manually assigned to the IP, don't worry, let's change the internal IP of the router first.

Generally, the default IP address of the router is the gateway address, and we change the address to any intranet address, for example, so that the internal computer can specify the IP as the network segment. In this way, the average Internet user will not be able to figure out the IP settings of your intranet at all, and they will not be able to assign IP to themselves to surf the Internet.

This completes our overall protection setup. Under the protection of this overall protection solution, it will be difficult for ordinary "surfers" to invade your wireless network, your network will be restored to its previous smoothness, and your data information will become more secure.

The setting of the router is nothing more than setting the wifi password, psk mode, but if you don't want others to crack it easily. Please set a more valid WiFi password.

Here's how to set up a more secure password scheme:

1.Change the router login password, the default password is mostly admin, it is recommended to change and do not be the same as the wireless network password.

2.Do not use WEP encryption, use WPA-PSK or WPA2-PSK encryption.

3.Enhance the complexity of passwords, such as "adf6%i*hsj", wpa-psk or wpa2

It is still relatively safe and can only be guessed by brute force, in which case the security of the password is directly proportional to the complexity of the password.

5.Decisively turn off QSS and WPS, this function has not been used by most people, but it hides a huge loophole, because the PIN code is only 8 digits, it is easy to be brute-forced, get the PIN code, and change the password countless times to no avail.

6.If you really don't want to turn off QSS and WPS, then set a PIN limit.

Address filtering,It should be a very effective trick,Turn off DHCP,Add MAC address whitelist and bind IP,Even if the password is leaked, others can't get on it。

With a computer that can access the Internet, open a web page, address input or, a dialog box will pop up, enter admin, password admin, enter the router settings and look at the wireless settings, there is a password for wireless connection in the security settings, don't move the others!

With WPA password mode, it is difficult to crack the password.

You can install third-party applications, such as WiFi Manager, WiFi Man password viewing, etc., provided that the phone needs to be rooted

Simple, but not all of them will be successful, adopt the software I hand over to you.

Set up MAC address filtering, no one can use the Internet without setting a password.

The wifi signal of the wireless router will always be connected by someone, even if the password is set, there is a brute-force cracking software can also be cracked, connect to your own wireless route, and seize the network. Here we need to use the wireless router's built-in setup tool to set up, only allow the specified computer to connect to the wireless router to prevent others from rubbing the network.

Method steps.

1. First log in to the wireless router management page, enter http in the browser: followed by the IP address of the router, (this address is not fixed, generally check your own default gateway is the address of the management page).

After entering, a dialog box will pop up for you to enter the user name and password, the settings of different router manufacturers in this place are different, you can refer to the instruction manual (the general user name is admin, the password is empty or admin).

2After entering the management page, there is a menu bar on the left, and you can find the Wireless MAC address filter option. Once clicked, the homepage will show you the wireless MAC filtering settings.

3 General MAC address filtering function is turned off by default, we click Enable Filtering to start it. There are options below, Forbidden. and allowed.

Generally, if we don't want others to rub the network and only allow a few people in the LAN to connect, then select Allow, and then add the allowed MAC address in the following entry.

Once set up, our wireless network can only be used by the people who set it up.

Then whatever you set up, in fact, it's good to change the password, and don't use anything else!

Restore factory settings. Set up the router from the new and put the honey code to the service noise.

Open ** enter to set up and change your password! The most common username and password is admin

You can bind an IP address or limit the number of logins, etc., and try to change the password as complicated as possible.
