no body can use your wifi even if it has the password ~ DepoTech

Hacking a wifi is easy to achieve if you have not properly configured and secure your network. Even some too old encryption protections (WEP) or more recent but poorly used (wpa) will not withstand more than a few minutes if not properly configured.

Securing your wireless network is a necessary step to prevent a malicious user from using your wireless network son. Here are the steps to follow.

Change the user password of your wireless router

Access to the configuration utility for your router is secured with a username and a password. This page is accessible by typing the IP address of your router in your browser (eg 192.168.1.1). The first step in securing your new Wi-Fi network is therefore to change the password by going to the option to change it.

Set your network name (SSID)

All wireless network has a name: the SSID (Service Set IDentifier). The second step is to change the name and conceal it from view malicious users. In your router's configuration utility, change the default SSID name in avoiding it is too simple.
Then turn off the broadcast of SSID of your wireless network by checking the box, so it does not appear in the list of possible connections of your neighbors.

Enable encryption on your network (security key)

Before using your wireless network son, it is useful to encrypt it with a digital key in order to leave access for users with it. Two data encryption types are currently available: WEP (Wired Equivalent Privacy) and WPA (Wi-Fi Protected Access). If your router and all your adapters without-son support it, we recommend that you opt for a WPA key encryption key with "Pre". However, if your hardware does not support WPA, then select WEP encryption. The handling is simple because the digital encryption is created from a sentence: you need to enter a password of at least 5 letters or phrase in the text box and the router will generate different codes. Do not forget to rate them (one is enough) because they will be used to connect each computer on the network.

Filter MAC addresses

Remember, a MAC address is a unique identifier number assigned to any type of computer or electronic equipment, whether a PC, game console, smartphone, etc. With flitrage MAC addresses, you can actually determine what devices are allowed to connect to the network, to outlaw all others.

In your router's configuration utility, you must activate the filter option and enter the MAC addresses of each of your devices. And only these devices (known on the network by MAC address) can access the network. no body can use your wifi even if it has the password.

If you want to know the MAC address of a device read THIS POST: Find the MAC address of ANY mobile device (Mac Laptop, iPhone, iPad, Android, windows)

Disable automatic IP addressing

When a material wants to connect to the access point (box, wifi router ...), it automatically assigns a local IP address. This handy feature called DHCP (dynamic addressing IP address) will assign itself an address to each device connected to the network.

In order not to make it easier for an intruder, you can disable the DHCP of your box or router. It will in this case manually assign a local IP address consistent with that of your access point to each of your computers. To know what the IP address assigned one refers to the IP address of the access point. If your box or router has an address of 192.168.0.1 computers to a single address is 192.168.0.2 and 192.168.0.3 award in etc ... so this is the last set of digits after the last dot (.) That changes.

Configure Wifi device

For each device can connect to the network you will need to indicate the information above. After searching for your wireless network son, you need to change the SSID to match the one you specified for the router. Then specify digital encryption key that was given you in router ocnfiguration utility. Once done, your device should connect to the router and the Internet.
