Wicked Free Wifi
Gordon Neal
I have noticed that when I go to connect to my wifi on my home network, a new Wifi appeared with identical signal strength but with the addition of the number 2 in the wifi name. Both are encrypted wireless networks and both have the same password but different mac addresses...
I have checked three other computers on the same network, and 2WIRE237 2 does not appear. In addition, although 2WIRE237 2 is "secure" (see photo), for some reason my computer automatically knows the password. I can connect to 2WIRE237 2; meanwhile, the network does not appear for anyone else using the network. Why?
I have read that hackers can utilize this method to gain access to computers. How can I determine if this is a Evil Twin attack? Does it appear so? What programs are user friendly to determine this? I have downloaded EVILAPDEFENDER; however, I am not a technology genius and I do not know how to install the program or run python.
It is also a good possibility this wireless network name has been used previously on a different device, and now Windows sees the BSSID is different, so it considers it a different network with the same name. You can list the wireless profiles your computer knows about with the command: netsh wlan show profiles
NetworkManager is a program that manages the primary network connection and other connection interfaces. NetworkManager has been designed to be fully automatic by default. NetworkManager is handled by systemd and is shipped with all necessary service unit files.
If you use NetworkManager for network setup, you can easily switch, stop, or start your network connection at any time. NetworkManager also makes it possible to change and configure wireless card connections without requiring root privileges.
wicked also provides some ways to switch, stop, or start the connection with or without user intervention, like user-managed devices. However, this always requires root privileges to change or configure a network device.
Both wicked and NetworkManager can handle network connections with a wireless network (with WEP, WPA-PSK, and WPA-Enterprise access) and wired networks using DHCP and static configuration. They also support connection through dial-up and VPN. With NetworkManager, you can also connect a mobile broadband (3G) modem or set up a DSL connection, which is not possible with the traditional configuration.
NetworkManager tries to keep your computer connected at all times using the best connection available. If the network cable is accidentally disconnected, it tries to reconnect. NetworkManager can find the network with the best signal strength from the list of your wireless connections and automatically use it to connect. To get the same functionality with wicked, more configuration effort is required.
Even though NetworkManager and wicked are similar in functionalities, we cannot guarantee full feature parity. The conversion of the wicked configuration or automated switching to NetworkManager is not supported.
The /etc/sysconfig/network/ifcfg-* files are usually compatible except for some rare cases. But when you use the wicked configuration located in /etc/wicked/*.xml, you need to migrate the configuration manually.
NetworkManager provides a sophisticated and intuitive user interface, which enables users to easily switch their network environment. However, NetworkManager is not a suitable solution in the following cases:
After enabling NetworkManager in YaST, configure your network connections with the NetworkManager front-end available in GNOME. It shows tabs for all types of network connections, such as wired, wireless, mobile broadband, DSL and VPN connections.
Depending on your system setup, you may not be allowed to configure certain connections. In a secured environment, certain options may be locked or require root permission. Ask your system administrator for details.
Visible wireless networks are listed in the GNOME NetworkManager applet menu under Wireless Networks. The signal strength of each network is also shown in the menu. Encrypted wireless networks are marked with a shield icon.
A wireless network that has been chosen explicitly remains connected as long as possible. If a network cable is plugged in during that time, any connections that have been set to Stay connected when possible will be connected, while the wireless connection remains up.
NetworkManager supports several Virtual Private Network (VPN) technologies. For each technology, openSUSE Leap comes with a base package providing the generic support for NetworkManager. Besides that, you also need to install the respective desktop-specific package for your applet.
To enable the connection, in the Network panel of the Settings application click the switch button. Alternatively, click the status icons at the right end of the panel, click the name of your VPN and then Connect.
NetworkManager distinguishes two types of wireless connections: trusted and untrusted. A trusted connection is any network that you explicitly selected in the past. All others are untrusted. Trusted connections are identified by the name and MAC address of the access point. Using the MAC address ensures that you cannot use a different access point with the name of your trusted connection.
NetworkManager periodically scans for available wireless networks. If multiple trusted networks are found, the most recently used is automatically selected. NetworkManager waits for your selection in case if all networks are untrusted.
If the encryption setting changes but the name and MAC address remain the same, NetworkManager attempts to connect, but first you are asked to confirm the new encryption settings and provide any updates, such as a new key.
User connections require every user to authenticate in NetworkManager, which stores the user's credentials in their local GNOME keyring so that they do not need to re-enter them every time they connect.
If you do not want to re-enter your credentials each time you want to connect to an encrypted network, you can use the GNOME Keyring Manager to store your credentials encrypted on the disk, secured by a master password.
By default, connections in NetworkManager are device type-specific: they apply to all physical devices with the same type. If more than one physical device per connection type is available (for example, your machine is equipped with two Ethernet cards), you can tie a connection to a certain device.
To do this in GNOME, first look up the MAC address of your device (use the Connection Information available from the applet, or use the output of command line tools like nm-tool or wicked show all). Then start the dialog for configuring network connections and choose the connection you want to modify. On the Wired or Wireless tab, enter the MAC Address of the device and confirm your changes.
When multiple access points with different wireless bands (a/b/g/n) are available, the access point with the strongest signal is automatically chosen by default. To override this, use the BSSID field when configuring wireless connections.
The Basic Service Set Identifier (BSSID) uniquely identifies each Basic Service Set. In an infrastructure Basic Service Set, the BSSID is the MAC address of the wireless access point. In an independent (ad-hoc) Basic Service Set, the BSSID is a locally administered MAC address generated from a 46-bit random number.
The primary device (the device which is connected to the Internet) does not need any special configuration. However, you need to configure the device that is connected to the local hub or machine as follows:
Connection problems can occur. Common problems related to NetworkManager include the applet not starting or a missing VPN option. Methods for resolving and preventing these problems depend on the tool used.
If you have configured your network connection correctly and all other components for the network connection (router, etc.) are also up and running, it sometimes helps to restart the network interfaces on your computer. To do so, log in to a command line as root and run systemctl restart wickeds.
