\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\twhat? Does wireless routing have no password? Is this reliable? The following system home introduces how to rely on the router's default password or some simple and easy to remember passwords, or even without access passwords, can invade and hackers. Many friends forget the router login password or wireless connection password for the sake of security. They use a more complicated password, or are misled by some articles, and will change the password every other day. In fact, routers are different from other network services that rely on passwords to ensure security, such as QQ and forum accounts. In addition to password protection, they also provide a lot of security measures. With these measures, we only rely on the device's default password. Or some simple and easy to remember passwords can keep invaders and netizens out. So fundamentally, solve the problem that the password is easy to forget. Login password, the default router will bring a set of default login information when it leaves the factory. This information will usually be marked on the product manual. If we use this information to log in, naturally, the login password will not be forgotten. (Even if the manual is lost, you can find relevant information through the network search). The question now is, how do we ensure the security of the router settings while using the default information? In fact, we simply use the LAN WEBW management rules provided by the router itself to prohibit other network card management routers other than the specified network card. Take the TP-LINK WR740N as an example. Example 1: Only the local wired or wireless network card management router is allowed to connect the PC and the router with the network cable. At this time, even if the wireless card is inserted into the machine, the system will connect to the network by default by wired connection. Enter the router settings interface, select the "Security function & rarr; LAN WEB management" item on the left side, check the right side of the list, and only allow the MAC address in the list to access the WEB management page & rdquo; item, in the current management In the PC's MAC address, we can see the MAC address of the wired network card that is currently accessing the interface, click the “Add” button (Figure 1), and then click the “Save” button. You can add the wired native wired network card to the list of allowed MAC addresses. In the future, if you want to manage the router, you only use the network card and use a wired connection. When other PCs attempt to access it, the page will appear. The prompt for this page cannot be displayed (see Figure 2), causing the connection to fail. In the same way, unplug the network cable and use the wireless connection. We can also specify that only the local wireless connection can be used to manage the router. Example 2: Allow multiple network cards to manage routers at the same time. Of course, if you think that only a single network card management router is not insured (such as possible network card damage), you can also add the network card addresses of other PCs in the network to the allowed management list. Press the Win+R key combination in the PC that allows management, open the run dialog box, enter cmd (Figure 3), press Enter, enter the command prompt window, type ipconfig /all, press Enter, the wireless used for the machine The MAC address corresponding to the wired network card will appear in the "Wireless LAN Adapter Local Connection" and "Ethernet Adapter Ethernet" in the "Physical Address" item (Figure 4), record them. Then add it to the “MAC address 2”, “MAC address 3” text box as shown in Figure 1 and save it. Connection password, no wireless connection password is not good enough to ensure the security of the wireless network, because according to experience, with some popular network equipment, we can basically crack a connection password in 10 minutes. Therefore, such a password is not worth mentioning. So, how do we ensure network security without setting a password? It's also simple. On the left side of the router's settings interface, select “Wireless Settings & Rarr; Wireless MAC Address Filtering. On the right side, click the “Enable Filter” button to enable MAC URL filtering. Then in the "Filter Rules" item, we can easily shut out those nasty nets in two ways. First, in the case of knowing the MAC address of the network, we only need to select the MAC address other than the effective rule in the list to access the wireless network (see Figure 5), and then click “ The new entry & rdquo; button, enter the net address of the netizer into the "MAC address" text box, click the "Save" button (Figure 6), the address will never want to visit our network. Second, if we don't know the MAC address of the network, then we can select the MAC address other than the effective rule in the list to access the wireless network in the interface shown in Figure 5, and then use In a similar way above, the MAC addresses that are allowed to be accessed are added to the list. To see which MAC addresses of devices that are allowed to connect are simple (including smartphones, tablets, smart set-top boxes, etc.), first connect these devices to the wireless network, then in the router's settings interface, select “Wireless Settings → Host Status ”, the current number of devices connected to the network and their MAC addresses will appear (Figure 7). Let's see if the number displayed here matches the number of devices actually connected. If they match, it means that there is no net player at this time. Just write down these MAC addresses and add them to the allowed access list. If it doesn't match, it's dangerous. It allows the connected device to continually disconnect from the network and then reconnect, so that the devices in the list will disappear or appear constantly, so that the corresponding MAC address can be easily determined.
