control level of existing wireless LAN systems can be greatly enhanced; WPA enhances the algorithm for generating encryption keys, even if hackers collect and parse group information, it is almost impossible to calculate a general key. The emergence of WPA makes network transmission more secure and reliable.

In short, the SSID is the name you give your wireless network. When searching for a wireless network, your network name is displayed in

It should be noted that the wireless encryption function is usually disabled when a wireless router leaves the factory, but if you give up this function, your network is an extremely insecure network, therefore, we recommend that you enable this function after setting it.

Since 2013, a wave of intelligent trends began to sweep the entire Internet, followed by countless popular smart hardware, one of which is routers. However, it is a pity that intelligence is not the correct direction for the development of routers. It is just a selling point discovered by the router manufacturers. This year, the concept of smart routing has gradually vanished with the user's rational experience, but the journey of Rout
The rapid development of the Internet has brought great convenience to our lives and work. People are getting increasingly accustomed to having Internet. With the continuous improvement of network technology, it is no longer a new thing to build a wireless network in the family. However, many consumers do not know how to set up a wireless network after they buy a wireless route. Today, we will build a wireless network together with everyone.
Before assuming the network, let's take a look at the
DD-WRT was released by Cisco, the originator of the router, and was carried on the WRT54G Wireless Router launched by Cisco's Linksys, supporting the highest 54Mbps connection speed at that time. Soon, some enthusiasts discovered that WRT54G firmware is based on Linux. However, the source code must be disclosed as a basic condition for using Linux as the operating system. After this incident was spread, Cisco was under public pressure, finally, the s

Some small size USB flash drives are too small to use, and it seems a pity to lose them. However, after a small transformation, we can use our computer to get a powerful router, which not only saves the money to buy a route, but is basically unavailable on the market!
About DD-WRT
Each router device we use usually has its own operating system OS, which is used to set and manage various functions of routing devices. In fact, what we usually call upgrading the router firmware is to update and refr
the kernel, so that we can control the OpenWrt later through the web, rather than through the command line control. So add the following command: ./scripts/feeds Update Packages Luci ./scripts/feeds Install-a-P Luci After that, the Luci option appears when the kernel is compiled. Since I don't have a Linksys series router and just to experience OpenWrt, I've compiled openwrt into a VMware workstation disk image, using VMware Workstation to emulate a

If you are connected directly to the Internet (e.g., cable,dsl,t1), it is recommended to turn it on. If you use a hardware firewall (for example: D-link,netgear,linksys, etc.), you can turn it off.

Only the wireless router on which the Telnet service is turned on can be set up using this method.

Since the wireless device cannot find another WPS wireless device that can be automatically negotiated when the WPS function is turned on, he will stop the search, but the key is no longer recovered in the process.

Because of this we can take the WPS button as a wireless network switch, of course, not all wireless rout

Of course, the wireless router requires an AC outlet and a connection to your cable or DSL data source. If the building's DSL or cable modem lines are in an inconvenient position, please don't panic, you can use directional antennas (we'll mention the next serial article), or extend your DSL and cable lines.
If you choose the latter, you will find that the wall-broken wiring is a laborious and costly project to keep your router in the right place and can cause damage

Now, OneCare provides a convenient and unlimited Network Setup Wizard that guides you through configuring wireless network protection and then connecting clients to the network. This is important because there are many completely unprotected wireless networks: it is clear that the tools that accompany network devices are too complex for the averag

(2) Reject DHCP packets:
The DHCP service can help us to automatically assign IP addresses to computers in the network, but in practice DHCP can cause network instability, such as when the lease is reached again and the IP address is already in use by other computers on the network, or DHCP information is frequently negotiated between the computer and the wireless router.
For average home users, the number of computers in the network is
