You can set up your wireless router like this

Wireless RouterIs it changed from a common household model to a powerful wireless router? Yes, this is possible, and the method described in this article can also be implemented without spending a penny. However, the first thing you need to understand here is whatDD-WRTFirmware? The following is an explanation:

Firmware concept for DD-WRT

1. DD-WRT Based on Linux System

First we need to understand the DD-WRT, because this is the core of this transformation. DD-WRT Based on Linux system, as we all know, Linux is extremely flexible, not only can run on large servers, desktops, can also run on a variety of small terminal equipment, which includes wireless router. DD-WRT is actually an embedded Linux for the use of wireless routers, it can be in the ordinary home wireless router to achieve thousands of yuan of enterprise-level wireless router function, not only that, because of the open source nature of Linux, therefore, the DD-WRT can even allow users to compile their own programs and freely expand the wireless router function.

2. DD-WRT from Cisco

In fact, the initial prototype of 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 source code of the WRT54G firmware was disclosed. With the increasing length of time, many wireless device enthusiasts have made great efforts to develop third-party firmware based on the source code, and then install it on the wireless router, to replace the firmware installed by the manufacturer on the product. The DD-WRT is the most brilliant one.

3. DD-WRT has become a widely used third-party firmware.

Today, DD-WRT has become the most widely spread among third-party firmware, which not only integrates more and more functions, but also has a large number of different versions, even for embedded processors of different manufacturers, the corresponding versions have been developed. In the eyes of wireless device enthusiasts, if you buy a wireless router, the first thing to do is to brush DD-WRT.

2, how to install DD-WRT?

Next we will talk about how to install the DD-WRT to the router, first of all, you need to pay attention, although the current DD-WRT can be installed in the use of BROADCOM, GENERIC, MOTO, the three manufacturers of the processor wireless router, but the user in the installation before, or first determine their own products in the hands of the installation of DD-WRT, so as to avoid the wrong installation and damage. It is best to take the vro apart and check the tag on the processor. Now let's install DD-WRT step by step.

STEP 1, download the DD-WRT file, connect to the wireless router

First of all, of course, download the corresponding DD-WRT, after a long period of development, the current DD-WRT has developed a variety of versions, and different brands of different models of wireless routers can use the DD-WRT is not the same, some products because of the Internal FLASH capacity and other hardware differences may only use PRO special edition or MINI pocket edition, so be sure to download the DD-WRT firmware suitable for your own products, can not be mixed and wrong. You can query the relevant information on the network and select a suitable version for the wireless router. The latest version is v24 rc3, but v23 sp1 and v23 sp2 are recommended for better compatibility.

The downloaded DD-WRT is a file suffixed with. bin, Which is unzipped to the computer's C drive for backup. The file name of the DD-WRT is generally complicated, and can be changed to a simple name for convenience during the installation process, for example, here we name it "DD ".

Note: The identifier next to the plug-in must be a LAN port.

Connect the LAN ports of the computer and the wireless router with a network cable. Remember, you must use a network cable instead of a wireless connection. Because the router is refreshed during startup, the wireless module does not work during this process. Therefore, a wireless connection may cause a refresh failure.

STEP 2: Set the IP address and enter the command

After the connection is completed, the router is first restored to the original factory settings. For details, refer to the vro instructions. Then you need to manually set the IP address of the computer to a fixed IP address. For example, the default IP gateway of most wireless routers is 192.168.1.1 and the subnet mask is 255.255.255.0. In this case, the IP address of the computer can be set to 192.168.1.2.

Note: manual IP address setting is required

After completing these tasks, click "start" menu-"run"-type "CMD" and click "OK" to go to the command line mode. Enter "cd" and press Enter. Then, the system jumps to the root directory of drive C. At this point you can type "dir", you can see that the DD-WRT file you just placed is here.

After confirming that the DD-WRT file is on drive C, type the command: "tftp-I 192.168.1.1 PUT DD" where "192.168.1.1" is the IP address of the wireless router, "DD" is the name of the DD-WRT file, the user pay attention to fill according to the actual situation. But remember: Do not press enter after entering this command! Otherwise, all the work will be done.

Note: Do not press enter immediately after entering the command

STEP 3. Unplug the power and press Enter.

Next, you need to unplug the power of the router and plug it in later. At this time, you should note that when you plug in the power, you should look at the indicators on the router, first of all the LAN ports will be on, however, only the LAN port lights connected to the computer continue to be on, and other lights will flash out.

When other lights are destroyed, press the Enter key on the keyboard quickly. At this time, the file starts to be transmitted, and the LAN indicator of the wireless router will flash frequently for about 6 seconds. Then, a "Transfer successful: 3502080 bytes in 5 seconds" will appear on the screen, 700000 bytes/s "Success prompt. If you press enter late, an error message will be displayed after a period of waiting. You only need to repeat it and it will not affect the vro.

Step 4: Wait for about 4 minutes.

After "Transfer successful" appears on the screen, it will take about 4 minutes. do not perform any operation in the middle. Later, set the IP address of the computer to be automatically obtained. At this time, the computer should obtain a 192.168.1. × address, and the gateway and subnet mask will remain unchanged. Open IE and enter 192.168.1.1 in the "Address Bar" at the top. The username is root and the password is admin. Then the DD-wrt interface appears. So far, the installation of DD-WRT is complete.

Note: The user name has been changed to "root", the main interface of the DD-WRT, the models listed in the table can install DD-WRT

3. After installing the firmware of the DD-WRT, many functions are added.

After installing the DD-WRT, the performance of the router will be improved, and will also add a lot of new features, such as the user can easily implement the timing switch of the wireless router; the transmission power of wireless signals can be adjusted to increase the signal strength and coverage area. BT Downloads can be used to break through the Intranet and idle. bandwidth can also be optimized by setting QoS, speed limit, and number of connections, for example, blocking BT, donkey, and thunder. You can even enable the relay function of a wireless router, which is only available for enterprise-level products!

Note: Fill in the data in a space to change the transmit power.

In addition, there are some unfamiliar functions for common users, such as DDNS that supports peanut shells to facilitate the establishment of personal websites; PPTP clients that support VPN and PPTP server settings can provide VPN access; supports UPNP and port ing. Supports multiple languages and can be used with 802.1X Protocol, EAPExtensible Authentication Protocol, and Extensible Authentication Protocol) to add Network Authentication applications. Supports IPv6 and SNMP protocols, SSH service. The most important thing is that users can have all these dazzling functions without spending any money. The enabling of the relay mode is also very convenient.

Note three points during the refresh process: to ensure the refresh is successful, there are two tips:

1. During the refresh process, disable anti-virus software because unnecessary virus detection interrupts the upload of the installation file to the vro.

2. Disable all wireless adapters in the system, especially for laptop users, to ensure that the firmware is uploaded over a wired network.

3. Maintain the power-on status of the vro during the refresh process. unexpected power failure may cause damage to the vro.
