DD-WRT refresh firmware

I. preparations:

Our purpose is to refresh the firmware driver of the existing wireless router into a DD-WRT, so there is a certain risk in the refresh operation, the author has accidentally broken two wireless products, the final result can only be returned to the factory for repair. Therefore, we must make good preparations and do not worry about the refresh process, because it takes several minutes to update the wireless router after the refresh, and the network will fail during the update process, when the signal lights flash, do not turn off the power for refreshing failures; otherwise, the device will be damaged.

Before refreshing the firmware driver of the DD-WRT, we need a computer (Windows, Linux, Mac, any system can be), of course, the most we use Windows, you need to activate broadband network connection ADSL, cable, etc., need a support brush DD-WRT wireless router; need to download the corresponding DD-WRT driver in advanceProgram.

Note: Here it is worth noting that different brands of different models of wireless routers may use different DD-WRT drivers, some of the Internal flash capacity and other hardware differences may only use pro special edition or mini pocket version, so we must download suitable for your own product DD-WRT firmware driver, not mixed and wrong.

Ii. device introduction:

The basic situation of the Motorola wr850g wireless router I purchased is as follows:

CPU: Broadcom 4712 (200 MHz)
Wireless Module: 4306 (B/g)
Flash: 4 m (32 Mbit, the flash chip model is the best intel te28f320)

Switch chip: ADM 6996l (supporting VLAN Virtual LAN perfectly)

By default, Motorola wr850g wireless router has the same features as most other wireless products, of course we want to refresh him into a DD-WRT firmware driver is to give him more and more powerful features, after the refresh, our Motorola wr850g wireless router will have multiple features that were not previously available, and the operation stability and effect will be greatly improved, the extended functions include customizable ddns, VLAN division, QoS, and so on.

In addition, I also need to remind you that the device uses a 12 V power supply, You must select a suitable power adapter for power supply.

Three, step by step refresh DD-WRT firmware driver:

I use is suitable for Motorola wr850g wireless router DD-WRT driver firmware V23 SP2 version. The firmware file size is 2.44 MB. The default Management connection IP address of the Motorola wr850g wireless router is 192.168.10.1. When refreshing, we need to connect to this IP address with our computer.

Step 1: because our management and connection IP address is 192.168.10.1, we set the IP address of our computer to 192.168.10.2 and the subnet mask to 255.255.255.0. The gateway address can be 192.168.10.1 or left blank. After the configuration is complete, connect the power of the wireless router device, and connect the network adapter of your computer and any LAN interface of the wireless router.

Step 2: At this time, we need a TFTP transmission tool to send the driver to the wireless router. There are many TFTP transmission tools available on the Internet. We can download one at will. Start the TFTP tool and enter 192.168.10.1 at the server. click the button next to the file to find the driver file to be refreshed. (Http://wireless.it168.com /)

Here we provide the TFTP tool and the moto DRIVER:

TFTP tool: Driver for local Moto: Local

Since we want to refresh this router into a DD-WRT driver, choose the DD-WRT driver that fits our Motorola wr850g. Generally, the firmware drivers of a wireless router end with. bin, and the capacity is not too large. You can find the brand and model of the driver by using the previous name.

Step 3: If we click the "Upgrade" button below at this time, "unable to get responses from the server" will appear, and the software will try three times in a row. This means that we have not successfully connected our computer to the wireless router, or even the connection has not reached the refresh level. If you want to refresh the page and click the "Upgrade" button, it will be advantageous. Otherwise, an error message will appear. Before refresh, we must re-enable the wireless router, unplug the power, and confirm that it is correct. In addition, during the firmware driver file refresh process, you must note that the power cannot be interrupted or shut down abnormally. Otherwise, the refresh will fail and you can only return to the manufacturer for repair. Therefore, you must be careful when refreshing the driver.

Step 4: After the wireless router restarts, it will look at the router lights. First, all the LAN ports will be on, and then, in an instant, only the LAN port connected to your computer is lit. At this time, you will not hesitate to press the "Upgrade" button. After a while, the message "firmware was upgraded successfully" appears, indicating that the data is successfully refreshed. Many readers cannot grasp this opportunity. In fact, before restarting the vro, we can choose "start"> "run"> "Enter cmd" in the operating system taskbar to enter the command line mode, in command line mode, use "Ping management connection IP address-T" to check and restart the router. When the Ping is displayed for the first time, press the "Upgrade" button, in this way, we can achieve success.

Step 5: Next, you will see all the display lights of your wireless router flash, and the router will be restarted again and again. Please wait for at least 3 minutes. The router cannot be powered off, do not perform any operations on the vro. Of course, if you enter the "Upgrade" button, it will be too late. After a period of waiting, an error message is displayed. You only need to repeat it and it will not affect your vro. After three minutes, we can set the IP address of our computer to automatically obtain the network parameter information provided by the wireless router. (Http://wireless.it168.com /)

Step 6: because the management IP address of the DD-WRT-driven broadband wireless router is 192.168.1.1, we open the browser and enter this address in the address bar to see his management interface, at login, enter the default user name is root, password is admin, so far we have successfully completed the Motorola wr850g to refresh the DD-WRT firmware driver operation.

But in the end we refresh the DD-WRT wireless device in which functions have been improved, how to achieve these functions? In the next articleArticleWe will introduce several examples of powerful DD-WRT wireless devices than ordinary wireless routers.
