1. Understand the firmware
The most widely used flash firmware in China is the DD-WRT and TOMATO, both of which are the best in terms of functionality and stability. On the Internet, many third-party firmware files are released after the two firmware files are modified or updated. For example, DualWan firmware files are developed based on the TOMATO firmware files.
Therefore, whether a wireless router can brush the firmware, the key to see whether it supports DD-WRT or TOMATO firmware.
2. Which devices can be used for flash?
First introduce the DD-WRT and TOMATO's past and present, DD-WRT is based on the improvement of Linksys's wireless router firmware, so in a sense, the DD-WRT is Linksys Wireless Router compatible firmware; while TOMATO is improved on the basis of DD-WRT.
Therefore, all wireless routers of Linksys should be able to be flushed, because there is no compatibility problem. On the other hand, many wireless routers released by some foreign manufacturers also support flash brush, such as some Buffalo products, some Belkin products, some Motorola products, and some Asus products.
However, D-LINK and TP-LINK are two mainstream domestic wireless router manufacturers of early products can not brush DD-WRT or TOMATO firmware. This is because the firmware programs they use are not compatible with firmware such as the DD-WRT. Now, some new products support D-LINK brush, and TP-LINK new products have been unable to brush.
About can brush DD-WRT firmware problem, it is best to visit its official site for query, address is http://www.dd-wrt.com/dd-wrtv3/dd-wrt/hardware.html.
3. What are the requirements for flash brush?
In addition to the need to pay attention to whether the product supports DD-WRT and other firmware, in the brush machine before the need to know the FLASH capacity of the wireless router flash rom ). For a wireless router, flash memory is equivalent to its hard disk. When installing the system for a general computer, we need to leave enough space for the C drive, as is the case for a wireless router to flash the machine. We must ensure that the flash memory capacity of the wireless router is larger than the firmware capacity to be flushed. When the device flash memory is small or does not support the full version of the firmware, it is appropriate to select the MINI or MICRO version.
How can I query the hardware information of a device? The common method is to log on to the device management interface, find the system information under the "status" tab, and view the available memory resources and flash memory capacity of the current device in the "Memory" area.
