With the increasing popularity of routers, routers have entered thousands of households, but with the upgrade of system software, is your router also keeping pace with the times? The following system home Xiaobian tells everyone how to upgrade the router firmware to improve performance? Like smart devices such as PCs and tablets, routers also come with their own operating system, which is what we call router firmware. In order to fix the bugs in the old version and improve the performance of the device, the router manufacturer will introduce new versions of the firmware from time to time. Therefore, we only need to update the firmware in time to let the router achieve the best performance. . In addition, for routers that do not provide firmware updates, we can also improve performance by brushing in some third-party firmware, such as DD-WRT. 1. Use the official firmware update to enter the router settings interface, select the “System Tools & Rarr; Software Upgrade” on the left side. On the right side, we can see the software and hardware version currently used by the router, and write down the hardware version. Information (in this case WR740N v3/v4. Figure 1). Then, in the browser to search with the "WR740N v3/v4 firmware" keyword, the relevant firmware update information will appear. Go to the corresponding website and download the corresponding firmware file to the local (Figure 2). In the interface shown in Figure 4, click the "Browse" button in the "File" box on the right side to open the corresponding dialog box, select the firmware you just downloaded and confirm, and finally click "Upgrade" & rdquo ; button, wait about 20 seconds or so, the upgrade work is completed. After the upgrade is completed, the router will automatically restart. Now, if the Wi-Fi transmission rate is improved, the number of settings in the setup interface will increase, and the connection status of the network will be more stable. Tips: What new features does DD-WRT bring to us? Support 3322.ORG and peanut shell DDNS; can use QoS, speed limit, limit connection number and other settings to optimize bandwidth; support VPN PPTP client and PPTP server settings, can provide VPN access; can easily implement wireless devices Time switch; easy to manage various network applications through configuration, such as completely blocking BT, eDonkey, Thunder; support UPNP and port mapping; support IPV6, SNMP and SSH services support multi-language, can be used with 802.1x (EAP (Extensible Authentication) Protocol) - Extended authentication protocol encapsulation on the LAN to increase network authentication applications. 2. Updating DD-WRT with DD-WRT is a very famous third-party firmware. It can support more functions than the manufacturer's own system. However, although DD-WRT is very powerful and supports many brands of routers, it does not mean that it supports all routers, so before the official opening, we should first go to its official page to find out if your device is listed. First, query whether DD-WRT supports its own routing device. Go to the http://dd-wrt.com page and click on the Route Database button (Figure 3) on the right to switch to the corresponding page. Click the model and software version corresponding to the router. In the page that appears, you can see the FLASH capacity of the router. In the list below, you will see the firmware information for the router (two types). File for BIN) (Figure 5). These two files are named after Factory—to-ddwrt, one is started with TL or other letters, the former is suitable for the first time to brush DD-WRT from the original equipment, the latter is suitable for the existing DD - Upgrade in the WRT version. Since we are here for the first time to brush the DD-WRT for the router, just click on the download link of the Factory—to-ddwrt file to download the file. Where can the wireless router be placed without a dead end: http://www.xp85.com/html/article-98-2107.html Next, enter the router settings interface (the router and PC are connected by the network cable), click on the left side & ldquo; system tools & rarr; restore factory settings & rdquo; items, restore the router to the factory settings. In the same way as above, click the “System Tools & Rarr; Software Upgrade” item on the left side, and then in the right pane, select the file to be upgraded as the BIN file just downloaded, and return to the router management interface. Click the “Upgrade” button to complete the DD-WRT brushing process. This article comes from [System Home] www.xp85.com
