固件(Firmware)是嵌入在路由器中的软件。它的固件帮助路由器弄清楚如何执行不同的任务。要更新它，您必须在路由器中刷新更新的软件。我们将告诉您为什么以及如何(how to) 更新路由器固件(update router firmware)以及在哪里获取更新。
只要有新的更新可用，您就应该更新路由器固件。这是因为最新更新将具有更好的功能，并且可能已修复先前版本固件中的安全问题。更新的路由器也有助于修复较旧的路由器软件错误。
如果路由器上的某些问题即使在重置后仍未解决，最好的办法是更新路由器固件。
通常，如果您从 Web 下载路由器更新，它会显示与固件相关的改进列表。您可以检查列出的改进，然后决定是否更新路由器固件。
最好的办法是定期检查更新。如果有更高版本，请使用它来更好地运行路由器。让我们看看如何在本文的下一部分更新路由器固件。
如何更新路由器固件
某些路由器，例如Google和Binatone，会在有可用更新时自行更新。对于其他路由器，您必须访问路由器网页以刷新固件。
要访问路由器，您需要一个有效的互联网连接和一台计算机。由于您将刷新路由器ROM以更新路由器固件，我们建议您使用以太网(Ethernet)连接，以便该过程变得更容易、更快和更安全。
如果无法使用以太网电缆，您可以使用(Ethernet)Wi-Fi。只需(Just)确保您的计算机和路由器在同一个Wi-Fi上。可以在Wi-Fi上运行 flash，但与(Wi-Fi)以太网(Ethernet)连接相比，所需时间会更长。这只是为了在您仍在更新路由器固件时互联网连接不会中断。
如何访问路由器的 Web 界面
我们将使用 Web 界面来更新路由器。跟着这些步骤
- 打开您的互联网浏览器
- 在地址栏中输入192.168.1.1 ；(192.168.1.1)它将打开路由器登录页面；如果 192.168.1.1 没有将您引导至路由器登录页面，请查看您的路由器支持手册以获取“ routerlogin.net ”等链接。在某些情况下，信息会通过背面或底部的贴纸提供你的路由器
- 所有路由器的登录都有默认值。您需要找到登录路由器的用户名和密码；使用以下组合，看看哪一种适合您：
- 用户名 admin(admin) ; 密码密码(password)（字符应始终为小写）
- 用户名 admin(admin) ; 密码管理员(admin)
- 用户名密码(password)；密码密码(password)
- 用户名 admin(admin) ; 密码1234
- 用户名 admin(admin) ; 密码0000
如果以上方法都不能帮助您登录，请重置路由器并重试。路由器上会有一个重置按钮。它也可以在路由器电源开关附近的小孔中。
插入(Insert)一个大头针以访问重置按钮（如果有孔）。按住重置按钮 5 到 10 秒，以便将路由器配置设置为默认值。重置路由器后尝试上述用户名和密码的值。
注意：(Caution:)重置路由器会将所有值设置为默认值。仅当您知道如何配置路由器时才 继续。(Proceed)
在哪里下载固件更新文件
路由器的型号将印在路由器上。它可以直接印在路由器的机身上，也可以印在背面和底部的贴纸上。记下它。
假设您的Internet浏览器已打开，请访问路由器制造商的网站。例如，如果是 NetGear，请键入https://www.netgear.com。从那里，通过单击相关菜单选项卡转到网站的支持(Support)部分。在大多数情况下，它被简单地命名为“支持”。
在路由器的支持页面中，必须有一个搜索栏。输入路由器型号，然后按 Enter 以接收与您的路由器相关的信息。同一页面应该有一个下载(Downloads)部分。查看最新的路由器版本并将其下载到计算机上的安全位置。
- 华硕路由器用户访问router.asus.com。
- Linksys 路由器用户去这里(here)。
- ARRIS路由器用户去这里(here)。
- NetGear 路由器用户去这里(here)。
- TP-Link路由器用户去这里(here)。
- D-Link 路由器用户去这里(here)。
刷机更新路由器固件
下载固件更新文件后，转到包含路由器登录的浏览器选项卡。
检查显示Upgrade、Admin或Firmware的选项。它在菜单上可以有另一个名称，但是当您单击它时，它会显示一个页面，要求您“浏览到文件”，其中包含一个文本框和一个显示“更新(UPDATE)”的按钮。
点击(Click)“浏览”。当打开文件的对话框出现时，导航到保存更新固件文件的位置，选择它，然后单击“OPEN”，然后单击“UPGRADE”按钮。
更新路由器固件需要一些时间，具体取决于路由器和计算机之间的连接类型。
更新完成后，路由器将重新启动，以便您获得更好的网络体验。

How to update Router Firmware
Firmware is the software embedded in your router. Its firmware helps the router figure out how to carry on different tasks. To update it, you have to flash updated software in the router. We’ll tell you why and how to update router firmware and where to get an update.
You should update the router firmware whenever a new update is available. It’s because the latest update will have better features and might have fixed security issues in the previous version of the firmware. An updated router helps in fixing older router software errors too.
If some problem on the router isn’t fixed even after a reset, the best thing is to update the router firmware.
Normally, if you are downloading the router update from the web, it shows a list of improvements related to the firmware. You can check the improvements listed and then decide whether to update the router firmware.
The best thing to do is to keep on checking for updates at regular intervals. If there is a later version, use it for better functioning of the router. Let’s see how to update router firmware in the next section of this article.
How to update Router Firmware
Some routers, like Google and Binatone, update themselves when an update is available. For other routers, you will have to access the router web page to flash the firmware.
To access the router, you need an active internet connection and a computer. Since you will be flashing the router ROM to update router firmware, we’d suggest you use an Ethernet connection so that the procedure becomes easier, faster and safer.
If Ethernet cable is not possible, you can use your Wi-Fi. Just make sure that your computer and router are on the same Wi-Fi. It is possible to run a flash on Wi-Fi, but the time taken will be longer as compared to Ethernet connections. It is just so that the internet connection doesn’t drop while you are still updating the router firmware.
How to access your routers’ web interface
We’ll use the web interface to update the router. Follow these steps
- Open your Internet browser
- Type 192.168.1.1 in the address bar; it will open the router login page; in case 192.168.1.1 does not direct you to the router login page, check with your router support manual for links like “routerlogin.net” etc. In some cases, the information is provided by way of a sticker on the back or bottom side of your router
- There are default values for login in all routers. You need to find the username and password to log into the router; use the following combinations and see which one works for you:
- Username admin; Password password (the characters should be the lower case always)
- Username admin; Password admin
- Username password; Password password
- Username admin; password 1234
- Username admin; password 0000
If none of the above helps you login, reset the router and try again. There will be a reset button on your router. It can also be in a small hole near the power switch of the router.
Insert a pin to access the reset button (in case of a hole). Press the reset button for five to 10 seconds so that the router configuration is set to defaults. Try the above values for username and password after resetting the router.
Caution: Resetting the router will set all values to default. Proceed only if you know how to configure the router.
Where to download the firmware update file
The model number of your router would be printed on the router. It could be printed directly on the router’s body or in the stickers on the backside and bottom side. Make a note of it.
Assuming that your Internet browser is open, go to the website of the router manufacturer. For example, if it is NetGear, type https://www.netgear.com. From there, go to the Support part of the website by clicking the relevant menu tab. In most cases, it is simply named “SUPPORT”.
In the support page of the router, there must be a search bar. Type the router model number and press enter to receive information related to your router. The same page should have a Downloads section. Check out the latest router version and download it to a secure place on your computer.
- ASUS router users visit router.asus.com.
- Linksys router users go here.
- ARRIS router users go here.
- NetGear router users go here.
- TP-Link router users go here.
- D-Link router users go here.
Flashing to update router firmware
Once you have downloaded the firmware update file, go to the browser tab containing router login.
Check for the option that says Upgrade, Admin, or Firmware. It can have another name on the menu, but when you click it, it shows a page asking you to “BROWSE TO FILE” with a text box and a button saying “UPDATE”.
Click on “BROWSE”. When the dialog box to open file comes up, navigate to the place where you saved the updated firmware file, select it, and click on “OPEN” and then on “UPGRADE” button.
It will take some time to update router firmware, depending upon the type of connection between the router and your computer.
Once the update is finished, the router reboots so that you can have a better network experience.
