How to upgrade the firmware of a Tenda router? Online upgrades are done with one click; if the new version can't be detected, I use the official website local route

my mother-in-law's Tenda AC10 has been disconnecting frequently in the middle of the night lately. Restarting once takes three days. I remotely glanced at the runtime and recalled the wall I encountered when enabling IPv6 ( mentioned in Tenda's IPv6 article that old firmware didn't have that switch), so I suspected the firmware was too old and went through the upgrade process from start to finish. Tenda's firmware upgrades are completely different from Mercury's. Here's the conclusion: Tenda's backend comes with built-in online upgrades, so you can upgrade with one click as long as you can connect to the internet. Most machines don't even need to go to the official website for .

Before

get started, copy two things: model and hardware version

don't mind this step being tedious—when it comes to firmware, recognizing hardware version is even stricter than just identifying the model. The same AC10, V1, and V6.0 firmware look like twins; if flashed incorrectly, it can cause a misfit and fail to install, or at worst, the machine can become bricked. I know a guy who brought his Mercury Bin bag to feed Tengda, and the backstage was very generous and refused outright—but if you're lucky enough to get something that can be written, that's a lot of fun.

these two pieces of information are viewed in two different places:

First, the bottom sticker the router. Flipping it over, the model and hardware versions were clearly stated. On the AC10 sticker, the hardware version section shows "V6.0," which is exactly what you want to aim for.

Second, the backend to report yourself. Enter tendawifi.com in your browser (if you can't open it, enter 192.168.0.1, both are the same door), log in to the backend—if you forgot your password, first check the rules for Tengda's initial password the homepage or 'System Status' page shows the current software version, with a string of 'V16.03.xx.xx.xx.' "Numbers that look like these." Take a screenshot of this page with your phone, then come back after upgrading to check and confirm that the version number really changed.

Route 1: Online Upgrades—Connected to the Internet, One-Click

this is Tenda's most convenient feature, and also its biggest difference from Mercury—Mercury officially states that the entire series does not support automatic upgrades (my D191G was manually downloaded from the official website, and the process is described in the of the Mercury firmware upgrade article), while Tengda, on the other hand, is connected directly to the cloud.

path: Log in to the backend and go System Management → Device Management → Software Upgrade (some new interfaces are "More Features → System Management → Software Upgrades," with menu names in similar locations). The top half of the page is 'Online Upgrade.' Click 'Check' and it will download new versions by itself. The whole process takes two to three minutes, and you just need to watch.

three prerequisites to keep in mind

• router must be able to access the internet. When the network is offline, the detection keeps spinning, not because it's broken. First, restore the network before trying again.
• upgrade, if FamilyMart disconnects for two or three minutes, the vacuum camera will disconnect and reconnect. Pick a time when no one is playing or video calling.
• don't unplug the battery the whole time. If the upgrade loses power halfway through writing, the machine is likely to brick—this is a common rule across all brands.

mobile app can also upgrade . After binding the Tenda WiFi app to the router (if binding fails check the troubleshooting in this article), find firmware upgrades in the tools. One-click on your phone, perfect for watching TV on the sofa. App upgrades also follow the same cloud package, no different from the web backend.

online says it's "already the latest," but the official website reveals the new version

this is the pitfall I've fallen into. The AC10 was upgraded online, and the page replied, "This is currently the latest version." But I clearly remember the official website has its new firmware—go to Tenda's official service support → download center , search for AC10, and the V6.0 firmware package is there, with the release date more than one version running on the machine.

later figured it out: online upgrade detection relies on cloud push records, and the official download center is not the same . If the manufacturer launches in batches, old models are discontinued, or your firmware version is too old to appear on the push list, there will be a mismatch of "online saying it's not available, but the official website actually has it." So if the online upgrade prompts that there is no new version, don't rush to close the page—go to the download center to get the model and re-check. This step only takes one minute.

download center: searching for "AC10" shows that the firmware package title includes a hardware version number, for example, "AC10 V6.0 Upgrade Software V16.03.xx." Aim at the V-number copied on your sticker and click download. Don't be fooled by the new version—if your V1 machine has a V6.0 package, you'll feel embarrassed to blame others when you extract it.

Six Steps to Local Upgrade, the bin file is the main focus

the official website is the compressed package; local upgrade manually feeds this package to the router. Six steps in total:

extracted package usually comes with an upgrade guide. The official recommendation is to follow it—it's a minute's worth scanning. From my actual experience, upgrading from the old AC10 version to V16.03.34 took less than three minutes, which was similar to the Mercury official download plus manual upload process. The advantage is that Tenda's online upgrade covers 90% of scenarios, and the local route is reserved for the remaining 10%.

After upgrading, do three checks first; don't rush to close the page

after rebooting and logging into the backend, don't think everything is fine yet—spend two minutes checking the accounts:

check the version number . Go back to the software upgrade page and check if the software version has changed to the account you just upgraded. If it matches, it means the package really went in, not just failed to upgrade and bounced back.

Second, check WiFi and internet . Just connect your phone to WiFi and casually open a webpage. Normal upgrades won't change configurations; broadband account and WiFi password should remain in their original locations. If you encounter the unfortunate situation where your configuration gets cleared (which happens occasionally during local upgrades), just follow the path the phone WiFi password reset and refill your broadband account. So it's a good habit to copy your broadband account password before upgrading. I'll write about this in the article on router configuration backup

third, check special configuration . Advanced settings like port forwarding, IPTV VLAN, and static IP binding—open each one to see if they're still there. Firmware upgrades across major versions occasionally reset certain advanced options; those who don't need these features can skip this option directly.

What kind of machine do I advise you not to mess with

not every Tenda is worth upgrading. I've categorized the machines around me:

use it well, don't chase after new . Firmware upgrades are not health supplements; a stable machine runs without faults, security announcements, or essential new features (like IPv6 switches not available in old firmware), so just let it run. When it comes to firmware, "latest" and "most suitable" are often not the same. I wrote about the general principle in the whether to enable automatic firmware upgrades.

an old machine that has stopped updating from the official side, upgrading won't save . I also have an old AC series from 2016 at home. The latest update in the download center was a few years ago. Disconnections and lag on this kind of machine are due to old hardware, firmware upgrades are psychological comfort, not a symptomatic fix. When it comes to rebooting every few days, switching to a new one is more effective than any firmware.

has already bricked, the self-rescue order is : first turn off the power and wait one minute before powering on, then check if the indicator light works properly; If that doesn't work, press and hold Reset to restore the factory (the configuration will disappear, which is why I asked you to copy the broadband account earlier); If not, contact Tengda after-sales service. The official customer service phone to report the model, and if it's not caused by human factors during the warranty period, you can replace it. Beginners should avoid brick-saving packs on third-party forums; I've seen more than one case of bricking on top of brick.

Here's the order to wrap up: copy the model and hardware version→ Click online upgrade, click → If there's no new version, check the download center for a quick look. → If it is, extract it and follow the local six steps. → After upgrading, check the three checks → old and stable machines. Just close this article. Tenda's upgrade experience is quite worry-free among home routers; just don't be intimidated by the word "firmware."
