How to Roll Back a Router Firmware Update

When rolling back makes sense

A firmware update can change how a router behaves. Sometimes a new release fixes one problem and creates another: Wi-Fi disconnects, slower throughput, a feature stops working, or the admin interface becomes harder to use. If the problem started right after an update and a reboot does not help, downgrading to the previous version is worth trying. Before you act, read about router firmware updates to understand how the update process works.

Rolling back is not the first step. Reboot the router, reset the modem or ONT, and test on a wired connection. If the trouble continues only on Wi-Fi, the issue may be a setting rather than firmware. If a factory reset also does not help, a downgrade is a reasonable next option. For failures that happen during an update, see router firmware update failed before trying to restore an older build.

• Wi-Fi dropouts or weak coverage that started after the update
• Wired performance that is much worse than before
• Features missing or changed in a way that breaks your setup
• The router becomes unstable or resets by itself

Back up settings and check the current version

Before you install anything, record the router's current model and current firmware version. The model and version are usually shown on the router label or in the admin page. Back up the configuration if the router offers that option, so you can restore your network name, password, and other settings after the downgrade. The process is described in how to back up and restore router settings.

Also note why you are downgrading. If the new firmware was released to fix a security problem, going back to an older version can expose the network. Wi-Fi Alliance explains that WPA3 networks use the latest security protocols, disallow outdated legacy protocols, and require Protected Management Frames. Older firmware may lack those protections. Review router security basics and WPA3 explained before you decide.

Find an official firmware file

Router makers do not always publish every older firmware version. Start on the maker's support page and look for a download, firmware, or support section. Search for your exact model number and see whether the maker lists previous releases or only the newest one. If only the current version is available, the maker may not support downgrades, and installing files from other sites is risky.

Some routers include recovery mode separate from the normal update page. Recovery mode is meant for restoring a router after a failed update, but it can also accept an older official firmware file in some cases. The exact steps depend on the model. For routers that become unresponsive, read bricked router recovery.

Restore the previous version

Use a computer connected by Ethernet when you roll back firmware. A wireless connection can drop while the router reboots, which may interrupt the update. Open the router admin page, find the firmware update or administration section, and choose the file you downloaded. If the page refuses the older file because it is older than the installed version, check the maker's support instructions to see whether a special recovery procedure is required. You can review the steps for getting into the admin area in how to log in to the router admin page.

Do not close the browser, unplug the router, or reboot it while the file is being written. The router may appear to restart several times. Wait until the admin page returns or the status light shows a normal state. A full guide to the normal update flow is in how to update router firmware, and it is the same care you should use when rolling back.

Check the router after the downgrade

After the router restarts, sign in, restore your saved settings, and verify that the firmware version shown in the admin page is the one you intended. Reconnect your devices and test wired and wireless performance. If the problem that triggered the downgrade is gone, keep the router on that version for a while, but check occasionally for a newer release that fixes the issue.

Downgrading is a temporary fix, not a permanent answer. An older firmware release may lack bug fixes or security improvements. If the current version remains unstable, consider whether the router is nearing the end of useful support. See router support life expectancy and when to upgrade router to judge whether a replacement is the better long-term move.

Keep security in mind after rolling back

Security should influence your decision. NIST develops cybersecurity standards, guidelines, and best practices that organizations and individuals can use to manage risk. A router running old firmware is harder to protect if that firmware no longer receives coordinated security updates. If you must stay on an older version, run the latest Wi-Fi security your router and devices support, use a strong admin password, and disable remote management when you do not need it.

Wi-Fi security has improved over generations. Wi-Fi Alliance notes that WPA3 provides more robust authentication and protection from password guessing attempts, while Protected Management Frames help protect management frames. If the older firmware does not support WPA3, you might need to accept a lower security mode or plan a router upgrade.

What to pick for your use

Questions

Can I downgrade router firmware to any older version?

Usually not. Most routers only accept firmware files made for the exact model, and makers often limit how far back you can go. Check the maker's support page for a list of available versions.

Will rolling back router firmware erase my settings?

Often yes. The router may return to factory defaults during the process. Back up your current settings before you start, and plan to reconfigure after the restore.

Is it safe to use firmware from third-party sites?

No. Use only the router maker's official support files. Unofficial files can be incomplete, modified, or made for the wrong hardware and can leave the router unusable.

What should I do if the older firmware will not install?

Check the maker's recovery procedure for your exact model. Some routers need a special recovery mode, and some do not allow downgrades at all. If recovery fails, see bricked router recovery.

Does rolling back make my router less secure?

It can. A newer release may include fixes for vulnerabilities, and older firmware may not support current Wi-Fi security features. Weigh the stability problem against the security risk before you downgrade.
