Do You Factory Reset After Firmware Updates?

[kc27]

I had read or someone told me once that a firmware update should be followed with a factory reset. The reason stated was that menus or options could have changed with the new firmware. To ensure the router settings matched what they were prior to the firmware update, it was best to re-enter router settings from scratch. Is this a best practice, or someone going over the top and making more work for themselves?

If you want an official statement:

"Notice: It is recommended to restore to factory default settings by pressing the reset button on the bottom of the wireless router for 5 seconds after doing a firmware update. After the reset is complete, please go to http://www.asusrouter.com and follow the QIS to set up your router again."

This FAQ page was last updated on 2024/08/30. Here you have it - from the manufacturer. Most people don't do it, only if issues are encountered after the update. If you call Asus Support for whatever reason though - reset to factory defaults is the first thing they are going to ask you to do.

It probably depends on which make and model of router you're using as well as which firmware version you're going from and to.

As you've posted this question in the "General Wi-Fi Discussion" section there's no definitive answer other than to read the release notes and see what it recommends.

Thanks. I had never done the factory reset after a firmware update, either.

This week the router could not connect to the modem. A factory reset was what fixed it I also saw a firmware update was made available a few weeks ago (surprised because this is an rt-ac88u that was introduced in 2015). I did save a configuration to expedite router setup.

I like the router, but plan on replacing it.

Normally no.

However, I sometimes switch firmware for testing or I make so many changes testing things I want a clean slate then I do a reset with initialize. I often have a basic settings file for each firmware version which allows me to get the router back up in a matter of minutes. I've done a setup so often that I can fully set up the router with mesh in about 20 minutes or less...

Good to know. Not exactly the same as what you are doing, but I was planning on importing all my saved settings vs entering them from scratch.

If you are talking about your RT-AC88U - this router is on End-of-Life list and you don't have to do the manual configuration many times. The current stock Asuswrt firmware for it is perhaps the last one and RMerlin announced discontinuing of 386 base Asuswrt-Merlin support after the end of 2024. If you are planning to use your RT-AC88U settings on a new router - set the new router manually from scratch. This is the best practice.
