Massive problems with firmware 386.9 on RT-AC5300 router

Before upgrade save your settings. (your mnt could be different)

nvram show > /mnt/sda1/settings.txt

Restore only the settings from settings.txt that you are absolutely sure off.
For example:

nvram set dhcp_staticlist="values_previously_saved"
nvram commit

Code examples are found somewhere here on the forums. It's not my creativity.

Sorry, disagree. What if the new code's NVRAM has changed that value to dhcp_clientlist? Now you're chewing up extra NVRAM for no reason, and this code needs all the NVRAM space it can get. Or maybe the format of dhcp_staticlist has changed, and you'll just cause problems with the router not interpreting your setting correctly and having problems.

Then you press the Reset button.

Then you press the Reset button.

Then restore your old config

And if not working again - the Reset button! This is the most important button on Asus routers, part of the experience.

Agree that reset and manual config is by far best approach when things go wrong. Generally takes less time than trying to identify and fix issues.

The best use case for setting backup/restore is when you have issue with new firmware, you can flash the previous version and restore settings from a settings backup from this version. Gets you back to where you were very easily. Great for testing new firmware etc with easy way back.

Agree, though wasn't there a case at some point where rolling back to previous firmware didn't undo certain changes to the file system structure? I guess restoring a backup should still work in that case though.
