Some of the issues that can be resolved by firmware downgrade are:
- Incompatibility of software
- Instability of network
- Reduced performance

Users also downgrade firmware because they are used to the useful features, settings, and interface of the old firmware. Few are more convenient using stock firmware than custom firmware and therefore may go for a downgrade.
You may also need to downgrade the firmware of your router if there is an incomplete or bad update or if the beta or experimental version is creating issues.
Sometimes downgrading firmware is necessary if you want to use it as a troubleshooting process.

Always create a backup before you start the process and follow the instructions of the manufacturer. Make sure that you downgrade to a version that is compatible with your router model.
