To enable SSH it is as simple as restoring a pre-made config.
From stock firmware you restore this config and you have SSH login.
This is from my notes:
- A premade backup config file, enabling SSH, can be found at Dynalink DL-WRX36 Askey RT5010W IPQ8072A technical discussion - #670 by NicholasKK
Restore with this config, wait for the reboot, and login using SSH, as admin / askey1234.
