we tried to use a config backup (from LuCI) of a MT300N-V2 Box and want to use it on an other Box (MT300N-V2). Hardware is the same, firmware, openwrt, kernel all same versions.
If i setup the new box and restore the backup over LuCI, i cant login to GLI UI (ADMIN PANEL) anymore!
If i restore the config on the original hardware, no issue!
But if this Box is defective, i want to use the backup on an other Hardware (same model).
LuCI and SSH is working fine after backup restore, is there a way to reset ONLY the GLI UI password via shell?
The admin hash is based on a salt which could only be generated on the original router. So you cannot back up the hash and use it on a new router. But there is an workaround of this and I will send you via pm.
We too are experiencing the exact same issue. After configuring the first GL-AR300M to our liking, we created a configuration backup through LuCI, expecting to deploy that configuration to the additional GL-AR300M units. As @pseffect described at the top of this thread, we are unable to login to the GL user interface, though we can log into the LuCI interface.
Would you be so kind as to share the workaround with me as well?
Hey Alzhao, I too cannot log into the AR750s UI interface after a restore. Could you please send the workaround to me? I have over 100 routers and do not want to have to manually config each. Thanks!
I have several AR750S. This article and another helped me to create a workaround for the admin password not working, if the backup config is applied to another router of the same model.
Create the backup of the source router.
In the backup file, edit /etc/config/glconfig
Find section: config service ‘general’
Under that section delete lines:
option language ‘EN’
option password ‘blahblahblah’
Save the file and update the archive.
Restore the backup config to the other routers.
Connect to 192.168.8.1 and set the language and admin password. All other settings should be intact
