Hi,

are you in the BOOTUTIL menu (do you press CTRL-B) ?

If not try to reset to factory default and try again. Save the config first :-).

From which version did you upgrade ?
There where many changes in different firmwares starting from binary file to text file in CLI format.
Changing also in cli commands and denying using of space in descriptions.
I am not sure if i did a cli reboot with the same firmware level but last time it works ...

regards

Hi Markus

Thank you for your tip.
When my router is power on, I am able to stop normal boot process by pressing CTRL-B.
Please be aware that at this stage router's OS and respective configurations have not been loaded yet.
As you know, the menu TP-LINK BOOTUTIL(v1.0.0) can be used to replace or update damaged OS, trough the commands:
ftp - config the remote host ip, the user name,user password and the image file name
and
upgrade - upgrade the firmware

when I run reboot command the switch crashes.
My question is just:
Is this an hardware or software issue?

thanks
