Hi everyone.


I'm trying to upgrade the firmware of the router (TL-WR741ND), but there is the following message


The device cannot perform software upgrades via the remote management tool. Please upgrade software from within the LAN.


The buttons "Select file" and "Upgrade" both are disabled.


I'm trying to do this process from the LAN network, as the message above says to do.


Does anyone know how to solve this?
I really need to update this router.

Thanks in advance
