I tried updating the firmware of my router manually (via router UI), however, all the files in the provided attachment resulted in an error (see sample screenshot).

Upgrade operation failed?

There is no suitable file to use for the upgrade itself. Can you tell me which file extension ahould be used for the firmware upgrade?

Which file extension should be used to upgrade the firmware?
