the manual says that I could upgrade my firmware from the current version "65.51.61" via the web interface ("System" -> "Software Update" -> ). However, there is no option to select a firmware file to upload, as stated in the manual, only a "button" where I can activate or de-activate updates. I cannot choose a file manually.
Using the Windows/Mac Programmes is not an option, because we use Linux exclusively here.
There IS a new version available ("65.51.71"), which seems unimportant as of now, because the changes described in the "readme" file seem to be irrelevant fo me, but this can change soon; so I'd like to resolve this issue now.
