Coming back to the update aspect, one additional thought (I still did not manage to download the new release due to poor network coverage at the airport
and I do not want to take the PAW out frequently neither do I have a second Pi):
Assuming that the download and update process works in a way that the update-procedure first downloads the update file into a specific folder in the filesystem and that afterwards the software checks whether there is a file and if so starts the update, wouldn't it be possible to manually put the file into that folder and then click "update"?
Downloading at home, taking a notebook to the airport, putting the file into the respective folder using the notebook and then let the PAW do the update would work well for me...
Should that work, could you please indicate which folder in the filesystem to use?
