7.23.4 upgrade

I am facing many difficulties trying to upgrade. Maybe it is just me, but maybe it helps:

calculating download size lasts forever. It does not do anything further.

same here.

I tried dowloading it and rebooting. It did not work either.

I tried android app as well... Did not work either.

My device is rb4011igs+rm

I am far from being a network guru, but upgrading has been a straightforward procedure until now.

What's your question?

my question is how to ugrade.

Which version are you trying to update from?

7.21.5 according to screenshot.

Hm, you're having issues downloading the packages.

My device storage is full ? How do I check that ?

Maybe this issue: Firmware downloads are slow and often fail
