I don't have much experience with the RPI and I don't know many
commands.
This in fact is the reason why I asked for help here to understand how
to solve the problems described in my previous posts .....
Regarding the 'grep' command I had never used it (I had seen that it
allowed to find strings inside files) and I trusted myself to use the
syntax suggested to me, assuming it was the right one ....
After your posts I saw the error!
However, my syntax errors in some commands (for now only with 'grep'!)
I don't think they can be related to the problems described in my
previous posts!
I refer of course to the download speed zero Mbit/s of speedtest-cli
and to the errors 404 with the command 'sudo apt-get update' of my RPI3
installed at 500 Km from where I live normally.
Thanks anyway to all those who tried to help me.

Returning to technical problems: as soon as I go to the remote site, I
would try to move the RPI3 LAN cable to a 100 Mbps mini switch because
it is now connected to a TL-SG1008PE Gigabit PoE switch and one of the
things I did not understand is why the RPI3 which has a 100 Base
Ethernet port with the command 'sudo mii-tool' shows 'eth0: negotiated
1000baseT-HD flow-control, link ok'
