Hi All,
I am getting a bit desperate after changing almost everything in the ‘equation’ (SD card, wifi dongle, even the Pi2 itself) with no success so far to reconnect to my home server from Volumio and stream music.
I have been using Volumio for years and recently the streaming started to drop and then no sound at all and now - after a couple of reinstall attempts - I cannot even add my music from my server. I am well aware that it can be almost anything but I hope someone may pinpoint that I have not and can finally get back to listening music from Volumio. Strangely enough, I cannot recall changing anything in my setup - neither in Volumio nor in my home server running Ubuntu Linux.
First, I looked at ifconfig output:

Many packet drops on wlan0…
Then, I looked at the dmesg (only pasting the end of it that I think the most important may be here):
[ 39.060830] No dialect specified on mount. Default has changed to a more secure dialect, SMB2.1 or later (e.g. SMB3), from CIFS (SMB1). To use the less secure SMB1 dialect to access old servers which do not support SMB3 (or SMB2.1) specify vers=1.0 on mount.

…and it goes on and on and on. 
Finally, what I can add here is the system journal since boot:
Anyone may have any ideas, please don’t hold it back. I appreciate any help you could provide!
