LMS upgrade help please

I'm running 7.9xx on Odroid hardware but I'm having to reboot it much too often so I'm overdue for an upgrade I imagine.
The issue is my Radio loses Wi-Fi signal but a Putty reboot sorts it out straight away.
I don't have performance issues so would prefer to keep the Odroid rather than upgrade to Pi if at all possible.
I have a couple of Pis running PiCorePlayer, 1 x Radio, 2 x Classic & 1 x Boom. I use Spotty, BBC & Podcast plugins.

I'm no longer in touch with the technical expert who set the system up for me so I'd really appreciate some help.
I've found a thread that guides me through upgrading from 7.9xx to 8.2xx, but I don't know which version of 8.2xx to download.

Here's my setup as it is now:

Logitech Media Server Version: 7.9.2 - 1543258616 @ Mon Nov 26 20:27:06 CET 2018
Hostname: squeezeplug
Server IP Address: 192.168.1.71
Server HTTP Port Number: 9000
Operating system: Debian - EN - utf8
Platform Architecture: armv7l-linux
Perl Version: 5.14.2 - arm-linux-gnueabihf-thread-multi-64int
Audio::Scan: 0.95
IO::Socket::SSL: 1.76
Database Version: DBD::SQLite 1.34_01 (sqlite 3.7.7.1)
Total Players Recognized: 5

I'm not at all techy but can work my way around USB Image & Putty if I'm advised what needs doing.
Many thanks in advance.
