I had to downgrade my QNAP to 4.3.4.0675, quite some while ago now, to get it to work on Sooloos. Since then it has run without difficulty. Obviously, disable auto update for the QNAP firmware. All the latest (non Meridian) apps on the QNAP don't seem to mind the older firmware. And if you are anxious about nasties from the internet with the older firmware just get a Bitdefender Box to safeguard your network (including, Bitdefender claim, your IoT devices).
I forgot to add that if you have difficulty finding the firmware I may be able to help you.
Hi
Thanks for the reply.
Yup - auto-update was one of the first settings to check (once I'd restored my backup of settings from the dead QNAP - but backed up before it died).
I have a couple of copies of the 4.2 firmware but I never got around to getting any 4.3 versions as I had no need to upgrade the firmware as it was working. And QNAP do not list any versions of the firmware prior to 4.3.6.0895 that I downloaded (to perform the update).
If you have an older than "x.6.0895" version, (such as x.4.0675) somewhere I'd like to give it a shot....so thanks for the offer. :-)
Nasties from the 'Net" don't scare me...having worked on IP networks (mainly Cisco) for enough years, I have quite a few tools/items of hardware at my disposal to fend off such "attacks".
