We have tried a few of our networks on 1.4.4 on all of the switches and the network dies, revert the first switch after the fibre to 1.3.9 everything works well
You do realize that after v1.3.9 we added the ability to change under the ports tab the SFP module Speed Duplex?
You now have the option of 1G and Auto.
Prior to v1.4.X you were hard coded to 1G and now the default is Auto I think so when you upgraded to v1.4.X it would use Auto so try setting to 1G or vise versa.
Some SFP modules do not like one or the other setting so try both.
I suggest you try upgrading 1 switch to v1.4.4 and then try changing the SFP module Speed/Duplex
There was nothing else changed between v1.3.9 and v1.4.X that would cause what you're reporting.
If you are not using any SFP modules then I suggest you arrange for our programmer to TeamView into your computer while on the phone and have you demonstrate this so we can fix it for you.
