now again I connected without router.
Core--Core
I can download single Zip files of 300MB + ( earlier I have not tried single compressed files ), both ways multiple times. If same file is extracted & try to download then it stops after some time. Folder contains, exe, doc, etc.
Other B end don't respond, again we need to access via Ssh & reboot the machine
Core-Edge ( above issue )

Edge--Edge
No issues oberved even for extracted files, I was able to download 600Mb extracted files muliple times both ways.
Do you think I should try with 1.2.1 version
