I encountered a severe problem after buying a Windows 8 machine : connection with mybookworld was sytematically lost after a few seconds using NAS mapped or not mapped + accessing files (read or write).
My Windows XP computer didn’t make such a problem.
I’ve found few help reading the forums, but no reported simple solution and explanation…
After 2 weeks of problems, I think I’'ve solved it !
My solution was to disable WIFI from my BOX/router. Althought my NAS wasn’t WIFI, the association Windows 8 (64 bits) + Box Modem ADLS/Router (Freebox) + MyBookWorld made this problem happen.
In forums I read about a problem of MTU but I can’t set them neither on the box, nor on the NAS :
Hope this helps someone and perhaps anybody could give us a nice technical explanation !
