MY OS is Windows 10 that I use to upgrade Dlink products in mydlink. I used mydlink on LinuxMint in the past until they changed java crap etc . I have had the same problem upgrading to version 2.02 firmware too on Windows 10 , tried everything from Mydlink install and manual install same results . When I did the update to 2.02 it kept on rebooting over and over I could log into it when the blue light was on by IP address but it starts to reboot before I could do anything . So I ended up pushing reset button to bring back original version after being fed up. It would take version 2.00.1 firmware but not version 2.02 ,weird. The upgrade 2.02 ruined the other DNR 202L It would not reset at all or take manual update to 2.00.1 I was lucky the store replaced it for me . So far I hope there will be a bug fix coming soon as I can not use the DNR on mydlink web site only thru IP address .
