after using acronis cd recovery my lan did disapear why?

Hi

i used acronis linux iso base to create an image and restore

after i reboot my machine and my lan did disapear , no more internet

i tried to disconnect my router , the light of my lan was green ,working , in the device manager my lan was a ghost in short not preset , like an old hardware removed

i tried many reboot nothing

at the end i had to power off my pc , after that my lan did appear and internet become 100% working

why?
i did check my bios , drivers .. i did not find an answer
maybe could be my lan settings?

thanks

 

I use an Acronis boot CD to do all of my imaging/restores and have never had any LAN issues afterwards. Maybe it was just an odd coincidence?
