My Lan port on studio XPS 13 running windows vista has a funny problem,

My lan port will not work after the system resumes from sleep.

It will show as disconncted, even the lights also will not go

This condition will remain untill i restart my system.

I have have all possible things

But nothing is helping in problem resolution

Also if i put my system to Hibernate and when i come back the LAN will show a yellow mark and will not work, but if i disable and enable, it starts working

This is not the case though in sleep mode

Please help
