[saurav25]

Hi Guyz,

I dont know where to post this....but i am having a very big problem with my wireless adapter.

suddenly during working my connection got lost...i am able to connect thru ethernet.
In device manager..my device manager is showing an excalamation mark over the network adapter with error code as 'Device can not be started'
when i am uninstalling and resinstlaling the driver two drivers are coming
Intel pro wireless 39454BAG and Intel pro wireless 39454BAG-Miniport work scheduler..The second one when double clicked showing fine.
but the first onw is getting installed everytime.
Please help
