I recovery my computer in back few days .
Then I found that my modem had uninstalled so I want to reinstall it .
When I reinstall the modem , the setup came up cannot find any network adapter.
So I went to device manager and found that my device manager don't have a network adapter but came out an 'other device' below it stated Ethernet Controller .
So I guess that was my network adapter and opened it tried to install but without internet I could not install anything ! The computer was bought without disk .
Besides the Ethernet Controller sign , there was also a small yellow triangle inside got a '!' .
Then I check the computer specs and the LAN driver should be REALTEK Ethernet Controller .
I downloaded the driver and transfered it to the desktop and tried to install .
But the InstallShieldWizard told me that 'The Realtek Network Controller was not found . If Deep Sleep Mode is enabled Please Plug the Cable'
What should I do now ? Hope someone can solve the problem for me .
Thank you .
