|"tried different solutions.. but none of them work"|
Well to save us wasting time suggesting things you've already tried why don't you just tell us what they were.
Such as: Tried to do a system restore
Tried deleting the device in devicemanager and re-starting to reinstall the network adaptors.
Tried updating drivers.
Done virus scans etc.
What if any results or error messages did you get?
