A problem developed with my daughter's internet connection and the Wireless router adapter. Her adapter could no longer make a connection with the internet and the computer would not allow me to create a connection. While trying to resolve the issue with the Linksys tech, it was discovered that when I open the Device Manager, it is completely blank -- nothing is listed and I cannot navigate around the panel either. The tech told me he could not help me further until I could get this issue resolved. I cannot figure out what has happened. I don't know what to do or how I should proceed. Please help me! Thank you.
