I have been trying to connect my new Dell XPS 8500 desktop to the Verizon Mifi 4Glte, but with no results. I installed the Mifi software disc program on the new Dell but with no results. So I uninstalled it, since my HP Elitebook 8460p doesn't use the Verizon software. But the Dell still won't connect to the Mifi, even though it shows the Mifi and a good signal coming from it. Any ideas??
