I can't find the paperwork for my password for my router, but have it saved under preferred networks. I was reading forums about how you could easily go into settings and "edit" the network, then click "show password" and the password would be there. My problem: I click edit and my password (shown in dots) is grey along with the "show password" box. If I click in the password box the saved password disappears. How do I get my "show password" box able to be checked?
