view story

http://ubuntuforums.org – O.K. after a few hours messing about I am up and running Lubuntu 13.04. (I have never used anything except Windows for the last 30 years). :) When I first signed in it connected via Wi-Fi to my home network perfectly and I ran the suggested updates. I then moved the PC to it's required location and the Wi Fi reception is poor. I started getting authentication requests asking for passwords and read some stuff about passwords and updating key rings. It said to "sync" the passwords via an option I cannot see in Lubuntu ! Is there some kind of administrator sign in that I can access?? If (Hardware)
