Re: wireless is slow to connect at startup
One thing that may help is to right-click the NetworkManager icon, select Edit Connections/Wirelss, select your network from the list, then click on edit. You may be prompted for a password. In the dialog box that then appears, near the bottom, check the box for "Available to All Users". This will enable connection to the network before the Desktop loads.
If you don't see your network listed, you may have to make your ESSID visible in your router settings.
There are no dumb questions, just dumb answers.
