I recently downloaded the new OS X Lion for my iMac and have had some odd problems with it.

First, when I start up my computer it now asks me for a password (never had to do that before) and if I put my password in, the computer loads and tells me I have no wireless programs installed. However, if I click the restart button when the computer prompts for the password all programs work fine and I have my wireless programs. How do I get rid of the password glitch on start up?

Second, when the computer goes to screen saver it drops the Internet connection. When I wake the computer, I have to then reconnect and select my Internet network. Why does this happen? I have looked in my preferences and there is no selection to change this.

I have un-installed and reinstalled the OS X Lion program, but it did not help with any problem stated above. Any help would be greatly appreciated.

Thank you
