After I restart my laptop I am not able to connect to my wifi network automatically. The AE status bars are grayed out and I have to click on them and select my network. I thought I configured everything properly. From System Preferences I went to Network (Location is set to Automatic and Show is set to Airport. I then went to By default, join and selected Preferred Networks. I then added my network to the field. Is there anything else that I should be doing? Thanks.
