evertime i start up i have to select a network

Everytime I restart my macbook pro I have to go to network preferences and select my network to gain internet access despite having set eveything up already. It is frustrating and I would really appreciate it if anyone could suggest a solution. I am new to MacForum so I hope I posted this in the right place. Thank you

G'day and welcome to the forums.

Well what operating system?

Is Location set to Automatic?

Under Advanced what appears in network name?

is 'Remember Networks Joined' selected?

hi,
running 10.8.4
just checked location set to automatic and now I get the box after starting up that says none of your preferred networks are available and so I select mine then
in advanced what appears under network name is what I named network "namelessbird
remember networks joined is checked

Highlight namelessbird in Network Name under Advanced. if no joy try going into the browser address and setting up agian.
