Not connecting to router automatically

I have a new Dell laptop that does not automatically see and connect to my Linksys router. Instead, I see in the lower right hand corner of the Taskbar a blinking yellow dot. When I right click on this a list pops up showing my Linksys and other wifi choices. I have no idea who or what the other choices are, but if I click on Linksys I'm good to go.

Is there a way to default to the Linksys at startup automatically?

Thanks for any ideas.

have you try windows 7 solution center.its an app with flag.try to check internet connections,on the taskbar near the internet symbol.or update your drivers

sorry for the reply.you have windows xp.i thought was w7.but try update drivers

Actually I do have Windows 7. Not sure how that Windows XP appears under my name. I will try that.

Ah, I think that was it.

Thanks for your time.
