Main wireless network dosen't show up

So right now I'm on a wired desktop computer which gets internet fine, but on my wireless laptop I only get the neighbor's networks (1 bar, secured) and the one at my house I usually use is gone. It's comepletely off the list which makes no sense to me.

Try going to 192.168.0.1, to do that, open firefox/IE, and type that into where you type in internet urls. It should take you to a page (if your router is linksys, it'll be a linksys page. If its netgear, it'll be a netgear page) there double check to see if you set up your wireless.

Make sure you secured it properly, and make sure its on.

d link/netgear routers are 192.168.0.1
linksys routers are 192.180.2.1

those are the defaults anyways.

Seriously? My linksys router is 192.168.0.1 =U...I thought all defaults were the 192.168.0.1 at least thats what I learned in comp networking >_< maybe my teacher was wrong
