Will not automatically connect to preferred Wireless

I've used my wireless router for quite some time, but I recently got a new
computer. Therefore, I'm sure that's where the problem enlies. I set up
preferred wireless connections for school and home. Whenever I'm at school,
the internet connects automatically, but at home it wil not connect. In fact
when I look at my available wireless connections, I see "Unnamed network"
Secured. This is my network because it's in high signal strength and I can
connect to it. The problem is everytime I need to connect, I have to type in
the name for the network and the key. It has detected my network the first
time I set it up with the name and did it automatically, but it doesn't
include the name or connect automatically any more. I did check the boxes to
save and connect automatically, so it's not like I have those off. I'm sure
this is something simple, so if you could shine some light on it I'd
appreciate it! Thanks in advance!
