Limited access at home and school

I've been using my HP Laptop at school and home for the past couple weeks without any problems, but today, when I tried to connect to the university wireless network, I could only connect with limited access. All the available networks shows up, but I could only get limited access. Later, I got home, and I plugged in my wired internet (goes into a wired router), but I had the same problem (limited access), except that it was not even recognizing my Home network, like it usually does. Instead, it only recognizes an Unidentified Network.

Also, earlier in the day, when starting up the laptop, there was an error message (right after the OS loaded) saying that logging on went wrong, and I had to force restart. Don't know if that may be related.

Any help would be much appreciated.

Check to make sure you have automatically obtain IP address turned on. Limited connectivity is usually an ip address problem. Have you disabled any services lately? If so enable them and restart. Let me know if this helps.
