College Dorm Network Issues

Hey guys, I have 2 questions/problems I need solved and I can't figure them out. Here goes:
Question 1: My laptop died at work today due to the battery, it went into hibernate. Upon waking it back up once I got home to plug it in, upon doing so it connected to the wireless router in the room, but could/would not load up any web pages. What gives? There is activity on the wireless signal, albeit a small amount, but its showing very good service with movement both in and out.
Other Pertinent information: Wireless card is on, running ZAP, XP Home
Question 2: I have a desktop in my dorm connected via wire to the school network. I have the ability to run that wireless as well, I choose not to because I don't need to. I would like to print things on my laptop, however, without having to move the cable back and forth. Upon switching to wireless on the desktop, I am unable to "network" both my desktop and laptop together to share the printer. How can I go about doing this?
Other Pertinent Information about desktop: running ZA, XP Pro
Thanks in advance for taking the time to read guys! I really appreciate it.

Problem has not gone away in question 1.
You can do this check by clicking:
Start Menu -> Run -> Type "CMD" -> Type "ipconfig"
What information does it return..?
Guess I should have mentioned that. Yes, it has given me one. I just don't understand why it works on the school's public wireless and my office's public wireless.
Didn't post what it returns, but it gives me an IP, a gateway, and a mask. None are out of the ordinary, starts 192.xxx.xxx as it should.
