I've been having trouble with the embedded wireless card in my laptop. I run Ubuntu Hoary and here are the laptop specs:
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Inspiron 9300 Intel® Pentium® M Processor 730 (1.60 GHz/2MB Cache/533MHz FSB)
Display 17 inch UltraSharp Wide Screen XGA+ Display 17XGA
Memory 512MB Dual Channel DDR2 SDRAM at 533MHz 2 Dimm
Video Card 256MB NVIDA® GeForce Go 6800
Hard Drive 100GB Hard Drive
Network Card Integrated 10/100 Network Card and Modem
CD/DVD Drives 8X Max DVD ROM Drive
Wireless Networking Card Intel® PRO/Wireless 2200 Internal Wireless (802.11 b/g, 54Mbps)

I've gotten this card to work before (although not very well) on my father's wireless network (which used a LinkSys router). Now I'm trying to use the network at UT and I set everything up properly (and checked it twice), and I get 0 signal strength. I borrowed a Linksys Orinoco Gold 802.11b PCMCIA from my labmate and everything works perfectly.
I have no idea what's up with this. Does the embedded Intel wireless just suck or not have good Linux drivers for it? Here's the output of ifconfig and iwconfig when I'm connected with the PCMCIA card. (eth0 = wired network, eth1 = intel embedded wireless, eth2= PCMCIA wireless)
ifconfig

Does anyone know what could be wrong here?
