Are you able to connect to other networks? Starbucks or anything else?
You can go to support.dell.com and download drivers from there make sure you use the Dell service tag (bottom of laptop)http://support.dell.com/support/downloads/...p;fileid=233125
Try going to Start-settings-network connections- Advanced- Advanced setting - move Wireless Network connection to the top.
There might be a conflict between two programs trying to control the same Wireless card. Windows has its own and depending if the driver that was installed also installed a program to run the wireless card.
You can then go to Start-settings-control Panel- Add/Remove Program and find the driver software there uninstall- Modify- uninstall everything but the driver( the first in the list)
