When I am using the wireless on my dell laptop, the internet crashes and reconnects every few seconds or minutes. I looked at the error files on my pc and it is called an "application hang." the general description tells me that internet explorer quit working with windows. Any clues on how I fix this?

Uninstall and reinstall Wireless Network driver from Dell's site. Other things you could try:

1.  perform a clean boot.

2. Reset

Thanks, S.Sengupta! The IE Reset worked and IE is not crashing anymore. Is there anything I can do or avoid to prevent this from happening again? I would hate for it to happen while I'm in the middle of a financial transaction. 

Thanks again!
