Fail to connect the internet.

Hi,

I have a dell laptop with win xp pro.
The driver is intel(R)Wireless 3945ABG Network Connection.
I cannot connect wireless network because it always showing not connection even I enable it etc.

The strange thing is that:
I am living in the university apartment. The are internet port on the wall. Just pluging the cable in then network connection works. Each time the the first screen is the specific login interface when the IE is launched. It means it is forced to redirect to this page.

If I bring the laptop to other places such as my company. Both Lan or wireless connection fail. In this case, wireless network doesn't show connection. Although lan connetion shows ok but it can not really reach thw web site.


Thanks.
