Wireless networking

I want to set the laptop (win 98SE - yes I know a dino!) for wireless when travelling. I have installed a wireless card, and both lights illuminate when it is within range of a network. The utility software identifies the network, signal strength OK and all that. But when I go into IExplorer it won't connect to anything. I have tried taking all the IP settings out from my eithernet TCP/IP. But still no joy. When I go into IE and type in a page, the lights on the card don't blink, so I think (?????) that IE is still trying to connect through the eithernet card, even though its unplugged from the wall. I've tried typing ipconfig and ipconfig/renew_all into the MSDOS prompt. In both cases it shows to network cards (presumably the eithernet and the Wireless) one with some IP,gateway and DNS settings, the other with zeros thoughout. The one with settings in the eithernet I am guessing. I have removed all the WEP gubbins from the wireless network, and my PDA works fine on it without any hex codes and so on.
Help!!! I am stuck, frustrated and fed up! Absolutely no idea why it may not work. I know some of you are IT fiends - any chance of some tips? Pleeeeease[:X]
