The IBM Thinkpad iSeries is not equipped with a built-in wireless capability. However, I have previously used an external USB wireless adapter to successfully access the Web. This may prompt a question on your part: So, why not just continue to use the USB adapter? Answer: A PCMCIA card is the closest thing to "built-in." No external adapter dangling from a cable. And use of a PCMCIA card would free up the single USB port with which this laptop is equipped.
If I understand what you have told me, all I need to do now is delete the previous installation attempt, then just plug in the Lynksys card, boot up my laptop and let W2K do the rest?
