Somehow, some way, I got it to work. I have no clue as to what did the trick, but all is well, now.
I'm sure it had something to do with ndiswrapper. One change I did make was to rename the driver files. They were originally in uppercase, so I renamed them in lowercase. I don't know if that makes any difference or not in Linux.
The other major change I made was to the security of my wireless router. It had been set to 64-bit security, rather than 128-bit. I'm now using 128-bit WEP, ASCII.
Thank you for your help, nyjetshead.
