It was thoughtful of you to say which Dell laptop you have. We could have then perhaps helped you.
Without that info, all I can do is guess:
If it's a Latitude C610 (or close), you can try these 3 drivers:
Release Date: 11/6/2002
Version: 1.43, A03
http://support.dell.com/support/down...1&fileid=59417
OR
Release Date: 1/30/2003
Version: 2.50.0043, A11
http://support.dell.com/support/down...1&fileid=63627
OR
Release Date: 3/11/2003
Version: PCHealth Installer, A10, PCTel MDC
http://support.dell.com/support/down...1&fileid=58886
and
PCTel MDC Patch/Updater
Release Date: 2/1/2002
Version: 2.00.61.1, A02PTCH
http://support.dell.com/support/down...1&fileid=43222
And what's up with the weird member name? ie:
pct2304wt. Don't you think that could cause some mass confusion if you posted again asking for a different driver? duh!
