NETGEAR MA311 - Network adapter - PCI - 802.11b
Easy to install, excellent connection on windows 98 desktop.
Turned off power, took off cover, installed card, replaced cover, booted, pc found new hardware, loaded cd in drive, pointed to it in dialogue, driver was loaded, network was found, connection made, no problem.  I adjusted the antennae and connection is now consistently excellent.  All in about five minutes. <br />Much better than the approx. eight hours I spent on the linksys usb adaptor before I gave up and returned it.
