I think my IT department was absolutely correct when they said HP notebooks and Linksys adapters don't like each other. The Linksys Wireless G card was slow and the connection very unreliable. At IT's request I bought a Netgear Wireless G adapter. Keep in mind my router is a Linksys Wireless B which works great. The netgear adapter has been up and running for a day now and works great. The connection is strong in places the Linksys would lose the connection at. The throughput is very good. Netgear works with HP notebooks thank God.
Warning: Netgear has a way to go to catch Linksys when it comes to ease of installation and ease of driver upgrades. The Netgear CD puked when it discovered I didn't have netscape on my computer. I manually pointed it to IE which most end users wouldn't know how to do. I had to tweak the settings for 20 minutes before it connected. Again, users shouldn't have to be doing this. Then I went to Netgear's support site to check for driver updates. They list three drivers for this adapter which were basically New, Old and Oldest. Why list outdated drivers? Following their instructions on installing the driver also failed. I finally force fed the newest driver into place. I'm happy this is resolved. Not sure I'd trade in my older Linksys B router for Netgear.
