Networking Breaks After Restoration from Sleep Mode

[M.H.]

I have an IBM TP T42, and when I close it, and then re-open it later, I
cannot reach any websites, and no networked applications functions. The
LAN icon in the system tray does indicate a connection is present, but
there is no functional connectivity. Logging out and back into the
account doesn't work; I have to restart my computer to regain
networking. Why does the machine going into sleep mode break Windows
networking, and how can I fix it? Thanks.

It seems that downloading the "
ThinkPad Power Management driver for Windows Vista, XP, 2000, Me, 98SE -
ThinkPad"
http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-4GXPEG
might have fixed it. Or maybe it was CCleaner
(http://www.ccleaner.com/). I helped out IBM tech support work out a
Sonic RecordNow! issue, and using CCleaner was involved.

If not, open Device Manager, open the properties on your ethernet card
(or USB ports), click the Power tab, and deselect "Allow the computer to
turn off this device to save power".
