about the problem being a result of your installation of the WPN31,1as the problem lies within the configuration utility for the wireless adapter.
You could uninstall the NetGear config Utility and just use the Native Windows utility for your wireless or you could contact NetGear Support and see if they have a fix for you.
When I startup my Dell Optiplex 745 (Wind. XP Prof. SP3),
on the dsktp screen, a window pops up w/the heading: "wlancfg5.exe - Entry Point Not Found". Undernth that it reads: "The procedure entry point ?AcsWsNotifyProfileChange@@YAHJPBD@Z could not be located in Dynamic Link Library athofg11.dll." After pressing "OK", the system does let me continue, but I wondered what it was about? As I recall, the window started popping up, after I had installed the software/hardware for the NETGEAR WPN311 Wireless PCI card, which by the way, has also been uninstalled. Any ideas? Thank you in advance.
