I assume you are running XP, correct? What's the model of your Intel adapter?
Yes, sorry, XP with SP3. Under hardware I see "Intel 82567LM Gigabit Network Connection" and "Intel WiFi Link 5100 AGN".
Well the upgrade to 126.96.36.199 did not help (didn't hurt either, I had an error when I said I was having trouble reconnecting after the upgrade).
Since you're using 5100 adapter, i recommend that you uninstall the entire SW from your machine, reboot, and upgrade to the latest SW package 13.1.x.x and configure new profiles. Go to Intel Customer Support to find the latest SW package for your adapter. I hope this will solve your profile disappearance issue.
I believe profile disappearance has to do with your OS build. If the issue keeps occurring, then some sort of OS functionality keeps deleting your profiles which you need to figure out. Hope this helps.
Hmmm, it was the intel diag tool that told me the 188.8.131.52 was the latest. I am guess it is in the OS but will see. Thanks.
