Profile management features disabled

Hello,

I have a Netgear router and Intel(R) PRO/Wireless LAN2100 3A Mini PCI Adapter. Lately I've been having issues with not having internet access when I'm on my laptop. When I click on the Intel icon I see a message that says that my wireless isn't associated with my profile and that another LAN utility is communicating with my system and so profile management features have been disabled.

Why does this happen? I've checked and the security on my profile seems adequate; why would it cut off my connection if someone else tries to use it instead of not allowing them to use it and protecting me?

Thanks for any help you can give me.
