Windows 7 does not reconnect to wireless network for exactly one minute after resuming from sleep mode.

It takes my computer exactly one minute to connect to a wireless network, any network, after coming out of sleep mode.  The networks are visible immediately upon resume, but it just won’t connect until a minute has passed.  Interestingly, it doesn’t have this delay when rebooting or on resuming after going into sleep mode the first time following a reboot.  

I’m running Windows 7 Professional with an Intel Centrino Advanced-N 6200 AGN adapter.  All drivers and firmware are up to date and power-saving management regarding the network adapter is disabled.

I thought it sounded suspiciously like the Windows broadcast flag was causing the problem because Windows tries for exactly one minute to acquire an address in DHCP DISCOVER mode with the toggle set to 0, then switches the toggle mode to 1 and tries again.  However, when I reversed the default mode by changing the registry value of DhcpConnForceBroadcastFlag from 0 to 1, it made no difference.  Perhaps there's more to the broadcast flag behavior than I understand.
 
What should I try next?
