You'll probably have best results if you disable (either by removing the registry startup key or a setting in the software itself) the software utility that came with the driver and rely on WLAN AutoConfig service built into Windows.
Make sure it is set to auto and running. To do so, type services.msc in the start menu's search box.
TorrentG is absolutely right... just to expand on this; it may be of some ease to disable the startup entry (avoiding risky registry tweaks) by using CCleaner (available at piriform.com or filehippo.com) to disable any startup entry. Should it be unavailable in that menu (which is unlikely,) I'd recommend uninstalling the actual Broadcom software.
Disable and/or remove the wireless driver under your Device Manager. Double-click on "Network Adapters," and when you see the Broadcom, uninstall it.
Now, reboot.
After that, navigate back to Device Manager, and under Network Adapters, you may** see a warning icon (yellow triangle with exclamation.) Right-click on that adapter. Choose to install the driver, but MANUALLY (usually the 2nd of 2 options) locate it.
NOTE: Make sure the Broadcom CD or disk is in your drive.
"Explore" the disk to locate the .inf or .sys file. This is the actual driver. By attaching the actual driver as opposed to running Broadcom's software utilities, you have a much better chance of compatibility, especially with a newer OS like Windows7.
I hope this helps. Good luck; adapter issues are always the most frustrating.
