I have the same problem.... Dell Inspiron 1525 with a Broadcom BCM4312 wireless card 802.11b/g, used in conjunction with the STA wireless driver on a Linksys WRT160N wireless N router that's broadcasting both G and N wireless. Wireless connection works completely fine, which the applet confirms on mouse over, but it still shows an exclamation mark. I recall that on install there were two possible drivers, but after installing the STA driver I can only access that one in the restricted hardware manager.
