The Broadcom Limited BCM43142 802.11b/g/n wifi card is not a Dual-Band card. That is, it only operates on the 2.4GHz band of wifi network technologies, even though the system says it can support 5Ghz frequencies.
If you have confirmed 5GHz networks are in your area, but still cant' see the networks, then the card is not able to support 5Ghz and the card is falsely reporting 5GHz support.
You would need a Dual Band wifi card in your computer to be able to use 5Ghz connections. (The 'n' designation of wifi standard on the card doesn't indicate that you have 5GHz capabilities)

@sam I already looked up the specific card you indicated. HP models had this card in them, and their own forum indicates it's a single-band card (see h30434.www3.hp.com/t5/Notebook-Wireless-and-Networking/… where they say "That is a hardware issue. You can't turn a 2.4 GHz card into a 5.0 GHz card with a driver update." which indicates the card is a 2.4GHz only card)
