I tried the following command:

sudo apt-get install --reinstall bcmwl-kernel-source

Wireless worked for sometime but after reboot WiFi stopped again.

Can someone please help?

Software center in additional drivers says:

Broadcom Corporation: Wireless 1704802.11n + BT 4.0 This device is using an alternative driver Using Broadcom 802.11 Linux STA wireless driver source from bcmwl-kernel-source (proprietary)

What is the alternative driver? And how to find it?

Also, do help resolve this issue fast.
