Broadcom BCM4313 802.11bgn Wireless Network Adapter Wireless
First of all, some of the original drivers of that modem are not compatible to GNU-LINUX libre programs.
The close drivers are proprietary, but the other Open drivers are under the GPL license, for everyone to download and study. but those GPL drivers will sometime, disable some of the functionality of the modem itself. Because the firmware demand the proprietary drivers own by the manufactures.
When I encounter issues like this, the first step is, What are the GPL firmwares supporting this product? I'll be polite to you, but you need to do your homework first AND RESEARCH THEIR WEB SITE for the GPL drivers THEY ARE USING! and take it from there. Wrong web site to teach others How to flash firmwares.
Why don't you buy a compatible Mini WIFI card from Think Penguin? I had purchased 1 mini PCI for my laptop and still working without issues so far.
