I have an HP-Envy-4 laptop(dual boot Ubuntu 13.04 and Windows 8) with a BCM4313 Wireless card. The strength not great when close to the router. However, the WiFi works well on Windows 8. I tried installing the Broadcom STA Wireless driver but resulted in Wicd not detecting my WiFi connection. What could be the issue and how can I resolve it? Any help would be appreciated. Thanks!
Here is some additional information:
