I have some problems with WiFi on Ubuntu 14.04. My ISP provides me 40Mbps internet but in Ubuntu I can only receive 20Mbps. Same problem I had with OpenSuse distro. On my Windows 7 that problem doesn’t exist, it receives full 40Mbps. Please note that I am not running Virtual Machine, I use dual boot (Ubuntu/Windows 7). Informations about my Wifi card:
03:00.0 Network controller [0280]: Qualcomm Atheros AR9462 Wireless Network Adapter [168c:0034] (rev 01)
Any help or suggestion?

driver, so you may want to try a newer kernel. See askubuntu.com/a/598934/175814 for instructions.
