Public bug reported: I've got this WiFi card: 02:00.0 Network controller [0280]: Intel Corporation Centrino Wireless-N 1030 [Rainbow Peak] [8086:008a] (rev 34) Subsystem: Intel Corporation Centrino Wireless-N 1030 BGN [8086:5325] Kernel driver in use: iwlwifi Under Ubuntu 14.04 it only goes as high as 150Mbps. Under Windows same card goes all the way to 300Mbps DL speed. Please note that the card is 1x2. e.g. 150Mbps Up and 300Mbps Down. Maybe that causes the problem. after iwconfig wlan rate 300M it fell to 1Mbps and stays there even after switching it back to auto sudo iwconfig wlan0 rate auto
