** Description changed: My Intel wireless card is significantly slower in Ubuntu than it is in - Windows 7. + Windows 7. Turning off Power Management didn't change anything. According to iperf (with the laptop a couple of feet from the router and the server plugged into it): == Ubuntu 15.04 == [ 4] local 192.168.0.102 port 5001 connected with 192.168.0.3 port 43672 [ ID] Interval Transfer Bandwidth [ 4] 0.0-10.1 sec 23.2 MBytes 19.3 Mbits/sec - == Windows 7 === + == Windows 7 == [ 4] local 192.168.0.102 port 5001 connected with 192.168.0.3 port 49247 [ 4] 0.0-10.1 sec 98.4 MBytes 82.0 Mbits/sec Transfer rates for previous Ubuntu releases are about the same: - -- 13.10: [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.1 sec 22.6 MBytes 18.9 Mbits/sec -- 14.10 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.1 sec 27.8 MBytes 23.1 Mbits/sec - I have attached the output of Wireless Script, which should give all the - necessary details about my setup.
