After updating the BIOS, this is the output: [ 3] local 192.168.0.3 port 49429 connected with 192.168.0.102 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.1 sec 21.6 MBytes 18.0 Mbits/sec $ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date [sudo] password for [...]: A13 05/18/2013 ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1450755 Title: Intel Wireless-N 2230 4x faster in Windows 7 than 15.04 (iwlwifi) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1450755/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
