The first three results are on Windows 7, second three are on Ubuntu 15.10. Same laptop in the same place. Kernel version is 4.2.0-25-generic I can install the mainline kernel again to try to help. You asked whether switching 802.11 type made any difference on the mainline kernel - what is the easiest way to switch between these 802.11 types? -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
