The problem in the acer_wmi kernel module. After I blacklist (or just rmmod) this module wireless is starts to work. That also solves two other problems (disabled by default wireless and sound).
So, now I didn't sure: The problem in the 1. acer_wmi kernel module, or in this fact: 2. acer_wmi kernel module starts on unsupported (by this module) hardware. ** Package changed: network-manager (Ubuntu) => linux (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/791373 Title: Can't enable wireless on Acer Aspire 721 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
