Acer One 722, booted on batery. The error is shown right away. Still network is accessible. Run yum update - it loaded a few files, then started to fail reporting repos unavailable. Ping checked the gateway - no responce, though network manages still showed wireless connection as available. Package: kernel Architecture: i686 OS Release: Fedora release 18 (Spherical Cow)
