Unfortunately, they have decided to attach the auxilary antenna in the factory and not the main antenna. Udev sounds like the right place to quirk for this. Presently we're using an upstart job, the text of which is : # LenovoBx70eAtherosAntenna.conf # # Lenovo B[45]70e systems with Atheros AR9285 wifi only have one # antenna, but the ath9k driver defaults to using two antennas (Main # for Tx, Aux for Rx). This job reconfigures the driver to use the # main antenna for both Tx and Rx before networking starts. description "Fix antenna configuration for Atheros wifi on b470e/b570e" start on starting networking task script # only required for Lenovo B470e and B570e dmidecode --string system-version | grep --quiet --line-regex "Lenovo B[45]70e" || exit 0 # only required for Atheros AR9285 devices lspci -n | grep --quiet --extended-regexp "^[0-9a-f:.]* 0280: 168c:002b" || exit 0 # configure the device to use antenna 1 (Main) for both tx and rx iw phy0 set antenna 1 1 end script To manage notifications about this bug go to: https://bugs.launchpad.net/network-manager/+bug/1061924/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
