_ iwlwifi のバグ?

最近無線がブチブチ切れるので, log を見てみたら

んー? これか?

• Red Hat Bugzilla - Bug 787446 - Wireless Dropout - Tx aggregation enabled on ra

とりあえず /etc/modprob.d/iwlwifi-temoprary-fix.conf として

options iwlwifi 11n_disable=1

としておく.

_ nmcli が動かない

今日の upgrade で network-manager が更新されたのだけれど

$ nmcli con up id <設定名>
Error: Can't obtain connections: settings service is not running.

むぅ. nm-applet 経由だと接続できるので, なんだろうね.
