wpa_actiond watches the wireless link and kills dhcpcd when appropriate. When the network goes down shortly (less than 30 seconds), then dhcpcd still removes the IP and re-acquires the lease. This is unnecessary, and breaks connectivity for a few seconds more than needed: 00 dhcpcd[1181]: wlan0: carrier lost 00 wpa_actiond[832]: Interface 'wlan0' lost connection to network 'XXXX' 04 dhcpcd[1181]: wlan0: carrier acquired 04 wpa_actiond[832]: Interface 'wlan0' reestablished connection to network 'XXXX' 04 dhcpcd[1181]: wlan0: rebinding lease of 11.22.33.44 04 dhcpcd[1181]: wlan0: acknowledged 11.22.33.44 from 11.22.33.33 04 dhcpcd[1181]: wlan0: checking for 11.22.33.44 09 dhcpcd[1181]: wlan0: leased 11.22.33.44 for 1800 seconds Here, the wireless link was reestablished after 4 seconds, but the connection was usable after 9 seconds. --- scripts/netcfg-wpa_actiond-action | 4 ++-- src/connections/ethernet | 2 +- 2 files changed, 3 insertions(+), 3 deletions(-) diff --git a/scripts/netcfg-wpa_actiond-action b/scripts/netcfg-wpa_actiond-action index 3547fef..71ffcf7 100755 --- a/scripts/netcfg-wpa_actiond-action +++ b/scripts/netcfg-wpa_actiond-action @@ -11,10 +11,10 @@ action="$4" case $action in CONNECT) if [[ -z $profile ]]; then - dhcpcd "$interface" + dhcpcd -K "$interface" exit $? fi - if ! $CONN_DIR/ethernet up "$profile"; then + if !
