My boot time increased if the connected wlan network is not available. If the connected network random_rants is not available it takes more time to boot.

My etc/network/interface configuration is: 

auto wlan0
iface wlan0 inet dhcp
    wireless-essid random_rants

__

Listening on LPF/wlan0/0e:20:4e:a5:3d:0a

  • This is because the interface waits for DHCPOFFERS. You can speed this up by using a static ip.

  • Actually I use my wifi in bot access point and client mode. During AP mode I set static IP. While client mode where I can connect other internet networks, in that I m using dhcp. Just changing static ip during client will reslove the problem ? or having a script at rc folder during boot up to set static IP ? I want to connect the previous connected network when I turn on the device. Does setting static IP will help ? thanks for the reply.

    Others who face this problem I figured out the way actually. I used static IP during the pre-down and pre-up in order to avoid dhcp to stuck for 30seconds timeout till it finds the network. After using static IP boot time is normal as it was earlier. Ö.Ö
