Delay on boot with wireless network

Bug #105414 reported by stefanokan on 2007-04-11
Affects Status Importance Assigned to Milestone
ndiswrapper (Ubuntu)

Bug Description

I have installed Feisty Beta and all last updates.
The hardware is a laptop HP nx6310 with Broadcom 4311 wireless device.
I have installed ndiswrapper version 1.41 and extracted windows driver for my card.
Data is WPA2 encripted. All is working correct.
The problem is at boot.
It is delaying roughly 30-40 seconds.
If i cut the wlan0 in /etc/network/interfaces then the boot is fast.
Here is my /etc/network/interfaces:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

auto wlan0
iface wlan0 inet dhcp

I want to specify that in previous edgy eft version i did't experienced this problem.

Hi, did you have same problem with Feisty Fawn final version?
I loaded all the last updates so i think should be the same version as the
final but the problem is still the same. No answers by launchpad.

Yes feisty final version. I am also using ndiswrapper for broadcom 4306
chipset. This problem is very annoying because I cannot fix it through
/etc/network/interfaces as I need to automount network folders on startup.

I confirm this bug on Feisty. I am using ndiswrapper on a Broadcom BCM4309 rev 02 If i uncomment my wireless section in this case (wlan0) from /etc/network/interfaces the machine boots fast but my wireless card is not detected. I guess the question is, how do I force it not to try obtaining an IP address from my wireless during boot time? The problem is that it just times out then continues booting without a network detected on it.

I think this bug is not related to ndiswrapper but to the script found here: /etc/rcS.d/S40networking
Look at the TIMEOUT section been established around line 20. Is there a way to "blacklist" the card so that it skips this step? The key is to only blacklist it from this step alone.

Here is my /etc/network/interfaces:
auto lo
iface lo inet loopback

auto wlan0
iface wlan0 inet dhcp

I found a solution that appears as a workaround.
I red this post by Tormod Volden :
and tried this:
sudo update-rc.d -f networking remove
Than rename the script networking inside /etc/init.d/ (e.g /etc/init.d/networking.bak)
Than reboot.
Than i had no more delay but the wireless networks did not work.
Make a backup of etc/network/interfaces (e.g. copying as etc/network/interfaces.bak)
Than rename /etc/init.d/networking.bak in /etc/init.d/networking
Give command: sudo update-rc.d networking multiuser
Rename etc/network/interfaces.bak in etc/network/interfaces
Now you should have no delay on boot and the wireless network on.
I did not understand why, but it works.
Good Luck.

I've seen the same behaviour on Hardy. Not only on wireless interfaces. If I start my laptop without any network connection at all the boot time is significantly higher.
