Ubuntu boot very slow with wifi driver - remainder - 06-15-2016

Hi,
I recently moved over to the Ubuntu image after longsleep stopped supporting the Arch version. However, I'm now getting very slow boot times of up to 5 minutes, and the issue seems to be with the wifi driver:

Does anybody have any ideas on solving this? Updating to the latest kernel version using the scripts from longsleep's repo hasn't helped.

RE: Ubuntu boot very slow with wifi driver - jacobscarter - 06-15-2016

I know longsleep has a comment somewhere saying it tries to connect to the Internet on boot (and will continue to try for 5 minutes before it gives up). For example if I boot mine when connected to Ethernet it starts right up but if Ethernet is not plugged in the boot takes five mins.

RE: Ubuntu boot very slow with wifi driver - longsleep - 06-15-2016

If you do not connect Ethernet this is expected until you change the configuration.

RE: Ubuntu boot very slow with wifi driver - remainder - 06-16-2016

I just deleted /etc/network/interfaces.d/eth0 and that did the trick. Thanks for the help!

RE: Ubuntu boot very slow with wifi driver - robregonm - 08-23-2016

Any news/fix on this?
Maybe a way to configure the timeout...

RE: Ubuntu boot very slow with wifi driver - longsleep - 08-23-2016

The fix is that you change the configuration to match your use case.

Indeed. If you want the ethernet to not black startup when the cable is not connected, you'll need to either disable it, or configure it to allow for hotplugging. 

Depending on your network setup, this may be as simple as changing /etc/network/interfaces to read 'allow-hotplug eth0' instead of 'auto eth0'. This allows the system to configure the device it if is plugged in later. 

In my case, this means the part of my /etc/network/interfaces file that deals with the wired ethernet looks like the below snippet, and setups up my ethernet connection when and if the cable is plugged in. 

Code:
#auto eth0 #commented out to prevent blocking system startup if cable not plugged in
allow-hotplug eth0
iface eth0 inet dhcp

If you have a more complicated network setup, you may find you need to consider using the systemd-networkd daemon, but in my case that wasn't needed.

RE: Ubuntu boot very slow with wifi driver - victorssantos - 08-02-2017

I know that is a old topic (1 year) but I tried allow-hotplug, tried static IP and it keep needing 5 minutes to boot.

Is delete the /etc/network/interfaces.d/eth0 best solution?

If you have altered it so that it now says allow-hotplug eth0 instead of auto eth0, then yes, you'll need to delete (or perhaps just move so you don't have to re-create it if it doesn't fix the problem?) the eth0 config file.

RE: Ubuntu boot very slow with wifi driver - victorssantos - 08-03-2017

I made a mistake.

I didn't know that I have to configure eth0 interface inside interfaces.d folder. I used the interfaces file and that's why it didn't work.

Removed eth0 file.



Thank you!
