I've installed Ubuntu Mate 16.04 on an Acer 'aspire one' D 260. The inbuilt mobile broadband modem is not recognized any more after using the first time suspend mode. It was working from the life stick I have installed Ubuntu, so in theory it should work but it's gone from network manager.

I just had put in another SIM card, Ubuntu is asking for the pin, and I can go online but after the first suspend it is gone again :(

  • If you shut down and restart does it work as expected? – Elder Geek Jul 31 '16 at 18:37
  • surprising with the new SIM card it is connecting automatically after restart. But it did not so with the old card. – Asklep Jul 31 '16 at 19:23
  • Pardon my confusion. I was under the impression that the problem occured coming out of suspend. – Elder Geek Jul 31 '16 at 19:58
  • yes, it is coming out of suspend. now after suspend the problem is there again :) – Asklep Jul 31 '16 at 20:09
  • Have you tried my answer? – Elder Geek Jul 31 '16 at 20:11

I've seen this problem with numerous operating systems. the driver isn't re-initialized when coming out of suspend and has to manually be disabled and re-enabled to properly start. The easiest way I know of to accomplish this (regardless of operating system) is to reboot or shutdown and restart.

Another thing you could try would be to stop and restart the networking service


Another approach which may work for you is tag the driver for unload on suspend and reload on resume.

1) First we need to identify the driver in use. We can do this with the command sudo lshw -C network | grep driver (copy the driver name that comes after the driver= from the output of the command)

2) Next we need to write a configuration file with the command sudo gedit /etc/pm/config.d/config

sudo gedit /etc/pm/config.d/config

Add a line that says SUSPEND_MODULES="driver name" where driver name is the value that you copied above. This does not always work but might in your case.
