First, identify the driver for your network device with the command: lshw -C network Look for driver=. Next, check the log for clues as to why the device disconnects. I suggest you look at both the driver and what Network Manager is doing: cat /var/log/syslog | grep -e some_driver -e etwork | tail -n 20 Ideally, run this just as the internet ...

Here's a very simple bash script. Make it executable with chmod +x and add as custom startup application to run this continuously on every login. Since I've mentioned aplay, this should work in command line, not just gui. My current laptop doesn't have sound,so i had to test everything with notify-send . Feel free to adapt the script as necessary. ...

Your stanzas for IP aliases should have minimal data and an auto statement for each. I prefer to use the last octet as the alias number. This is the configuration I would use. auto p2p1:116 iface p2p1:116 inet static address xxx.xxx.xxx.116 netmask 255.255.255.0 auto p2p1:117 iface p2p1:117 inet static address xxx.xxx.xxx.117 netmask ...

You should not need to use static settings instead. Also, I see that you have already found this answer For a dynamic IP address solution, you should set up a real bridge and use it. Your interfaces file should become: # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). ...

You can call it from the file /etc/rc.local. You can either add the lines to that file or call the script there. Whatever you choose you have to add it above the line 'exit 0'. BTW: I suggest you add a wait command after the first network restart because it can take a few seconds for the network to start. If the ping comes to early you can get an incorrect ...

What you describe seems like dhcp lease issue. When you connect to the router, dhcp gives you ip for some particular amount of time ( that's what's called lease ), and then that gets renewed. For example, here's what I have in my syslog: $ grep 'renew' /var/log/syslog Jun 30 20:38:01 anaconda dhclient: bound to 192.168.43.209 -- renewal in 1342 seconds. ...

If you wish to continue with /etc/network/interfaces, wireless will require the addition of the network you intend to connect to and any encryption details. I suggest: auto lo iface lo inet loopback auto wlan0 iface wlan0 inet dhcp wpa-ssid mynetwork wpa-psk 0123456789 Restart the interface: sudo ifdown wlan0 && sudo ifup -v wlan0 Check: ping ...

So apparently I fixed this myself. Tonight i changed my linux kernel for giggles and that fixed it. 3.19.0.21 breaks the DHCP requests, but they work again in 3.19.0.15. so that was the issue with my particular problem.

Assuming, your script has the name sound_notifier and it's placed in /usr/bin: sudo chmod +x /usr/bin/sound_notifier Create a script /etc/network/if-up.d/start_sound_notifier sudo nano /etc/network/if-up.d/start_sound_notifier add the code below #!/bin/sh if [ "$METHOD" = loopback ]; then exit 0 fi # Only run from ifup. # if [ "$MODE" != start ]; ...
