Just upgraded from Ubuntu 16.04 to 16.10. Everything works great so far. Except when I "suspend" it, wake it up, the wifi does not work unless I restart my computer. The strange part is, the icon indicates I'm connected and i'm able to connect to every network successfully, but when I go to the browser its a no go. Here's the steps I've taken to attempt a permanent solution:

  • turned my wifi on and off
  • deleted saved wifi networks
  • added networks back again and tried connecting to several different networks (still doesn't work after this)
  • sudo apt update & upgrade
  • Go to terminal, use sudo service network-manager restart

The final step above restarted my internet connection and within 10 seconds i'm back online again. However, I don't want to have to do this every single time I wake up my computer.

Any ideas?

Terminal :

sudo ifdown wlan0 && sudo ifup wlan0

Solution 1:

sudo nano /path/to/script.sh

#!/bin/bash
sudo ifdown wlan0 && sudo ifup wlan0

crontab -e:

@reboot  /path/to/script
  • found out my wireless card isn't called "wlan0" (see below) . How do I determine which one it is? ifconfig -a lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10<host> loop txqueuelen 1 (Local Loopback) wlp58s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 10.100.59.123 netmask 255.255.248.0 broadcast 10.100.63.255 inet6 fe80::18f2:af03:c9cb:8235 prefixlen 64 scopeid 0x20<link> ether 30:52:cb:e7:1d:35 txqueuelen 1000 (Ethernet) – lsch91 Nov 14 '16 at 18:31
  • also its not on reboot it doesn't work, but instead on waking up from suspend – lsch91 Nov 14 '16 at 18:34
