Here's a script that will get the wifi back up and running again without a reboot:
``` #!/bin/sh # If an interface name was not passed in then assume that wlo1 is the interface name. if [ -z "$1" ]; then interface="wlo1" else interface=$1 fi # Figure out what pci slot Linux has assigned the Network controller: Intel Corporation Wireless 7260 wirelessPCI=$(lspci |grep "Wireless 7260") pci=$(echo ${wirelessPCI} | awk '{ print $1 }') devicePath="/sys/bus/pci/devices/0000:$pci/remove" # Not the best solution as this script can hang. # But since if this script fails the ONLY way to revive the wifi anyway is a reboot... # Feel free to improve the script if you have the scriptfu ninja skills to do so. while true; do # Tell Linux to remove the wifi card from the PCI device list only if it exists in the first place. if [ -f $devicePath ]; then echo 1 | sudo tee $devicePath > /dev/null sleep 1 fi # Reprobe the driver modules in case we have removed them in a failed attempt to wake the network card. sudo modprobe iwlmvm sudo modprobe iwlwifi # Try to have Linux bring the network card back online as a PCI device. echo 1 | sudo tee /sys/bus/pci/rescan > /dev/null sleep 1 # Check if Linux managed to bring the network card back online as a PCI device. if [ -f $devicePath ]; then # Looks like we are back in business. # So we try to set the PCI slot with some voodoo I don't understand that the Intel devs told me to try. # https://bugzilla.kernel.org/show_bug.cgi?id=191601 sudo setpci -s $pci 0x50.B=0x40 # Bring the wireless network interface up. sudo ifconfig $interface up # Did the wifi interface actually go live? exitCode=$? if [ $exitCode -eq 0 ];then # Not sure why in the hell this is not the default for wireless intefaces. # It is well documented that: (power_management === ON) === Wifi-Stupidity sudo iwconfig $interface power off # The exit code will be the exit code of our attempt at turning power management off for $interface/wlan0. break fi else # It's worse than that the wifi's dead Jim! Dead Jim! Dead! # We tell Linux to remove the the wifi driver modules and loop back in an attempt to revive the wifi. sudo modprobe -r iwlmvm sudo modprobe -r iwlwifi fi done ``` -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1673344 Title: Ubuntu 16.04 doesn't recongnize wifi card after loosing signal completely (intel 7260) even when I try to restart network manager To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1673344/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
