I am having a problem similar to this question: Losing Wifi on 12.04, no way to get it back?
On a machine where the problem doesn't manifest with windows and even in other machines, my wifi just randmly dies multiple times a day. there is no warning, sometimes it works for hours, sometimes in minutes but eventually it is guaranteed to happen. Wether the machine is iddle or working doesn't matter.
lspci output:
6:00.0 Network controller [0280]: Intel Corporation Wireless 7260 [8086:08b1] (rev bb)
Subsystem: Intel Corporation Dual Band Wireless-AC 7260 [8086:4070]
Kernel driver in use: iwlwifi
Kernel modules: iwlwifi, wl
The only way I have found to fix it is rebooting. I have also tried resetting the network manager with systemctl but that doesn't fix it.
The wifi dying is not that much of an issue, but having to reboot to fix it is a chore, is there a way to emulate restarting the computer but only in so far as the wifi/network adapters are concerned? just so that I don't have to re-open every program I am using.
Windows
