[SOLVED] Wireless connection drops randomly couple of times a day

My laptop disconnects from my wifi maybe once or twice per day.
I just bought a new router and also upgraded all my packages so I'm not sure which is causing this.

[krey@krey-laptop ~]$ sudo systemctl status netctl-auto@wifi

The only way I've been able to fix it is by restarting the router. But my phone wireless works fine, so it's not entirely the router's fault.

[krey@krey-laptop ~]$ sudo lspci -v

	Subsystem: Intel Corporation Dual Band Wireless-AC 7260

The router is a TP-LINK TL-WR720N (crappy, I know, but I needed something cheap quickly)

Any help would be much appreciated!

Sometimes it’s just a bad wireless adapter. At the moment, I happen to have a small netbox computer w/ built-in wireless adapter. Does the very same thing. It drops the wireless connection after several hours, only a reboot restores it.

Check that "Power Management" is disabled is the output of `iwconfig`

Thank you, disabling power management solved the issue.
