I have a problem with Wi-Fi on a Dell laptop with a Qualcomm Atheros QCA9377 802.11ac wireless network adapter. WiFi somewhere every 5-10 minutes just stops receiving and sending data. I can not connect to the router (192.168.1.1) too. If I just reconnect to the hotspot, then the next 5 minutes Wi-Fi is working.

Does anyone have any ideas on how to fix this annoying problem?

Problem fixed by changing router settings.

Changed Channel Width from auto to 20MHz.

Original: https://ubuntuforums.org/showthread.php?t=2414770

If anyone still has problems...or wants the channel width back to auto: Try installing linux kernel 4.19 or up. It fixed my problems....
