WiFi disconnects after some time

I've configured my office WiFi on my Arch Linux system and it gets disconnected after sometime. I'm unable to ping the router (192.168.1.1) or any other remote IP address. The system works fine in my home WiFi network.

Hardware:

Model: Lenovo E470

WiFi adapter:
05:00.0 Network controller: Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter (rev 31)
    Subsystem: Lenovo Device 0901
    Kernel driver in use: ath10k_pci
    Kernel modules: ath10k_pci

Software: wifi-menu and netctl

$ uname -r
4.10.11-1-ARCH

I generated the profiles using the wifi-menu utility which stored all the profile data in /etc/netctl. It'd be great if someone could provide some pointers to troubleshoot this issue.

Re: WiFi disconnects after some time

So, you have not enabled any network management...

Re: WiFi disconnects after some time

I've netctl and wifi-menu installed. I was running wifi-menu manually to generate the network profile for the first time. Post that used wifi-menu to connect to the access point.

At my home wifi network, the network works perfectly fine. But I'm facing issues in my office wifi network. It connects to an access point and after sometime the connection gets dropped.

I've enabled the unit from systemctl now. Still the network gets disconnected after some time.

Re: WiFi disconnects after some time

I did a quick search on (Reason: 3=DEAUTH_LEAVING) and found it is not a new problem. This older post may be relevant to your problems, OP.  https://bbs.archlinux.org/viewtopic.php?id=218875  It involves ca-certs, so that may also be related to the recent ca-certificates changes as mentioned on the archlinux.org front page.
