I have an ASUS X550VX laptop, on which I recently installed Antergos. Previously, I had Kubuntu dual booted with Windows 10 (W10 is still on PC, I replaced Kubuntu with Antergos).
I use a Realtek rtl8821ae wireless card, at least lspci -k gives
“Network controller: Realtek Semiconductor Co., Ltd. RTL8821AE 802.11ac PCIe Wireless Network Adapter”
I experience issues with my wifi at home.
The symptoms are:
At one point, usually once every 2-10 mins, I lose internet connection, while the system tray indicator still says I am connected, then the signal strength drops to near zero, I get disconnected, then in a few seconds it reconnects.
Sometimes it won’t be able to reconnect at all, and I need to reboot the OS (probably removing and then reloading the kernel module also does that).
This is most likely an issue with my driver. I had no prior issues with the router, and wifi worked fine on Kubuntu.
I use Gnome 3 with the standard config as installed by cnchi. I connect to wifi via the system tray plugin on Gnome (which by the way sucks and gets unresponsive even when trying to totally turn off the wifi).
Direct ethernet connection works. At least that’s what I thought, but just as I wrote this, it also disconnected and I had to reinsert the cable.
Attempted solutions: I created a file /etc/modprobe.d/rtl8821ae.conf where I added
“options rtl8821ae ips=0 swlps=0 fwlps=0”
but this did not fix the issue.
I realize this is a fairly widespread issue, at least internet searches gave me many results, but the above solution was the only one I found that I could safely apply. I have found some other stuff but were for different network cards or different distros.
I would appreciate any help, as I really like Antergos and would like to make it my long-term OS, but if wifi is gonna misbehave like this I’ll probably have to switch to another distro.
Many search results gave me threads in which people apparantly solved the issue by undergoing a kernel update. Neofetch says I use 4.11.5-1-ARCH, and since Antergos is a rolling release distro and pacman -Syu does nothing, I assume my system is fully up to date.
