My wireless adapter (AWUS1900 with this driver https://github.com/aircrack-ng/rtl8812au.git) still disconnects and reconnects and after a bit, it disconnects and can't reconnect to the network; I have to reboot the system. It make me crazy !
Every time this happen, I see this message on dmesg command
[ 3827.872912] audit: type=1107 audit(1575393261.050:191): pid=1017 uid=103 auid=4294967295 ses=4294967295 msg='apparmor="DENIED" operation="dbus_signal" bus="system" path="/org/freedesktop/NetworkManager" interface="org.freedesktop.NetworkManager" member="PropertiesChanged" name=":1.12" mask="receive" pid=2175 label="snap.telegram-desktop.telegram-desktop" peer_pid=1047 peer_label="unconfined"
exe="/usr/bin/dbus-daemon" sauid=103 hostname=? addr=? terminal=?'
and it is full of this messages.
What is it mean ? Is it related to my problem ? How can I fix it ?
Another strange thing is that every command to modify the wireless behavior doesn't seem to work. For example if I type:
iw dev wlan0 get power_save
it return on so I set it to off
sudo iw dev wlan0 set power_save off
and it works for a while and then it back to the previous status (power_save on). I also set the usb suspensions to -1 on the kernel boot to not suspend the usb and make the wireless stop working.
But if I put my phone in hotspot mode (close to my wireless) my pc goes online instantly.
