First of all,thanks for your time and help.
I just installed Ubuntu 18.04 LTS Desktop on my Asus TP500LA , and when I close the lid or suspend, my wi-fi is still connected but I have no internet access (not always, sometimes when I resume the wi-fi is OK) until I type the following
sudo systemctl restart network-manager.service as I saw in this post: Wifi doesn't work after suspend after 16.04 upgrade , but the airplane mode led always turns on, thing that doesn't happen on Windows. I don't know what do I have to do to fix this, I've tried some stuff but nothing seems to work. I attach the output of command
03:00.0 Network controller: Qualcomm Atheros AR9462 Wireless Network Adapter (rev 01) Subsystem: AzureWave AR9462 Wireless Network Adapter Kernel driver in use: ath9k Kernel modules: ath9k
If you need more information please let me know.
