Ubuntu 18.04 Wifi network (internet) connection breaks up every time the computer wakes up from the sleep...
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;
}
Ubuntu 18.04.01 is losing the Wifi internet connection every single time it wakes up from sleeping / suspend mode. The PC is a notebook Acer Aspire V3 772G. It never happened with older Ubuntu versions and it still never happens with Windows 10, which is installed as dual boot. The router is a Vodafone DSL-EasyBox. It is not clear to me if the problem began after an update or after I started using this router, 4 months ago.
What I've tried so far
I tried this solution manually: Wifi doesn't work after suspend after 16.04 upgrade, also presented in https://ubuntuforums.org/showthread.php?t=2355314 which suggests running the command
sudo systemctl restart network-manager.service
It randomly works after about 2 to 8 times running this command or it doesn't. In the negative case, I have to reboot the OS and eventually reset the router, what is not always possible to do when living in a shared apartment and is anyways really annoying.
Tried to check entering ip link, lshw -class network and /sbin/ifconfig whether the network device and the router are being seen from the PC and yes, they are. /usr/sbin/arp -an also returns me the correct IP address and ethernet configured for network using.
What I tested and found out
Whenever the internet is not working:
- It is not possible to ping any website, as well
- I can't access the router through its IP-address from the browser, the browser keeps loading it endlessly
- The network device and router are seen by the PC as described above.
