Bug Description

There are many problems reported about random and quick disconnect/reconnect of the wireless connection in ubuntu. Some say, disabling the ipv6 is the solution but it isn't!

I really do want to find a way to debug what happens that the wireless connection drops randomly. But I couldn't find a tool for that.

The output of the following commands are attached:
uname -a
ifconfig
cat /proc/sys/net/ipv6/conf/all/disable_ipv6
iwconfig
lsmod
dmesg

I encounter the same problem with the daily Xubuntu 18.04 and Ubuntu MATE 18.04 of March 5, 2018. The connection via ethernet cable does not work unless I disable the ipv6.
In practice I have to set the Method to Ignore in IPV6 Settings to navigate.

@Marco,
I also have disabled IPV6 but still the same thing happens. Many users reported that problem and I see many post for older ubuntu versions. That is a very annoying bug.

In my case it works also by setting the IPV6 to "Automatic, address only".
Try like this. Turn off the connection, set it to Automatich, address only or "Ignore" and then re-enable the connection. In my case this procedure works (see attachment)
