I am sure there will be a fix.

Firstly are you using a wired connection or wifi?
When it goes down what is the network icon in the top bar showing (it
should show two arrows or a fan with bars in it when it is connected).
When the network is working open a terminal and type
and hit enter.  Copy/paste the output here.  In case you don't know,
use Ctrl+Shift+C to copy from the terminal.
Then when it is down repeat the command and again copy/paste it here.
