I have been running on LMDE betsy for few months
with a lenovo g580 2189 i3 laptop
atheros ar8162 is my ethernet card
I have been encountering a problem with my Ethernet connection for about two weeks now,
the connection works perfectly for about 5 minutes, sometimes less sometimes more,
and then it drops,
on firefox the new open pages stayed blank loading endlessly then resulting in "unable to find page
on chromium it says "DNS_PROBE_FINISHED_NO_INTERNET"
If i unplug my Ethernet cable
and then plug in again
it solves the problem, but only for 5 minutes or so
I tried to plug in another router and the problem stayed the same
If I connect through wifi though I have no problem
if I use Ethernet through window 7 (i have dual boot) then no problem
