Having a problem I have not yet experienced. I made a fresh install of 17.04 and now I have noticed my link to internet goes down and then back up randomly. Have noticed when I download some files via torrent, after a while speed drops down to 0 and then goes up again. THe wifi signal shows good connection but still the link goes down. When network is down I cant access webpages or anything. If I wait 1-3 minutes everything comes back again, and after a while goes down again....arrg..
How to troubleshoot where problem is?
lspci -knn | grep Net -A3; rfkill list
