ive read through similar posted questions and have not gotten any consistent results.
i have a lenovo laptop, with windows 10, i just installed ubuntu 15.10 beside windows. everything seems to work fine with ubuntu except the internet. it says that my connection to the network is strong, i have even connected to several different networks (all wifi) which all demonstrate the same problem.
the problem presents in the following manner, when i first turn the computer on, or restart ubuntu, the internet works fine for a few minutes. then, while still connected to the network, i am unable to access any internet sites. i am unable to sudo apt-get install/update/... anything. says repositories are unfound or something.
i am typing this from the same computer, from the same network, while being booted from windows.
ive tried running a few command line tools i was suggested to run to ensure my wireless card was working ok, ive ensured ivp4 is set to automatic (dhcs) or whatever, ive tried setting ivp6 to ignore (which incidentally seemed to work for a while, like 45 minutes, thought that fixed the problem till it started happening again).
so, while being ignorant to alot of these things, it doesnt seem to be a network thing, because this has happened on several different networks. it doesnt seem to be a hardware thing because windows works just fine. ive heard people talking alot about DNS and TCP/IP network protocol stacks, all of which i have a loose understanding of.
so id like to get some direction to getting this issue with ubuntu resolved, and also gain a little understanding of these things that may be causing a problem. thanks again for help.

. That's all that is. When you have it set to automatic - it assumes translator provided by your router. You could also set your own. From drop down menu under the network icon you should see "Edit Connections" option. That option should spawn a small window with list of networks. Select your network under wifi, click edit , and under ipv4 settings selectAutomatic (DHCP) Address only
. Now, where it says DNS servers, set8.8.8.8
address. Save and reconnect. Does it help ?ping -c 4 8.8.8.8
and thenping -c 4 google.com
and let us know which one succeeds , which one doesn't. That should be sufficient to see if it's DNS or not
