This should be a sticky as the same subject comes often on the forum.
This is valid for all Linux versions that use network manager, like Debian wheezy or jessie or stretch, ubuntu, linux mint etc.
Mesa card should be wired directly to the PC, not over a switch or HUB or router.

====Network setup for mesa cards: ======
- left click on the network manager on the bottom right side or upper right side where the clock and volume is.
- choose "edit connections"
- double click on the network you want to edit ( usually "wired connection X")
- click on the "IPv4 settings" tab
- choose "manual" on the "method" drop down menu
- click on "add"
- write the address as 10.10.10.11
- never use 10.10.10.1 or 10.10.10.10 for the above
- netmask should be left as is ( usualy 8 )
- gateway should always be 10.10.10.1
- additional DNS servers should be 10.10.10.1
Save, close, left click on the network manager and click on the "wired connection X", it should take about 3 seconds to reconnect. Now open a terminal and do Ping 10.10.10.10, you should get normal reply form the Mesa card. If you do not get a reply, double check your settings.

>>> If you want to use another connection or a wireless connection for internet, you have to set up everything as above, set up internet, and ONLY after having internet working edit the wired connection X going to Mesa card again as follows:
- network manager>edit connections>wired connection X>IPv4 settings> ROUTES > just click on the "use this connection only for resources on its network"> OK>save>network manager>reconnect to that network.

If using intel ethernet that in some cases looses the connection, there should be the following line added in a terminal

sudo ethtool -C [your_ethernet_device-name] rx-usecs 0
Test the ping again and check the reply time.
