Make Network Manager restart after dropped connection?
I configured the pppoe connection in network manager it works perfectly fine when i start my computer after some couple of hours/min the network gets disconnected. When i check the network manager it says wired connection unplugged so when i restart it works fine again.
Can anybody help because I dont want to restart my pc again and again .
Please try these two solutions. Unfortunately I don't have a mobile broadband connection to try them out.
Right-click on the NetworkManager applet in Gnome, and select Edit Connections. Highlight "System eth0" and click Edit.
Go to the IPv4 Settings tab Click the Routes button Make sure the checkbox "Use this connection only for resources on its network" is CHECKED. Click OK to save the setting.
Then make sure that the checkbox is NOT checked for "apply settings to all users", and click Apply.
Otherwise, the setting above cannot be changed by an ordinary non-root user (it won't save the changes). Unchecking this allows the setting to be changed for the logged in user and therefore everything will work.
Now, time to apply the trick.. In PPP settings tab, disable “Use Point-Point Encryption (MPPE)” as follows.
