LAN trouble with VPN in Ubuntu 14.10

[tapasray]

Ok, think I got it (the formatting thing).

I think you are referring to the error after

 gedit /etc/network/interfaces

. Since i hadn't [sudo], I could not save the edited file. Once I used [sudo] I could. So the content of /etc/network/interfaces is now

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

I'm not sure what else to post for this.

"hadn't used [sudo] ..."

[michi1983]

okay now reboot your computer again and post the output of

sudo ifconfig

again

Hi! It's freezing up during reboot at various points. Sometimes just black screen, so I have to power off. Sometimes stuck in GRUB. Sometimes waiting for "full network configurations" and then loading "without full network configurations." After this sort of load, the wifi icon at the top doesn't show for 10/20 seconds.

Here's the [ifconfig] o/p --

tapas@tapas-VPCYB35AN:~$ ifconfig

Alright, so the bridge is finally gone.
Now please edit the file again that it looks like this:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

auto wlan0
iface wlan inet dhcp

Then restart your computer again.

Post again the output of

sudo ifconfig

We are getting closer

Thanks! Right away ...

Oh man, something is still messing up here :/
At least your eth0 tries to get an IP address from somewhere but it seems that no DHCP server is answering.

I am not sure if I have asked already but to what is your computer connected? A wifi-router/modem? If yes, can you please post some screenshots on your LAN settings from the router.
You are 100% sure that you have a working cable connected from the router/modem to your computer?

[tapasray]

Hi. I do have a working cable connection. Right now, since ethernet is not working, I'm on wifi: ADSL cable --> Modem/router --> WiFi --> Computer.

Attaching a screen shot of the cable connection's IP4 settings.

PS: The 'VPN Connections' entry is still there in the network (scroll-down) menu.

[michi1983]

Wait! Your attached screenshot is from which device? From your Ubuntu machine?

[tapasray]

Yes. the laptop running Ubuntu.

[michi1983]

Jesus Why is it on manual? You are interfering with the /etc/network/interfaces file if you set that to manual. Because we set the /etc/network/interfaces file to DHCP.
We first wanna try if everything runs fine when set to DHCP. So please change that from "manual" to "automatic/dhcp" and lets see if you get an IP from your router.
