No ethernet connection on Lubuntu 17.04 - message says I'm connected
I just now got Lubuntu 17.04 to install, boot, and run on UEFI.
My ecstasy was short-lived.
I ran Firefox and it will not connect to anything.
I set up a DSL connection. The computer says I'm connected.
I tethered the computer to my phone. The computer says that Wired Connection 2 is active.
I'm ready to use my netbook as a Frisbee.
I would download lubuntu restricted extras, but, I can't get online.
Any ideas, anyone?

What says ifconfig -a ?
Can you update your system?

Hi...
Can you ping out? Please open a terminal post the results of...
Also, please post the results of these commands, as well...
Code:
lspci -nnk | grep -i net -A2
Code:
sudo lshw -C display
Code:
dmesg | grep -iC 3 "eth0"
This will give us additional information concerning your ethernet device and possibly help us find a solution to your issue. You can simply save the results to a text file and then move the file to a thumb drive. Then you can transfer the file to a computer that has an internet connection.
Disclaimer: Be careful with commands that are prefaced with "su" or "sudo." They will essentially allow root access to your system. Mistakes could possibly damage or even destroy your OS.
Regards...

Have you tried using network-manager to manage your network. Also, if your connecting to a router or WAP, it will say you have a connection even if you don't have an Internet connection.

I was able to ping bing.com
The Great Firewall of China precludes Google.
I was also able to connect to bing.com for a few minutes, though not to any of the sites I tried outside of China.
I tried the ifconfig -a command and was told to get net tools. I could not connect.
I'll try again from time to time with the terminal commands.
I've installed Mint 17 and that has worked. I'm now 2 out of 7. Perhaps I'll just wind up using Mint instead of Lubuntu.
Sincere thanks for all the helpful responses. I hope to be able to put back one day.

So Firefox could be telling the truth; the computer is connected... To the phone. (i.e. It can "see" the modem in the phone) Perhaps it's something to do with the interconnection between computer, phone and your phone service?
Just my

My two concerns du jour:
I now get a message showing that (my phone) is not connected when it is connected.
When I connect the USB cable to the computer from my phone, the "Wired Connection 2" message appears.
Also, the name of my phone (Huawei) appears. Also, the word "disconnected" appears.
All this appears faint and cannot be clicked. It all vanishes when I remove the USB cable.
I downloaded exfat-utils and net-tools deb packages using another OS. I copied them into my ailing Lubuntu installation.
When I use synaptic or software manager in Lubuntu, both programs acknowledge the packages but neither program will install either of the packages.
I don't know if this is relevant, but the installer crashed when I installed Lubuntu. It was unable to install GRUB2 and the install process halted. (I boot Lubuntu with a menu entry in Mint Rosa.)
I have no idea if this is related to my two headaches with Lubuntu.

I don't think it's related. It was probably an installer bug. Check whether or not the phone is recognized as a modem or USB storage: Add -v for more info.

The phone is seen as a modem.
I've copied the net-tools and exfat-utils packages from Linux Mint (/var/cache/apt/archive) and I finally stumbled upon dpkg -i *.deb and installed them. I was able to run the laundry list of terminal commands suggested by Ardvark71.
I've thought of one thing that might be sabotaging my phone. I use a DSL connection, and the DSL connections seems to be used automatically, whether I connect to the land line or to the phone. The DSL is for the land line, so it works, albeit poorly. The phone doesn't connect at all.
I just tested the theory by booting a live USB. It has never had the DSL connection. Both the phone and land line showed. I disconnected the land line. It still showed I was connected to the phone. I was able to use Firefox, all sites.
You wouldn't believe what other convoluted paths I've been down.
Again, thanks for the responses.
