I have the problem as stated in the title. I started this question in another Forum as below.

 

https://www.bleepingcomputer.com/forums/t/636616/wifi-and-ethernet-connected-but-internet-not-working/#entry4155898

 

It was suggested that I move the discussion here.

 

Please review what I have already posted and offer any help that you can.

As stated in my other postings, my technical level is High and I've been through a lot of steps to get me to this point.

 

Assistance?

Press the "Windows Button" and "R" simultaneously.

A small window called "Run" will open, in here, type cmd

Click on ​OK

 

A new window (with a black background) will open.

In that window, type in cd Desktop

​Then, in that window, press ENTER

 

Then type in that same window ipconfig /all > ipconfig.txt

Go to your Desktop and open the file "ipconfig.txt".

Copy and paste the content of that file here.

 

1. You may wish to omit the "Host Name" part, because of your privacy!! (in case your hostname includes real names of you or someone else)

2. If you do already have a file called "ipconfig.txt" on the Desktop, then you may wish to move that file somewhere else, otherwise it is being replaced.

#1
Which Firewall are you using?
 
#2
Can you ping 127.0.0.1 ?
And can you ping 8.8.8.8 ?
And can you ping google.com ?
 
I have read your other posts, but I don't think that will change my postings to this topic.
Don't include the question mark when pinging.

I assume you are posting from another device than the device that can't access the Internet and I assume that your posted log is from the device that cannot access the Internet ?

Can you disable your Windows Firewall on the device that does NOT have Internet?

Press the Windows Button and R simultaneously.

A new window called "Run" will open.

Type cmd​ and click OK

 

A new window will open with a black background.

Type netsh advfirewall set allprofiles state off

In that same window, press ENTER.

 

Can you now ping 127.0.0.1 and can you now access the Internet?

That command requiured admin permissions so I used an elevated CMD. 

The ping results are the same

I forgot to say, that command indeed requires Administrator privileges.

English is not my first language, do you mean with "elevated" that you did run that command succesfully with Administrator privileges?

Turn the Firewall ON using the command netsh advfirewall set allprofiles state on

So the device that does NOT have Internet connection is connected via Ethernet Cable AND Wi-Fi simultaneously and you can't access Internet with either??

When were you having this connection issue?

Did you recently install or uninstall something?

 

On the device that does NOT have Internet connection, go to ​C:\Windows\System32\drivers\etc​ and open the file called "hosts" with Notepad.

If you just open this file, it will automatically ask you what to use to open it, choose for Notepad.

The content of that file should look like this: (unless you manually added some entries or if you use something like MVPS HOST File)

 

# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host
# localhost name resolution is handled within DNS itself.
# 127.0.0.1       localhost
# ::1             localhost

Just a few things I noticed:

You can't ping 127.0.0.1, this is not good. Because 127.0.0.1 is something that should always be available to ping.

I don't know what this means in your case, but maybe your Network Interface Card (NIC) is broken??

 

How old is your Laptop?

Did it come with Windows 10 as Default or is this an Upgrade from Windows 8.1 or 8?

Firewall is turned back on.

I have ethernet and WiFi connected but no internet on either.

My etc\hosts file is the same as what you posted except for an entry at the end that reads

127.0.0.1  localhost

it does not have the # in front of it

The last install/uninstall was Norton 360 and I used the Norton Removal Tool from Symantec to do it.

I've seen Norton break Internet connections too many times so it was one of the first things I did.
