That didn't do anything different.

I've sent you a message.

This should be visible on the forum if you check 'My Messages' and a copy should have gone to your registered email address.

I am willing to continue but I do get very frustrated when my brain my brain just quits working.
Could you possibly copy and paste your suggestions and comments into an email client and send it to me that way I can get it and follow directions from there.

Jimc,
No need to apologise.  I understand it was awkward to be switching between Windows and Linux multiple times in order to try things out and report back.

I certainly don't think any of my time was wasted.  For what it is worth, I thought you were close to making your Linux Lite connection work again and if you want to keep going just let us know.

Good luck.

I apologize for this, I do appreciate your attempt to help me.
I have been using personal computers since 1980's but my brain, what's left of it, can't cope with this anymore.
I am just too confused to do anything more.  The fact that I can't make any sense of what is happening and why.
I am sorry I wasted your time.
The Internet is dead to me.  It could be a wonderful tool but it is not.  I still have a Windows partition that still works so I can send and receive email and look at the news that will be enough.
Anyway, thanks for the effort I appreciate it.

Jim,

Does the system connect to the Internet using wireless while the ethernet cable is disconnected ?

To revert to DHCP, ideally you would undo any changes you made since it last worked using the ethernet cable.
If you don't know what changes you made, then the following steps may override them.

Click the network icon.
On a typical desktop, this is at the bottom right, near the clock but your desktop may be different.
Click 'Edit Connections'
You should see 'Ethernet' and 'Wi-Fi' and perhaps others.
Below 'Ethernet', you should see a named connection, typically  'Wired connection 1'
Highlight 'Wired connection 1', then click the cog icon.
On the window that opens, check that this is the interface you want to change.
Select the 'IPv4 Settings' tab
Click the 'Method' pull down and select 'Automatic (DHCP)', then save and exit out
You may need to reboot.

Jim,

Please try reverting to DHCP on your ethernet connection.
Or if you have not messed with the wireless interface set up, disconnect the ethernet cable and see if you can connect.

Let me be clear.
I want the internet to be usable.
My concern is that I will loose the desktop I modified in trying to fix the internet problem.

Jim,

Is that your Windows arp cache (arp -a)?

It looks like  a conventional network set up.

Jim,

It used to be on my router but I have tried to shift to one online because the router is COMCAST and I don't trust them.

I can't for the moment think how a remote online DHCP server would work for a typical home network as DHCP is a local protocol used to allocate valid IP addresses to a system on a LAN.  Perhaps you are confusing DHCP and DNS ?

1.1.1.1

Are you sure about this ?  If this is really the address used by the router, then your Linux system cannot communicate with the router as they appear to be on different subnets.  This would explain your symptoms.

I have tried both ways.  With the same result.

I edited it manually with text editor.

Would you be prepared to undo all the manual changes you've made and set your ethernet port to use DHCP to pick up an address from the router ?  If you cannot recall all the manual changes you've made, switching to DHCP may be enough by itself, but cannot be sure.

Just for comparison, are you doing similar changes when you boot the system as Windows ?
Please run Windows, open a terminal and post the results of
Code: [Select]
ipconfig
Code: [Select]
route print
Code: [Select]
arp -a

A few questions arise from that.

Do you set your network parameters manually (for example through the GUI or by editing system files) or are you on DHCP ?

I have tried both ways.  With the same result.

If you set manually, how have you done this ?

I edited it manually with text editor.

If you have a DHCP server, is it your router or another system on your local network?

It used to be on my router but I have tried to shift to one online because the router is COMCAST and I don't trust them.

What is the IP address of the router you would expect your machine to be using to get to the Internet?
