No internet connection

Please follow https://help.ubuntu.com/community/WirelessTroubleshootingProcedure

Hi and thanks Manfred for you help, but before Evan starting procedure 1 it says "Please first connect your network card to the wireless router using an ethernet cable (also known as a LAN cable) and apply all updates". I can`t get internet at all !! Does that matter at all ??

To gain usable information from the procedure your system needs to be connected to the internet.
Do you have any possibility to connect the system in question to the internet (e.g. connecting it to the router via a LAN cable, or mobile phone tethering, an additional WLAN USB stick, ...)?

I've tried tethering (USB C to C cable between my working mobile phone and the system in question) and also I tried a dongle (USB stick with a wifi areal) and still internet no go. It's strange that in settings it says that the visible network is connected but at the top right corner of screen there is no internet icon displayed. I thought my proton VPN might of been the trouble but after deleting it, that made no difference 🙁

Does any one know what's happened with my no internet icon that is suppose to be displayed in top right corner of my laptop screen ?? Thanks muchley for thinking about it.

The missing icon not relevant. The real problem is that networking does not work, neither with WLAN nor with tethering.

If you issue the command

lspci -nnk | grep -iA3 net

do you see network devices listed? And are there lines with "Kernel driver in use" shown?

Hi Manfred man, sorry for this late reply, as I have been else where. There is an Ethernet controller listed with the Kernal driver in use: r8169 and a Network controller listed with a Kernal driver in use: iwlwifi

It is hard to help without seeing the full output of the troubleshooting procedure, but as long as there is no network connection it is hard to make it available.

When you issue the command

ifconfig

which IP addresses do you see for that system?

Yes indeed, the no network is causing many major problems. Command 'ifconfig' not found, but can be installed with: sudo apt install net-tools : which required a network to install New Packages and therefore failed. It said try '--fix-missing?' but command not found. Then after command 'apt-get update'
Reading package lists... Done
E: Could not open lock file /var/lib/apt/lists/lock - open (13: permission denied)
E: Unable to lock directory /var/lib/apt/lists/
W: Problem unlinking the file /var/cache/apt/pkgcache.bin - remove Caches (13: Permission denied)
W: Problem unlinking the file /var/cache/apt/srcpkgcache.bin - Remove Caches (13: Permission denied)

The error messages like "Could not open lock file ..." are caused because you did not use sudo for an admin command.
"sudo apt-get update" will help with the permission problem, but it will most probably fail with "repository server not found".

"It said try '--fix-missing?'":
That message is a bit misleading. It is meant that you might try
sudo apt-get install --fix-missing
which in your case probably will not help either.

Do you have an Ubuntu installer at hand (either on DVD or on a bootable USB-stick)?
I suggest that you try booting from such installer in the "Try Ubuntu without installing" mode to test whether networking is possible in that mode.

No I have not a Ubuntu installer, sad to say.

Hi Manfred, is it true that you think my no internet issue has been fixed with your last reply to my needed help request. Where do I get a Ubuntu installer as I last said that I have not a Ubuntu installer. I'm at a lost for what to do next

Can I download the Ubuntu Installer onto a USB stick via my android device ??

I rebooted the router and the laptop but nothing changed with still no internet to be had. Can I d/l Ubuntu Installer onto a USB stick via my android device and then what I'm not sure ??

"Can I download the Ubuntu Installer onto a USB stick via my android device ??"

Apart from some methods that require rooting your android phone, the following sequence of steps should work:

Use a web browser on your android device to download the Ubuntu installer iso file and store it locally on your android device (if you have enough free space left).
Connect the android device to your computer system in the USB Storage mode, such that you can copy the iso file from the android device to the Ubuntu system's hard disc.
Disconnect the android device from the Ubuntu system.
Plug an empty USB stick (or one whose contents can be deleted) into the Ubuntu system.
On the Ubuntu system create a bootable USB stick (e.g. with USB-creator, rufus, or etcher, or other program).

If you need further details, do not hesitate to ask.

I've always wanted to root my old samsung galaxy note 9. Where to find a better OS for to do that ?

That's off-topic here. Use a web search.

Where is the place to go to get the Ubuntu installer iso file ?

https://ubuntu.com/download/desktop
or
https://releases.ubuntu.com/

Thanks and Cheers for that

Rito I've got the download and have copied that to the laptop hard drive. Now how to do the bit about on the Ubuntu system create a bootable USB stick (e.g. with USB-creator, rufus, or etcher, or other program). Where do I find them programs ??

I hope that one of these is already installed on your system
