Hallo together,

I have a Thinkpad T410s with lubunutu.

Is it possible to make a hotspot with it, so I can connect an android tablet with internet?

I am not that familiar with lubuntu. But you can certainly do this with many different flavors of Linux.

Can you give output of these 3 commands?

lspci

Ok, You have an Intel Centrino, your kernel recognizes it.
It is device wlp3s0.

It looks like you are already using a 192.168.2.x IP address, so you don't want to conflict with that network.

I will use 192.168.7.x for your wifi network.
Make sure that wpa_supplicant is installed.
Make sure that NetworkManager-wifi is installed.

You can copy and paste this command.

nmcli dev wifi hotspot ifname wlp3s0 con-name wlp3s0 ssid rudi-hotspot password my$3cret

I would recommend changing rudi-hotspot to whatever you want your wifi network name to be.
I would definitely recommend you use a different password than my$3cret.
Your password has to be at least 8 characters long, longer is better.

Now we need to give your wifi interface a static IP address. You can copy and paste this also.

nmcli con mod wlp3s0 ipv4addr 192.168.7.1/24 connection.autoconnect yes

Now, assuming you have no errors, you should have a hotspot.
You can test this by typing...

iw wlp3s0 info

Or you can simply try to connect with your tablet or cell-phone.
It's possible we will have to add some routing to get to internet, but one thing at a time.

G'day @Rudl and welcome to linux.org :)

Change in syntax, we'll be looking for

wpasupplicant

and

network-manager-gnome

(and yes, I know Lubuntu is not GNOME DE)

First use

Code:
apt-cache policy wpasupplicant
and see what it says.

If it says something like

Code:
wpasupplicant:
  Installed: 2.4-0ubuntu6.6
  Candidate: 2.4-0ubuntu6.6
then it is already installed and can be used. If there is a blank space beside Installed, but something beside Candidate, then it can be installed with

Code:
sudo apt-get -y install wpasupplicant
On Network Manager

type in and enter only as follows

Code:
apt-cache policy network-manager
and then press your Tab key, it should generate a list (this is called Tab Complete). The list may look something like this

Code:
network-manager                    network-manager-openvpn-gnome
network-manager-dev                network-manager-pptp
network-manager-gnome              network-manager-pptp-gnome
network-manager-iodine             network-manager-ssh
network-manager-iodine-gnome       network-manager-ssh-gnome
network-manager-openconnect        network-manager-strongswan
network-manager-openconnect-gnome  network-manager-vpnc
network-manager-openvpn            network-manager-vpnc-gnome
If the GNOME entry is there, then where you stopped typing just start to finish it with

-gnome (just the -gn will do and then press Tab)

and when you have the completed entry, press Enter and see what it outputs.

If you get output that begins like this

Code:
network-manager-gnome:
  Installed: 1.2.6-0ubuntu0.16.04.4
  Candidate: 1.2.6-0ubuntu0.16.04.4
... you are in business. If nothing beside installed but an entry at Candidate, then install it as described above.

Hoping @dos2unix can run with it from here - wifi is not my strong point :)

Cheers

@wizardfromoz @Condobloke @f33dm3bits might have to help with that part. I don't use
apt that often.
I mostly use yum/dnf and pacman as my package manager, but when I do use a Debian based system I use apt-get instead of apt since apt is just a python wrapper around original apt-* commands. So I am guessing it's just warning reminding the user that it's just a wrapper and not be trusted in scripts?

What does this mean?
[email protected]:~$ apt list --installed | grep -i wpa_suppl
WARNING: apt does not have a stable CLI interface. Use with caution in scripts.
[email protected]:~$ apt list --installed | grep -i NetworkManager-wifi
WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

That may be so, but the packages referred to do not exist under Debian-based Distros.

wpa_suppl 's equivalent is wpasupplicant, and NetworkManager-wifi 's closest equivalent is network-manager-gnome .

It was early in the morning when I replied to that and is now as well so it I didn't catch what was asked of me. So I have all faith in you that you got this one. I'll just follow the progress here, I can always spin up my vm if needed. :)
