Hello,
As my internet sometimes is very slow I opened 192.168.1.1 (with that movistar/Spain specific page)
The local or the remote?
Local
Fibre or ADSL?
ADSL
that showed me that besides of my eth0-wired computer there are 4 other WLAN-IPs, although I, for the moment, do not have switched on any wireless device.
WLAN or VLAN?
WLAN
Is there a more or less simple way to find out if there are others using my WLAN - even for somebody who has not the slightest idea of how networks work?
Yes. Install "ntop", then start it "rcntop start", as root. Then point a browser to http://localhost:3000
the browser says that the page seems valid, but the connection was denied...
After a while, you will be able to see everything that is sending or receiving traffic, and some information and what is that traffic, and perhaps what type of machines they are.
If you have the IPs, you can find more about them with "nmap":
