The internet on my laptop has not worked so well for 2 days. It shows a WLAN signal, but with only one bar. I can only see YouTube videos with long loading times every 30 seconds and I can no longer access Internet sites. In addition, I have full Wi-Fi access on my PC and cell phone. What could that be?
On a bad WLAN antenna in the PC
To the title question: Yes, you have problems with WLAN.
Radio is unstable and there can be umpteen reasons why the reception situation can change.
If you value stability and speed as "no brainer", no matter how you twist and turn it, there's no way around LAN cables.
In the other case it is worth familiarizing yourself with physics => sparks.
Only with the knowledge will you be able to better assess where the problem lies on site.
You write, it's only been like this for 2 days. So it was better once.
Go with the laptop directly to the WLAN router, is reception better then? It must have 100% signal strength (i.e. All bars) close to the router, it does not have 100% signal strength because an antenna cable inside the laptop is no longer properly connected (loose contact) or the WLAN adapter is defective (you could replace one then Use WLAN USB stick on the laptop).
Maybe you are using a Wi-Fi repeater, maybe it has failed?
Router and laptop restarted? Sometimes works miracles.
