O2 WLAN connection briefly interrupts at PS4?

I have had the following problem for some time: When playing online games on the PS4, the Wi-Fi sometimes interrupts for a second and throws me out of the game. Then the console connects to the WLAN again. In addition, sometimes the Internet stays completely away and the Internet is no longer displayed on the router. Does anyone have a suggestion on how to tackle the problem? Have the normal rental router from o2 and the PS4, I have already changed a lot, etc. I noticed that my PS4 is not recognized in my router settings as a standalone device like my laptop or my cell phone. It is listed under o2. Is that normal?

I'm very grateful for every tip!

Ok, so you mean I should lay a pipe?

WLAN is based on radio waves and can therefore be disrupted by other radio waves. All Bluetooth devices and microwaves interfere with the 2.4 GHz WLAN, through which most devices are connected. But other WLANs in the area can also disturb your WLAN or cause it to fail.

It is important that your router is not behind a wall or surrounded by objects. The router should be in a rather open room.

Despite all the precautions, an uninterrupted connection via WLAN can't be guaranteed.

If your router and your Playstation are in the same room, try switching to the 5 GHz network.

It is also partially susceptible to WLAN problems with O2
