Notebook disturbs the WLAN?

I have a WLAN at home

Speedport LTE II router, DHCP server and AP,

Samsung Tab A

Lenovo Ideapad 320 Win 10

Asus F553M Notebook Win 8

Gigaset GX290 smartphone

Huwaei smartphone

Brother MFCJ480DW

all over WLAN in the network, the Brother printer with fixed IP.

The WLAN ran almost without problems for "years".

I recently bought another Lenovo notebook.

A V15-ADA with Win 10. However, this notebook causes a WLAN interference,

i.e. About 30 seconds after it has connected to my network, the network fails, i.e. None of my devices can still connect and I have to restart the router and deactivate the WLAN adapter of the V15.

I've already changed the Wi-Fi channels, but that didn't work.

Does somebody has any idea?

I guess there's simply too much if I counted correctly 7 devices in the Wi-Fi including telephone.

According to my documents, the part is 10 years old.

Years ago I had an older AVM box if there was too much tobacco shop in the Wi-Fi it always hung up.

Just try switching off everything else with the Lenovo notebook.

Otherwise a new router has to be found. Or switch off everything you don't need

I forgot to mention that: if I just connect the new Lenovo,

the same thing happens.
