Network problems

Awaiting your response.

Good evening,

For a few days I've been trying to integrate a TP-Link router into my network, which I need to control my model railway with the Z21 Digital from Roco/Fleischmann via WiFi.

Following the instructions, I typed the necessary address into the browser's address bar a few times and I keep getting the message:

Error: network timeout

The server at 192.168.0.1 is taking too long to send a response.

Could it be because the connection attempt is being blocked by the firewall and can I temporarily disable the firewall to contact the required site?

The others in the Z21 community obviously don't have this problem.

Would be grateful for a corresponding information
