Question Rpi4 taking out my internet connection ?

[RileyMax1]

Not sure if this is router or rpi related
Trying to set up a freshly flashed Rpi4 for home assistant and everytime I plug the Ethernet cable into my router, I lose internet altogether.
Modem is an Asus rt-ax58u, other connections are my pc, my partners pc and a home base for my security cameras.
Any suggestions would be muchly appreciated

and a home base for my security cameras.

What do you mean "home base"? btw, Asus rt-ax58u is a router, not a modem.

First come to mind is that you have an IP address conflict between devices.

Check and list IP addresses for your router, RPI4, both PCs and "home base"for security cameras

You can connect to your RPi wirelessly instead of (not in addition to) hardwired.

When you create your RPi image, do you specify the WiFi SSID and password? And also enable the VNC server? Once your RPi is booted, you'll have to go to the router to find its IP address. Once the IP address is found, you can use a VNC viewer to log into your RPi.

If your internet is still getting hosed, it's your RPi.

Another thought, you're connecting the RPi to one of the yellow RJ45 ports, not the blue one, Right? 😱
