Wifi slow on Airport Extreme when connecting ethernet devices

I have an AirPort Extreme 802.11n (4th Generation) as router (firmware 7.6.4). It's connected to 100mbit/s fiber.

Wifi connection is great. But if I connect my Mac Pro with an ethernet cable the wifi connection gets really bad on my Macbook Pro. Streaming video is almost impossible. If I connect my Time Capsule via ethernet the internet connection gets unusable on all devices regardless wifi/ethernet. Websites take minutes to load!

Settings are DHCP & NAT (200 ip addresses), wifi is a WPA2 Personal. I have no idea where to start.

Has anyone had a similar issue?

Be sure to disable Wi-Fi on your MBP when connected by Ethernet. You should only have one or the other connection when accessing a network or the Internet.

Both computers are used. Wifi on MBP and ethernet on Mac Pro. Wifi i always disabled when using ethernet.

And if I connect Time Capsule it just stops everywhere. Wifi on MBP & iPhones, ethernet on Mac Pro and TV.

And I really want to extend my wifi network with my Time Capsule, but that seems impossible.

If you power-off the MBP, and just have the Mac Pro connected by Ethernet to one of the available LAN (opposing arrows) port on the 802.11n AirPort Extreme base station are there any issues with this connection? If not, temporarily connect the MBP using an Ethernet connection to another available LAN port on the Extreme, leaving the Mac Pro connected and running. Any issues now?
