Q: Network issue with airport express
Hello, I need your help. As soon as I connect my airport express wireless to my existing wifi, the hole network crashes. If airport express is connected via ethernet, it works. How can I fix this issue ?

Do you want your Express to connect to your network wirelessly, or with an Ethernet cable?
If you want the latter: leave it connected with Ethernet, and "hard reset" the Express - press its tiny reset pushbutton and keep it depressed, about five seconds, until its LED flashes rapidly.
Then, select this from your Wi-Fi menu:
AirPort Utility should launch and configure your Express more or less automatically.
The first screen you will probably see in AirPort Utility will be this:
The key parameter to verify is this one:
At the top you should see the words "Setting up this AirPort Express to extend ... using Ethernet".
If you see the following (or something similar to it) instead:
... that's not what you want, if you intend to "extend" your network using Ethernet.
If you want to "wirelessly extend" your network, don't connect its Ethernet port to your router. Doing so will bring down your network.
If none of the above screenshots seem applicable, explain what you are seeing and I will try to point you in the right direction.
