WiFi issues after attaching Controlblock on a Pi 3b+

[SuperPitendo]

Hey Community!

I ran recently in an issue with the Controlblock and the Pi 3B+. I have no wifi connection if the Controlblock is attached. Anything (incl. WiFi) works fine without the Controlblock.
I use the latest release of RetroPie (4.4 Stretch), have the original power supply and a Samsung Evo+ 64GB SD Card and the Controlblock2.

I used 3 different ways to get my WiFi to work without the Controlblock:

1. Via RetroPie-Menu --> Success
2. Via wifikeyfile.txt --> Success
3. Via wpa_supplicant.conf --> Success

If I do that with an fresh install and an attached Controlblock:

1. Via RetroPie-Menu --> Unable to connect
2. Via wifikeyfile.txt --> Unable to connect
3. Via wpa_supplicant.conf --> Unable to connect

I also used a pre-made image from petrockblock (Stretch 4.4 with the Controlblock driver preinstalled) but also with no success...

@SuperPitendo what is the volts and amps output on your power supply and what type of power supply is it?

[SuperPitendo]

Original Raspi power supplywith 5V 2.5A.

This is a hardware setup that already worked before with wifi. I didnt change anything (hardware and software). From one day to the other the wifi stopped working...
