usb c hub blocks wifi signal

So I have this USB C hub to my MacBook pro 2017 and when I plug it into my computer the wifi and internet stop working. When I unplug it, the wifi signal instantly comes back. I need help with this if any one has an idea. I saw multiple ways to fix a USB dongle but mine doesn't have a long cable. Mine just has two USB C connections.

It would be fantastic if someone could help.

Not all hubs are made the same or compatible... Return it for one that works with your machine.

USB C dongle kills wifi

Why do I have difficulty with Wi-Fi or Bluetooth devices when USB 3 devices are attached to my computer?

Some USB 3 devices can generate radio frequency interference that can cause Wi-Fi and Bluetooth devices operating in the 2.4GHz band to have issues communicating with your computer.

Here are some tips to avoid this issue:

If your USB device has a cable long enough that you can move the device, place it away from your Mac—and make sure not to place it behind your Mac, or near the hinge of its display. The antennas for Wi-Fi and Bluetooth are located there, and USB 3 devices placed there might interfere with your wireless connections.

If you're using adapters or dongles on a Mac computer with Thunderbolt 3 (USB-C) ports, plug them into the front port on the left side of your Mac, or into the ports on the right side (if your computer has them). These ports are the farthest away from the antennas, making interference less likely.

To avoid interference on the 2.4GHz band using Wi-Fi, try using the 5GHz band instead. You can change this on your wireless base station. Bluetooth always uses 2.4GHz, so this alternative isn't available for Bluetooth.

Why does my wireless mouse or keyboard slow or not work properly when used with the hub?

Most USB receivers for wireless mice and keyboards operate in the 2.4Ghz band. When connecting the receiver to any USB 3.0 port there is potential for interference that can affect the devices performance. The most effective method is to add a short USB 2.0 extension cable between the hub and the receiver to mitigate the effect, and many wireless keyboards and mice come with such a cable for this reason.
