Bluetooth keeps dropping connection to keyboard

I have a laptop running Ubuntu Mate 17.04.

I have a Bluetooth keyboard that I'm using with it because it's more comfortable.

Or, at least, I would use it, but, after about 5 minutes of use, the connection just drops. I can't simply reconnect, I have to shut off the Bluetooth keyboard completely, restart the Bluetooth service on my computer, repair, or other steps. There doesn't seem to be one set of steps that is guaranteed to make the connection work again, I just have to experiment over and over again.

If I connect the keyboard to my Android Tablet, it works flawlessly, so I am confident the keyboard is not the problem.

How do I get the keyboard to maintain a stable connection with my laptop?

Here is the output of lspci -knn | grep Net -A3; lsusb while the keyboard is connected:

$ lspci -knn | grep Net -A3; lsusb

I also seem to have to repair every time to get the device to work. Here are some additional outputs I get when trying to connect after pairing:

Solution 1:

Run this command and reboot

sudo tee /etc/modprobe.d/iwlwifi-opt.conf <<< "options iwlwifi bt_coex_active=N"

This should fix the issue with Wi-Fi and bluetooth coexistence.
