Hi. I have Blueman, a Bluetooth manager and it works flawlessly with connecting my wireless earbuds to my laptop but the problem is that whenever I’d do so, my Wi-Fi cuts out on the laptop. How can I fix this? I’m not very familiar with both Bluetooth and Wi-Fi too much so I’ll provide any information needed. 
Yes, Bluetooth can affect the wi-fi connection. This is especially true for older wi-fi networks based on the 2.4GHz frequency band (802.11b). This is so because Bluetooth operates at the same 2.4GHz frequency band and signal overlap is possible. You should not connect bluetooth to both Phone as well as Windows as it affects. Try to disconnect one of the device and try… It may not affect your wifi connection.
The Bluetooth earbuds are disconnected from everything though. And our internet is I believe the Verzion 5g cube thing. Which is modern.
Your 5g cube thing may provide 5GHz wifi, but the laptop wifi card not be able to use it. The first thing you should look into is the wifi-/bluetooth hardware the laptop uses. The command lspci will probably list it, the command lspci -vv gives then info about the kernel module it runs for wifi/bluetooth. There may be configuration options for the module, or alternative (newer) modules that alleviate the problem. Next, one can search the forum for existing threads about that kernel module.

This is the device, as advertised. The module it uses probably is ath9k, you can check that with lsmod |grep -e ath9k. I see a couple of posts for your device on the forum, but no solution for the issue.
If you see ‘ath9k’ is used, one thing to try:
create a file: /etc/modprobe.d/ath9k.conf with the content:
options ath9k btcoex_enable=1
reboot and see if it helps. If it does not help, try explicitly setting the value to =0 in the file and reboot again. The parameter description is “btcoex_enable:Enable wifi-BT coexistence (int)”. Good luck.
