I dual booted Ubuntu onto my T420, but seems like I have some Wi-Fi issues. It's normal half the time, half the time it's slow, and sometimes, it just won't work for a minute or so. I'm not sure whether it's the drivers or something, and I'm new to Linux, so I have no idea on how to troubleshoot. 3rd party drivers are enabled already. Thanks in advance.

If your WiFi is slow when using Bluetooth, try adding the following to /etc/modprobe.d/iwlwifi.conf and reboot:
