Wi-Fi NIC is failing after about an hour - Surface Pro 3 | running 5.1 Hera

Question

I have a driver issue or something that is causing my Wi-Fi to intermittently fail. This is a Microsoft Surface Pro 3 tablet. Here's the Wi-Fi NIC config:

crimKid@ElmnlryOS-SP3:/etc/pm/sleep.d$ sudo lshw -C network
[sudo] password for crimKid:         
  *-network

I checked the output of dmesg but there was far too much and I didn't know what to grep for. How can I fix this?

Update: I did find this when running grep against dmesg

crimKid@ElmnlryOS-SP4:~$ dmesg | grep -i firmware
[    0.186908] Spectre V2 : Enabling Restricted Speculation for firmware calls
[    0.226436] ACPI: [Firmware Bug]: BIOS _OSI(Linux) query ignored
[    1.870961] [Firmware Bug]: Invalid critical threshold (98)

I googled the above, but apparently there is some argument as to whether or not this is a bug...? https://bugzilla.kernel.org/show_bug.cgi?id=69921
