Broadcom 94360CS2 - 5GHz WiFi not working?

I have High Sierra 10.13.3 installed, and I'm having some trouble getting 5GHz WiFi Access Points to work. I can connect to the one here at my house, but cannot access the internet whatsoever. Can connect to our 2GHz access point and can access the internet just fine, though. While not related, bluetooth works as well

What I've tried so far, without success: * resetting network settings and interfaces by deleting NetworkPreferences.plist and Preferences.plist in /Library/Preferences/SystemConfiguration * Adding patches to my config.plist with this guide * AirportBrcmFixup + FakePCIID.kext + FakePCIID_Broadcom_WiFi.kext * renewing DHCP lease (I thought it might be an IP address conflict. Every time I renew it, though, I get the same IP back) * manually setting my IP address on our network

The kexts I have in /EFI/CLOVER/kexts/other/: * AirportBrcmFixup.kext * AppleALC.kext * CodecCommander.kext * FakePCIID_Broadcom_WiFi.kext * FakePCIID_Intel_HD_Graphics.kext * FakePCIID.kext * FakeSMC.kext * IntelGraphicsFixup.kext * IntelMausiEthernet.kext * Lilu.kext * RealtekRTL8111.kext * Shiki.kext * SmallTreeIntel82576.kext * USBInjectAll.kext * WhateverGreen.kext * XHCI-200-series-injector.kext

Specifications, if that helps: * CPU : Intel - Core i5-7500 3.4GHz Quad-Core Processor * Motherboard : Gigabyte - GA-B250M-DS3H Micro ATX LGA1151 Motherboard * Memory : Crucial - 8GB (1 x 8GB) DDR4-2400 Memory * Video Card : Gigabyte - Radeon RX 460 2GB WINDFORCE OC Video Card * Network Card: BCM94360CS2 + this PCIe adapter

About to try rebuilding the kext cache to see if that helps, but if that doesn't work, I'm not sure what else to do. Any suggestions?

Also let me know if there's anything more info y'all need. Will consider
