Question Spilled Coffee on Pc, now GC-WBAX1200 wont work

[Polish-]

Like above Said, i spilled Coffee on my PC. Turned everything off immediately and took out my Graphics card. While taking out the graphics card i ripped the plastic cover off my PCIE x16 port because I panicked. Put my GPU in the x4 which got my PC running again. I also unplugged my WiFi card (which didn't get any coffee on it but I still took it out amongst the panic) and now the wifi won't work but the still Bluetooth does. The WiFi Card is in the PCIE 1 slot. My question is if it is fixable and what kind of damage it did to performance (because of the x16 to x4 swap)

Current components:
I7 4770K
GTX 970
Gigabyte H87-HD3

(Won't be able to upgrade because I'm currently still an intern)

1 x PCI Express x16 slot, running at x4 (PCIEX4)
* The PCIEX4 slot shares bandwidth with all PCI Express x1 slots. All PCI Express x1 slots will become unavailable when a PCIe x4 expansion card is installed.
* When installing a x8 or above card in the PCIEX4 slot, make sure to set PCIE Slot Configuration in BIOS Setup to x4.
