Internet connection keeps failing and restarting

Hello everyone,
This is my first post so I apologize if I put it in the wrong category or if I'm providing too much/little information with respect to what is needed.

I started facing a problem I believe is related to my NIC or it's driver, the internet connection keeps getting up and down for no apparent reason. Here is my driver after doing

lspci -v

:
::

 07:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 15)
        Subsystem: ASUSTeK Computer Inc. Device 8677
        Flags: bus master, fast devsel, latency 0, IRQ 38, IOMMU group 12
        I/O ports at f000 [size=256]
        Memory at f6504000 (64-bit, non-prefetchable) [size=4K]
        Memory at f6500000 (64-bit, non-prefetchable) [size=16K]
        Capabilities: <access denied>
        Kernel driver in use: r8169
        Kernel modules: r8169 

And after that I ran

dmesg | grep r8169

to make sure the driver was loaded and this was the response:

Re: Internet connection keeps failing and restarting

Try a different network cable?

Re: Internet connection keeps failing and restarting

Is the firmware for the chip loaded? Check "ethtool -i enp7s0".

I don't have one at the moment but I'll get one to test

Yes, the output was

driver: r8169
version: 
firmware-version: 
expansion-rom-version: 
bus-info: 0000:07:00.0
supports-statistics: yes
supports-test: no

This means the firmware isn't loaded, install linux-firmware.
