So I have been having some very weird behavior with my network since I installed arch linux.
After booting up the system the network seems fine until but once (seems randomly) slows down or completely stops working.
I discovered that there are two kernel modules that are used to control the network interface one being 8139too and the other one 8139cp, I figured out that my network seemed to work more reliably if I did modprobe -r 8139cp, and then modprobe -r 8139too then doing modprobe -f 8139too, the download and upload speed just increased to what I should be getting as usual from my ISP.
I thought that would fix my network problems but it didn't, the network is more reliable with the 8139cp module being disabled but it isn't what it should be it still would slow down after some time or completely stop working.
Here's some details:
ip addr

ip link set enp7s1 downand
ip link set enp7s1 up would help but it wouldn't fix my issue.
