Seeing that an Intel network chip could be affected seams odd to me. From what I have seen online Intel controllers typically don't have issues. One command that might be of use to help diagnose lspci -vvv | grep -A 20 Ethernet this should display the kernel driver that is currently in use and some other info. On arch a few years ago someone had a similar issue with that Intel controller. https://bbs.archlinux.org/viewtopic.php?id=191981
EDIT alawi3d ya lspci should help with the beginning steps of what is going wrong. Also my laptop I am running Solus off of currently does use a Realtek Ethernet controller 02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL810xE PCI Express Fast Ethernet controller (rev 05)
