I use my laptop for network troubleshooting quite a bit. One thing that is a bit frustrating is that if I disconnect the ethernet cable from the laptop, then reconnect the cable, or if I have to reboot a router, my laptop does not reconnect automatically. In fact, it acts as if the cable is no longer connected, even though the link lights on the connected switch/router say otherwise.
For what it’s worth, I had the same issue in Ubuntu. I would just use the network manager and disable/enable the NIC, then it would work again. I can’t find that option for the wired connection in Antergos. SO, what I did today was to take down the driver then re-enable it with:
sudo rmmod r8169
sudo modprobe r8169
That works, but ideally, I’d just like the NIC to work as it is supposed to.
Any ideas to help me with this? According to lshw, the network adapter is
RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller
