https://bbs.archlinux.org – I tried the same with a spare cable that I had and the WIRED LED on the router turned on! It seems weird because it was working just fine yesterday, but probably reconnecting it to the router did the trick.After that, I still couldn't ping anything, so I did:# ip link set eth0 up # ip addr add dev eth0 # ip route add default via this got me to ping IPs just fine. Then I added my ISP's nameserver to /etc/resolv.conf and everything works now:# Generated by dhcpcd # /etc/resolv.conf.head can replace this line # /etc/resolv.conf.tail can replace this line na (HowTos)
