I recently installed Arch, wifi has been messing around. Dropping and generally not connecting. I fixed it by ruling it was DHCP not getting a lease in time, I assigned a static IP and all is good. But for some reason every now and again I can't visit certain sites and domains(.net,.com) etc... If I use netctl to stop the profile then set my interface to down then restart prfile it works for a while again. I have no idea where to look for this. My /etc/resolv.conf has 4 nameservers (googles, and open dns) so they're good. Any idea where to look next?
