With regards to the name-server bit, I honestly can't re-iterate this enough. It's amazing how many "My internet is slow" remarks really come down to DNS resolving slowly. My router has WAN failover, and I've had to manually tweak the DNS it chooses many times because even when a WAN is 'up', the DNS it uses might have latency exceeding 2+seconds for hours at a time (Comcast) even though the link itself is perfectly fast (125Mbit). Merely setting a different DNS source immediately shows off the full potential of the link. I still need to setup my own local DNS server so that I can be rid of this problem entirely. :(
