I am experiencing better responsiveness (e.g. when clicking a link) when surfing the net when connected through a router than directly to the wall. Its the same internet source, nothing should change.

What could be a possible explanation?

Did you set DNS servers on the router? If so did you also do the same on your host or are you accepting the DHCP distributed one? If you set them on your router and not on your host you could be experiencing delays from a slow DNS server. – Arctor May 17 '11 at 1:52
So if I explicitly set them on my connection setting, I might get better responsiveness? I'll give it a try, thanks. – ennetws May 17 '11 at 2:56
@ennetws: It's about the actual server addresses, not about where you set them. If your router has DHCP enabled, it likely also acts as a caching DNS server, allowing for faster responses than your ISP's servers. – grawity May 17 '11 at 5:05
@grawity: is their a way to cache locally on my computer? – ennetws May 17 '11 at 18:46
@ennetws: Yes. Windows already caches DNS responses; on Linux, you can either run nscd, or a full DNS server such as dnsmasq or bind. You should post this as a separate question, though. (Also, "there", not "their.") – grawity May 17 '11 at 19:13
