There is a strange behaviour in my laptop, sometimes when I want to open a site, say stackoverflow.com, my browser stays "looking for" or "waiting for" that domain. Apparently doesn't find it right away.

What I usually do is ping that domain and after a moment the browser responds (sometimes its necessary reload the page).

I'm running Firefox 3.0.6 on CentOS 5.3, I have an ethernet connection to a WRT54G v5 router that is connected with the radio modem (Wifi).

I don't know if this is a very generic question, but I want to know if it happened to someone else out there.

does it happen only with firefox? – Svish Jul 16 '09 at 1:26
@Svish: Noup, it happens with other browsers too. – Eliseo Ocampos Jul 16 '09 at 2:26

What you are describing can simply be temporarily internet connectivity issues, such as interference when using wifi. When packets are lost you can easily be "stranded" for a couple of seconds waiting for a reply, and when you then ping the host, it tries to fetch the DNS information again, which is then cached.

Simply put: temporarily connectivity issues, resorting in delays and/or lost packets. Solution: encrypting your wifi would decrease interference, also check if anything else is using your bandwidth.

Yeah, that's what I supposed, but I wanted to be sure (by the way, how can I encrypt my wifi? Can you point me in the right direction? I see this could be interesting :) ) – Eliseo Ocampos Jul 16 '09 at 2:29
To encrypt your wifi you need to (in very simple terms) 1) find out what address your wireless router/switch has 2) open its IP address in your browser 3) find the security part of the settings. I made it sound extremely simple, but it's as simple as it sounds to enter the right input into the right fields. I recommend searching for your model and some tutorials, if not, you could always open another question. :) – Thor K.H Jul 16 '09 at 10:26
