linux problem

<makos> Hello, I've a problem with my laptop. I recently formatted it and decided to install linux on it, as I removed my linux partition from my desktop because of space problems etc. I'm experimenting with various distros, but the problem appears on every installation. Yesterday I tried Crunchbang, installed it nicely, everything is fine, I try to configure the network - I use static IP - set everything up in /etc/network/interfaces, set DNS and routes, I can ping sites
<makos> but when I do apt-get update, most repos time out or it takes forever for them to time out (5 minutes per repo or something), not a single one is updated, so I can't perform a system upgrade or even install new software. OK, I thought it was a problem with this distro, installed Vector (Slackware fork). Same problem, can't update any repos, can ping stuff though, and now my X server seems to have problems, as I can't start browser (Firefox) because it gives me some
<makos>  error about not being able to find display, and I can't even find xorg.conf.d.
<makos> Woah, that's long.
<makos> Any ideas what can be wrong? The laptop is connected via ethernet cable.
<makos> To the same router my desktop is connected to and the connection here works fine.
<makos> Also, even though I'm using Google DNS, the ping times are awfully big, average ping to google.com is about 320 ms.
<makos> While here it is about 45 ms.
