Well, every time that I use my internet through of router with wire or wireless, any ubuntu version or another linux o.s. that I test work correctly; However, when I eliminate the router and use directly my internet, the linux o.s. function perfectly. Whats happen with my router? When I said "do not work correctly" means: some pages dont load, like facebook.com and this site(yep, now I use Win7 to make this post).
And my Android show the same problem, facebook app dont load images, askubuntu dont load correctly too like my notebook with ubuntu or desktop.
I tried Chromium and Chrome and Firefox.
