Beforehand it was XP and there were no such problems. When I've installed Ubuntu such problems arrived. By the way, Skype is working quite good.
Also I can't install update packages.

Thanks:)

Pages are downloading too slow from 30 sec. to 1 min. Sometimes( not so often) they are opening quite fast. But sometimes pages are not downloading at all.

Thank you in advance.
