-

hello, everybody, i've got problem few days, , drives me crazy!!!

used acer 4741g, , updated pc 11.10 12.04 3 days ago, found its' hard me surf internet.

when use chromium, tell me webpage not available, because of dns lookup failed,
firefox, tell me server not found.
when used apt update or download softwares, tells me "something wicked happened resolving 'deb.opera.com:http' (-5 - no address associated hostname)".

tried set dns server address manualy, still not work.
of course, network ok, 11.10 works well, , friends' windows works too.
