Dear Linuxers, I just want to close this issue by thanking everyone who chipped in with help and attempts to solve the problem Unfortunately the mistery will go on, because my student solve the problem by changing his ISP server. He told that the problem was solved immediately, as we predict and tested (via mobile and the neighbor's internet). So, I cannot run any more tests, and I'll stay curious about what really happened. My bet: the "homebrew ISP" has a DNS problem. Thanks.
