A medion laptop being used in germany aand set up in german logs off after a few minutes use.?

However the user does not have an isp due to her constant travel, instead she plugs into the telephone line. could this be the reason that constant logging out occurs ? thanks, michael
Answer
Is the laptop automatically dialling an unobtainable number. check internet explorer, ls, internet options, connections. on settings, advanced, there are disconnect options
