It looks like in countries that don't speak english the norm is router pronounced as 'rooter'... In Portugal I've always heard it pronounced 'rooter' as well, but I don't think it has some particular reason for it to be that way. Probably someone mispronounced it the first time and it became the rule??
Not so, because in many English-speaking countries it's also pronounced 'rooter': in the UK and Ireland, in Australia, New Zealand and South Africa as far as I know, and probably also India and Malta as those countries use British English.
