next_posts_link not visible on first page

Nvm I fixed it by using the a standard query:

    <?php 
$temp = $wp_query;
$wp_query= null;
$wp_query = new WP_Query();
$wp_query->query('showposts=6'.'&paged='.$paged);
?>

    <div class="row">   
        <?php while ($wp_query -> have_posts()) : $wp_query -> the_post(); ?>
