Laravel route group middleware issue -

i keep laravel routes in middleware auth group as:

route::group(['middleware'=>'auth'],function(){      route::controller('activities', 'activitiescontroller');     route::get('foo','foocontroller@getfoo');     ..... }); 

when try login access these page, unable login , url redirect login page again , again. if use constructor as:

public function __construct()     {         $this->middleware('auth');     } 

in controllers works perfectly. route group problem?

this works me , in route

route::group(['middleware'=>'auth'],function(){    route::controller('activities', 'activitiescontroller');  });  

then controller

<?php namespace app\http\controllers;   class activitiescontroller extends controller {      public function getindex() {           return 'you in;      }  }  

on attempt visit /activities redirected login page , , on success \activities 'you in'.
